As Gothenburg continues to grow, so does the demand for housing. There are many ways to address this, but one sustainable solution is to convert existing buildings. In Kvarteret Generalen, unused attic spaces are being transformed into 24 new apartments — preserving history while creating much-needed homes.

In 2019, the municipal housing company Bostadsbolaget received a tip from its staff about unused attic spaces in one of its properties in Haga. A feasibility study soon confirmed that the high ceilings — reaching up to six or seven metres — could accommodate 24 new apartments, while still leaving room for new attic storage areas.

Since then, twelve loft apartments have been completed on Södra Allégatan, and another twelve are on the way.

“The attic space our staff noticed in Haga had impressive ceiling heights. The study showed that we could create 24 apartments while still providing new storage areas in the attic”, says Per Orshammar, Project Manager, Bostadsbolaget

Each apartment is unique in layout and size, ranging from 31 to 35 square metres. All feature an open-plan kitchen and living space. The next phase of the project will begin in 2024, with the final twelve apartments set to be available for rent by 2025–2026.

We’ve had to be creative while showing great respect for the building’s cultural and historical values.

Kvarteret Generalen – a historic landmark

Haga is one of Gothenburg’s oldest districts, known for its cobblestone streets, small squares, and historic buildings. It’s a highly desirable area, but new construction is nearly impossible. Instead, the focus is on adapting existing buildings, as seen in Kvarteret Generalen.

Originally built in 1866 as a children’s hospital, the property was designed by architect Frans Jacob Heilborn. In 1910, four additional stone buildings—ranging from four to six storeys—were added, designed by Ivar Tengbom and Ernst Torulf. Today, Haga’s charm attracts both residents and visitors, blending a vibrant café culture with historic character.

Attic conversions in two phases

The first twelve apartments are now complete, marking the first phase of the project. With the second phase underway, another twelve apartments and additional storage spaces are being created.

“What makes this project particularly exciting is the challenge of preserving and enhancing the original architecture while creating modern homes,” says Helena Elisson, architect at Tengbom.

“We approached the project with a solution-driven mindset—balancing creativity with deep respect for the building’s cultural heritage.”

By preserving Ivar Tengbom’s original architectural vision, we have created new living spaces without compromising the historic integrity. Achieving this required careful material selection and thoughtful design. The project began with a feasibility study and a building permit process to ensure a seamless transformation.

Smart and sustainable solutions

By reusing existing structures, the project reduces environmental impact while creating valuable new homes for Gothenburg residents. Helena emphasises that collaboration with Bostadsbolaget was key to solving challenges within the complex structure of the building, especially in areas like ventilation and chimney placement.

“Together, we explored a variety of solutions. In some apartments, we designed skylights, in others dormer windows,” explains Helena.

“One innovative approach was to install a raised floor, making it easier to route plumbing and ventilation systems. The white interiors and light-stained wooden floors further enhance natural daylight and create a modern feel.”

Transforming the future of housing

The Kvarteret Generalen project demonstrates how historical buildings can be preserved and adapted while contributing to the housing market. By creating 24 new homes within an existing structure, the project showcases a sustainable and innovative response to housing shortages.

“While 24 apartments won’t solve Gothenburg’s housing crisis, it’s a great example of how we can rethink and repurpose existing spaces,” says Helena. “It required technical expertise, creativity, and a deep respect for the building’s historic significance.”

The former upper secondary school in Tensta, a heritage-listed building of the highest cultural value, is set to reopen as Campus Tensta under the management of Hemsö. Blending late modernism and brutalism with influences from Asian architecture, the school has been carefully restored by Tengbom, with a strong commitment to preserving its original identity.

Tensta 1 Tensta 2

Designed by Gösta Uddén, the school was inaugurated in 1984. Some call it “the last truly grand school built in Sweden”, while others argue it should be designated a listed building. Since 2018, it has stood empty, with rumours of demolition causing concern among both architectural experts and the public. However, Hemsö’s vision is the opposite: the school will be carefully restored, ensuring its architectural integrity remains intact.

Letting go of the ego

“As an architect, there’s always a desire to make your mark on a project. But when working with heritage buildings, you have to set aside your own vision in favour of preserving the original structure,” says Josefin Larsson, architect and business developer at Tengbom, specialising in restoration, cultural history, and adaptive reuse.

A cultural restoration detective story

Tengbom has led the extensive renovation, which aims to bring the school back to its original condition while meeting modern requirements for accessibility, acoustics, and fire safety.

Together with Reichmann Antikvarier, Tengbom has mapped and documented the building’s cultural and historical attributes. As an expert in heritage conservation under Swedish planning law, the antiquarian ensures that all modifications comply with strict preservation regulations.

Patterned concrete and pagoda-inspired roofs

The original complex, designed by Uddén, includes the school, the Tensta Träff community centre, a library, and later a sports and swimming hall. Together, these three buildings form a triangle.

The facades feature high-quality materials such as red brick, patterned cast concrete, laminated wood, and black-painted steel. At the heart of the school, a glass-roofed winter garden floods the interior with natural light. Architectural elements include open-air corridors, diagonally protruding staircases, and dramatically curved roofs inspired by Asian pagodas.

Stockholm’s City Museum has classified the school as a “blue-listed” building—the highest level of heritage protection, meaning it is considered an essential part of Sweden’s cultural heritage.

“For Campus Tensta, this means an absolute prohibition against alterations that could compromise the building’s historic character,” explains Josefin.

Thoughtful additions that blend in

Each space within the school has been assessed for its cultural significance. Architecturally valuable areas are marked as “rooms of special character,” allowing only minimal changes. Other spaces, such as classrooms and restrooms, are being renovated to meet modern standards while preserving the original design.

Tensta 10Campus Tensta’s classrooms are being upgraded with new acoustics, lighting, and accessibility features. Suspended ceilings are being replaced, and all restrooms will receive new tiles, sinks, and toilets. However, in areas such as corridors and the winter garden, everything is being restored to its original state.

“The principle behind the renovation is gentle transformation—we work with the building’s original logic,” says Josefin. “Any additions should blend in rather than stand out, and we prioritise reusing materials whenever possible. New technical systems will be discreetly integrated, and interventions will be minimal yet highly functional.”

Tensta 11 Tensta 8Campus Tensta – reviving the original vision

In 2021, Hemsö acquired both the school and the Tensta Träff community centre. The goal was to create Campus Tensta, a space where education and culture come together.

Tensta 12Their vision is to bring together secondary and adult education, higher education, cultural initiatives, and entrepreneurial ventures under one roof.

“We are truly excited to bring life back to these incredible buildings. Our goal is for Campus Tensta to enrich both the local community and Stockholm as a whole—contributing to education, culture, and creativity,” says Johan Einarsson, project developer at Hemsö.

The first step begins in autumn 2024, when Järva Gymnasium moves in. The newly established foundation-based upper secondary school will mark the start of a new era for Campus Tensta.

Frälsningsarmén’s heritage-listed building on Kungsholmen, Stockholm, was in need of both restoration and modernisation. Through a careful balance of reuse and reconstruction, the goal was to preserve its identity while adapting it for today’s needs. But first, one crucial question had to be answered: what lay hidden behind the walls?

A building waiting to be rediscovered

Hantverkaren 18, home to Frälsningsarmén’s 6th Corps, was built in 1911. Over the years, the organisation’s needs had changed, yet the facilities had not kept pace. The kitchen was too small, the lighting inadequate, and the overall wear and tear significant. The work environment needed improvement, and the building required a comprehensive restoration that honoured its past while supporting its future.

With a guiding principle of “preserve and adapt,” the renovation focused on enhancing both function and aesthetics while maintaining the building’s historical character.

A space for many purposes

The updated facility needed to accommodate a variety of functions, including:

  • A flexible assembly hall with a balcony for worship services and large gatherings
  • Meeting rooms, corridors, kitchens, storage, showers, and changing rooms
  • A multifunctional dining room, central to Frälsningsarmén’s mission, where meals are served to those in need

Messages from the past

To uncover the building’s true identity, we had to look back. The investigative phase, known as anamnèsis, the Greek word for “recollection” — guided every decision. The team studied oral histories, archival drawings, historical documents, and photographs, combining historical research with insights from Frälsningsarmén’s staff.

We reopened the skylights in the dining hall to let light into the premises. Photo: Sten Jansin.

Then, the team conducted a physical investigation—scraping paint layers, uncovering hidden spaces, and evaluating what could be restored, reused, or reconstructed. During the process, they discovered hidden doors, which were carefully repaired and reinstated. Long-buried wood paneling was uncovered and restored, while paint analysis informed a subtle, historically inspired color scheme. Sealed-off skylights were reopened, allowing natural light to once again fill the dining hall. Additionally, the checkerboard-patterned linoleum flooring was replaced, bringing back the original wooden design.

Time, knowledge, and respect

Restoring a 100-year-old building requires more than just technical expertise, it demands patience, precision, and deep respect for history.

By carefully weaving Frälsningsarmén’s legacy into the present, we ensured that its mission, history, and identity remain visible and meaningful for generations to come.

Sundbyberg water tower

A well-preserved Tengbom classic

Client: Sunbybergs stad
Location: Sundbyberg
Project type: Restoration, Reconstruction
Assignment years: 1912, 2009–2010

Our founder, Ivar Tengbom, designed the Sundbyberg Water Tower, which was completed in 1912. This early concrete structure is fully clad in Helsingborg brick, featuring cross-bond patterns and bold ornamentation that reflect the national romantic ideals of the time. Nearly a century later, in 2009, we took on the challenge of adapting the tower for public use, bringing new life to a landmark that had long stood without a clear function.

Sundbyberg water tower is remarkably well-preserved and holds great architectural and historical value. It is a prime example of the utility and industrial buildings constructed around the turn of the 20th century.

As Sundbyberg’s most iconic landmark, its distinctive, monumental character remains a striking presence in the cityscape. When it was first built in 1912, the tower stood as a symbol of Sundbyberg’s rapid modernisation.

A careful transformation

The renovation respected the building’s cultural heritage, using historically accurate materials and methods.

Externally, the design team preserved the tower’s original silhouette by making only minimal changes. Inside, they carefully maintained the original layout and built-in features. They meticulously cleaned and repainted the grand wooden staircase, all windows, and other carpentry details with linseed oil paint in their original color. Additionally, they designed and crafted a new entrance door to match the original design.

Today, parts of the tower serve the public, now housing a café and exhibition spaces.

A breathtaking view from Sundbyberg’s water tower

Nomination and awards: Nominated for Helgopriset 2023

Some buildings are fortunate enough to enjoy long and eventful lives. Over time, they may change functions, adapting to new needs while retaining their essence. When we developed Vreta Kloster, our aim was to create a vibrant and inviting destination — one that would open up Klosterhuset to all.

At the entrance to Berg’s locks outside Linköping lies Sweden’s first monastery, originally founded as a Benedictine convent. Today, only the ruins and Vreta Kloster Church remain. But there is also Klosterhuset — the former grain storehouse of the nuns. The site has long been a popular destination, drawing visitors for both religious and cultural experiences.

“For historic buildings like this, the key to longevity is meaningful use. When they serve a purpose, they stand a greater chance of being cared for and developed over time,” says Magnus Almung, lead architect at Tengbom.

Revealing Klosterhuset

Upon arrival, visitors are first greeted by the impressive church and its ruins — a natural focal point in the landscape. Behind the towering trees, Klosterhuset was once barely visible. There was no clear approach to the building, and when visitors finally found their way there, they were met with closed doors, unable to experience the beautiful vaulted interiors.

“The goal of the renovation was to enrich Vreta Kloster as a visitor destination with engaging exhibitions—sparking curiosity about the site’s architecture, archaeology, and history, all leading up to a well-earned café break,” Magnus explains.

Now, Klosterhuset is more visible. Carefully pruned trees allow glimpses of the building from the gravel square between the church and Klosterhuset. A winding path leads visitors between the trees and along the building’s long side, guiding them through a newly created opening in the old stone wall, directly opposite the church entrance. At the southern gable, a gravel courtyard connects to the historic stone walls.

Restored with care

Klosterhuset, dating back to the 13th century, was already in good condition. Some minor cracks in the masonry were repaired, and the roof — recently re-laid with traditional wooden shingles—was left untouched. To ensure year-round use, we carefully adapted the building, adding glazed doors within the existing openings.

The four wooden doors on the eastern side, remnants of Sigurd Curman’s early 20th-century restoration, were likely part of the original structure. “To improve the indoor climate, we added slim steel-framed glass doors behind the wooden ones,” Magnus explains.

The challenge was balancing functionality with preservation — enhancing comfort without compromising the historic wooden doors or the building’s unique, atmospheric light.

Thoughtful accessibility

With ground levels already nearly flush with the thresholds, accessibility improvements required minimal intervention. A reversible modification allowed for step-free entry, and the automatic door mechanism was discreetly embedded in the floor. The southern hall was designed as a flexible space, suitable for concerts, lectures, confirmation classes, exhibitions, and even a café. A discreet wire system along the walls enables flexible lighting and display arrangements.

“With materials and patina this rich, our approach had to be careful—installing heating, lighting, and electrical systems in a way that respected the building’s integrity,” says Magnus.

Hidden technology, visible heritage

The large limestone slabs covering the floors had been loosely laid in sand, making it possible to lift them, conceal wiring beneath, and put them back without damage. In the northern hall, now home to the stone museum, the team carefully leveled the original flooring. In the southern hall, where the floor was more uneven, they added a new layer of limestone. The stone museum also received upgrades, including improved display cases, signage, and lighting.

“We wanted Klosterhuset to be open to visitors during the day,” Magnus adds. “But even when it’s closed, its beauty remains on display. Subtle lighting highlights the interiors, making them visible through the glass doors.”

A glimpse inside

We added an interior glass bay window to the stone museum, allowing visitors to peek inside even when the building is locked. The nearby red-painted stable now serves as a visitor facility with toilets, a preparation kitchen, and staff spaces. A simple serving hatch offers coffee straight into the monastery garden.

The project also introduced a new storage facility for churchyard management near the southern visitor car park. Designed as a traditional agricultural building, it complements the surrounding 19th-century structures. A timber frame supports the structure, while horizontal laminated wood panels create the exterior. Carefully crafted details enhance the façade, corners, and eaves. Painted in Falu red, the building seamlessly blends into its historic setting.

Klosterhuset reopened to the public in spring 2019 — ready to continue its long and remarkable story.

Säby Gård is situated next to Säby lake in western Järvafältet’s nature reserve. The farm is listed, of great historical value and an important destination for visitors in Järfälla municipality. Today, the farm is used as a riding school among other things. For this project, we developed proposals both for a new stable block and a preservation and maintenance plan for the long-term management of the listed monument.

Säby Gård‘s manor house was erected in the 17th century from drawings by Nicodemus Tessin senior. The beautiful farm comprises of two wings from the 17th century as well as outbuildings and warehouses from the 19th century. The manor also features a baroque park with a pond and a tree-lined avenue. The facility houses horse riding stables, a pre-school, a home and a café.

Modern stables with a foot in the past

We planned the project and prepared work descriptions for the restoration of several key areas. The work included the old stables and the factor’s house. As antiquarian consultants, we also guided the replacement of pipes. In addition, we oversaw the restoration of the gallery and the stone portals of the manor house. To support the farm’s future management, we developed a preservation and maintenance plan. This plan covers the entire historical environment.

Stjärnorp Castle Ruins is not only an important cultural heritage site but also a beautiful example of how contemporary architecture can enhance and highlight historical buildings. Led by Erik Wikerstål from Tengbom as the chief architect, the project has been praised for its sensitive balance between preservation and renewal.

Since 1789, Stjärnorp Castle Ruins, located just north of Linköping, stood unprotected following a devastating fire. Through extensive restoration and modernization, it has been safeguarded against further decay and prepared for future generations. Today, the ruins play a significant role in the cultural and tourism landscape of Östergötland.

Award-winning craftsmanship

The restoration of Stjärnorp Castle Ruins has received widespread recognition, earning the Östergötland Architecture Prize in 2023. The jury commended it for “exploring the boundary between restoration and architecture and how we approach our cultural heritage.” Indeed, the restoration has been characterized by exceptional craftsmanship, with every detail executed with great care and respect for history.

Protective roof and elegant interiors

The ruins have been fitted with a discreetly integrated roof that shields the historic walls without impacting the exterior aesthetics. Inside, visitors are greeted by an elegant interior where modern materials such as wood, corten steel, and glass emphasize the original architectural features.

The large window openings now feature individually designed glass panels. Each panel is precisely tailored to fit the uneven shapes of the walls. The balance between history and modernity is both striking and subtle. This is evident in the newly added spiral staircase in the tower and the carefully crafted corten steel details.

“We aimed to create something that feels contemporary while rooted in the ruin’s history. The goal was for the old and the new to enhance one another, and I’m very pleased with the result,” explains Wikerstål.

Good architecture makes cultural heritage accessible

The restoration of Stjärnorp Castle Ruins shows how architecture can make cultural sites more accessible. Careful interventions have given the ruins a new function as a destination. More visitors are drawn to the area, while the project demonstrates sustainable restoration in practice.

“We hope that Stjärnorp Castle Ruins will become a place where people can meet and experience both the past and present in a unique way,” Wikerstål concludes. “By securing the ruins for the future, we ensure that coming generations can share in our collective cultural heritage.”

It began with a simple sketch amidst fierce international competition, and the rest is history—and the future. Originally built in 1939 as Folkets Hus in Borås, the building was refined by Tengbom and reopened in 2018 as Borås Congress—a modern conference facility that preserves the values of its past.

Following a challenging prequalification process involving 60 architectural firms from around the world, Tengbom advanced to an invited design competition. The battle for Borås Congress had begun in earnest, and it was time to flex some muscles—or was it? Amidst advanced visualizations and meticulously packaged concepts, a simple hand sketch by Bo Karlberg stood out. In 2012, it became clear that the assignment was ours.

“We were entrusted with the project because we understood both the architecture and the business.”

“The proposal focused on developing a state-of-the-art conference facility for the entire region, restoring Gunnar Nilsson’s modernist entrance motif, and maintaining the building’s role as a community gathering place in Borås,” Bo explains.

Borås CongressBorås Congress

Accessible and flexible for all types of meetings

While the starting point for the project was preservation, the goal was to create a modern meeting place. Today, Borås Congress is one of the few Swedish buildings specifically designed for meetings, as opposed to many concert halls and arenas across the country.

The facility offers everything from intimate rooms for small gatherings to larger conference spaces for up to 1,000 guests. The building’s character is present throughout, as are its newfound flexibility and accessibility. The number of levels in the block was reduced from 36 to just 7 (!), and the floors were designed to allow for multiple events of different kinds to occur simultaneously.

Borås CongressBorås Congress

Borås Congress – a bridge between past and present

The new congress building spans an entire block across four volumes. Along Österlånggatan, Gunnar Nilsson’s bold entrance motif—carefully restored from layers of 1980s cladding—once again aligns with the iconic functionalist buildings of Borås.

Along Allégatan, the architecture adopts a more subdued and scaled-down character. In contrast, the new performance and hall volume, with its main entrance facing Robert Nilsson’s Place, makes a bold impression. Its shimmering facade of gold-anodized expanded metal stands out against a deep blue backdrop.

At the transition between old and new lies the glass wedge housing the congress foyer. Here, stucco lustro, an ancient Italian marbleizing technique, meets ultramodern pre-printed glass railings. The result is a meeting place that is both exciting and symbolic.

“It’s a powerful feeling to see visitors gathering and connecting here today,” Bo concludes. “That has always been the goal of the project for nearly a decade: the meeting of people.”

With the ROT Award-nominated Campus Vasastan on Karlbergsvägen 77 in Stockholm, we transformed a charcuterie factory facing possible demolition into a modern, vibrant campus with three upper-secondary schools in one building.

The building was constructed at some point between 1954 and 1971. It was a charcuterie factory first and later became an office. Today, it is a downtown upper-secondary school for 1,800 students and part of the solution to Stockholm County’s need for 15,000 new upper-secondary places by 2027. In 2019, a courageous Hemsö acquired Kadetten 29, which is now run by education company AcadeMedia.

Campus Vasastan
From a charcuterie factory to an office block – to three upper-secondary schools in one.

“There weren’t any tenants at first. With extensive experience under our belts, and expertise in upper-secondary schools, we worked with Hemsö to develop a detailed plan, a concept and an idea for an attractive school that they could show to potential tenants. Almost like working with branding,” says Karolina Lorentzi, a Tengbom architect with extensive experience in educational settings.

Stockholm’s future: reduced climate impact

Transforming a large building and giving it a new purpose requires significant effort from many players. Care for the environment is evident in the project through reuse, recycling, and high energy targets to contribute to a lower impact on the climate. But of course, the greatest environmental gain comes from the carbon dioxide emissions avoided by not tearing down a building. The on-site greenhouse is built with recycled materials, as is the carcass of the building.

“Reusing an existing structure while creating good settings isn’t just true sustainability. It’s also an efficient use of time – and an incredibly exciting project,” explains Karolina.

Many technical challenges

A reuse project on the scale of Campus Vasastan means facing one technical challenge after the next. The depth of the building presented a challenge for working with daylight, while a low ceiling in several areas required both extensive technical installations and space. Securing solutions for emergency exits and escape routes in a building with many people posed another technical challenge. Additional zones enabled us to make adaptations for accessibility.

Like an archeological dig

Demolition inside an older building that has undergone multiple updates is a bit like an archeological dig. Problems arise as you progress and innovative construction solutions must be found quickly.

Campus Vasastan
Campus Vasastan encompasses around 12,000 square meters on seven stories. Arranging the puzzle of logistics, flows, acoustics, light and structure is a complex process.

“For example, as we cleared off the framework, we found it was in really bad shape. A pillar was broken and construction had to stop. It was hanging, as if by a thread, and we had to call in an engineer. We didn’t have all the blueprints from earlier renovations, and so much of the steel was affected. Novogruppen did an incredible job as general contractors here,” explains Charles Davis, lead architect for the assignment.

Efficient flows and structure in every detail

What makes a school well-functioning? Well, among other things, it comes down to the handling and planning of larger spaces, acoustics, social areas, large-scale flows and logistics, accessibility, air, daylight, fire protection and safety. Campus Vasastan has an area of about 12,000 square meters on seven stories, both above ground and basement and semi-basement levels. It has 53 classrooms and three athletics rooms.

“For me, the twist came when we realized we could tear off the entire garage roof, which would give the atrium another level. That was when I knew this was going to work. It’s the heart of the transformation – it allowed us to create flow, context and a social aspect,” adds Karolina.

Campus Vasastan
A natural hub that serves many purposes. Presentations, events, studying, or simply a place to hang out.

What was the garage entrance is now the main entrance and it leads into the heart of campus – the welcoming atrium. This gathering place offers an overview of the four lower levels, from floor -1 up to floor 2. The street level is home to a reception, café, library, student health center, and open areas. The cafeteria, large kitchen, recycling and waste room, athletics center, and changing room on floor -1 can all be accessed from the atrium.

Campus Vasastan
Construction began in 2021 and the school welcomed its first students in fall 2022.

The upper floors contain light-filled classrooms designed for concentration, along with study spaces, administration offices, a teachers’ lounge, common areas, and flexible subject-specific classrooms. The team designed the open spaces to allow zoning and adaptable furnishings, creating rooms within rooms.

The third-story outdoor space, covering approximately 1,000 square meters, features a greenhouse. Students and staff can use this educational space as an extension of lab work, for gatherings, or simply as a lush green retreat.

How did we do it?

“Campus Vasastan was a success thanks to an open partnership with plenty of momentum from all players involved, with an open-minded approach and a clear common goal,” says Karolina. “Tengbom brought in expertise from an early stage and we were able to be on site throughout the project.”

In an understated concrete and wooden structure that is typical of its era, Vendelsömalm School opened in Haninge in 1966. With an aim to “preserve and reuse as much as possible,” the school has now been updated to meet contemporary needs and requirements. 

The original Vendelsömalm School consisted of a robust building with a few distinctive and sturdy materials, like untreated concrete and pine, brown linoleum and terrazzo. A minium red accent color added contrast and recurred in the windows and wooden doors. Several renovations and technology installations were then carried out.

A return to the original quality

Vendelsömalm School has 600 students from preschool to ninth grade. In 2018, the school underwent an extensive and necessary renovation, replacing the ventilation and electricity. Tengbom was tasked with renovating and upgrading the main building and modernizing the accessibility and functionality of the floor plan.

“We wanted to retain the feel of the original, with cast concrete on three half-levels,” explains Tove. The 110-meter-long main hall, with its beautiful stairway, holds everything together. At the same time, we wanted to restore the former look of natural materials and recreate them in conversation with a contemporary style.

Greater security with a new floorplan

When we adapted the premises for their purpose, we moved the reception and principal’s office closer to the main entrance. The break room was also moved to improve student safety. The special education classroom, student health, library and teachers’ lounge were all placed centrally in the building.

“Vendelsömalm School isn’t a listed building. However, we brought in one of our restoration architects early on to document and analyze the building,” says Tove. “That study was the basis for several decisions.”

We let in more light

The team installed energy-efficient windows with transoms that resemble the originals, along with awnings and natural-colored facade panels. They also made the main entrance and two schoolyard entrances accessible and replaced the entryways. Inside, they updated all installations and converted the cellar into a fan room. A new elevator now provides access down to the basement floor.

For more light, accessibility and safety, the new doors are glazed. The doors are all orange once again, like the original color. A total renovation of the surfaces entailed new floors, a new false ceiling, acoustic solutions and fresh paint. There is now also a garbage room and a loading yard.

Renewal from historic walls

“The goal was to clean and restore the concrete in the main hall,” says Tove. “We decided to remove the old murals, which students painted with latex paint in the 90s. Unfortunately, it was hard to carry out such an extensive restoration of concrete. Instead, it was painted in concrete-like colors with the preserved rough texture of boards at the base. Old dents and the history on the walls can add a lot of beauty and invigoration.”

The false ceiling in the big main hall features untreated wood, restoring the room’s original concept. The walls in the combined assembly hall and cafeteria now have untreated wood panels, enhancing both aesthetics and acoustics.

Sound is subdued by the building – not the kids

In the open student areas, the team refreshed the original wooden furniture with modern, inviting seating and tables. They designed the adaptable module system for easy adjustments.

“The design of the tables and benches allows students to move freely without fixed roles or assigned seats,” says Tove. “The space adapts to different needs and situations. A school should be welcoming to all.”
