A mix of natural sciences, technology, health, and entrepreneurship. A foundation for collaboration and innovation. A modern school and an inspiring workplace. That’s the essence of Widerströmska Upper Secondary School in Huddinge.

Just like the NEO and Technology and Health buildings, Widerströmska is part of the life science cluster that has taken shape in Campus Flemingsberg in recent years. Tengbom has been the lead architect for approximately 50,000 square metres here between 2012 and 2019.

The school, named after Karolina Widerström, Sweden’s first female medical doctor, now occupies one floor of the NEO building. Here, future researchers and entrepreneurs learn in close collaboration with the academic and healthcare institutions surrounding them.

A life science hub for future innovators

Bright and inspiring classrooms

Inside, light, space, colour, and openness define the NEO building—and these qualities also shape the school’s interior. While the upper floors house cutting-edge research labs for Karolinska Institutet, the Widerströmska floor is designed to be a creative and inspiring learning environment.

Students and teachers can write directly on the walls, and large glass partitions ensure that natural daylight reaches every corner of the study spaces. A yellow-green carpet, running through all the classrooms, enhances the brightness even further.

Design details create a cohesive identity

In collaboration with LINK Interior Architecture, Tengbom developed a material and colour scheme that aligns with the identity of the rest of the NEO building. Subtle design details connect the school’s interiors with the upper floors, including spiral staircases and accent colours in ceilings, doorways, and furniture.

A safe and social learning environment

Beyond classrooms and lecture halls, the school features a central gathering space known as Arenan, as well as a gym, science labs, café, multipurpose hall, and staff rooms.

A key priority in the project has been to foster a sense of social security and community. The spatial layout encourages interaction between students and teachers, with transparent environments and open sightlines.

“There are no hidden corners anywhere. Staff rooms are evenly distributed throughout the school, where students naturally spend their time.”

Client: Ersta Diakoni
Location: Södermalm, Stockholm
Assignment years: 2017 - 2023
Gross area: Approx. 24,000 m²
Partners: Emma Olbergs Design

Together with Ersta Diakoni, Tengbom is developing Ersta Hospital on Södermalm in central Stockholm. With an evidence-based approach and in close partnership with healthcare providers, the organization, patients and family members, we are creating an industry-leading healthcare environment where people will feel (almost) completely at home.

Ersta hospital

Ersta Hospital opened on the heights of Södermalm in 1864. In 1907, Axel Kumlien designed a new building for the hospital, which relocated nearby. Fifty years later, Tengbom designed major additions and extensions to the block. In 2014, an architectural design competition launched for Ersta Nya Sjukhus—the new Ersta hospital. The goal was to create a design that honored the historic identity of both the surroundings and the hospital’s key areas of expertise. Nyréns Arkitektkontorwon the competition and, together with RATIO, developed a concept that elegantly followed the topography and reflected the area’s scale and classical aesthetic. They led the project until the building permit application phase.

In 2017, Tengbom was tasked with managing and carrying out the project – and developing the function and design of the new hospital. Work was conducted in close partnership with the Ersta Diakoni Program Office, and in light of the modified and granted building permit, with the City of Stockholm and its architecture office.

Connection to the city

The new hospital rises some six stories up the hill from one of the island’s busiest streets, Folkungagatan. At eight stories, the building’s highest section runs from east to west along the crest of the hill, in harmony with the characteristic buildings nearby. Two projecting buildings – one facing south toward Folkungagatan and one facing the old hospital building to the north – form two lush courtyards.

Even inside the new hospital, the connection to the city is the primary theme. From the wards and rooms to the hallways and large rooftop terraces, the surrounding city and vegetation have a constant presence. The city landscape is part of the healing environment. The glassed-in hospital lobby is a large, bright and welcoming room rising up three stories, with views of the surroundings.

Architecture, exterior character and facades of the hospital

The interior and exterior of the new Ersta hospital create a sense of cohesion. Patients and visitors should feel welcome, safe and well cared for. In a classic interplay of large windows and horizontal and vertical features, the facades are made of metal and ocher brown anodized aluminum in a carefully chosen hue.

The materials change in character and reflect light, while the colors complement the yellow and brown plaster facades of the surroundings. Windows match the facade color, creating a sturdy and uniform expression that enhances the urban quality. A grayish-red flamed granite foundation reinforces the building’s cohesive design.

Tengbom’s starting point is to create healthcare environments in which patients are the focus, and where the architecture supports medical development and new working methods.

Somewhere between a hospital and a home

If you imagine a scale ranging from the public, often impersonal spaces of large hospitals, to a private, home-like setting, the aim is for the new Ersta hospital to be a balance between both worlds. It should be infused with personality and a sense of care-giving, paired with professionalism and trust.

Ersta hospitalInterior

The new Ersta hospital is characterized by calm, quality, and genuine natural materials like wood and stone. The details are thoughtful and the colors are classic, light and earthy. The color and material concept was developed with inspiration from Ersta’s visual legacy in an exciting collaboration with Emma Olbers Design.

The bright, glassed-in lobby runs through the building like an axis. A spacious open staircase defines the backdrop, creating a welcoming focal point with a sense of space and clarity. Patients, visitors, and staff share the hospital lobby and the adjacent elevator hall, reinforcing an open and inclusive atmosphere.

Ersta hospitalOutdoor environments

Designing the hospice ward required extra care. Patients and their families should feel at ease and spend quality time together. A private, green rooftop terrace offers a peaceful retreat. A swing by the elevators and a playroom for children add warmth and comfort to the environment.

In front of the main entrance at Folkungagatan, the courtyards and rooftop terraces are significant in terms of design. A fundamental part of our task is to make it possible to see nature from multiple stories in the building.

Ersta hospitalUnique operational development with long-term solutions

The new Ersta Hospital delivers resource efficiency, flexibility, a good working environment, and a strong focus on patient safety. The floorplan improves efficiency by using just one elevator hall with short corridors. Stacking hospital units keeps related functions close. The busiest departments, with the shortest visitation times, sit nearest to the entrance. In-ward recovery plays a central role in the hospital’s care concept. Patient rooms prioritise proximity to windows. The layout places the patient and family area by the window and the care provider area by the corridor. Staff conceal medical equipment and materials or integrate them into the surroundings. This creates a calmer and more patient-friendly atmosphere.

Ersta hospital

With Ersta Nya Sjukhus, the new Ersta hospital, the team at Tengbom aims to contribute to world-class medical care. The building extends the hospital’s long history and strengthens its presence in the city. It will play a key role in Stockholm’s continued growth.

Location: Stockholm
Years of commission: 2009–2018

Partners: White, Reflex & Dot arkitekter among others
Competences: Healthcare, Landscape, Interior design, Project management, BIM & 3D Illustration, Accessibility

Welcome to Nya Karolinska Solna – one of the world’s most sustainable teaching hospitals. Probably Sweden’s most comprehensive hospital project ever is also the single largest engine behind the development of Hagastaden – a new part of Stockholm city and a Scandinavian centre for Life Science.

A great investment to meet the care challenges of the future

Stockholm’s region is expanding at a furious rate. The population is expected to increase by 350,000 people between 2010 and 2020. The number of children and elderly is growing faster than other age groups at the same time as our life expectancy also continues to grow.

Most of our current hospitals were planned in the 1960–70s. They are not prepared for the current or future rapid development of medical technology, medications, new treatments or procedures. Nor do they meet the requirements of the modern patient. Just like in other industries, the need for interdisciplinary activities have increased also within the healthcare services not least the conditions for exchange of ideas between disciplines such as medicine, research and education – so called Life Science activities. The need for dedicated and flexible premises is overhanging.

To be able to meet the challenges of the future health care, Stockholm’s county council is making one of its biggest investments ever. We are preparing for a real boom in health care construction and NKS is a central element of this investment. The hospital will welcome its first patients in 2016 and reach completion in 2018.

Collaboration in the White Tengbom Team

NKS covers about 330,000 sqm and includes 730 patient care rooms, 35 operating theatres, and advanced technology for highly specialised care. The project also meets strict environmental requirements and presents enormous challenges for all partners involved. It is Sweden’s largest public-private partnership and the country’s most advanced BIM project. NKS is also the first hospital to achieve environmental certification according to both Swedish and international standards. To address the architectural challenges, we formed the White Tengbom Team in 2010. This project-specific company brought us together with the architectural firm White to design the hospital.

Around sixty of our architects, engineers and project managers have been involved in the project during the seven years that the project has been going on so far.  The work will go on including a follow-up until the opening of the last stage in March 2018.

Flexible environments for sustainable development

Nya Karolinska Solna is designed to last approximately 100 years, even though future healthcare needs remain uncertain. With rapid medical advancements and technological leaps in mind, we planned the facility for maximum adaptability. Its flexible design allows for changes and renovations without disrupting surrounding activities.

High ceilings, robust joists and capacity in infrastructure and technical supply are examples of important investments, which allows the activity to develop in a sustainable manner over time.

The patient in focus

The key words for the entire NKS project are ”putting the patient first – always”. All the planning and design has been based on the patient’s safety, integrity and comfort which means that every patient is cared for in his/her own room with adjacent hygiene room. The single rooms offer greater integrity and safety and reduce the risk of both contagion and incorrect medications. The design of the rooms makes it possible for the healthcare professionals to work as a team with the patients and to closely collaborate with scientists and students who can come and visit in a completely new way. The health care is moved closer to the patients.

A healing atmosphere within Nya Karolinska Solna

We have taken great care to design healthcare facilities that have a positive impact on the patients. Light and volume shape the internal atmosphere, creating generous public spaces and numerous meeting places where people can mingle. In the interior, we have focused a lot in harmonious colours and natural materials.

The exterior of NKS showcases a minimalist elegance with a façade of glass, steel, and white tiles. The design of the hospital building is based on a block structure with right angles that is a continuation of the neighbourhood of Stenstaden right next door. A glass structure connects five buildings. Entrances and activities shall have as open a relationship as possible to surrounding streets and squares.

The healthcare blocks connect to the research buildings in the north and Karolinska Institute’s new lab in the west. Between the health care and research facilities, the Academic street runs, tying together the New Karolinska Solna with the Karolinska Institute, which bridges Solnavägen via a new pedestrian and cycle bridge.

World leading Life Science cluster in Hagastaden

Stockholm County Council’s investment to meet future health care challenges included the vision of creating a Scandinavian centre and a catalyst within Life Science – a place where the business community, academia and clinical research, health care services can meet and interact. In the NKS project, the collaboration between health care, research and education has been the starting point for the architecture.

Nya Karolinska Solna will also be the single most important motor behind the development of Hagastaden – the new district where Solna and Stockholm meet, and which when completed will offer approximately 5,000 new homes and 50,000 jobs of which just over 6 000 at NKS. We are creating a science city for cutting edge education and research under the common name Stockholm Life. The main building of the hospital will form the focal point of Hagaplan, the new town square.

Awards and Recognitions

NKS was nominated for the World Architecture Festival in the Completed Buildings: Health category in 2019 and was ranked fifth globally by Newsweek in 2025.
