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.”
