Kv Återbruket

Groundbreaking construction

On Litteraturgatan, climate and environment are in focus and two of the buildings, Kv Återbruket and Kv Omställningen, are paving new paths for sustainable construction. The Återbruket neighborhood is a unique project where the goal is that at least half of the built-in material will consist of recycled materials. Based on Lendager’s fine vision, liljewall has further developed the project in collaboration with Framtiden Byggutveckling and the contractor NCC. The house contains 66 apartments with planned occupancy in 2026, and unique to the project is that it is designed based on the materials available on the market. The project has the flexibility to be able to replace new materials with recycled materials if possible, which the building permit allows for. For example, the HDF floor joists and steel frame from the former IKEA department store in Kållered have been dismantled for the first floor and the glulam beams and facade sheet metal have been taken from the Isdala ice rink in Kortedala. The apartments will be painted in light colors on the inside and will have parquet floors and fully tiled bathrooms with tiled floors. A small portion of the interior materials are also planned to come from recycled sources.

On behalf of NCC, RISE has carried out quality assurance of the perforated decks. Through a number of drill cores from the concrete, the compressive strength of the concrete, durability and tensile testing of reinforcement cords were tested. All perforated decks showed high quality concrete and low degradation due to carbonation. They are estimated to be able to be used for at least twice as long as they are today.

Classic design techniques for a refined, qualitative whole

The block consists of two houses that create a semi-open block. The entrances to the block are continuous from the street to the social courtyard. Up on the lower part of one of the houses, a common roof terrace with an orangery is also created where tenants have the opportunity to grow crops or enjoy the sunshine. The apartments, which have light from at least two directions, are reached via a wider entrance balcony that is supported by the character-creating recycled glulam columns. A thin canopy over the entrance balconies lands lightly on top of the glulam columns and creates a weather-protected place for residents facing the courtyard. Recycled glulam columns, sheet metal mountain facade and the thin canopy create an elegant volume and give the block its own character.

Although the planning regulations and available materials have been given a large part of the design, the houses also embrace classical design approaches. Both houses have a clearly marked ground floor. The facade structure is framed in a symmetrical framework that allows for a variation in window sizes without changing the facade expression. Where reuse of windows is not considered possible, the facades have a repetitive and coherent window arrangement. In addition, the roof has a marked eaves and roof overhang and the block has many careful details around the windows and on the facade, which creates a processed, qualitative whole.

Clear rooms and lush plantings

In the courtyard, paved paths wind along the houses and around the courtyard’s common areas. Between the green, lush plantings, clear spaces are created that invite play and meetings for the residents. Natural plantings along the private patios form a boundary between the private and public and frame the courtyard area. The parking area is framed by low walls, which creates a functional clarity and safe demarcation to the courtyard. Stormwater is led to open rain beds that are integrated into the planting areas, which benefits the local climate and the green space factor.
