Circle House: Denmark’s first circular social housing units

October 25, 2022

Circle House is one of Denmark’s most ambitious and visionary circular projects. The project is Denmark’s first social housing units built according to circular principles.

The world’s first circular social housing units

With Lejerbo as the client, the Circle House project is constructing the first social housing units built according to circular principles. This means, among other things, that the building has a higher degree of flexibility during its lifetime and that 90% of its materials can be disassembled and reused at a high value.

The building is designed by a collaboration studio comprising 3XN/GXN, Lendager and Vandkunsten Architects. The project consists of 60 social housing units in Lisbjerg north of the city of Aarhus. In addition to serving as housing, Circle House is a scalable demonstration project that creates and spreads new knowledge about circular construction across the industry and silos. Therefore, the project brings together over 60 different companies across the entire value chain.

In September 2018, the project inaugurated a demonstration unit that shows the building system in 1:1 as a proof of concept and an exhibition of circular building materials. The project has been tendered out on market terms and the finalization of the project has been won by a team of local companies: Torntoft & Mortensen (contractor), Rum (architects), Sweco (engineers). In the autumn/winter of 2021, the team will start construction of the buildings and the project will be finished for inauguration in 2023.
