The task is to develop a multi-storey housing project that sets new standards for eco-friendliness in Danish construction. As a demonstration project under the “From 4 to 1 Planet” initiative, Green Hub House acts as a living laboratory for low-emission materials, shared-use concepts, and energy-efficient operation. The project is realised in close collaboration between Himmerland Housing Association, Aalborg University, NIRAS and C.F. Møller Architects.

The architectural solution unites simplicity, flexibility and community. Four sustainability principles – Sufficiency, Efficiency, Circularity and Sharing – form the methodological foundation. The result is compact homes with high living quality and low resource use, adaptable to changing housing needs and social dynamics.

Reuse and Timber Modules

The buildings are constructed using prefabricated timber modules and are based on screw foundations, significantly reducing groundwork and climate impact. The façades feature reused terracotta facade, while reclaimed hollow-core slabs and ventilation components minimise material waste. Simple architectural strategies – such as recessed access balconies, façade fields and greened sections – create identity and variation.

The landscape is an active part of the project’s sustainability profile, with focus on rainwater management, biodiversity and green communal areas that foster social interaction. Across functions and scales, the design prioritises robustness, adaptability and sufficiency.

Energy and indoor climate solutions such as heat recovery and optimised hot water systems ensure low consumption and high comfort in use. Green Hub House is developed within current regulations and technological frameworks and contributes new knowledge to future climate-friendly housing.
