Hasletre

A global first – fully demountable, reusable timber office.

The new headquarters for Save the Children Norway is found in Hasletre, a 2,772 m², four-storey office building built entirely built from timber, and the world’s first demountable and fully reusable mass-timber office.

The project addresses the climate crisis and urban renewal challenges, reactivating a former industrial area and completing a public square, benefiting both the local community and Oslo’s sustainable development goals.

CLT and glulam form the structure, with prefabrication cutting assembly time by 75%. Dry timber-to-timber joints eliminate glues, silicones, and most steel, enabling disassembly and reuse. Reused interior elements and salvaged equipment enhance circularity.
With 60% lower emissions than traditional offices and a design-for-disassembly model, HasleTre defines a global model for circularity in timber architecture.
