Circular prefabricated


The SirkBo is a part of the innovation project SirkTre, which works towards a circular value chain for the Norwegian wood industry.

The project will pave and simplify the path to a circular zero-emission house, by combining already established principles from the prefabricated house industry such as modularity and standardization with low energy and circular design strategies, such as e.g. "Design for disassembly" (DFD) and Design for adaptive reuse (DFAR). All measures must ensure a positive environmental footprint in the building's life cycle.


Circular design strategies within architecture are in the starting phase in Norway. The process requires a joint effort from the entire construction industry's value chain, developers, and politicians to meet the EU's environmental goals by 2050. SirkBo is supported by The Green platform Initiative.

HZA Sustainable vision

In recent years, HZA has won, designed, and completed several innovative and sustainable wood projects, from larger urban development projects to smaller houses, all with wood as the main material. We have worked with complex construction tasks as well as transformation tasks within low-energy houses, passive houses, and zero-emission houses.

Circular chain

In a circular economy, waste is primarily raw material for new production. This entails a significant reduction in the amount of virgin resources used, more efficient utilization, and increased reuse, repair, and recycling of what still becomes waste.

In the long term, a circular economy means that no waste is created in the first place, and thus no waste industry as we know it today.
