Hemspan® is a construction technology business developing bio-based, circular systems to capture and store atmospheric carbon in buildings.

We're using these methods in our developments, working with a housing partner. Currently on-site at Oak Tree Rise in Burrough Green, Cambridgeshire. Phase 1 is due to complete five hemp homes by the end of 2025, ready to welcome residents to a sustainable and healthy living environment.

Our hemp insulation products offer low water vapour resistance, outstanding thermal performance and flexibility, replacing the need for polystyrene, glass and mineral wool insulation. It is ideally suited for internal, thermal or acoustic insulation and is perfect for sustainable construction.
