A private house built with cross-laminated timber panels (CLT) has won the Sustainability category in the Royal Institute of British Architects Spirit of Ingenuity Awards. It was also commended in the residential category.

Cavendish House in Cambridge was designed by Mole Architects of Ely. It uses CLT panels from KLH of Austria for the core structure of the building, with glulam beams and columns employed to allow an open plan ground floor.

The three-storey building meets Passivhaus standards on insulation performance and energy use and, due to the CLT, boasts low embodied CO2.

The engineer on the project were Ramboll, which has previously worked on such large-scale CLT projects as the Norwich Open Academy and St John Fisher School in Cambridge. The company won the TRADA-sponsored Market Development category in this year’s TTJ Awards.

Earlier this year Cavendish House shared the Small House of the Year prize in The Daily Telegraph British Homes Awards with another timber building, Bigdwelle from dwelle ltd.

Cavendish House will be featured in the next edition of TTJ sister publication Timber & Sustainable Building.
