Lakehouse Construction has started work at Hackbridge Primary School for the London Borough of Sutton, on an exciting new building which will be the UK’s first Passivhaus Plus certified school. The project is a two storey new build design and construction utilizing a timber frame system comprising classrooms, a hall, library, studio, and food technology centre, and providing space for 420 pupils aged 5-11 as well as a nursery provision. The project will meet Passivhaus Plus standards as well being net zero carbon certified.

The Passivhaus design standard will be utilized to create a highly sustainable environment to learn in, as well as a healthy and educational environment to learn from. The new school will integrate learning about sustainability by growing food, supporting active travel, reducing energy and waste and provide well-designed environments for outdoor learning and play.

The substructure includes a patented Isoquick insulation which offers superior thermal performance and acts as permanent formwork for the oversite, with a timber frame comprising a specialist cellulose insulation blown into the cavity of the frame, post installation. Sustainable features of the build include roof-mounted photovoltaic systems, warm and green roof coverings and a ground source heat pump. The windows are a triple glazed, timber and aluminium construction offering exceptional thermal performance, and the building will be clad externally with sweet chestnut timber fins.
