Sketch of the week: Passivhaus for north Essex

This week’s #buildingdoodle sketch is by Chris Exley, director at Water Lane Architects, and shows a zero-carbon, Passivhaus scheme at concept design stage for a village site in north Essex. He says: “The design developed from analysing the site and surroundings and developing a passive solar plan and section for the building, making optimal use of solar and ground source ‘free’ gains, plus solar power generation for the house and for electric vehicle charging. The site layout also includes a half-size allotment area for growing fruit and vegetables, a reed bed treatment and filtration area, and surface water attenuation via pond and ditches.”
