East London-based Techtonics Architects has completed this Passivhaus in a conservation area in Hackney, east London
The 100m2 two-storey house has been built on an infill site and due to planning regulations was required to be set half a level down from the street.
The house’s bedrooms are located at the lower ground floor with an open plan living space above.
The building, which is constructed from concrete at the lower level and has a prefabricated cross-laminated timber upper storey, is clad in brick and zinc.
Architect Bernard Tulkens, commented: ‘Quality of construction and simplicity of details are key to achieving Passivhaus: low air leakage construction requires careful attention to all the joints between construction elements, so the whole building team needs to understand the principles of the construction.
