A Certified Passive House Classic in Cambridge, designed by Architype, featuring energy-efficient construction with structurally insulated panels, tailored for comfort and longevity, completed in 2017.
Certified Passive House Classic
Tim Ross from Architype met the challenge of a long, narrow site, and district plan setback requirements, for this couple relocating to Cambridge who wanted a comfortable, energy-efficient house, that would meet their needs as they aged.
The layout, structure, services and aesthetics of the building tightly work together to create a simple yet extremely high performing building. Construction was with structurally insulated panels (SIP). A beautifully crafted and designed family home.

Denis & Judy from Cambridge
“I love the fact that you can just move from room to room, and the temperature is the same, night and day, summer and winter. This winter we haven't put the heat pump on, and no electric blankets, no heated towel rails, no underfloor heating, and it's really nice.”
