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.
