The Long Barn

The Long Barn was designed as a three-household, four-generation family home, built to robust Passivhaus Standards.

It was completed in 2016, following detailed design, specification and project management by Sustain-by-Design, and forms our main office.

The design approach involved erecting an independent internal timber frame, highly-insulated both within the frame, and on its external face.

SIPS panels were employed to form the roof deck, and the floor slab was heavily insulted beneath.

Underfloor heating and MVHR are complemented by good airtightness and triple-glazed and sealed joinery.

The build took 12 months, and the budget was near to £2000/m2
