Marsh Flatts Farm aims for Passivhaus Plus certification

Work is underway on the construction of a private new-build dwelling on the site of an old farmhouse in rural Derbyshire. The building is being constructed from a combination of cavity wall masonry and SIPs panels, and is aiming for Passivhaus Plus certification.

The single biggest surprise was the difficulty in finding a suitable contractor. I’d assumed there would be plenty of local builders looking for a project where they could learn all the low-energy building skills they’d be able to charge a premium for on future projects, but that simply wasn’t the case. Out of 10 requests for quotation there were only 2 viable responses, and only the chosen contractor had experience of achieving Passivhaus levels of airtightness."
