An Edwardian terrace in Muswell Hill, the project is also the home of our Studio Founder Ben Ridley (Award-Winning Passivhaus Architect).The project achieved an impressive estimated 80 percent energy saving compared to standard homes of comparable size.It also has an organic, minimalist finish at a modest budget.

The original structure of the house was revealed, its modest beauty celebrated. Design features include timber structure, triple glazing, a continuous airtight layer and insulation to the entire building envelope.Walls were insulated externally at the side and rear, and internally at the front with wood fibre.Insulating internally at the front has allowed the original Edwardian facade to be preserved.

Masonry nib walls were retained at ground floor to avoid energy-intensive steel box frames.Natural materials including stone, timber and lime plaster were used throughout rather than cement-based products.The rear extension was built in highly insulated 172mm SIPS and all existing building elements achieved a Passivhaus standard U-value of 0.15 or better.An MVHR system provides pre-heated fresh air, creating a warm and comfortable home.The system also filters the incoming air, removing pollen, diesel particulates and NOx to create a healthy indoor environment.
