Designed by McLean Quinlan Architects, the Devon Passivhaus combines contemporary architecture with a rustic outdoor setting. The modern passive house uses a minimalist-yet-elegant brick wall as its facade, with a discreet doorway carved into the front and a simple oriel glass window to peek inside at the stunning interiors. The brick design is modeled after an existing garden wall that connects the property, while the front door mimics the style of an old gate that would have accompanied such a wall in the past.
The original garden and footprint inspired the design of the home, while the historic brick paths leading up to the property were restored as well. The house is certified Passive and includes eco-friendly features such as air source heating, MVHR, solar power, battery storage, super-insulation and triple-glazing in order to sustain over 100% of its required energy.

Past the initial brick and into the interior of the home, a glass roofed courtyard with a winter garden is located in the center, helping to channel natural light to the inside. Natural and repurposed materials, including reclaimed terracotta, sawn oak wood and clay plaster, are found throughout the home in order to connect it with the outdoors. The clients are also avid art collectors, so the designers were sure to include spaces to display and curate their many pieces of pottery and paintings.
The project leaders decided to aim toward passive capability after achieving planning under the open countryside house route. “We’d always aimed to make the house high performing, but having a benchmark to aim for and test against enabled the whole project team to get behind the ambition,” said Fiona McLean of McLean and Quinlan Architects. “The wall panels, 4Wall fromTribus, were an innovative product. A ‘hyperSIP’ panel constructed using steel framing and magnesium oxide boards sandwiching PIR insulation. Their benefits were excellent airtightness, waterproof, minimal thermal bridging, good core strength and low U-Values.”
According to the clients, they’ve become carbon-negative and energy-positive by 40% thanks to the clever design. In the sunny summer months, the house generates 3,500kwh of electricity while only using 60kwh, with remaining power stored in the grid.
