Period property retrofit achieves PassivHaus & BREEAM Outstanding

A retrofitted 1870s century mews house in London has become one of few UK period properties to achieve PassivHaus status.

Located in the Hans Town Conservation Area in Kensington & Chelsea, 126 Pavilion Road was reconfigured and refurbished by Latitude Architects for Cadogan Estates. The scheme also achieved BREEAM Outstanding, a rare feat accomplished in a very small number of domestic refurbishments in the UK.

Hugh Seaborn, CEO of Cadogan, commented:

“126 Pavilion Road has set a new precedent in environmental performance, meeting the demand for an energy-efficient property in a highly desirable location.

“From the outside, the PassivHaus looks no different to its neighbours, retaining the heritage of the area, whilst internally it has been tastefully refurbished and retrofitted with cutting edge energy efficient measures.”

The three-storey house offers over 1,600 ft² of living space and includes contemporary kitchen and dining room, a garage, a ground-floor toilet, a large open-plan living room, a master en-suite bedroom with an office, and a further bedroom and a family bathroom.

While it’s available on the rental market from Cadogan Estates at the staggering £1,795 per week, it is claimed the utility bills would be slashed to just £20 per year thanks to the energy efficiency measures.

Louisa Woodbridge, Head of Residential at Cadogan, said:

“It will be incredibly fuel efficient, with heating bills expected to be as little as £20 for the entire year. In addition to this are the health benefits reported from similar projects – the constant supply of fresh air ensures pollutants and odours are removed from the building whilst maintaining a comfortable indoor air temperature. The high performance insulation and triple glazed windows will also ensure it is extremely peaceful, protected from any noise pollution associated with living in a thriving urban environment”.
