Justin Bere is a British architect based in London. He is founder of his own practice bere:architects and has developed a specialism in low energy passive house. Bere Architects’ retrofit stretched its tiny budget, winning funding for being the first non-domestic London Passivhaus. They ran a competition, and Justin Bere Architects won. Their proposal The chosen site pushed the Passivhaus idea to its limits. 1,ft up at.

Living in a large cold farmhouse, the owners needed little persuading of the merits of aiming for Passivhaus when building a guest house on their land. Lark Rise is an all-electric, two-bedroom guest house designed to Passivhaus Plusproducing at least arcihtects as much energy in a year as it requires, while maintaining a very high level of comfort all year round.
This new Passivhaus category supports a future scenario of a world where solely renewable energy sources are used, and to enable occupants to archhitects as renewable energy prosumers, rather than just consumers. It was completed back in October and has been monitored for two years post occupancy.
Passivhaus or Passive House?
It was recently certified in November The main challenge was the planning requirement to maintain the openness of architetcs site, which meant cutting the house into the slope of the land and partly burying it to keep its profile as low as possible. The client had strong ideas about the design bsre the house and to maintain the integrity of the vision, and the visual alignment of certain components, the architects had to rely on ultra-thin vacuum insulation in several areas.
As such, Lark Rise demonstrates the potential for the UK government to drive policy initiatives that will save money that will otherwise be required for power stations to supply the alternative business-led scenario. Gentle nudging of market forces can provide a new focus for UK industry to facilitate a joined-up plan to enable the emerging microgrid vision to materialise smoothly — in short, to provide the paassivhaus needed to create a new Passuvhaus Technology Revolution.
This will be carried forward in our future work. Justin Bere, Director, bere: The building has a concrete basement substructure with timber frame superstructure.

The prominant glazed north-west facade proves that a Passivhaus development need not consist of rows of south-facing homes, but can be planned according to the social or other requirements of a site.
