Located in Burnham Overy Staithe, in Norfolk, United Kingdom, these Passivhaus units consist of a terrace of three dwellings, forming part of a mixed development of affordable and open market housing reflecting the local vernacular of traditional fisherman's cottages.
The use of flint, local red brick and clay pantiles help the buildings assimilate into the landscape and gives them a friendly, familiar appeal. The traditional deep reveals and smaller north facing windows required for the Passivhaus standard naturally reflect what our forebears understood about shelter and consequently the scheme had little difficulty in delivering this most modern standard within a traditional context.
The units are all designed as 2 bedroom houses at 77 m²; in addition to delivering remarkable operational energy, the building also received a Code for Sustainable Homes level 4 rating.
The houses are heated utilising a compact combination unit (no gas available), which also provides domestic hot water. Early monitoring indicates performance as anticipated with heat load hovering around 8 W/ m² to deliver a constant 21 degrees, internal air quality averaging 650 ppm and relative humidity averaging 55%.
