Passivhaus Competition Entry


Our entry for an architectural design competition in Bulgaria for an affordable, low energy family house. We designed the house to Passivhaus standards whilst incorporating features of the local vernacular, such as the irregular window openings, large roof overhangs and materiality.

We were awarded 2nd place and received an honourable mention.

A striking roof overhang on the West elevation exaggerates the concept of a thick element wrapping over the building, also providing solar shading in the afternoon/evening. This concept echoes the form of many buildings in Lozen which feature a stepped façade with large overhangs.
