Passivhaus, Eldorado Crescent

Small windows to the north minimise heat loss, whilst extensive glazing to the south give plenty of solar gain (with overhanging eaves and PV panels to prevent overheating).

The design of the replacement dwelling is very much a response to its surroundings. Red brick picks up on the same material in the surrounding Victorian houses. The roof eaves are deliberately overhanging in the same manner as on surrounding buildings, and the roof pitch and ridge height reflects those of the surrounding houses.

Pulling the angle of the ground floor rear elevation further out of parallel from the street line than the first floor allows the photovoltaic panels to be facing almost due south.
