This project upgrades the environmental performance of a Victorian villa and proposes a modest rear extension with a small paved area outside wrapped by the garden. The proposed extension’s flat roof keeps the mass low and adds to the nestled nature of the lower ground room into the land. The sinuous terrace is cut into the earth, providing space for external dining and an allocated external store for housing an air source heat pump as part of the house’s thermal upgrade strategy, concealed via timber louvres.
The introduction of Solar Slates to the main roof offer a forecast energy production of 5.5kw, is an obvious benefit to reducing energy reliability from non-renewable technologies. Solar Slates simulate natural blue/grey slates very well, having the added aesthetic benefit compared to solar panels.
