Our project in Herne Hill, South London is well under way - targetting completion later summer. The design extends the existing 1930s house by raising the roof to add new loft space, alongside thermal upgrades incorporating both EWI and IWI, new Air Source Heat Pump and Solar Photovoltaics, MVHR and low energy fittings throughout. In parallel, the garden design by Studio Bristow provides passive shading to the west facing rear facade of the building.
