The Greenest House offers an alternative to demolition by upgrading and retrofitting existing terraced homes – a typology ubiquitous across UK cities. By increasing the usable space within these homes and converting them into multiple high-quality dwellings, Greenest House delivers affordable, energy-efficient housing while preserving community fabric.

The Greenest House initiative reinvests value unlocked through thoughtful redevelopment directly into the building itself. Upgrades include enhanced insulation, triple glazing, solar panels, and air source heat pumps. This model can reduce a home’s space heating demand by up to 90%, cutting both carbon emissions and energy bills.
