Herne Hill

An extension and refurbishment of an Edwardian semi-detached house in South London, carefully designed to optimise space and flow. A lightness of materials brings freshness and warmth to an inviting family home, while a fabric-first, Passivhaus-inspired approach encompassing triple glazing, whole-house heat recovery ventilation, enhanced airtightness and air source heating reduces energy demands to a minimum. A carefully detailed rear extension and loft conversion provide generous new family spaces, delivering an exemplar in sustainable residential refurbishment on a constrained budget.
