Award RIBA London Award 2025

The award winner tells us: "Pine Heath is an extensive whole house renovation and sensitive energy focused transformation of a modernist townhouse set in the Hampstead Conservation Area, originally designed by Ted Levy, Benjamin, and Partners in the late 1960s.

Every element of the house was addressed and considered in detail, from reconfiguring layouts and creating bespoke interiors, to upgrading the external envelope and implementing a renewable-energy strategy. The scheme exemplifies Studio Hagen Hall’s approach to enhancing and respecting post-war residential architecture; prioritising a rich dialogue between the existing character and contemporary interventions."

The jury says: "With one of the clients being professionally involved in the energy industry, and together looking to create a long-term home for their young family, sustainability was rigorously considered from the outset. Critical elements of the thermal envelope, such as windows, uninsulated walls and floors, and the roof, have been discreetly either replaced or enhanced. Vacuum glazing was chosen to minimise heat loss through the bespoke replacement windows. Roof-mounted photovoltaic panels connected to an air-source heat pump on the uppermost terrace replace the previous gas boiler."
