Dolphin Square Restoration

: London

Dolphin Square is an exemplary restoration project integrating sustainable design practices into the heart of a historic estate. Originally built in the 1930s, the estate has undergone an ambitious retrofit to meet modern sustainability standards while preserving architectural heritage.

The primary sustainability goal for the project was to reduce energy demand and carbon emissions, while improving the environmental performance of the estate. To achieve this, over 2,000 heritage-style double-glazed windows were installed in Phase 1, as well as 50 air source heat pumps, replacing outdated gas systems with low-carbon alternatives. Additionally, 100 solar panels were installed on rooftops to generate renewable energy for communal spaces. By completion, the project will have added 400 solar panels, 150 heat pumps, and installed over 6,000 windows. The project is also focused on circular economy principles. Existing structural elements, including brickwork and concrete frames, were retained to minimise embodied carbon, while new interior modular strategies were designed for long-term sustainability and reduced waste. Furniture, appliances, and fittings removed during the refurbishment were donated to over 500 local households, promoting reuse and reducing waste. Dolphin Square is working towards achieving a 95% reduction in operational carbon emissions and an 80% reduction in energy demand across the refurbished blocks by completion. The project is also targeting BREEAM In-Use and WELL certifications, ensuring ongoing accountability and performance monitoring. By meeting ambitious sustainability targets, Dolphin Square showcases how heritage buildings can be retrofitted to achieve environmental excellence, setting a new benchmark for sustainable urban living.
