This regeneration project involves the masterplanning, design and construction of a 1930s Peabody estate in St. John’s Hill, Clapham Junction.

Focusing on creating a compact and interconnected central living spaces, 597 homes have been designed for the private and social housing market. This includes new community facilities, retail and underground car parks.

Being constructed over three phases, we worked closely with Hawkins Brown to design an energy strategy to exceed the targets set by Wandsworth Council and the GLA Energy Team. A centralised energy centre incorporating combined heat and power (CHP) generates heat for the entire masterplan, distributed through a district heating network. The district heating has been designed to minimise distribution losses, while the CHP has been sized for economic viability.

A significant proportion of electrical demand was supplied by a large array of roof mounted photovoltaic panels. Our work included strategic and detailed design advice for MEP, acoustics and sustainability. All the homes have been designed to achieve Code for Sustainable Homes level 4, while the commercial spaces meet BREEAM Excellent standard. The site is located adjacent to busiest railway line in Europe, with over 2000 trains passing each day causing very high levels of noise and vibration.

A key challenge for our acoustic team was to deliver acoustic comfort within the homes located adjacent to the railway. Following extensive noise and vibration surveys, Max Fordham established the enhanced requirements for both façade performance and building vibration isolation to meet the stringent planning requirements. They also worked closely with the MEP team to design an acoustically attenuated natural ventilation solution which allows residents to benefit from free cooling while reducing external noise intrusion.

The first phase including 153 homes, underground carpark and central energy centre was completed in 2016, with the later phases to follow.
