Delivering net zero homes for Be First London

Collida are pleased to be working alongside Willmott Dixon to deliver eight net zero apartments as part of the £134m Phase 2 regeneration of the Gascoigne Estate in Barking and Dagenham for Be First.


Block F2 of Gascoigne Project explained:

Due to be completed in Spring 2023, Block F2 is a pioneering project comprising a four storey apartment building housing eight net zero apartments nestled within a borough-wide regeneration project – set across 400 hectares of land – which will include the delivery of up to 50,000 high-quality new homes and create 20,000 new jobs by 2037.

The development provides homes that help address fuel poverty and leave a minimal environmental impact across their lifetime. The use of Collida’s housing solution aligning fast, efficient delivery though modern methods of construction (MMC) with exemplar building performance. With the Passivhaus standard delivering energy performance in excess of current building regulations and even the 2025 Future Homes Standard, Collida’s approach eliminates the need for costly future retrofit, whilst ensuring heating and energy bills to tenants cost less than £2 per day.

Some key numbers about a Collida Living home:


Developed with a fabric-first approach through the Passivhaus standard


No expensive retrofitting required as future-proofed against both current and planned legislation


Years design lifespan


Lower embodied carbon than LETI (business as usual) benchmarks


Less labour used compared to conventional construction to deliver earlier occupation


Low energy bills – approximately just £2 a day

Challenges conquered:

The biggest challenge faced on the Block F2 project was the use of Collida’s living system to update an existing planning approved design to deliver net zero with integrity.

The building, as originally designed and approved, was based on Part L 2018 building regulations. Collida supported Be First and Willmott Dixon to adapt this existing design in line with Passivhaus principles to ensure they meet current and future sustainability standards – providing developers and homeowners with reliable, energy efficient homes.

Collida’s approach centred around a super-insulated envelope to reduce fabric heat loss and primary energy demand, aligned with multi-stage testing of air permeability in support of a target air tightness twenty times better than the Future Homes Standard. To deliver this we have partnered with leading offsite manufacturers to achieve greater than 70% pre-manufactured value – all delivered using scalable technologies supported by both BOPAS and NHBC

When we were brought on the designs were already planning approved however through our Collida Living system, we were able to tactically redesign it to maintain the existing design intent but upgrade the building’s performance to meet the Passivhaus standards. The project now  creates a building that meets current and future net zero carbon targets
