- Reds10 is regenerating a disused former library site into three high quality residential blocks, overcoming utilities constraints, environmental complexities, and a sensitive planning history.
- All 11 homes achieve EPC A, supported by ASHPs, PV arrays, battery storage and a fabric first design for ultra low running costs.
- A high PMV (80–85%) modular solution enables a rapid programme from February start on site to December handover, ensuring compliance with funding requirements.
Reds10 is delivering 11 new affordable family homes for Raven Housing Trust on a brownfield regeneration site in Merstham, transforming a derelict former library into a modern, energy efficient residential development.
Designed for shared ownership, all homes meet NDSS and M4(2) accessibility standards and are delivered using Reds10’s high pre manufactured value (PMV 80–85%) modular construction approach. This ensures predictable quality, rapid delivery, and minimal disruption to the surrounding community.
Reds10 is providing a complete turnkey solution, covering design development, planning, demolition, utilities, manufacturing, installation, and landscaping. The development consists of three blocks of family homes, each designed to deliver exceptional comfort, sustainability, and long term operational performance.
DELIVERING MODERN, ENERGY EFFICIENT FAMILY HOMES
The scheme includes a mix of 2 bed and 3 bed homes, designed to provide flexible, high quality living spaces for families.
Home Mix:
- 4 × 2 bed, 2 storey homes (83.7m²)
- 7 × 3 bed, 2 storey homes (94.2m²)
- Total GIA: 994.2m²
All homes are designed to support comfortable, sustainable living, with modern layouts, high thermal performance and abundant natural light thanks to a stringent fabric first approach.
DESIGN AND LAYOUT HIGHLIGHTS
Internal Spaces
- Generous NDSS compliant layouts
- M4(2) accessibility features for inclusive design
- High efficiency building envelope for improved comfort and reduced energy use
- Contemporary family focused interior fit out across all homes
External Environment
- Full soft and hard landscaping
- Enhanced public realm and ecological features
- Utilities diversions and new service connections as part of the turnkey package
- 10% Biodiversity Net Gain delivered onsite
SUSTAINABILITY AT THE HEART OF THE BUILD
The Merstham development sets a strong benchmark for small site modular housing, delivering outstanding sustainability performance and long term operational savings.
Key sustainability features:
- Operational Net Zero – EPC A
- Air Source Heat Pumps
- Roof mounted PV arrays
- Dedicated battery storage for on site energy optimisation
- EV charging points
- High airtightness and thermal performance through a fabric first approach
- Reduced embodied carbon through offsite manufacturing
Together, these measures significantly reduce running costs for future residents and support Raven Housing Trust’s environmental ambitions.
OVERCOMING CHALLENGES FOR FAST TRACK DELIVERY
The site presented several constraints requiring careful coordination and proactive stakeholder engagement:
- Tight, constrained site with significant existing utilities
- Environmental management, including the safe relocation of bats
- Complex planning history, with a previously refused application later granted on appeal
- Sensitive community engagement to address local concerns
- Funding and programme pressures linked to Homes England requirements
Reds10’s integrated turnkey model enabled rapid progress from design to planning to factory production, with start on site in February 2026, factory manufacturing in June 2026, and handover scheduled for December 2026.
IMPACT & INNOVATION
This development exemplifies how modular construction can transform small, challenging brownfield sites into high quality, sustainable, affordable homes. By integrating precision manufacturing, renewable energy systems, and a strong focus on community engagement, the Merstham project supports Raven Housing Trust in delivering modern shared ownership homes that are affordable to buy, efficient to run, and built for long-term resilience.
