Rainbow Way, Minehead – A Net Zero Carbon Community
Rainbow Way in Minehead, Somerset, is a pioneering residential development delivered in collaboration with Classic Builders and Somerset Council. The scheme provides 54 Net Zero Carbon homes—comprising 33 apartments and 21 houses—designed to LETI standards and setting a benchmark for local authority-led sustainable housing.
Modern Methods of Construction
The project adopts innovative construction techniques to reduce embodied carbon and enhance building performance. External walls are constructed using Pavatherm clay blocks, a breathable, high thermal-performance material with a low carbon footprint. This modern method of construction (MMC) supports rapid delivery while ensuring long-term energy performance and indoor comfort.
Sustainable Technology
Rainbow Way homes are powered by low-energy building systems including air source heat pumps and roof-mounted photovoltaic panels (PVs). These technologies significantly reduce reliance on fossil fuels, lower residents' energy bills, and help the scheme meet its ambitious environmental targets. Collectively, they ensure the development aligns with the broader push towards renewable energy and climate resilience.
LETI Standard
This development is an exemplar of LETI-aligned housing, with a focus on ultra-low operational energy use, high thermal efficiency, and carbon neutrality. The average Fabric Energy Efficiency is 30% above current building regulations, and the homes emit 112% less CO₂ than the maximum permitted by compliance standards. These figures highlight how thoughtful design and technology integration can surpass conventional performance benchmarks.
Building Performance Statistics
Average SAP/EPC rating: 105 (Grade A), outperforming the typical 86/B.
Net energy use: –525 kWh/year on average—homes generate more energy than they consume.
Average CO₂ emissions: –273 kg/year, delivering genuine Net Zero Carbon performance.
Rainbow Way is shortlisted for the Michelmores Residential Project of the Year, reflecting its innovation, collaboration, and exceptional environmental design.
