North Somerset’s first Passivhaus housing development nears completion

25 Sep 2025

Elm Grove in Nailsea is a landmark housing development, delivered through North Somerset Council’s Development Strategy. Homes at the site are now nearing completion, with residents already moving in and more properties available to reserve through shared ownership from Alliance Homes.

Elm Grove, a partnership between housing association Alliance Homes, developer Stonewood Homes, and North Somerset Council, is delivering 52 highly energy-efficient homes, all built to the rigorous Passivhaus standard, on council-owned land. The development is expected to be fully completed by Christmas and all homes will be affordable.

The homes on the site include 26 available for social rent, and 26 offered through shared ownership – a part-buy, part-rent scheme designed to help people onto the housing ladder.

The homes, which offer two, three and four-bedroom houses and bungalows, are designed to significantly reduce energy use and carbon emissions. Features include triple glazing, mechanical ventilation with heat recovery, solar panels, and high levels of insulation, helping residents cut their energy bills by up to 95% compared to the UK average.

Sarah McQuatt, Service Director – New Homes at Alliance Homes, said:

“We’re proud to be delivering these high-quality, energy-efficient homes in Nailsea. Passivhaus certification means our customers will benefit from lower bills and warmer homes, and we’re pleased to be offering these properties as affordable housing for local people.”

The Elm Grove scheme is the first Passivhaus development in North Somerset and one of the few in the South West to offer 100% affordable housing. The project has benefitted from funding support from Homes England and the One Public Estate Land Release Fund for site infrastructure.

James Petherick, Land and Planning Director at Stonewood Homes, said:

“Elm Grove is a flagship for sustainable housing in the region. We’ve worked closely with our partners to create homes that are not only energy-efficient but also spacious, adaptable and built to a high standard. It’s exciting to see the first residents moving in and the community beginning to take shape.”

Councillor Mark Canniford, Executive Member for Placemaking and Economy at North Somerset Council, added:

“This development shows what’s possible when local authorities take a proactive role and work with local partners to facilitate housing delivery. Elm Grove offers much-needed affordable homes for sale and rent, all built to the highest energy efficiency standards.

“North Somerset Council’s Development Strategy looks to deliver homes and jobs that meet the needs our community now and in the future. These are the building blocks of thriving local communities, which is why it’s critical these sustainable Passivhaus homes are affordable and of quality.

“Elm Grove sets the tone for what can be achieved when we work in partnership, ensuring development on council land can help local people unlock opportunities over many years to come.”
