Ashmere, a development by Vistry Kent and Clarion in Ebbsfleet Garden City, picked up two Housing Design Awards.
Homes England chose it as the best example of a scheme built to Building for a Healthy Life principles.
Future Homes Hub, a Government and industry partnership, also selected Ashmere as the standout project for net zero communities.
Both awards highlighted the quality of Ashmere’s streets and spaces, its focus on the community and its sustainable placemaking.
David Birkbeck, CEO of Design for Homes, said: “There are few large developments where you can feel the human focus.
“And there are even fewer that win Housing Design Awards, two in this case.
“Ebbsfleet needed better placemaking and now Vistry has delivered the quality it wanted.”
Ashmere currently has 281 homes, with both private and affordable tenures. It forms part of a wider plan for 3,000 homes, schools, shops, green spaces and sustainable transport links. The scheme draws on the UK’s garden city heritage and aims to reflect local character and the environment.
The site, delivered under the Countryside Homes brand, was noted for its design inspired by local chalk cliffs, farmland and nearby Kent villages.
Judges pointed out the pedestrian-friendly layout, biodiverse landscapes and the addition of community amenities and open spaces.
Ashmere was built to Building for a Healthy Life principles, a national framework for healthy, green and inclusive neighbourhoods.
The awards recognised Vistry’s approach to wellbeing and sustainability.
Chris Foot, associate development director for Vistry Kent, said: “This recognition reflects the hard work and vision of everyone involved in Ashmere.
“It’s a shining example of how thoughtful design can shape communities where people truly love to live.”
