The prestigious gold award for Best Development, a fiercely contested category, went to Lower Mill Estate at the What House? Awards 2011, while Berkeley Homes picked up silver and One Housing Group secured bronze.
Lower Mill Estate's owner Jeremy Paxton and son Red collected the gold award for Best Development last November for Somerford Keynes, a strikingly innovative and adventurous estate near Cirencester in Gloucestershire.
Described as a "remarkable tale of ecological enterprise and architectural boldness" by editorial director of whathouse.co.uk, Rupert Bates, the development features a community of holiday homes, not primary residences, and led by nature, with designs from world-renowned architects.
The scheme also encompasses a nature reserve of European significance, two Sites of Special Scientific Interest and an infinite variety of wildlife, with more than 3,000 species at Lower Mill.
"We annually audit everything that wiggles and moves on the estate and update our biodiversity plan," said Jeremy Paxton.
He added: "Lower Mill is an equation of ecology, architecture and people, making for a responsible community."
Lower Mill, which has an impressive 48 different architectural house types, will feature 575 homes in total, with prices ranging from £295,000 to £3m,
The Berkeley Group scooped 12 awards at the prestigious What House? Awards 2011, including silver in this category which highlighted The Royal Arsenal Riverside in Woolwich as an example of "best practice in the regeneration of listed buildings".
Royal Arsenal Riverside is one of South East London's most exciting riverside addresses. Occupying a prime location along the River Thames, the development enjoys a rich history and is being developed into a sustainable and vibrant new community. Prices start at £252,500.
Established in 1976, The Berkeley Group has transformed itself from a traditional housebuilder, into a pioneering urban regeneration business with new home developments delivered through its divisions which include Berkeley Homes, St George, St James Homes and St Edward Homes.
"The Berkeley Group is one of the UK's best new home developers. Having earned themselves a first-class reputation for building top quality new homes across London and the Home Counties constructing lavish houses to top quality apartments, they aspire to cater to all buyer needs," said Rupert Bates.
Roden Court, One Housing Group's flagship scheme in Highgate, north London, deservedly won the bronze award in the Best Development category. The company has redeveloped the site at Roden Court to provide 136 high quality affordable homes.
Alan Williams, Development Director at One Housing Group, said: "This scheme is the result of a thorough consultation process with residents, local stakeholders and partners. We are delighted to receive this award in recognition of the contribution that Roden Court has made to meeting the need for affordable housing in the borough. The scheme is already bringing huge benefit to the area by encouraging a balanced, sustainable community."
