New-build residential properties as part of a major development scheme

For Cornhill Estates Ltd; completed 2006; BREEAM rating Excellent

 

Site B, Upton in Northamptonshire, is a development of 204 homes of 42 different types on seven blocks. Jointly sponsored by The Prince’s Foundation, English Partnerships and Northampton Borough Council, Upton’s strict design brief fully embraces the principles of sustainable construction. Upton, as a whole, will comprise of about 2000 homes, a school, shops, offices and the final phase will be complete in 2010. The overall vision for Upton is that it will become a neighbourhood of mixed housing where a diverse community will evolve. The development aims to become a prime example of national best practice in delivering sustainable neighbourhoods. Block 6 Site B is a traditional street with a mix of contemporary and traditional homes of different sizes and prices.

 

As well as designing some of the buildings on this site, Gale & Snowden Architects worked closely with the other design partners, Prophyrios Associates, the Princes Trust and Cornhill Estates Limited as the ecological design consultants for the site by providing sustainable construction advice and guidance to the team.
