Westlea Integer Homes

A pilot development by a social landlord of two family houses. The project demonstrates a high level of sustainability and incorporates a number of 'green' features including a wide range of reclaimed and recycled materials.

The development was intended to demonstrate what is possible rather than provide a model for new development. It is recognised that not all features would be economically viable.
