We designed, manufactured and installed the highly insulated timber frame structures to a tight program and exceptionally high-performance standards. Our team were outstanding! Well done to Mikhail Riches and all involved”

It is commended not just as a transformative social housing scheme and eco-development, but a pioneering exemplar for other local authorities to follow.”
