Verto Homes was twice successful at the UK Property Awards.
The Truro-based sustainable developer won Best Residential Development Cornwall for Island Reach and also Best Developer Website.
Island Reach is claimed to be the first zero carbon smart home development in the UK, and was the first project of its kind for Verto Homes.
Co-founder Richard Pearce said: “It’s our flagship development, and a lot of blood, sweat and tears went into it to make it according to our zero-carbon vision.
“But having stuck to our guns and come out the other side to be awarded the Best Residential Development in Cornwall is really rewarding.”
