Woodlands Edge is a development of 30 homes 5 miles outside of Lincoln city centre, designed and built by Gusto Homes who have specialised in eco-housing since 1990.
Woodlands Edge incorporates three different construction methods all designed with a high fabric efficiency and Passivhaus principles in mind, with the performance of each typology monitored through resident feedback. The all-electric homes make use of low carbon technologies including MVHR and PV panels. The 18 units that make up the ‘Edge’ create more energy than they use with both SAP and Environmental Impact ratings over 100.
Community spirit is at the heart of the scheme with each unit having its own allotment, alongside communal facilities including a tennis court and pond.

Woodlands Edge resident:
“I was one of the first residents to move into the Woodlands Edge development and have watched it come to life as more residents have moved in and interacted with the management of the site. It is a different way of living. Making sure we do our part for the planet by moving into an eco-home and altering our lifestyle to reduce our carbon footprint.”
Managing Director, Gusto Group:
“Woodlands Edge is a one-of-a-kind development showcasing the latest eco technology at the time. The site now fully occupied has a great community who are passionate about the environment and are willing to help one another. Each resident has access to a communal store offering various gardening equipment to reduce the need to purchase individual items. One of the aims of the site was to reduce individuals carbon footprint and deliver a showcase development.”
