Lancaster Cohousing is currently the largest completed Passivhaus housing development in the UK, and also meets Code for Sustainable Homes Level 6 and Lifetime Homes, with site-wide renewable energy systems, all at affordable costs.
This owner-occupied project evolved through a participatory design process with the individual householders and Eco Arc Architects. It follows the cohousing model with 41 private houses in a car-free site, alongside shared community facilities including a common house, laundry, orchard, gardens, children’s room and play areas, and on-site work spaces for rent. The result is a neighbourhood based upon ecological values, where, as interviews with the residents have shown, it is very easy to live a low carbon, sustainable lifestyle in comfort.
