The project was also assessed under BREEAM UK Domestic Refurbishment 2014 achieving a score of 78.85% – ‘Excellent’ at post construction.

Overall, this project goes above and beyond the challenges of a listed property. It is built as a very efficient and healthy environment to live in, saving on tenants’ energy bills and carbon emissions while it operates no different to any other dwellings and cannot be distinguished externally from its neighbors.
