A deep retrofit to an existing semi-detached home in Brent, London. This bespoke rear extension and full whole house retrofit has been designed to Passivhaus (Enerphit) standards and includes adopting a fabric-first approach as all walls, roofs, and floors have been upgraded with new insulation. The home will incorporate a mechanical ventilation with heat recovery (MVHR) for superior internal comfort, and will be fossil-fuel free (Air source heat pump (ASHP)).

The refurbished homes is due for completion by the end of 2025.
