28 Hensford Gardens, SE26 6JG
This house is a deep low carbon retrofit to classic late twentieth century terrace house typology by the owner architect. Alongside energy demand reduction to EnerPHit criteria and comfort improvement, the house interior has been remodelled
5 minutes walk from Sydenham station.
There is normally space in the cul-de-sac to park.
This is a deep retrofit to a 1960's terrace house, that has been carried out in several steps - the last step is being completed now, so some of the key junctions are still visible. The heating consumption has been measured as each step has been done and had progressively come down. It is now around the Passivhaus EnePhit standard and the owners intend to get it certified. As energy use has fallen so has comfort risen and records of CO2 level, temperature and relative humidity all evidence a very high quality internally.
One of several houses that have had a whole house deep retrofit. Energy efficiency measures include significant insulation (external, internal, floor, cavity and loft), air tightness measures, triple glazed windows, MVHR, and ASHP.
