The healthy house: the renovation of a dilapidated 1960s box to Passivhaus (EnerPHit) standard

 

Brief:

  • Remodel the existing building fabric, but remain true to the original house.

  • Be certifiable to a recognised Passivhaus standard without compromising on design.

  • Be simple and affordable.

 

Original house:

  • 3-bedroom house built in 1961.

  • Dilapidated, unmodernised and unoccupied for several years.

  • Uninsulated brick/ block cavity wall construction.

  • Demolitions included removal of all internal walls, finishes, fittings and services. 

Completed house:

  • New triple-glazed windows, external doors and roof light.

  • Very high levels of insulation to walls, roofs and floors.

  • Mechanical ventilation system with heat recovery (MVHR).

  • New timber frame studio extension, UK grown cedar cladding.

  • Highly comfortable, clean and fresh environment with constant temperature.

  • Extremely low energy bills.

Occupancy:

  • Noticeably fresher and cleaner.

  • Stable temperature throughout the day.

  • No draughts, damp or condensation.

  • Much improved sleep pattern for the whole family.

  • Significantly less dust, and consequently fewer spiders.

  • Enjoying lovely wide window sills.
