  • Fully decanted retrofit.
  • Budget of around £65,000.
  • Self-build project. Designed and project managed by myself using friends in trades and other trades already known.
  • Aimed for high levels of insulation and airtightness without specifically aiming for a recognised standard.
  • Mix of pragmatism given the type of dwelling (non traditional so UPVC windows). Also mix of sustainable and modern materials (e.g. wood fibre external/lime render and petrochemical internal insulation).
  • Also a blend of cheap fittings and re use of some of original materials (staircase lived in garden for 3 months) along with splashing out on reclaimed parquet flooring and ash window boards sourced from Treestation. Some minor remodelling of house to add utility/drying room and downstairs toilet.
 

GEEKZONE:

  • Wall U-values < 0.2 W/m2/k
  • Roof < 0.1
  • Floor < 0.12
  • Triple glazing downstairs, reglazed existing upstairs.
  • Airtest 0.75 ACH
  • MVHR
  • Existing 3.3 kW PV array to be diverted to cylinder when not used elsewhere. Lifetime FIT "profits" to pay for approx half of retrofit.
  • Non condensing combi replaced with small system boiler.
  • Underfloor heating installed downstairs.
