A 1930s house in Coppet, upper floor renovated

The upper floor of a 1934 house renovated while the family lived downstairs: internal insulation, electrics, bathroom and parquet floors.

Room with white cornices, a bay window and pale parquet House
Upstairs bathroom with a glazed level-access shower Coppet

The starting point

The owners wanted a comfortable, better insulated upper floor without moving out, with a grant application filed before the works.

What we did

  • Staircase closed off with a dust screen, site access from outside.
  • Buildings Programme application filed by the owners before the start, using our description of works.
  • Original cornices and doors removed, restored and refitted.
