Before / After: rehabilitation examples

See how to transform an old interior (house, apartment, loft) into a bright living space: diagnostics, works, materials, architect tips, indicative budgets and pro advice.

Before / after examples (house, apartment, loft)

Every rehabilitation is a unique project: floor area, initial condition, load-bearing walls, ceiling, building constraints, roof, possible extensions, choice of materials, and target room style (kitchen, bedroom, living room). Here are three concrete cases—from a Paris flat to a stone house, up to a glazed loft.

Tip: shoot before & after photos (a short report) to track the site and boost resale price.

Key steps for a successful renovation

Survey & initial condition

Check the building structure, walls, ceiling, roof, electrics and ventilation. An architect or project manager can frame the project.

Plan & style

Define volume, openings, room layout (kitchen, bedroom, living), materials (wood, glass, stone), and the ambiance (bright, industrial, character).

Works & monitoring

Selective demolition, façade repair, insulation, floors (parquet), partitions, paint. Site monitoring and quality control up to handover.

Practical advice & winning styles

  • Openings & light: glazed glass partitions, large glass doors, mirrors to amplify light.
  • Materials: mix wood + stone + metal for a contemporary character; parquet for comfort.
  • Spaces: create a through living space, re-distribute room by room, work the volumes.
  • Outdoors: think façade, terrace, garden if outdoor space exists.
  • Owners & families: anticipate future use of the home and storage (basement, attic).
