Garage to Bedroom Conversions in South Wales

A garage-to-bedroom conversion adds a proper, heated, ground-floor bedroom to your home for a fraction of the cost of an extension. We handle insulation, walls, flooring, electrics, heating and a new compliant window — meeting all Building Regulations including fire escape requirements. Most projects are completed in 2–3 weeks and require no planning permission.

Benefits

  • Extra Ground-Floor Bedroom: Perfect for elderly relatives, teenagers, or as a quiet guest room.
  • Building Regs Compliant: We meet all fire escape, ventilation and thermal regulations as part of the price.
  • Cheaper Than Extending: Typically 40–60% cheaper than a brick extension of similar size.
  • Adds Property Value: A finished extra bedroom is one of the highest-return home improvements you can make.
  • Fully Insulated: Floor, walls and ceiling fully insulated — warmer than most existing rooms in older homes.
  • No Planning Usually Needed: Almost all garage conversions are permitted development.
