House Extensions in Kingston upon Thames

If you need more space but don’t want the stress of moving, a well-designed extension can completely change how your home works. Albdeco delivers house extensions across Kingston upon Thames, managing the build with a clear plan, tidy working practices, and quality finishes that feel like they’ve always belonged to the property.

What we build

  • Rear extensions (single or double storey), including open-plan kitchen/dining spaces
  • Side return and wraparound extensions to maximise ground-floor space
  • Loft conversions (dormer, hip-to-gable, mansard and rooflight lofts)
  • Structural alterations and reconfiguration (knock-throughs, steels, removed chimney breasts)
  • Roofing works, new windows/doors, insulation upgrades and internal finishes
  • Full refurbishments and upgrades alongside extension works
