Extensions

House extensions in North and West London.

Side, rear and wrap-around extensions built by a small, experienced team. Kourosh Mafi visits, quotes and runs the job himself, from the foundations to the final finish.

What we build

  • Single-storey rear extensions
  • Side return and wrap-around extensions
  • Knocking through to open-plan kitchens and living areas
  • Structural alterations, with steelwork fitted to your engineer's design
  • Roofs, rooflights, insulation and everything needed to finish the room

How an extension job runs

Visit and quote. Kourosh comes to the property, looks at the existing building and talks through what you want. You get a written quotation for the agreed work.

Drawings and approvals. If you need plans, planning permission or Building Regulations approval, we work alongside your architect and structural engineer.

The build. Foundations, blockwork, steel, roof, windows and doors, plastering, kitchen, flooring and decorating. We plan and coordinate the trades, with plumbing and electrical work brought in as needed.

One point of contact. You deal with Kourosh from start to finish.
