What House Extensions in Downe Involves

The process starts with a site visit to discuss your goals, budget and the practical constraints of your plot. From there we help develop workable designs and advise on planning permission and building regulations before any work begins. Once the plan is agreed, Wayne leads the groundworks and structural brickwork, with vetted subcontractors brought in for plumbing, electrics and finishing, and a final walk-through confirms every detail before handover.

We build the full range of extension types: single and double storey extensions, side returns, rear extensions and wrap-around extensions that combine a side and rear build into one open-plan space. Wrap-arounds in particular tend to deliver more usable floor area than a rear extension alone and work well on the terraced and semi-detached homes common across the area.
