Rear extensions are often the most efficient way to unlock better living space, but success depends on proportion, light, structure, and how the extension connects back into the original rooms.

We design rear extensions around the way clients actually use the property, whether that means a larger kitchen-diner, a family room, a garden-facing lounge, or a more flexible open-plan ground floor.

Early planning around drainage, neighbouring boundaries, glazing strategy, and garden levels helps avoid the common issues that cause delays or compromise the finished layout.

For rear extension in Castelnau, the brief is usually shaped by Whether rear, side, or wraparound gives the best layout gain for the budget., How much of the project value comes from shell space versus the interior fit-out., and Whether the household can remain in occupation once structural openings and kitchen works begin.. That is why we scope the work around edwardian house conditions in Barnes instead of relying on a one-size-fits-all trade description.

Before fixing specification and budget, we review Permitted development limits, conservation context, and neighbour boundaries should be checked early. and Structural engineering, drainage design, and party wall coordination often affect the build route.. We then price around the issues that genuinely move the job, such as Structural openings, foundations, and steelwork complexity. and Rooflights, glazing packages, and kitchen or utility fit-out level..

Where we have supporting evidence, we anchor the page to nearby related case study so the guidance reflects real delivery signals rather than filler copy. That matters in Castelnau, where recurring concerns include Large plots allow ambitious extension and renovation projects, Hammersmith Bridge closures have historically affected access — plan deliveries carefully, and Mature garden trees often have TPOs requiring arboricultural reports.
