The Brief
A 1993-built detached home in Binfield, RG42 — close to our Bracknell base. The kitchen was at the rear of the house, functional but small, and the separate dining room was used mainly as a homework room. The clients wanted to push the kitchen back by 5 metres, remove the dining room wall, and create one large open-plan family space with bi-fold doors onto new decking. As a local project, this one was managed with particular care. Binfield homeowners considering your extension should know planning permission was straightforward here — see this page's FAQs below for which route applies to your property.
Our Approach
Binfield falls within Bracknell Forest Council's area — a planning authority we work with regularly. The 5m rear extension on a detached property was well within the 6m Neighbour Consultation Scheme limit. No planning application was required. BFC Building Control were notified and the project proceeded quickly through the pre-build phase. The existing dining room wall was loadbearing — structural engineer confirmed a 203x133 UC section RSJ was required.
The Build
Strip foundations at 1.0m to firm sub-soil (London clay prevalent in Binfield). 350mm wide strip with 300mm deep concrete. Drainage run to existing stack extended 5 metres under the new slab. Cavity brick and block — outer leaf in Ibstock Anglian Mixture, inner in Thermalite Turbo. Full-fill Knauf Dritherm 37. The flat roof was framed in 195mm C24 joists, insulated with 150mm Celotex FR5000 (achieving 0.13 W/m²K), topped with a GRP single-ply deck. A single 2000x1000mm fixed rooflight installed centrally. The bi-fold doors: a 3-metre two-panel Origin system in anthracite powder coat. The dining room wall was propped, RSJ installed, props removed. Full first-fix electrics: island pendant positions, under-cabinet circuits, double sockets at 900mm intervals. Gas supply extended to new kitchen position.
Materials & Specification
Facing brick: Ibstock Anglian Mixture. Cavity insulation: Knauf Dritherm 37. Roof insulation: Celotex FR5000 150mm. GRP: laid-up fibreglass roof system. Rooflight: Korniche 2000x1000mm. Bi-fold doors: Origin OB-49, anthracite. RSJ: 203x133 UC section.
The Result
The extension added 20 square metres, and with the dining room wall removed, the combined ground floor space became a 38 square metre open-plan kitchen/dining/family room. The bi-fold doors open to a new composite decking area across the full rear elevation. The rooflight draws light into the centre of the plan. The project finished on programme.

Project FAQs
Do you take on projects in Binfield specifically?
Yes — Binfield is close to our Bracknell base, and we carry out regular work there and across the surrounding Bracknell Forest postcodes.
How does the Neighbour Consultation Scheme work?
For detached homes, the standard permitted development limit for rear extensions is 4m. The Neighbour Consultation Scheme extends this to 8m, provided neighbours within 20m of the extension are notified and given 21 days to object. We manage this process for you — including the council submission and neighbour letters.
What is London clay and how does it affect foundations?
London clay is the predominant soil type across much of Berkshire and Bracknell. It is shrinkable — it expands when wet and contracts when dry. Building Control typically requires deeper foundations in London clay to get below the zone of seasonal movement. On this project we went to 1.0m.
