Kitchen Extensions Beaconsfield

A kitchen extension in Beaconsfield is more often a rear or wraparound addition than a side return, because 61% of homes in the town are semi-detached or detached and only 14% are terraced. That changes the brief from squeezing a side return to deciding how far to go back, how close to the boundary to sit, and whether a bedroom goes on top. We build the footings, the steel into the house, the glazing and the new kitchen as one programme, to the drawings and consent you already hold.

For Beaconsfield, on London-derived ranges a rear kitchen extension of about 30 square metres typically costs £45,000 to £97,500 excluding VAT, or £60,000 to £100,000 for a side return; Buckinghamshire work generally runs below that. GS Renovation Ltd, a building contractor based in Potters Bar, does the work in Beaconsfield: the structural engineer we appoint designs the foundations and steel, we build the room and fit the kitchen, and a registered electrician certifies the electrics.

Where a Beaconsfield kitchen extension can sit on the plot

The plot and its neighbours set the footprint before the kitchen does. With 61% of Beaconsfield homes semi-detached or detached, many plots leave a choice between extending across the back, to the side, or both in an L. A single storey kitchen is not caught by the one metre rule that applies to anything taller. Policy H11 of the South Bucks District Local Plan requires an extension of more than one storey, or any part at or above first floor, to stand at least one metre from either flank boundary.

That one metre matters if you want a bedroom over the new kitchen later. Ask for the ground floor walls to be drawn on the line the upper floor will need, and for the structural engineer to size the foundations for both stages. If the side gap is tight, a single storey side section with a two storey rear section is one way round it. Your designer settles that line; we then set out the footings from the approved drawings and check the boundary position on site before digging.

Housing in Beaconsfield

By the valuation list's count, Beaconsfield holds about 5,390 homes, 77% houses and 23% flats; by age, 10% were built before 1919, 15% between the wars and 76% since 1945. A detached house in Beaconsfield can set its kitchen extension where the garden gets the best light, with the drain run the main limit on the footprint, and 42% of homes here are detached.

Extra care on Penn Road and around Burkes Road

Two parts of Beaconsfield carry a stricter test for extensions. The South Bucks District Local Plan defines Residential Areas of Exceptional Character at Penn Road and across a large area based on Burkes Road and Gregories Road. It describes them as 1930s suburban development with plots over about 2,500 square metres, frontages of about 25 metres and roughly 10 metres between houses. Policy H10 refuses an extension there if it would harm that character, and warns that more than one metre to the boundary may be needed.

For a kitchen that usually means keeping the addition to the rear and keeping the side gaps open. Be aware that the plan left the area between Gregories Road, Furzefield Road and Burkes Road outside the boundary, along with the southern part of Burgess Wood Road South. Check which side of that line your house falls before your designer draws anything. We price the scheme that gains consent, and we build it as drawn, including any reduced width.

Roof form, flank windows and roof lights in Beaconsfield

The roof you choose depends on whether the extension stays single storey. The House Extensions Design Guide attached to the South Bucks District Local Plan says a two storey extension on a house with a pitched roof should carry a pitched roof at the same or a close angle. It also says a flat roof on a two storey extension will usually be unacceptable. That paragraph is written about two storey extensions, so it does not rule out a flat roof with a lantern on a single storey kitchen at the back of a Beaconsfield house.

Flank windows are the other rule to design around. The same guide wants any high level window in a flank wall to have a cill no lower than 1.8 metres above the finished floor inside. On a kitchen that suits a strip of glazing above wall units, which lets light in without overlooking next door. Roof lights and a lantern then bring daylight into the middle of a deep plan. We order glazing only once openings are built and measured.

Footings in Beaconsfield gravel and the inspections that follow

The ground under Beaconsfield varies within short distances, so the trench is inspected before any concrete goes in. The superficial layer mapped across much of the built-up town is the Beaconsfield Gravel Member, recorded by the BGS as 1 to 7 metres of variably sandy and clayey gravel. The council's appraisal adds that, with pockets of clay in the area, residents report soil varying from one garden to the next. Loose gravel sides need support while the trench is open, and clay pockets can deepen the dig.

Buckinghamshire Council's guidance asks for a full plans building control application for any extension beyond a small single storey domestic one. It says a house extension normally needs 5 inspections, and it names foundations, damp proofing, roof structure and drainage among the stages its inspector must see. We programme those visits into the build so no stage is covered up early. Drainage often has to move under the new floor, and that run is laid, tested and seen before the slab goes down.

• Utility rooms and larders at the back of the extension
• New kitchen circuits, with Part P certification from a registered electrician
• Wet underfloor heating laid in the new screed

Trusted Kitchen Extensions in Beaconsfield

A kitchen extension joins two trades that are often split between firms: the builder who opens the back of the house and the fitter who installs the kitchen. We run both in one programme, so the drainage, the electrics first fix and the floor levels are set for the units you have chosen. The steel is sized by the structural engineer we appoint and installed on its padstones, with the house propped, before the wall below it comes out. You get one point of contact and a written programme before work starts.

• One contract for the groundworks, the steel and the kitchen fit
• Free, no-obligation quotations
• Cooker extract taken outside through the new roof or flank wall, not recirculated
