Side & Rear Extensions in Weybridge, Surrey & Hampshire
Delmere Projects Ltd designs and builds side and rear extensions across Weybridge and the surrounding Surrey and Hampshire area, including Chobham, Esher, Staines-upon-Thames, Windsor and Woking, covering single-storey and double-storey projects, all quoted in writing before work begins.
A side or rear extension adds new floor space to an existing house, either as a single-storey addition, most often for a larger kitchen or open-plan living space, or a double-storey extension that adds space across two floors at once. Both require proper structural work, including steel beams and foundations sized correctly for the load, rather than just extending the walls and roofline.
Single-storey extensions
A single-storey side or rear extension is most often used to create a larger kitchen, dining or open-plan living space, extending out from the back or side of a property rather than up. Delmere designs and builds these to suit the existing layout, connecting the new space to the rest of the house rather than treating it as a separate room bolted on.
Double-storey extensions
A double-storey extension adds space across two floors in a single project, typically a larger ground-floor living space with an additional bedroom or bathroom above. Building two storeys at once requires more extensive foundations and structural work than a single-storey addition, and Delmere plans the build to keep the rest of the house liveable throughout.
Structural work: steels and foundations
Every extension needs structural calculations to size steel beams and foundations correctly for the load involved, whether that’s removing a supporting wall to create an open-plan space or supporting an additional storey above. Delmere coordinates this structural engineering as part of the build rather than leaving it to be sorted out on site.

Planning Permission and Building Regulations
Some extensions fall under permitted development and don't need full planning permission, while others do, depending on the size, position and the property's planning history. Delmere talks through what's likely to apply during the initial site visit, and handles the planning and building regulations application in-house on some projects, working alongside a client's own architect on others.
Matching the Existing Property
An extension is finished to match the existing brickwork, roofline and window styles wherever that's the brief, so the new space reads as part of the house rather than an obvious add-on. Where a client wants a more contrasting, modern extension instead, Delmere builds to that specification just as readily.
Extensions combined with kitchen or renovation work
A rear extension is often combined with a kitchen renovation or a wider refurbishment, since knocking through to create an open-plan kitchen-diner is one of the most common reasons for extending in the first place. Delmere plans the extension and the renovation together where both are happening on the same project, so the two are budgeted, quoted and built as a single coordinated project rather than two separate jobs.
Why Choose Delmere for Extensions in Weybridge
Extensions involve more risk than most home improvement work, since a poorly sized steel or an underestimated foundation can affect the whole structure of the house. Daniel Cossette has more than 36 years’ experience across extensions, new-builds and structural alterations, and oversees the structural side of every extension Delmere builds.
Delmere Projects Ltd is a family-run, fully insured business based in Weybridge, covering extensions across the surrounding Surrey and Hampshire area. Director Mel Morgan coordinates every project from initial enquiry through to completion, with a detailed written quote agreed before any work begins.
What Happens When You Book an Extension
Getting an extension underway starts with a call or enquiry describing what you have in mind, whether that’s a single-storey kitchen extension or a larger double-storey addition. Delmere carries out a site visit to discuss the scope, talks through what planning permission or building regulations are likely to apply, and arranges the structural calculations needed for steels and foundations.
Once the design and structural details are agreed, you receive a detailed written quote covering the build and any planning or regulations work before anything is booked in. Construction then follows in stages, with a final check to confirm the extension is finished and matched to the rest of the property before the job is signed off.

Cost, planning and what to expect.
It depends on the size, position and the property's planning history; some extensions fall under permitted development and don't need full planning permission. Delmere talks through what's likely to apply during the initial site visit.
A single-storey extension adds space on one level, typically for a kitchen or living area, while a double-storey extension adds space across two floors at once. It needs more extensive foundations and structural work, since it supports an additional floor rather than just a ground-floor room.
