The L-shaped extension that transforms a terraced house — side return and rear extension combined into one open-plan kitchen-living space. Chartered wrap around extension drawings delivered in seven days and revised free until your council approves.
A wraparound extension combines a side return and a rear extension into one L-shaped addition, wrapping around the back corner of the house. For a typical London terrace it is the single biggest ground-floor transformation available — a full-width kitchen, dining and living space where a cramped galley kitchen and a dead side alley used to be. It is also the extension type councils scrutinise hardest, because it engages every sensitive policy at once: boundary development, neighbour daylight, rear-garden depth and the bulk of the roof seen from surrounding gardens.
Wraparound extension plans almost never qualify as permitted development, because the combined side-and-rear form falls outside the wrap of the permitted development rules — so the drawings have to win a full planning application on their merits. That is exactly what ours are designed to do. We compose the roof so the mass steps down at the boundary, position rooflights to keep neighbouring rooms lit, and hold eaves heights below the thresholds your borough's daylight tests apply. Every decision on the drawing is traceable to a policy in your council's design guidance.
Your pack — existing and proposed floor plans, elevations, sections and site plans — is prepared by chartered professionals, delivered within seven days of survey and revised free until your council issues a decision. Before any of that, a free approval-odds score built from live decision data shows you how wraparounds like yours have fared with your borough's planners.
A fixed process honed on London's hardest extension type — most wrap around extension drawings are submission-ready within seven days of survey.
Enter your postcode and brief. We score your odds against live wraparound decisions in your borough and flag conservation-area or Article 4 constraints before you commit.
We measure the house, the boundaries and the neighbouring windows that will shape the design, then draw accurate existing plans and elevations.
Chartered designers develop the L-shaped plan, roof strategy and glazing to your brief and your council's daylight and amenity guidance.
We submit the full householder application, handle every case-officer query, and revise the drawings free of charge until you have a decision.
Wraparounds attract the most objections and the closest officer scrutiny of any householder extension. Our 96% approval rate is built on drawings that answer those objections before they are made.

Yes — a wraparound extension almost always needs full planning permission, because combining a side and rear extension in one L-shaped structure falls outside permitted development rights. Expect a full householder application if any of the following apply, and assume they will:
One chartered team carries the project from survey to a set your builder can price — and building control can pass.
Existing and proposed floor plans, elevations and sections drawn to your borough's validation checklist, plus site location and block plans.
Hipped, crown-flat or dual-pitch roofs composed so the L-shaped bulk steps politely at the boundary — the detail that decides most wraparound applications.
Eaves, parapets and rooflights positioned to pass the 45-degree tests your council applies to neighbouring habitable-room windows.
Wraparounds remove the whole rear corner of the house. We coordinate the structural calculations for the goalpost steels the open plan demands.
Forms, fees, Planning Portal submission and case-officer negotiation handled end to end — you never chase the council yourself.
Once planning is granted we produce the building regulation drawings — thermal, drainage and structural detail — so work can start without a second design fee cycle.
Every wraparound is shaped by its site, so we price each project individually and guarantee a fixed, no-obligation quote within one working day. The quote covers your complete drawing pack with free revisions until your council approves — no hourly rates, no surprise extras at resubmission.
Most wraparound extension plans are delivered within 7 days of the measured survey. The council then has 8 weeks to determine the householder application. We prepare, submit and manage the whole process, so nothing waits on us — only on the council's statutory clock.
Effectively no. Permitted development treats side and rear extensions as separate classes, and an L-shaped structure combining both falls outside them. A few projects can be phased as two separate permitted developments, but most wraparounds need full planning permission — which is why the drawings matter so much.
There is no fixed limit — it depends on your borough's policies on rear-garden depth, daylight to neighbours and the character of the street. Typical approvals infill the full side return and extend 3m to 4m beyond the original rear wall. Our free approval-odds check shows what your council has recently allowed.
Usually, because it affects neighbours on two sides at once. Objections only matter on material planning grounds — daylight, outlook, overbearing impact — and our drawings are composed to answer those tests in advance. If the case officer still asks for changes, we amend and resubmit free of charge.
Yes. Removing the rear corner of the house requires a steel goalpost frame, and building control will want calculations to prove it. We coordinate structural design alongside your building regulation drawings so the planning-approved scheme is the one your builder actually constructs.
