Wraparound Extension Drawings in Maida Vale W9
Fixed-fee, MCIAT-chartered wraparound extension drawings for Maida Vale (W9) homeowners — Westminster City Council validation and local constraints handled from the start.
Maida Vale (W9) in Westminster is defined by two building types: red-brick Edwardian mansion blocks along Elgin and Sutherland Avenues, and wide late-Victorian stucco villas on the streets around them. The Maida Vale conservation area covers them both, and the protected feature is the uniformity — the repeated frontage and the unbroken roofline down a whole avenue.
That uniformity is why roof and front-elevation work is the hardest thing to get through here, and why most W9 projects are internal reconfigurations or rear work instead. Westminster's Article 4 direction removes permitted development rights for basement development, so a lower-ground excavation needs a full planning application from the outset. The more common constraint is simply tenure: the great majority of W9 stock is flats within those mansion blocks, and flats have no permitted development rights in any case, so freeholder consent runs alongside planning whatever the designation says. We confirm tenure and the Article 4 position before drawing to Westminster's guidance.
Planning in Maida Vale (W9): what to know before you apply
W9 sits within the Maida Vale conservation area, which protects the uniform frontages and rooflines of the Edwardian mansion blocks and late-Victorian stucco villas — making roof and front-elevation changes the most sensitive work here. Westminster's Article 4 direction removes permitted development rights for basement development, so lower-ground excavation needs a full planning application. Most of the district's stock is mansion-block flats, which have no permitted development rights regardless of designation and need freeholder consent alongside the application.
Typical Maida Vale housing stock
Red-brick Edwardian mansion blocks along the main avenues and wide late-Victorian stucco villas on the side streets, the great majority held as flats rather than whole houses.

Wraparound Extension Drawings for Maida Vale (W9) homes: the package and the process
Every wraparound extension drawings we prepare for an Maida Vale property is drawn to Westminster City Council’s validation standards and tuned to the W9 constraints above. Here is what the drawing package covers and how the process runs from first survey to approval.
A wraparound extension is what happens when a rear extension and a side return are designed together rather than as two separate projects: the new build wraps around the back corner of the house, turning a galley kitchen and a small rear room into one continuous kitchen, dining and living space running the full width of the plot. It is the most ambitious single-storey option most London terraces and semi-detached houses have, and because it reshapes almost the entire ground floor, it needs careful structural and drainage planning as well as a confident planning application.
DrawingsDirect draws wraparound extensions for full planning and building regulations, with structural calculations for the L-shaped frame and any drainage diversion produced in-house by our MCIAT-chartered team, on a fixed fee. If your project is a single-storey rear addition or a side infill on its own, see our Rear Extension and Side Return Extension pages; if you also want a second storey, see Double Storey Extension Drawings.
What makes a wraparound extension different from a rear or side return alone?
A rear extension adds depth at the back of the house; a side return adds width down the alley; a wraparound does both at once, so the new floor area turns the corner of the original building rather than sitting against just one wall. The result is typically the largest open-plan space a single-storey extension can deliver, but it also means more of the original external wall is removed and more of the roof is new, which raises the structural and drainage stakes compared with either extension on its own. Homeowners who start out planning a rear extension or a side return alone often move to a wraparound once they see how little extra it costs to combine the two, since much of the groundwork, roof structure and glazing is shared between them rather than duplicated.
Do wraparound extensions need full planning permission in London?
Almost always, yes. Permitted development allowances are calculated on combined additions to the original house, and a wraparound's depth plus width together generally exceed the volume and footprint limits that apply to a rear extension or side extension considered separately. A Lawful Development Certificate route is rarely viable for a genuine wraparound.
Conservation area status and Article 4 directions, common across the terraced streets where wraparound extensions are most popular, remove permitted development rights further still, so we design every wraparound on the assumption it will go through full householder planning.
| Route | What it covers | Typical fee |
|---|---|---|
| Full planning permission | Required for almost all wraparound extensions given the combined footprint | Full Planning pack ~£1,600–£2,400 |
| Planning + Building Regulations (structural) | Combined pack including structural calculations for the L-shaped frame and drainage diversion | Planning + Building Regs pack ~£2,200–£3,850 |
| Rear extension alone (comparison) | Smaller single-storey addition, may qualify for permitted development | see Rear Extension Drawings, from £1,100 |
| Side return alone (comparison) | Widens the kitchen only, keeps garden depth unchanged | see Side Return Extension Drawings, from £1,400 |
