Wraparound Extension Drawings in Ealing Broadway W5
Fixed-fee, MCIAT-chartered wraparound extension drawings for Ealing Broadway (W5) homeowners — London Borough of Ealing validation and local constraints handled from the start.
Ealing Broadway (W5) is the heart of 'Queen of the Suburbs' Ealing, and the housing reflects it — substantial Victorian and Edwardian villas climbing the hill north of the Broadway, with mansion flats and larger subdivided houses nearer the station. The scale of these plots means loft conversions, rear extensions and outbuildings are common, but so is the conservation-area control that shapes them.
Three conservation areas meet across the district: Mount Park on the higher ground to the north, Ealing Common to the east and Ealing Green to the south. Which one a property falls in changes what is achievable on the roof and front elevation, so we establish the boundary and the borough's guidance before recommending a permitted-development or full-application route.


Planning in Ealing Broadway (W5): what to know before you apply
W5 carries no borough-wide Article 4 direction affecting typical householder work, so many Ealing Broadway houses retain permitted development rights for rear and loft projects — but the Mount Park, Ealing Common and Ealing Green conservation areas are the significant exceptions, and the generous villa plots mean extensions are judged closely against neighbouring building and garden lines. London Borough of Ealing does not publish an Article 4 schedule to the national open-data register, so we verify the current position with the council before advising.
Typical Ealing Broadway housing stock
Large late-Victorian and Edwardian villas and semi-detached houses on the hill north of the Broadway, many on generous plots, alongside Edwardian mansion flats and subdivided family houses closer to the station.

Wraparound Extension Drawings for Ealing Broadway (W5) homes: the package and the process
Every wraparound extension drawings we prepare for an Ealing Broadway property is drawn to London Borough of Ealing’s validation standards and tuned to the W5 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 |
