Wraparound Extension Drawings in West Kensington W14
Fixed-fee, MCIAT-chartered wraparound extension drawings for West Kensington (W14) homeowners — London Borough of Hammersmith & Fulham validation and local constraints handled from the start.
West Kensington (W14) is defined by its red-brick Victorian mansion flats — the Gunter family developed much of the district as planned mansion-block and terrace streets, and a large share of the housing is now flats rather than whole houses. That tenure shapes every project: rear, roof and party-wall work here typically touches more than one household.
The Gunter Estate, Barons Court and Sinclair Road conservation areas cover much of the district and protect that planned red-brick character. We establish the conservation boundary, the tenure and the block's shared elements before recommending a route, and draw to the borough's guidance.
Planning in West Kensington (W14): what to know before you apply
W14 sits across the Gunter Estate, Barons Court and Sinclair Road conservation areas, which protect the planned red-brick mansion-flat streets and remove permitted development rights on many of them — and because so much of the stock is flatted, extensions and loft work are assessed against shared roofs, rear elevations and party walls as well as conservation character. London Borough of Hammersmith and Fulham does not publish an Article 4 schedule to the national open-data register, so an empty entry there is not evidence of absence — we confirm the current directions with the council before advising.
Typical West Kensington housing stock

Wraparound Extension Drawings for West Kensington (W14) homes: the package and the process
Every wraparound extension drawings we prepare for an West Kensington property is drawn to London Borough of Hammersmith & Fulham’s validation standards and tuned to the W14 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 |
