Wraparound Extension Drawings in Addiscombe CR0
Fixed-fee, MCIAT-chartered wraparound extension drawings for Addiscombe (CR0) homeowners — Croydon Council validation and local constraints handled from the start.
Addiscombe in CR0 sits just east of central Croydon and blends Victorian and Edwardian terraces with interwar semis on generous suburban plots. It is very much a family-extension neighbourhood, so most of our work is rear and side extensions, loft conversions and garage conversions that add practical space for growing households.
Away from the East India Estate conservation area, much of Addiscombe is comparatively permitted-development friendly, which can open up straightforward routes to more space. Where conservation control or a larger scheme applies, we prepare full planning drawings that address Croydon's amenity, scale and materials tests so the application is assessed on solid ground.
Planning in Addiscombe (CR0): what to know before you apply
There is no published householder Article 4 direction we depend on for Addiscombe, and much of the suburb benefits from permitted-development rights for modest extensions and lofts. The main exception is the East India Estate conservation area, where frontage, roof and material changes are more tightly controlled; elsewhere neighbour amenity and extension depth are the key limits.
Typical Addiscombe housing stock
Addiscombe, east of central Croydon, mixes Victorian and Edwardian bay-fronted terraces with interwar semi-detached housing along its residential streets. It is a strong family-extension market, so the common projects are rear and side extensions, loft conversions and garage-to-room conversions that add space without the tight constraints of inner London.

Wraparound Extension Drawings for Addiscombe (CR0) homes: the package and the process
Every wraparound extension drawings we prepare for an Addiscombe property is drawn to Croydon Council’s validation standards and tuned to the CR0 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 |
