Wraparound Extension Drawings in Enfield EN1
Fixed-fee, MCIAT-chartered wraparound extension drawings for Enfield (EN1) homeowners — London Borough of Enfield validation and local constraints handled from the start.
Enfield Town (EN1) is the historic heart of the London Borough of Enfield, running from the Georgian and Victorian buildings around Market Place and Church Street south through the Edwardian villas of Bush Hill Park to the interwar semis around Southbury.
Two conservation areas dominate the outcode — Enfield Town, protecting the market-town core, and Bush Hill Park, a planned estate of 1880s-1900s houses designated in 1986 — so extensions and elevation changes are judged against a well-defined local character.


Planning in Enfield (EN1): what to know before you apply
Much of EN1 sits within either the Enfield Town or Bush Hill Park conservation area, so permitted development cannot be assumed and the borough's 2003 Article 4(1) direction removes rights to alter windows, doors, roofs and front elevations without consent. We confirm a property's conservation and listing status before drawing and prepare the application to Enfield's validation and design guidance.
Typical Enfield housing stock
Georgian and early-Victorian houses around Market Place and Church Street in the historic market town, the planned Edwardian suburb of Bush Hill Park (designated 1986) with its Arts and Crafts and Baroque-revival villas built from the 1880s, and interwar semis filling the streets between.

Wraparound Extension Drawings for Enfield (EN1) homes: the package and the process
Every wraparound extension drawings we prepare for an Enfield property is drawn to London Borough of Enfield’s validation standards and tuned to the EN1 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 |
