Wraparound Extension Drawings in Chadwell Heath RM6
Fixed-fee, MCIAT-chartered wraparound extension drawings for Chadwell Heath (RM6) homeowners — London Borough of Barking and Dagenham validation and local constraints handled from the start.
Chadwell Heath (RM6) is an interwar arterial suburb strung along the old Roman road between Romford and Ilford, on the edge of the great Becontree Estate. Its housing is predominantly 1920s–1930s semi-detached and terraced homes on arterial frontages and side streets, so householder work here is overwhelmingly rear extensions, side infills and loft conversions on those interwar houses.
There is no conservation area covering Chadwell Heath — that is a genuine, verified fact, not an omission. Its planning character is instead shaped by the consistency of the interwar suburb — regular building lines, semi-detached pairs and front-garden setbacks — read against the London Borough of Barking and Dagenham's householder design expectations. We treat that suburban grain, rather than a conservation designation, as the reference point when we design an extension.
Across streets like Waldegrave Road, Chadville Gardens and Farrance Road, demand is steady for rear extensions and loft conversions on the interwar stock. Because the district straddles the Barking & Dagenham and Redbridge boundary, we confirm which council a property sits under, check its permitted-development position against the borough-wide controls first, then prepare drawings that either stay within permitted development or are ready to validate as a full householder application.


Planning in Chadwell Heath (RM6): what to know before you apply
Barking and Dagenham assess Chadwell Heath extensions against the settled interwar suburban pattern, so matching original brick, render and roof form and respecting the gaps between semi-detached pairs matters more than on a mixed-typology road. There is no conservation area and no local Article 4 direction, so many houses retain permitted development rights for rear and loft work — but because the district straddles the Redbridge boundary, confirming the correct council, alongside neighbour amenity and building lines, is a key first step for any householder application.
Typical Chadwell Heath housing stock
Predominantly interwar semi-detached and terraced houses on arterial-road frontages and side streets, with some Victorian and postwar housing. The regular interwar plots and gardens are what make rear extensions and loft conversions such common projects across the district.

Wraparound Extension Drawings for Chadwell Heath (RM6) homes: the package and the process
Every wraparound extension drawings we prepare for an Chadwell Heath property is drawn to London Borough of Barking and Dagenham’s validation standards and tuned to the RM6 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 |
