Wraparound Extension Drawings in Lewisham
Fixed-fee, MCIAT-chartered wraparound extension drawings for Lewisham homeowners — London Borough of Lewisham validation and local constraints handled from the start.
Lewisham is terraced South-East London: the Victorian and Edwardian streets of Brockley, Forest Hill and Hither Green make side-return extensions and hip-to-gable loft conversions the borough's signature projects, giving way to the Georgian-fringed heath at Blackheath, the historic Deptford High Street and the post-war estates around Catford and central Lewisham. The right route depends heavily on the street — a rear extension in Hither Green is a very different application from a roof alteration in the Brockley conservation area.
Design control shapes much of the borough. Conservation areas at Blackheath, Brockley, Telegraph Hill, Deptford High Street, Ladywell and Lee Manor govern materials, rooflines and front elevations, while the dense terraced streets bring side-return and rear-depth control and party-wall sensitivity between neighbours. Sloping sites and long views across the Honor Oak and Forest Hill ridges further shape extension design, and a borough-wide Article 4 direction removes permitted development for change of use to an HMO (C3 to C4) anywhere in the borough — though it leaves standard family extensions and lofts unaffected.
We prepare Lewisham planning drawings to the council's householder and validation standards, checking permitted development eligibility for terraces and semis first and designing to conservation-area expectations where Blackheath, Brockley or Telegraph Hill applies. It is the same council-accepted drawing set an architect would produce, usually at around 30% less, with a fixed fee agreed up front, a roughly seven-day drawing turnaround and free redraws until the London Borough of Lewisham approves. Most householder applications are decided within the statutory eight-week period once validated, so we draw to the validation checklist from the outset to avoid the queries that cause most delay.
Planning in Lewisham: what to know before you apply
Lewisham operates a borough-wide Article 4 direction removing permitted development rights for HMO conversions, and controls design within its conservation areas — Blackheath, Brockley and Telegraph Hill in particular. For the borough's abundant terraces, side-returns and hip-to-gable lofts frequently qualify as permitted development; we confirm the designation for your street before drawing.

Wraparound Extension Drawings for Lewisham homes: the package and the process
Every wraparound extension drawings we prepare for a Lewisham property is drawn to London Borough of Lewisham’s validation standards and tuned to the local 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 |
