Wraparound Extension Drawings in Herne Hill SE24
Fixed-fee, MCIAT-chartered wraparound extension drawings for Herne Hill (SE24) homeowners — London Borough of Lambeth validation and local constraints handled from the start.
Herne Hill (SE24) straddles the Lambeth–Southwark boundary around Brockwell Park, with its Lambeth side made up of desirable late-Victorian and Edwardian streets — including the Poets' Corner terraces off Railton Road. Rear and loft projects are the staple here, shaped by the conservation areas that cover much of the neighbourhood. (The Stradella Road conservation area lies just across the boundary in Southwark, so properties there answer to a different council.)
Lambeth's Brockwell Park and Herne Hill conservation areas closely control frontages and rooflines around the park and the Poets' Corner streets, and the low ground near the culverted River Effra brings flood-risk considerations. We check where a Herne Hill property sits relative to those designations — and which side of the borough boundary it falls — before recommending a permitted-development or full-application route.
Planning in Herne Hill (SE24): what to know before you apply
SE24 has no householder Article 4 direction, so many Herne Hill houses retain permitted development rights for rear and loft work — but Lambeth's Brockwell Park and Herne Hill conservation areas are the exceptions, controlling frontages and rooflines around the park and the Poets' Corner streets, and low-lying parts near the old River Effra carry flood-risk considerations. SE24 straddles the Lambeth–Southwark boundary, so we confirm which council a property falls under before advising.
Typical Herne Hill housing stock
Late-Victorian and Edwardian terraces and semi-detached houses on the streets around Brockwell Park, including the well-known Poets' Corner streets off Railton Road, with mansion flats along the main roads.

Wraparound Extension Drawings for Herne Hill (SE24) homes: the package and the process
Every wraparound extension drawings we prepare for an Herne Hill property is drawn to London Borough of Lambeth’s validation standards and tuned to the SE24 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 |
