Side Return Extension Drawings in Nunhead SE15
Fixed-fee, MCIAT-chartered side return extension drawings for Nunhead (SE15) homeowners — London Borough of Southwark validation and local constraints handled from the start.
Nunhead (SE15) is a largely Victorian terraced neighbourhood on the rising ground between Nunhead Cemetery and Peckham Rye, and as the area has gentrified the demand has shifted firmly toward side-return, rear and loft extensions on family houses. Because so many properties share the same terraced footprint, Southwark's design expectations for extension depth and dormers here are well established.
Conservation pockets around Nunhead Cemetery, Nunhead Green and Telegraph Hill bring tighter control over roof form, materials and frontages than the surrounding streets carry. We check where a Nunhead property sits relative to those boundaries before recommending a permitted-development or full-application route, and draw the scheme to Southwark's residential guidance so it is assessed cleanly.


Planning in Nunhead (SE15): what to know before you apply
SE15 has no published householder Article 4 direction affecting typical Nunhead work, so many houses retain permitted development rights for rear and loft projects — but the conservation pockets around Nunhead Cemetery, Nunhead Green and Telegraph Hill are the exceptions where roof and frontage changes are more closely controlled.
Typical Nunhead housing stock
Victorian and Edwardian terraces on the streets rising between Nunhead Cemetery and Peckham Rye, largely two-storey family houses with rear gardens, plus a share of houses converted into flats.

Side Return Extension Drawings for Nunhead (SE15) homes: the package and the process
Every side return extension drawings we prepare for an Nunhead property is drawn to London Borough of Southwark’s validation standards and tuned to the SE15 constraints above. Here is what the drawing package covers and how the process runs from first survey to approval.
Behind most London terraces sits a narrow side alley, a metre or so wide, running from the front boundary to the back garden. A side return extension builds into that alley at ground floor, pushing the kitchen wall out to line up with the rest of the house and topping the new space with a glazed or pitched roof — often the single biggest transformation available to a galley kitchen without touching the garden at all. Because the alley typically sits hard against next door's boundary wall, this is also the extension type most likely to involve your neighbour directly, both through the planning application and through the Party Wall process.
DrawingsDirect draws side return extensions for full planning, coordinates the Party Wall paperwork your neighbour will need to see, and produces the structural calculations for the beam that carries the new roof, all under one MCIAT-chartered team and one fixed fee. If you are also extending the rear at the same time, our Wraparound Extension page covers the combined project.
Do I need planning permission for a side return extension in London?
Permitted development rights for side extensions are narrower than for rear extensions: they generally cap the extension at a single storey, restrict its width to no more than half the width of the original house, and limit its height. In practice, a full-depth side return running the length of a Victorian or Edwardian terrace usually exceeds one or more of these limits, so most side return projects are drawn and submitted as a full householder planning application.
Conservation area status and Article 4 directions, common across inner London terraces, remove permitted development rights for side extensions entirely in many streets, reinforcing the need for a planning application. We check your property's status before drawing.
What does a side return extension involve?
A side return infills the alley at ground floor level, structurally opening the original flank wall of the kitchen into the new space so the two areas read as one room. Unlike a rear extension, which is bounded on three sides by your own garden, a side return is bounded on one long side by the neighbouring property, which shapes almost every decision in the design, from where the roof glazing sits to how deep the new foundations need to go.
- New flank wall built out to align with the rear of the house, following the boundary line
- Original external wall between kitchen and alley opened up and supported on a steel or glulam beam
- Roof over the new space either glazed in full, glazed in a strip along the boundary for a 'light well' effect, or pitched and tiled to match the main roof
- Kitchen re-planned across the combined footprint, often incorporating an island once the room widens
