The best kitchen extension for a Putney home depends on the house. A Victorian terrace wants a side return infill, an Edwardian semi can take a rear or wraparound, and the right choice turns a dark galley kitchen into the open plan heart of the home.
Thank you for reading this post, don't forget to subscribe!Across SW15, the single most effective move on most terraces is infilling the side return, and a well planned architects putney team will start there. Here is what actually works on each Putney house type.
What Is the Best Kitchen Extension for a Putney Terrace?
For a Putney Victorian or Edwardian terrace, the best kitchen extension is usually a side return infill, often combined with a modest rear extension, because it widens the narrow galley kitchen into a full open plan kitchen diner.
Most of Putney’s housing around the centre is period terraces with a side return, that narrow strip of land beside the original back kitchen. Filling it in is the classic SW15 move, because it adds width exactly where these houses are tight, and it floods the kitchen with light from a new roof lantern or rooflights.
Add a short rear extension to the infill and you get a wraparound, the most transformative single storey option, turning the whole back of the house into one bright, connected family space.
What Suits an Edwardian Semi or Villa in Putney?
The wider Edwardian semis and villas around Putney’s commons have more room to work with, so the options open up.
These homes can take a full width rear extension, a wraparound, or even a double storey rear extension, depending on the plot. The extra width means a kitchen island and a proper dining area fit comfortably, where a narrow terrace has to earn every centimetre.
For a semi with a side gap, a side extension can widen the kitchen further still, and the deeper gardens these houses enjoy mean a rear extension rarely costs you much usable outdoor space.
What Does a Kitchen Extension Cost in Putney?
Kitchen extension costs in Putney vary by type, and SW15 sits at the higher end of London rates given the area’s property values and specification expectations.
As a 2026 guide, a side return infill typically runs from around £45,000 to £85,000, a single storey rear extension from roughly £55,000 upward, and a wraparound commonly between £75,000 and £130,000, all including the build. The kitchen fit out, meaning units, worktops, appliances and the island, sits on top and depends entirely on your specification.
Period houses add one cost most people forget. Solid internal walls, suspended timber floors and original features need careful handling, and removing the rear wall for an open plan layout means a steel beam carried into the party wall, with structural calculations for Building Control.
Do You Need Planning Permission for a Kitchen Extension in Putney?
It depends on your exact street. Putney sits in the London Borough of Wandsworth, which has conservation areas at Putney Embankment, West Putney and the Dover House Estate, among others.
Outside those conservation areas, a single storey rear extension up to 3 metres on a terrace or semi, or 4 metres on a detached house, usually falls under permitted development, with the larger 6 metre route available through prior approval. Many Putney terraces keep these rights and can extend without a full application.
Inside a conservation area, the picture changes. Side extensions stop being permitted development, and larger or two storey schemes need full planning permission from Wandsworth, with designs that respect the building line and the local materials.
So the first step on any SW15 kitchen project is confirming whether your address sits inside one of Putney’s conservation areas.
Does a Kitchen Extension Add Value in Putney?
Yes. In Putney’s competitive SW15 market, a well designed open plan kitchen extension is one of the most value adding changes you can make.
Open plan kitchen dining spaces are strongly favoured by buyers and renters here, and on a period terrace the uplift from a quality side return or rear kitchen extension frequently clears the build cost. The return is strongest where the extension genuinely improves light and flow, rather than simply adding floor area, which is exactly what a side return infill with good overhead glazing delivers.
A tired galley kitchen is a weak point on an otherwise desirable Putney home. A bright, open kitchen diner is often what sells it.
The Light Problem Every Putney Kitchen Faces
One issue runs through almost every SW15 kitchen extension, and solving it is what separates a good result from a disappointing one.
Period terraces are deep and narrow, so pushing the kitchen back into the garden can leave the middle of the plan dark. Rear doors alone only carry daylight a few metres in. The fix is overhead glazing, a roof lantern or a run of rooflights over the deepest part of the room, which is what makes a side return or rear kitchen extension feel bright rather than boxed in.
Getting the glazing strategy right from the start, before the structure is fixed, is the difference between a room you want to be in and one that needs the lights on at noon.
The SW15 Takeaway
The best kitchen extension in Putney is the one matched to your house. Victorian and Edwardian terraces around the centre are made for the side return infill and the wraparound. Wider Edwardian semis and villas near the commons can go further, with rear, wraparound or double storey options. And whatever the type, the light strategy and the conservation area check decide how well it turns out.
Extension Architecture is a RIBA chartered and ARB registered practice working across London, including Putney and the wider South West, where the SW15 terrace and the Wandsworth planning framework shape every kitchen project. Match the extension to the house, solve the light, confirm the planning position, and a Putney kitchen extension becomes the brightest, most used room in the home.
