Kitchen Extensions in Dulwich
Dulwich has some of the best housing stock in South London. Victorian terraces in East Dulwich, generous Edwardian semis towards the Village, larger detached houses near the park. Most share the same limitation: a kitchen that doesn't match the quality of the rest of the house. We fix that.

Why Dulwich Kitchens Need Extending
Dulwich houses were built when kitchens were functional rooms, not living spaces. The original scullery at the back of an East Dulwich terrace made sense when someone else was doing the cooking. The galley kitchen in a Lordship Lane Victorian worked fine before open-plan became how families actually live.
Now those kitchens feel like the weak point in otherwise excellent houses. You’ve got high ceilings, original fireplaces, a decent garden. Then the kitchen: narrow, dark, cut off from the rest of the ground floor.
An extension changes that. Push out into the garden by three or four metres, fill in the side return if you have one, and the kitchen becomes the room you actually use. Space for an island, a table where people can sit, bi-fold doors that open onto the garden. The rest of the house is good. The kitchen can match it.
We’ve built extensions across Dulwich for years. From the Victorian terraces around Lordship Lane and East Dulwich Road to the larger houses in Dulwich Village and towards Sydenham Hill. We know what Southwark planning looks for, which streets have rear access, and how to work with the period details that make Dulwich houses worth extending in the first place.
Extension Types
Extension Options for Dulwich Houses
Return Extensions
The most common choice in Dulwich. Extend straight out into the garden, typically 3–5 metres. Dulwich gardens are often deeper than inner London, so you can add serious space without losing the whole lawn. Works well on Victorian terraces and Edwardian semis. Creates a kitchen-diner that opens onto the garden through bi-folds or sliding doors.
Side Return Extensions
For Victorian terraces with that narrow passage down one side. Fill it in and the kitchen gets significantly wider. A rooflight along the length brings natural light deep into the room. Popular on the streets off Lordship Lane and around East Dulwich station where the terraces have consistent layouts.
Combined Side Return + Rear
Extend into the side return and push out at the back. Creates an L-shaped kitchen that wraps around the original house. The most popular option for Dulwich terraces where you want both the width gain and the extra depth. Usually the best use of the available space.
Wraparound
For larger properties near the Village or towards Sydenham Hill. Extend around two sides of the house to create a substantial kitchen-living space. Generally needs planning permission but the larger plots can absorb a bigger footprint without overwhelming the garden.

"Our terrace on Landcroft Road had a tiny galley kitchen that we'd put up with for years. The extension added about 25 square metres and completely changed how we use the ground floor. Joel's team managed the party wall process with both neighbours, dealt with Building Control, and finished on schedule. The quality of the plastering and the way they matched the new brickwork to the original house was impressive. We should have done it years ago."

How It Works
From first conversation to your new kitchen, here’s the process for Dulwich extensions.
Common Questions About Dulwich Extensions
Dulwich Village and the streets immediately around it are a conservation area, as is part of the Dulwich Estate. Most of East Dulwich (around Lordship Lane, East Dulwich Road, Landcroft Road) is not in a conservation area. Southwark has maps on their website showing exact boundaries. We check your specific address and advise what it means for your project.
Most rear extensions up to 3m (or 4m for detached houses) fall under Permitted Development and don’t need planning permission. Side returns are usually fine too. Conservation areas have different rules and may require a full application. We assess your property specifically during the consultation.
Some Dulwich properties are on the Dulwich Estate, which has its own approval process on top of council planning. If your house has an Estate lease, you’ll need their consent for external alterations. We can advise on how this works, though the Estate application is usually the homeowner’s responsibility.
Most extensions take 10–14 weeks to build. Add 8–12 weeks beforehand for planning (if required), Building Regulations, and party wall agreements. Victorian terraces share walls with neighbours on both sides, so party wall notices are almost always needed.
Some do. The streets with back lanes (parts of Whateley Road, some roads off Barry Road) have rear access, which makes deliveries easier. Most Victorian terraces don’t, so materials come through the house. We plan for this and protect floors and doorways throughout.
RICS research suggests 10–15% for a well-designed kitchen extension. In Dulwich, where extended houses with open-plan kitchens are in demand, the uplift is often at the higher end. A £75,000 extension on a £1m house could add £100,000–£150,000 to the value, though this depends on finish quality.
Building Extensions in Dulwich
Dulwich falls within Southwark council, though the Dulwich Estate adds another layer for some properties. Southwark planning is generally reasonable for straightforward rear extensions. They’re more careful around the Village conservation area, but even there, rear extensions that aren’t visible from the street usually get approved.
The housing stock varies more than people expect. East Dulwich around Lordship Lane has tight Victorian terraces, similar to Peckham or Camberwell. Towards the Village and Sydenham Hill, the houses get larger, the plots deeper, and the architecture shifts from Victorian to Edwardian and interwar. Each type needs a different approach.
Access is mixed. Some streets have rear lanes, which makes building work significantly easier. Most terraces don’t, so materials come through the house. We’ve extended houses on Landcroft Road, Dunstans Road, Goodrich Road, and plenty of streets around East Dulwich station where there’s no rear access. It takes more planning but it’s entirely manageable.
Parking is permit-controlled across most of Dulwich. We arrange permits for works vehicles before starting. Skip permits through Southwark take about a week. On streets without rear access, we coordinate deliveries to minimise time blocking the pavement.
One thing worth noting: Dulwich has seen steady demand for extensions over the past decade. Your neighbours have probably been through this before or watched next door do it. That familiarity tends to make party wall discussions easier.
