Home Improvements · South LondonRenovations in Dulwich, SE21 and SE22
Kitchens, bathrooms and full-home renovations across Dulwich — the Victorian and Edwardian villas of East Dulwich, the larger houses around Dulwich Village and College Road, and the interwar stock beyond.
What we are working with in Dulwich
Dulwich has larger houses and larger gardens than the rest of our patch, which changes both the typical job and the typical obstacle.
Victorian and Edwardian villas and terraces
East Dulwich has generous late-Victorian and Edwardian housing, much of it still in single occupation. Bigger houses mean full-house work comes up more often here than single-room refits: whole-house rewires, heating replacement, and reconfiguring a ground floor around a kitchen-diner.
Larger detached and semi-detached houses
Around Dulwich Village, College Road and Sydenham Hill the stock is larger again, with the scope and the budget of a full renovation rather than a room.
Interwar suburban stock
The 1920s and 1930s houses further out have cavity walls, which makes them the one part of our area where cavity wall insulation is a straightforward option, and original services that are usually due for replacement.
Rear extensions
Larger gardens make a rear or wrap-around extension the common ask here. That is what makes the tree constraint below more than a technicality.
Permissions and constraints in Dulwich
Dulwich has one constraint that exists almost nowhere else, and a second that quietly moves budgets.
The Dulwich Estate scheme of management
A large proportion of property in SE21 and parts of SE22 is subject to the Dulwich Estate's scheme of management. It requires the Estate's own written consent for external alterations, extensions, window changes and sometimes boundary treatments and exterior paint colours — entirely separate from, and in addition to, planning permission. Getting planning consent and starting work without Estate consent is a real and common mistake, and the Estate can enforce against it. Its approval timeline needs building into the programme from the outset.
Conservation areas
Dulwich Village, Sydenham Hill Ridge and Kingswood conservation areas cover much of the area, with the usual reduction in permitted development rights.
Tree preservation orders
Trees are protected unusually widely across Dulwich. That matters for foundations: building near a protected tree, particularly on clay, can push footings substantially deeper under the applicable foundation guidance. It is a genuine budget item on a rear extension and it should be established at design stage, not discovered when the trial holes are dug.
Building control and party walls
Notifiable work goes through Southwark building control or an approved inspector, with party wall agreements needed for structural work on attached houses.

Dulwich renovation FAQs
What is the Dulwich Estate scheme of management? +
A private set of restrictions covering a large part of Dulwich, administered by the Dulwich Estate and operating independently of the planning system. It typically requires their written consent for extensions, external alterations and window changes. You can hold valid planning permission and still be in breach of the scheme, so both consents need to be in hand before work starts.
Why would a tree change my extension cost? +
Because roots affect the ground the foundations sit on. Near a protected tree on clay soil, foundation guidance can require significantly deeper footings to avoid future movement. Deeper footings mean more excavation, more concrete and more spoil to remove. Establishing it at design stage keeps it a known cost rather than a mid-build surprise.
Do larger Dulwich houses need a different approach? +
Mostly in sequencing rather than technique. A whole-house renovation has more trades overlapping, longer lead times on items like cabinetry and stone, and more decisions that block other decisions. That is why the planning stage is written down before anything is stripped out.
