The Dulwich Estate Scheme of Management: what it means before you extend or convert

If you own a house in Dulwich and you are planning an extension, a loft conversion, new windows, or anything that changes how the property looks from the outside, there is a step most homeowners only find out about halfway through. On top of Southwark planning and Building Control, you need separate written approval from the Dulwich Estate's Scheme of Management Office. Skip it and you can have full council planning permission and still be told to stop.

I run All Well Property Services across South East London and we work on Dulwich houses regularly. The Scheme catches people out often enough that it is worth explaining properly, before you have an architect drawing up plans that the Estate will not pass.

What the Scheme of Management is

Much of Dulwich, across SE21 and parts of SE22 and SE24, sits on land owned by the Dulwich Estate, a charity that has managed the area for centuries. When leaseholders bought the freeholds of their homes, the Estate kept a Scheme of Management: the right to control changes to the outside of properties, so the character of the area and the amenity of neighbours are protected.

In plain terms, the freehold is yours, but the Estate still has a say over the external appearance of your house. That say is run from the Scheme of Management Office at The Old College, Gallery Road, SE21 7AE. Any work that affects how the property looks from the outside needs their written approval before it starts.

What actually needs Estate approval

It is broader than people expect. The Estate's Guidelines for Residents cover applications for:

• Extensions and loft conversions
• Replacement doors and windows
• External repairs to roofs, chimneys and walls
• Conservatories, garden structures and swimming pools
• Boundary changes and hard standings such as a driveway
• Solar panels and EV charging points
• Satellite dishes, change of use and new build

The rule underneath the list is simple: any change to the external appearance of the property needs the Estate's prior written approval. A like-for-like repair using matching materials is usually straightforward. Swapping timber sash windows for uPVC, rendering a brick frontage, or putting a dormer on a front roof slope is where applications get refused.

The part that catches people out: two separate approvals

This is the bit worth reading twice. Approval under the Scheme of Management is separate from, and in addition to, your local authority's planning permission. Dulwich spans three boroughs, so depending on your street that local authority is Southwark, Lambeth or Lewisham, plus Building Control.

The two approvals are not connected. Getting consent from one does not mean you will get it from the other, and they assess against different things. Two consequences follow that I see trip homeowners up:

Some work that needs no planning permission at all, because it falls under permitted development, still needs Estate approval if it changes the outside of the house. Permitted development rights do not override the Scheme.

And full planning permission from Southwark is not a green light to build. If you start without the Estate's approval, you are in breach of the Scheme, and the Estate enforces it. Unwinding finished work, or redoing windows in the right material, costs far more than getting the application right first time.

How the process works

You apply to the Scheme of Management Office for the works you are planning. The Estate publishes its Guidelines for Residents for each type of job, so you can see the scale and detail they expect before you design anything. After you apply there is a review stage, and larger or more sensitive schemes can go to the Estate's Advisory Committee. There is also an Annual Charge that homeowners on the Estate pay towards managing the Scheme.

The Estate sets its own fees and timescales and updates them, so I am not going to quote a number that might be wrong by the time you read this. Build the Estate application into your programme from the start rather than treating it as paperwork to sort out later, because running it alongside the council application is what keeps a project on schedule.

The mistakes I see most often in Dulwich

Starting on site with council permission but no Estate approval. It feels like the planning is done, so work begins, and then a neighbour or the Estate flags it.

Treating window replacements as a free swap. On a period Dulwich house the Estate cares about material and detail, not just the opening. Timber, slim sightlines and the right glazing pattern matter, and uPVC is usually a refusal.

Designing to the council's brief alone. An extension or dormer that Southwark would wave through can still be the wrong scale or material for the Estate's Guidelines. Designing for both from day one avoids two rounds of drawings.

How we handle it for Dulwich clients

All Well Property Services is a building and renovation company based in Anerley, and it works on period homes across Dulwich, in SE21 and SE22. All Well Property Services is NICEIC approved, FENSA registered and CHAS accredited, and it is registered at Companies House under number 12721034. We have run these approvals on Dulwich houses since 2020.

When we survey a Dulwich house we check which authority you fall under and whether you are inside the Scheme, before any design work starts. We design to both the council's requirements and the Estate's Guidelines together, match materials and details to what the Estate expects on a period property, and prepare both submissions so they run in parallel rather than one after the other. One project manager coordinates the Estate office, the council and the build, so you are not the one chasing three sets of approvals.

If you are weighing up an extension, a loft conversion or new windows on a Dulwich house and you are not sure where you stand with the Estate, that is exactly the kind of thing we work out on a free site visit. We will tell you what the Estate is likely to accept before you spend money on plans that will not pass.
