House Extension East Dulwich SE22: Most of It Is Not Designated At All
People move to East Dulwich and assume the planning position matches Dulwich Village up the road. It does not. The conservation area here is small, and Southwark files it under Peckham. The Gardens, designated in June 1988, sits on the west side of Peckham Rye Common and covers a neat square of houses around a central green with the adjoining streets of Oakhurst Grove and Kelmore Grove. That is the extent of it. The great majority of SE22 addresses are not inside a conservation area at all.
What the area does have is stock worth working on. Southwark’s own planning report describes the East Dulwich Grove setting as mainly modest two and three storey late Victorian terraces and semi-detached villas, with some modern infill. Around fifty-seven per cent of households here live in a whole house rather than a flat, which is the highest figure of any neighbourhood in Lambeth or Southwark, where three quarters of households are in flats. This is one of the few genuinely house-based markets in inner south London.
But undesignated does not mean unregulated, and two things catch people out. Southwark applies an area-specific planning document to East Dulwich that most residents have never heard of. And a number of titles here still carry covenants from a private landowner, enforceable quite separately from anything the council decides. At Design And Build the design team, the engineers, the surveyors and the trades are all our own staff, working across SE22 under one roof.

House extension East Dulwich on an 1880s terrace
The Gardens, Oakhurst Grove and Kelmore Grove
Southwark describes the conservation area plainly enough. The scale of buildings runs from two storey terraces to large four and five storey houses, with a good deal of consistency in materials and detailing reflecting the sixty to seventy year period of the nineteenth century when the area was developed.
If your house is inside that boundary, the national rules narrow automatically: side additions, cladding and various roof alterations all fall away before any local policy is considered. If it is outside, and most SE22 houses are, permitted development applies normally. The boundary is published and takes minutes to check. Borrowing the designation because a neighbouring street has it is how schemes get refused.
Policy coverage is not designation
Southwark operates a Dulwich supplementary planning document covering East Dulwich, Herne Hill and Dulwich Village, along with a small area west of Peckham Rye. It is guidance rather than designation, and the two are frequently confused.
The distinction matters. Being inside the document’s boundary does not make a house listed, does not put it in a conservation area, and says nothing about how it was built. What it does mean is that an officer assessing your application has a set of area-specific expectations to measure it against. Knowing what they are before the drawings are finished is worth more than arguing afterwards.
Ridge heights, dormers and the 2.2 metres
Look at what SE22 actually applies for and one pattern repeats. Loft conversions with L-shaped dormers, and with them a small, precise raise to the ridge. Recent applications name 200mm, 275mm, 278mm, 300mm and 400mm.
Those figures are not arbitrary. The Victorian butterfly and double-pitched roofs here generally clear the 2.2 metres of head height a conversion needs, but only just, and a few centimetres decides whether a room works. Raising a ridge by 300mm takes a scheme outside permitted development and into a full application, which is precisely why so many of these appear on the register. Our structural engineers measure the existing roof before anyone commits to a figure.
Builders East Dulwich, and the estate that never went away
Dulwich Estate covenants and the concurrent application
A number of SE22 titles still carry covenants from the historic Dulwich Estate, and they are enforceable independently of the council. Firms working here describe confirming them by title deed search and then submitting to Southwark and to the estate’s managers in parallel, using identical drawings.
Not every house is affected, which is the awkward part. In Dulwich Village it is assumed; in East Dulwich it has to be established. The deeds answer it, and they answer it before the design starts rather than after. We check the title as a matter of course on any SE22 project.
What conveyancing turns up years later
The consequence of skipping that check does not appear during the build. It appears when you sell.
Work carried out without building control sign-off, and particularly work that did not satisfy a covenant where one applied, surfaces during conveyancing and can materially affect a sale. Buyers’ solicitors ask for the paperwork, and an indemnity policy is a poor substitute for having done it properly. Where a scheme needs no permission at all we obtain a lawful development certificate so the position is documented from the start.
House renovation East Dulwich along Lordship Lane
Goose Green, Barry Road and Underhill
The East Dulwich ward was abolished in 2018 and the area now splits across Goose Green, Dulwich Hill and Champion Hill. Goose Green covers the centre, including Lordship Lane, and holds around thirteen and a half thousand residents in barely a square kilometre.
Lordship Lane itself is a designated district town centre, which changes what is possible above and behind the shops. Around it, Barry Road, Underhill Road, Melbourne Grove, Fellbrigg Road and the Landells and Friern streets are consistent late Victorian terraces. Consistency is the point: what has been approved two doors down is the strongest argument you have. Interior design joins while the layout can still move.
Density zones nobody mentions
Buried in the Dulwich document is a distinction with real consequences. The suburban zone covering much of the area carries a recommended density range of two hundred to three hundred and fifty habitable rooms per hectare. The urban zone across the north of the area runs from two hundred to seven hundred.
For a single house extension that rarely bites. For anything creating additional units, or for a substantial reworking of a large villa, it decides what the council will entertain. Which zone an address falls in is not something the street tells you.
Design and build East Dulwich to the Dulwich
Nobody sub-contracted on an SE22 site
An East Dulwich project can involve a conservation boundary that may or may not reach you, an area planning document, a private covenant enforceable by a third party, building control, and a party wall on both sides of a terrace.
Those are not separate jobs held by separate firms. Here the survey, the drawings, the structural design and the construction sit under one agreement, where the Party Wall etc. Act 1996 applies the notices come from surveyors on our staff, and we lodge with Southwark ourselves and see the application through. One construction company, one price, one person accountable.
Construction company East Dulwich, and the consent that is not the council's
Most building firms in SE22 will tell you whether you need planning permission. Rather fewer will ask to see your title before they quote.
That is the difference here. Southwark is one authority over your house. A private covenant, where one exists, is another, and it answers to nobody at the council. A scheme approved by the borough and refused by an estate is still a scheme you cannot build. Establishing both positions costs a morning at the start and saves considerably more than that later.
Area We Cover
Send the address and the title deeds
Two documents settle nearly all of it. The address tells us whether The Gardens boundary reaches you, which density zone applies, and what the neighbouring approvals look like. The deeds tell us whether a covenant is in play.
Send both. What comes back covers which consents apply and in what sequence, how much the roof will give you, and the route we would take. Our patch is East Dulwich and SE22 — Goose Green, Lordship Lane, Barry Road, Underhill Road, Melbourne Grove, East Dulwich Grove and the Peckham Rye fringe — along with Dulwich, Peckham, Herne Hill, Forest Hill and the neighbouring SE districts.
No charge for the survey. Here it opens with a document search rather than a tape measure.
