Planning works on a Dulwich home, or just received a Party Wall Notice from a neighbour? LENIO Party Wall Surveyors handles the whole process for you.
Looking for a party wall surveyor in Dulwich? LENIO Party Wall Surveyors works across Dulwich Village, East Dulwich, West Dulwich and Herne Hill, on both sides of the wall.
Dulwich is part of our South London coverage, and a busy party wall area. From East Dulwich terraces to the larger houses of Dulwich Village, most extensions, lofts and basements here engage the Party Wall etc. Act 1996.
Most Dulwich homeowners ask this before a side return, loft or basement, usually when an architect raises it. Whether you need a notice depends on the works and how close they sit to your neighbour.
This guide sets out exactly which works are notifiable, how proximity to the boundary matters, and what to do if you are uncertain.
On East Dulwich's tight terraces, and even on the larger plots of Dulwich Village, works usually affect a shared wall. Often they sit close to next door too. That is why most projects here are notifiable, and the party wall notice Dulwich projects require is the first formal step. Our guide on whether you need a Party Wall Notice covers it in full.
Dulwich is really two markets. East Dulwich, around Lordship Lane, is a grid of Victorian terraces where the side return and loft conversion are the standard family project. The streets are close, so almost every job touches a neighbour.
Dulwich Village and West Dulwich are grander. Larger Victorian and Georgian houses sit on generous plots, many within conservation areas and the historic Dulwich Estate. Here the projects tend toward bigger rear extensions and basements.
Whichever part of Dulwich you are in, the party wall principle is the same. Where works affect a shared wall, or dig near a neighbour's foundations, the right notice has to be served first, and reach the right people before the build begins.
Most Dulwich projects engage the Act through one of four works. Each triggers a different notice.
The classic Dulwich project. New foundations near the neighbour, or building to the boundary, bring the Act into play under the excavation and boundary provisions.
Sections 1 & 6Steel beams bearing on the party wall, or raising it to form a gable, are structural works served under a Party Structure Notice.
Section 3Common on the larger Dulwich Village homes. Digging below and close to neighbouring foundations almost always triggers the Act, usually with more than one notice.
Section 6Removing a breast that forms part of a shared stack is work to a party structure. That applies even when the rest of the job is on your side.
Party StructureThe most common mistake we see in Dulwich is assuming that Dulwich Estate consent, or planning permission, also covers the party wall. Much of Dulwich sits under the Dulwich Estate Scheme of Management, which controls external alterations but does not deal with your neighbour's rights.
The Party Wall etc. Act 1996 is separate from both planning and the Estate scheme. You can hold Scheme of Management consent and planning approval, and still need to serve a Party Wall Notice before notifiable works begin.
Owners often spend months on Estate and planning consents, then meet the party wall process at the last minute. Running it alongside those approvals keeps your start date on track.
Wherever you are in the process, LENIO Party Wall Surveyors covers it for Dulwich owners. The work breaks down into a handful of clear services, whether you are the Building Owner or the Adjoining Owner.
Working out which notice a Dulwich project needs, and serving it correctly on the right Adjoining Owners, is where the process starts. Get this step right and the rest tends to follow.

Explore Agreed Surveyor →Three terms Dulwich homeowners ask about most, and what each one actually means for your project.
A Party Wall Award is the document surveyors prepare when a neighbour dissents to your notice. It sets out how the works are carried out, the working hours, access arrangements and a Schedule of Condition. You only need one if your neighbour dissents, or does not respond within 14 days. If they consent in writing, the works proceed on the notice alone.
Many homeowners say party wall agreement when they mean either written consent or the Award that follows a dissent. A verbal yes gives no protection. If your neighbour consents in writing, that written consent is the agreement Dulwich owners rely on. If they dissent, the Award becomes the formal agreement that governs the works.
Before works begin, a party wall survey records the condition of the neighbouring property in photographs and notes. On Dulwich's older terraces and period houses, that baseline is what settles any later question about damage. Both owners hold the same record, so neither side can argue about what the property looked like before the works.
In most cases, a short look at your plans is enough to confirm whether you need a notice, which one applies, roughly how long it will take, and what happens next. LENIO Party Wall Surveyors offers this initial advice for free, with no obligation to go further. For Dulwich, that usually starts with a look at how your side return & rear extensions sits relative to the boundary.
Homeowners in Dulwich need more from a party wall surveyor than a letter dropped through a neighbour's door. The role is to work out exactly which notices your project triggers, serve them on every owner who qualifies, and clear any dispute so the build can start on time.

Call LENIO TodayMost party wall situations are not disputes waiting to happen. They are simply a legal step that has to be done properly, so the works go ahead while the property next door stays protected. A specialist party wall surveyor in Dulwich manages that quietly, without putting the neighbour relationship at risk. Here that most often means side return & rear extensions, so it is usually the first thing we ask about.
What goes wrong usually comes down to the same few things. A notice served incorrectly has to be served again, which costs weeks. Skipping the Schedule of Condition leaves you with nothing to fall back on if a crack appears later. And a neighbour who is not kept informed is more likely to dig in and dissent.
LENIO Party Wall Surveyors would rather reassure than alarm. Advice at the outset is free, and you get a clear, fixed quote once we have seen the drawings.

Yes. The Dulwich Estate Scheme of Management controls external alterations, but it is separate from the Party Wall Act. It does not deal with your neighbour's rights, so you still serve the right notices for notifiable works.
We recommend running the party wall side alongside your Estate and planning applications, so nothing holds up your start date.
Often, yes. On East Dulwich's tightly packed terraces, a side return or loft usually affects a shared wall or digs close to next door. A party wall notice in Dulwich is usually required for these works.
A quick look at your drawings confirms which notices apply before you commit to a start date.
Yes, almost always. A basement digs below and close to neighbouring foundations, which triggers the Act, usually under more than one notice. On larger Dulwich Village homes, basements are increasingly common.
Because basements carry structural risk, the Award goes further than for a simpler job, and a surveyor who reads the engineering is worth having.
There is no single price, because the cost depends on how your neighbour responds and how many owners are involved. A consented notice sits at the low end, while a party wall award in Dulwich, after a dissent, costs more.
LENIO gives free initial advice and a clear quote after reviewing your drawings. You will know the cost before any work begins.
