Planning building work in Lewisham? Whether you are extending a terraced house in Brockley, converting a loft in Hither Green, altering a property in Catford, or carrying out excavation close to a neighbour in Deptford, the Party Wall etc. Act 1996 may apply.
Express Party Wall helps homeowners, architects, landlords and developers manage the process correctly from the start. We prepare and serve Party Wall Notices, arrange Schedule of Condition reports, handle neighbour responses and prepare Party Wall Awards where required.
If you are unsure whether your project needs a notice, send us your drawings or a short description of the work and we can point you in the right direction.
Lewisham has a wide mix of Victorian terraces, converted flats, maisonettes, semi-detached homes, newer apartments and tightly positioned residential streets. Because many properties share walls, boundaries or closely spaced foundations, even a simple home improvement project can trigger Party Wall requirements.
The most common Lewisham projects we assist with include loft conversions, rear extensions, side returns, chimney breast removals, internal structural alterations, boundary wall works and excavation for new foundations. Getting the correct notice served early helps prevent delays once builders are ready to start.
Our role is to make the process clear, practical and properly documented, so both the building owner and adjoining owner understand what is happening before work begins.
Not every building project needs a Party Wall Notice, but many common home improvement works in Lewisham do. The Act usually applies when the work affects a shared wall, is close to a boundary, or involves excavation near a neighbouring property.
| Type of Work | Why It May Need a Notice |
|---|---|
| Loft conversion | Steel beams may be inserted into a shared party wall |
| Rear or side extension | New foundations may be close to a neighbour’s property |
| Chimney breast removal | The chimney may be attached to a shared wall or structure |
| Boundary wall work | Building on, up to, or altering a shared boundary may be notifiable |
| Basement or deeper excavation | Excavation may affect nearby foundations |
| Internal structural alterations | Works may affect party walls, beams, or shared structures |
If your plans show work close to another property, it is always better to check early rather than risk serving notices too late.
Terraced homes are common across Lewisham, Brockley, Catford, Hither Green and New Cross. Loft conversions, rear extensions and chimney works often involve shared walls, making Party Wall Notices a common requirement.
Converted properties can involve more than one adjoining owner. In some cases, notices may need to be served on freeholders, leaseholders, or neighbouring flat owners depending on the structure and ownership arrangement.
For semi-detached homes, work to the shared wall or excavation close to the neighbouring foundations may require notice. A Schedule of Condition can help protect both sides before work begins.
Side return extensions, garden walls and new foundations close to the boundary are common reasons why Lewisham homeowners need Party Wall advice before starting construction.
Once the correct Party Wall Notice has been served, your neighbour has a set period to respond. Their response decides the next stage of the process.

| Neighbour Response | What It Means |
|---|---|
| Consent | The work can usually proceed once the notice period and any agreed protections are dealt with |
| Dissent and appoint an Agreed Surveyor | One impartial surveyor acts for both owners and prepares the Party Wall Award |
| Dissent and appoint their own surveyor | Each owner has a surveyor and the Award is agreed between the appointed surveyors |
| No response | This is treated as a dispute and the surveyor process can begin |
We help manage this stage clearly so the process does not become confusing or unnecessarily delayed.

Many delays happen because the Party Wall process is left until builders are ready to start. By that point, the notice period may create an avoidable delay.
A short check at the start can save weeks of delay later, especially for loft conversions, extensions and excavation works.
The cost of Party Wall services in Lewisham depends on the type of work, the number of adjoining owners, whether your neighbour consents, and whether a Party Wall Award is needed. Straightforward notice-only matters are usually cheaper than projects where surveyor appointments and Awards are required.
| Service | Typical Fee | When You May Need It |
|---|---|---|
| Party Wall Notice | From £49 | For serving the correct legal notice before work begins |
| Schedule of Condition | From £250 | To record the neighbouring property before construction starts |
| Party Wall Award | From £500 | When a neighbour dissents or does not respond to the notice |
| Agreed Surveyor Route | Quoted based on the project | When both owners agree to use one impartial surveyor |
For Lewisham projects with more than one adjoining owner, converted flats, complex excavation, or multiple notices, the cost may vary. We can review your plans and confirm the most suitable route before you move forward.

1) Do I need a Party Wall Notice for an extension in Lewisham?
Often yes—especially if you’re excavating near a neighbour or building on/near the boundary. Send your drawings and we’ll confirm quickly.
2) How much notice do I need to give?
Many works require 1–2 months’ notice, depending on the type of work.
3) What happens if my neighbour doesn’t respond?
A non-response is treated as a dissent, triggering the surveyor procedure so the matter can progress correctly.
4) Can one surveyor act for both parties (Agreed Surveyor)?
Yes—if both parties agree, one surveyor can act for both, often efficient for straightforward projects.
5) What is a Schedule of Condition?
A dated photographic and written record of the adjoining property before works begin. It helps prevent disputes later.
6) Who pays the party wall surveyor fees?
In most cases, the building owner carrying out the works pays reasonable costs.
7) Does a Party Wall Award replace planning permission?
No. Planning/building control are separate. The Award deals with protections, access, and responsibilities under the Party Wall Act.
8) Are side return extensions covered by the Party Wall Act?
Often, yes—because they typically involve boundary-close excavation and structural work. We’ll confirm quickly from your plans.
