We provide party wall surveying support across South East London, including postcodes SE1, SE2, SE3, SE4, SE5, SE6, SE7, SE8, SE9, SE10, SE12, SE13, SE14, SE15, SE16, SE17, SE18, SE19, SE20, SE21, SE22, SE23, SE24, SE25, SE26, SE27 and SE28.
A Southeast London page should not read like a single-borough page because the housing stock and project mix are more varied. A terrace extension in Peckham raises different practical issues from a basement project in Blackheath, and both are different again from loft works on a suburban property in Sidcup or Bexley.
That is why a broader Southeast London service page should focus on:
We assist a wide range of clients across Southeast London, including homeowners planning residential improvements, developers managing more involved schemes, and architects or project teams who want the party wall side addressed early.

Southeast London covers a large and surprisingly varied part of the capital. Around Deptford, New Cross, Brockley, Peckham and Lewisham, Victorian terraces and converted houses are a familiar sight. Move towards Greenwich and Blackheath and the mix becomes broader, with period homes, flats, larger houses and modern developments. Further east towards Bexley, Sidcup and Welling, semi-detached and detached family homes become much more common.
That variety matters when building work is being planned. A loft conversion in Brockley may involve work to an existing shared wall, while a rear extension in Sidcup may be more likely to raise questions about excavation close to a neighbouring foundation. In Greenwich or Blackheath, ownership arrangements, converted buildings and older structures can add another layer to the party wall process.
Express Party Wall helps homeowners, landlords, developers, adjoining owners and property professionals across Southeast London deal with the requirements of the Party Wall etc. Act 1996. We can review proposed works, prepare and serve notices, carry out Schedules of Condition and deal with Party Wall Awards where the formal surveyor process is required.
Our coverage includes Lewisham, Blackheath, Bexley, Greenwich, Charlton, Woolwich, Deptford, New Cross, Brockley, Forest Hill, Sydenham, Catford, Sidcup, Welling, Erith, Crayford, Abbey Wood and Thamesmead.
We also regularly assist clients around Southwark, Bermondsey, Peckham, Camberwell, Dulwich and nearby parts of Bromley where Southeast London neighbourhoods meet neighbouring boroughs.
If you already have architectural or structural drawings, it is worth checking the party wall position before contractors are booked to start. In many cases, a quick look at the foundation depth, structural arrangement and boundary position is enough to establish whether notices are likely to be needed.
We work throughout inner and outer Southeast London. The table below gives a practical overview of the principal areas, surrounding neighbourhoods and postcode districts we regularly cover.

Our work is not limited to the main town centres. We regularly assist with party wall matters in residential streets, conservation areas, suburban neighbourhoods and newer developments across the wider Southeast London region.
Southeast London is one of those parts of London where two projects only a few miles apart can look completely different. A Victorian terrace in Brockley may have a shared wall running from ground floor to roof level, making a loft conversion or chimney breast removal an obvious party wall consideration.
In Bexley, Sidcup or Welling, the same homeowner may instead be working with a semi-detached house with a side passage and a larger rear garden. The building work may not touch the neighbour’s wall at all, but new foundations could still be close enough to the adjoining property for the excavation provisions of the Act to become relevant.
Blackheath and Greenwich bring another mix altogether. There are period terraces, substantial older homes, converted flats, mansion-style properties and modern apartment schemes. Here, understanding exactly who the adjoining owner is can sometimes be as important as understanding the construction itself.
This is why we do not rely on a generic answer such as “extensions need a Party Wall Notice”. Some do and some do not. The answer depends on the position of the work, the type of structure involved, the boundary and, where excavation is proposed, the distance and depth in relation to the neighbouring foundations.

One of the reasons Southeast London produces such a range of party wall enquiries is the variety of its housing. Around New Cross, Deptford, Brockley, Peckham and Lewisham, properties often sit close together and extensions have to work within relatively tight plots.
Further out, there is often more physical space between houses, but that does not automatically remove the need for the Party Wall Act. A new foundation beside a semi-detached property in Bexley can still be close enough to a neighbour’s foundations to require notice, even if there is a visible gap between the buildings.
There are also many locations where old and new housing sit side by side. Greenwich Peninsula, Woolwich and parts of Lewisham have seen substantial redevelopment, while nearby streets may contain housing that is more than a century old. When a modern project sits next to an older structure, it is particularly useful to understand the adjoining property before construction starts.
We have dedicated pages for several Southeast London locations. Use the links below for more specific information about your area.
The location list above is deliberately broad, but Southeast London contains many smaller neighbourhoods and local names that overlap borough and postcode boundaries. If your street or area is not shown, it does not necessarily mean we do not cover it.
Send us your postcode, drawings or a brief description of the building work. We can check the location, review the proposed project and explain whether the Party Wall etc. Act 1996 is likely to apply.
