Christopher Anthony Surveyors provide specialist party wall surveying across North London, acting for homeowners, landlords, developers, and architects from our base in Hackney. We cover every North London borough — Islington, Camden, Haringey, Barnet, Enfield and beyond.
North London's dense streets of Victorian and Edwardian terraces make party wall matters a regular part of almost any extension, loft conversion or basement project. We handle these every day, and we understand the particular challenges that come with older shared walls, narrow plots, and closely spaced properties.
North London's housing stock presents specific party wall considerations that a surveyor without local experience can miss. Older party walls in areas like Highbury, Stoke Newington, Crouch End and Muswell Hill are often in varying condition — and a thorough schedule of condition before works begin can protect both your client and their neighbours from costly disputes later.
We have direct experience across all North London boroughs and understand the types of projects commonly undertaken in this area — rear extensions to Victorian terraces, loft conversions on Edwardian semis, basement digs beneath period properties, and side return extensions on narrow plots.
Loft Conversion — Islington
We acted as Agreed Surveyor for a client in Islington carrying out a loft conversion to a mid-terrace Victorian property. Two party walls were affected, involving neighbours on both sides. Both awards were agreed within four weeks, allowing works to start on programme. The schedule of condition documented significant pre-existing cracking to one neighbouring property, protecting our client from any future claim.
Rear Extension — Crouch End, Haringey
We were instructed as Building Owner Surveyor for a rear extension to an Edwardian semi-detached in Crouch End. The project involved one adjoining owner who initially had concerns about the depth of the new foundations. We arranged a joint site meeting, explained the proposed method of working, and the award was agreed within three weeks without the need for a separate surveyor to be appointed.
Basement Works — Camden
We acted for a developer carrying out basement excavation works beneath a period property in Camden, with two neighbouring properties affected. Given the complexity of the works, we carried out thorough schedules of condition to both properties and agreed a detailed party wall award setting out monitoring requirements during the excavation phase. Both awards were in place within five weeks of instruction.

In most cases, yes — if your loft conversion involves cutting into the party wall to insert steel beams, raising the party wall, or working within 3 to 6 metres of a neighbouring property's foundations, the Party Wall etc. Act 1996 will apply. We can confirm this quickly after reviewing your drawings.
Once served, adjoining owners have 14 days to respond. If they consent, works can proceed once the notice period expires. If they dissent or don't respond, surveyors are appointed and an award is agreed — typically within 3 to 5 weeks for standard residential projects in North London.
In most cases, the building owner (the person carrying out the works) is responsible for paying the party wall surveyor fees for both parties. This is a legal requirement under the Act, not a commercial arrangement.
Yes. We understand that programme pressure is real. We can issue notices within 2 to 3 working days of instruction and will prioritise communication to keep your project moving. Call us directly on 020 3727 5195 to discuss urgent instructions.
