Grey & Associates are party wall surveyors covering East London — Hackney, Tower Hamlets, Newham, Waltham Forest, Redbridge, Barking & Dagenham and Havering. East London is where conversion does most of the work. The Victorian and Edwardian terraces of Hackney, Walthamstow and Leytonstone have been divided into flats on a scale no other part of London matches, which means the party structure usually touches several demises at once and the first question on any project is how many adjoining owners there are. In Tower Hamlets the same terraces sit beside warehouse conversions and residential blocks where the party structure is a separating floor or a frame rather than a brick wall, and to the east the regeneration of Stratford, the Royal Docks and Barking Riverside has put new build up against old boundaries. We act for the owner building and for the neighbour who has received the notice.

Key takeaway

Three things drive most East London party wall cases. Sub-divided terraces, where one house can contain several adjoining owners and the count decides both the fee and the timetable. Party structures that are not walls — separating floors and structural frames in converted warehouses and blocks, which the Act covers just as it covers a wall. And rebuilding and regeneration, where a new structure on or near the boundary engages section 6 as well as section 1, and the neighbour's foundations are often shallower than the drawings assume.

If a notice has arrived and you own a leasehold flat rather than the freehold, you are still an adjoining owner in respect of your own demise — and in a dispute the Building Owner pays the reasonable fees of both sides' surveyors.

Borough by borough: what changes about the work

The Act applies identically in all seven boroughs. What differs is the housing, how much of it has been converted, and how much of it is being rebuilt.

Hackney — E2 Shoreditch and Hoxton, E5 Clapton, E8 Hackney and London Fields, E9 Homerton, N1 and N16 Stoke Newington and Dalston

Hackney is terraces and conversion. The Victorian housing across Hackney, Dalston, Stoke Newington, Clapton and London Fields has been sub-divided very heavily, so a project in one house frequently has several adjoining owners to serve, each entitled to their own surveyor and their own award if the case is in dispute. Rear and side extensions run into shallow gardens where the boundary wall is close, and new foundations frequently land within three metres of a structure older and shallower than the drawings allowed for — which is section 6 work as well as section 2 where the party wall itself is altered. Around Shoreditch and Hoxton the stock changes to warehouse and commercial conversions, where the party structure is more likely to be a floor, a frame or a shared service riser than a brick wall, and where the adjoining owner is often a company rather than an individual.

Tower Hamlets — E1 Whitechapel and Spitalfields, E2 Bethnal Green, E3 Bow and Mile End, E14 the Isle of Dogs and Poplar

Tower Hamlets has the starkest contrast in the region: nineteenth-century terraces in Bow, Bethnal Green and Mile End at one end, and high-rise residential blocks on the Isle of Dogs at the other. In the terraces the case follows the Hackney pattern — sub-divided houses, multiple adjoining owners, extensions reaching the boundary. In the blocks the question is different. Works to a separating floor, to a structural frame or to common parts engage the Act as party structure work, and the freeholder or management company is usually an adjoining owner alongside any leaseholder whose flat touches the work. Where a development abuts an existing building, the excavation for it is section 6 work in the ordinary way, and the Schedule of Condition on the older structure is the evidence that matters later.

Newham — E6 East Ham, E7 Forest Gate, E12 Manor Park, E13 Plaistow, E15 Stratford, E16 Canning Town and the Royal Docks

Newham is the borough where regeneration and older housing meet. Stratford, Forest Gate and Manor Park have substantial Victorian and Edwardian terraces, much of it converted and much of it extended to the rear, on the same pattern as Waltham Forest. Alongside that, the Royal Docks, Canning Town and Stratford have seen large-scale new build and the conversion of commercial buildings into flats, where party structures are modern and the adjoining owners are frequently institutional. For a surveyor the practical difference is that on new-build boundaries the structure is well documented and the risk sits in the excavation and the sequencing; on the Victorian terraces it sits in the condition of a wall that was never designed for what is now being done to it.

Waltham Forest — E10 Leyton, E11 Leytonstone, E17 Walthamstow

Waltham Forest is the densest concentration of Victorian and Edwardian terraces in East London, and the most heavily sub-divided. A typical project — a loft conversion, a rear extension, a side return or an internal reconfiguration to create another flat — will usually involve the party wall, often in more than one place, and often with three or four adjoining owners across two converted houses. Loft work here raises the section 2 questions directly: cutting a steel into the wall, forming a gable on the boundary or removing a shared chimney breast are all notifiable, and the two-month notice period is the part of the programme that gets missed. Party fence walls between gardens are separate again, and work to one is notifiable in its own right.

Redbridge — E18 South Woodford, IG1 to IG4 Ilford, IG8 Woodford Green

Redbridge mixes Victorian and Edwardian houses in and around Wanstead and South Woodford with the 1930s semi-detached and detached housing that dominates Woodford Green and much of Ilford. The inter-war houses behave like their counterparts in Barnet and Enfield: a party wall running the full depth of the building, long rear gardens, and projects — extensions, lofts, chimney breast removal — that touch the wall at one point or another. Cases here are usually one neighbour and one notice, which is why they sit comfortably on the fixed fee. Larger plots and infill development bring in section 6 where a new building goes below the level of the neighbouring foundations.

Barking & Dagenham and Havering — IG11 Barking, RM8 to RM10 Dagenham, RM1 and RM2 Romford, RM11 to RM14 Hornchurch and Upminster

The two easternmost boroughs are dominated by inter-war and post-war semi-detached and terraced housing, with a much higher proportion of owner-occupied freehold houses than the inner boroughs and far less sub-division. That produces the most straightforward party wall work in the region: a rear extension or loft conversion on a semi, one adjoining owner, one notice, a Schedule of Condition and an award on the fixed fee. The exception is the regeneration corridor — Barking Riverside and the areas around it — where new development abuts existing housing and the excavation, rather than the party wall itself, is the risk. In Havering the larger detached and semi-detached houses around Upminster and Hornchurch are more often extended on both floors at once, which brings the roof structure and the party wall into the same scheme.

What East London cases turn on

  • Counting the adjoining owners is the first job. In Hackney, Waltham Forest and the terraced parts of Newham a single house may contain several flats, each a separate interest, with the freeholder or management company as another. Notices go to owners, not tenants. Getting the count wrong at the start is the most common avoidable delay in the region.
  • A party structure is not always a wall. In warehouse conversions and residential blocks, the separating floors and the structural frame are party structures under the Act. Works to a floor — new openings, strengthening, sound insulation — can be notifiable even where no wall is touched, which surprises owners who assumed the Act only concerned brickwork.
  • Loft conversions on terraces are notifiable more often than people expect. Cutting a steel into the party wall, forming a gable on the boundary or removing a shared chimney breast is section 2 work with a two-month notice period. A scheme that stays clear of the wall may fall outside the Act, but the answer depends on the drawings.
  • Depth decides the section. Excavating within three metres of a neighbouring structure and deeper than its foundations is section 6, as is excavation within six metres in the wider case the Act describes. On the Victorian terraces of Waltham Forest and Hackney the neighbour's footings are frequently shallower than the drawings assume, so the three-metre test is met sooner than expected.
  • Access is a separate permission. Scaffold over a neighbour's garden, a crane over their roof, or a skip on their forecourt needs their agreement and, if they refuse, an application under separate legislation. The party wall award governs the notifiable work; it does not hand you the neighbour's land.

For the framework, the Party Wall Act explained and what counts as a party wall cover the ground. Section 1 deals with new walls on the boundary and installing a steel beam into a party wall covers the most common structural trigger in East London conversions. If a neighbour has gone quiet, what happens when a neighbour ignores a party wall notice sets out the position.

Fees across East London

Fixed and published, and the same in every borough: £165 + VAT per adjoining property to serve notice, £620 + VAT per Schedule of Condition, and £350 + VAT per adjoining property for an award acting for the Building Owner. A one-neighbour dispute — notices, one Schedule of Condition and the award — is £1,135 + VAT. All prices exclude VAT at 20%.

Basement and underpinning works are priced differently. A basement under a Hackney or Tower Hamlets terrace involves deeper excavation, more engineering input and a far more extensive schedule than a loft conversion, and it is not priced as one. We review your plans and the proposed works first, then present a formal written quote before anything is agreed or any notice is served. How we run those schemes — section 6, temporary works, monitoring and the Schedule of Condition — is set out on our basement and underpinning party wall surveyors page.

The full breakdown, including the statutory position on who pays for both sides' surveyors, is on our London party wall surveyor page.

East London party wall questions

Do I need a party wall award to convert a Victorian terrace in Hackney or Walthamstow into flats?

It depends on what the conversion does to the party structures. Creating new flats normally involves work to the separating floors between levels and, on a house attached to its neighbour, to the party wall itself — cutting in for steels, forming new openings or altering a shared chimney breast. Work to an existing party wall, including the floors that separate the two buildings, is section 2 work under the Act and is notifiable. A conversion that only changes a flat internally, without touching the party structure, is not.

I have received a notice about work in a neighbouring flat in Tower Hamlets. What are my options?

You can consent, and the matter goes no further. You can dissent, in which case the Act provides for a surveyor to act for you, and in a dispute the Building Owner pays the reasonable fees of both sides' surveyors. Or you can do nothing, and after fourteen days you are treated as having dissented. Silence produces the same legal result as dissenting, but a fortnight later and without any say in who is appointed to act for you.

The house next door in Waltham Forest is being extended right up to the boundary. What notice should have been served?

Where a new wall is built on the boundary line, or the new structure abuts the boundary and its foundations go below the level of yours, a section 1 notice is required and carries one month's notice. Where the excavation is within three metres of your structure and deeper than its foundations — or within six metres in the wider case the Act describes — section 6 applies instead. On a rear or side extension the two often overlap, and the notice should describe the work accurately enough that it is clear which provision is being relied on.

What does a party wall surveyor cost in East London?

Fixed fees across East London: £165 per adjoining property to serve notice, £620 per Schedule of Condition, and £350 per adjoining property for an award acting for the Building Owner. A one-neighbour dispute — notices, one Schedule of Condition and the award — is £1,135 all-in. All figures exclude VAT at 20%. Basement and underpinning works are priced differently, and a formal quote follows a review of the plans and proposed works.
