Commercial & Mixed-Use Party Wall Surveys in London

Hourican Associates provides specialist Party Wall surveys and neighbourly matters advice for commercial and mixed-use developments across London. Our Chartered Party Wall Surveyors support developers, investors and professional teams with legally compliant party wall survey commercial development services and pragmatic developer party wall advice from concept design through to practical completion.

Specialist Party Wall Surveys for Commercial & Mixed-Use Schemes

Larger-scale developments bring more complex Party Wall and neighbourly matters. Multi-storey commercial buildings, mixed-use blocks, basement car parks and podium structures often involve deep foundations, boundary works, crane oversailing and significant temporary works — all of which can impact neighbouring properties.

Our team acts for developers, housing associations, institutional landlords and professional project teams, delivering robust Party Wall strategies that keep schemes compliant, buildable and neighbourly. We combine technical building expertise with clear commercial thinking to minimise risk and avoid costly programme delays.

When You Need Party Wall Advice on Commercial Developments

You should seek early developer party wall advice whenever your commercial or mixed-use project involves:

  • New-build commercial or mixed-use blocks constructed on or close to the site boundary.
  • Basement car parks, deep foundations, piling or contiguous piled walls adjacent to existing structures (see also our Party Wall survey for excavations).
  • Extensions, rooftop additions or change of use works impacting shared or party structures, captured under Party Structure surveys.
  • Rationalisation or demolition of existing commercial units within terraced or infill sites where boundary and ownership lines are critical.
  • Phased regeneration schemes where construction will interface with retained or occupied neighbouring buildings.

Early engagement allows us to identify all affected adjoining owners, advise on risk, and structure a Party Wall strategy that aligns with planning, design and procurement milestones.

How Our Commercial & Mixed-Use Party Wall Service Works

Our commercial Party Wall service is designed to integrate seamlessly with your wider development programme and professional team.

  1. Initial Appraisal & Strategy
    We review title plans, survey information and proposed layouts to map Party Wall risks, identify relevant adjoining owners and confirm which sections of the Party Wall etc. Act 1996 apply. At this stage we provide high-level developer party wall advice on sequencing, procurement and risk allocation.
  2. Serving Party Wall Notices
    We prepare and serve all necessary Party Wall Notices (Section 1, 2 and 6) on freeholders, leaseholders and relevant stakeholders. Notices are fully referenced to your structural designs and issued with clear explanatory material to promote early engagement and consent where appropriate.
  3. Surveyor Appointments & Neighbourly Liaison
    We act as Building Owner’s Surveyor, liaising with any Adjoining Owners’ Surveyors or, where suitable, as a neutral Agreed Surveyor. We manage expectations, clarify construction proposals and maintain positive relationships with neighbours and their advisors.
  4. Schedules of Condition & Technical Review
    Our team carries out detailed Schedules of Condition of adjoining properties — including enhanced basement condition surveys where necessary. We review structural and temporary works designs to ensure risks are properly understood and controlled.
  5. Party Wall Awards & Ongoing Oversight
    We prepare and agree comprehensive Party Wall Awards setting out access, protection measures, monitoring regimes, working hours and damage resolution procedures. Where needed, we undertake site inspections, monitoring and deal with any issues under Party Wall dispute resolution provisions.

Throughout, we coordinate closely with your project manager, design team and legal advisers to keep Party Wall processes aligned with site start dates and key programme milestones.

Transparent Fees for Commercial Party Wall Surveys

Fees for commercial and mixed-use Party Wall surveys are typically agreed on a bespoke, fixed-fee or hourly basis depending on the scale and complexity of the development, the number of adjoining owners and the anticipated level of negotiation and site involvement.

As a guide, individual Party Wall Awards for smaller commercial refurbishments may be comparable to our residential fee range of £1,100 – £1,500 + VAT per Award, while larger multi-owner or phased developments are priced following an initial review of your drawings and title information. All terms are agreed in advance, with clear scopes and no hidden extras.

Commercial & Mixed-Use Party Wall – FAQs

Yes. The Party Wall etc. Act 1996 applies to commercial, mixed-use and residential schemes alike. If your works involve building on a boundary, altering a party structure, or excavating near neighbouring foundations, you will usually need to serve Party Wall Notices and agree Party Wall Awards, regardless of the building’s use.

As early as possible. Ideally, we should be involved at RIBA Stage 2–3 so we can advise on risk, identify adjoining owners and ensure your programme allows enough time for Notices, negotiations and Party Wall Awards. Late involvement increases the risk of site start delays and urgent, reactive negotiations with neighbours.

In most cases, the Building Owner (the developer or landlord carrying out the works) is responsible for the reasonable fees of all appointed Party Wall Surveyors, including those acting for adjoining owners. We can provide fee forecasts to help you build Party Wall costs into your development appraisal.

Yes. We regularly act on complex schemes where issues arise during construction. Our role includes investigating alleged damage, comparing it against the original Schedule of Condition, and resolving matters under the Party Wall dispute resolution procedure. Where necessary, we issue supplemental Awards dealing with repairs, compensation and ongoing monitoring.

Absolutely. Many mixed-use and regeneration schemes are phased or split across several titles and landowners. We can develop a phased Party Wall strategy, coordinate Notices and Awards across multiple parcels, and remain involved throughout the life of the project to ensure continuity of advice and documentation.
