Architects, Engineers, Surveyors & Builders Under One Roof.
Surveyor-led refurbishment advice via Hampstead Chartered Surveyors →One Studio. One Contract. One Team.
We deliver Swiss Cottage structural engineering with architects, engineers, surveyors and builders under one fixed-price contract - design, technical coordination, procurement, directly managed site teams, Building Control, programme control and final handover through one accountable team.
Every structural works project in Swiss Cottage is designed to respect the Swiss Cottage Conservation Area and the character of Italianate Victorian villas, period conversions, mansion blocks. Our in-house RIBA architects handle Camden planning applications, our chartered structural engineers specify any load-bearing work, and our directly-employed trades deliver the build under one fixed-price contract. We coordinate Building Control, Party Wall awards where needed, and all certifications through to handover.
Period properties in Swiss Cottage often require structural work to open up layouts, support extensions or address subsidence. Our engineers understand the specific structural systems used in victorian terraces, mansion blocks, post-war estates, converted period houses and modern apartments and design solutions that respect original construction methods.
Well-connected north London area around the iconic Swiss Cottage pub. Mix of period properties and post-war developments with excellent transport links and the Hampstead Theatre.
Basement proposals around Swiss Cottage are assessed under Camden Local Plan 2017 Policy A5, which places specific restrictions on the scale of basements and their impact; a site-specific Basement Impact Assessment covering drainage, flooding, groundwater conditions and structural stability must be submitted, and Camden Planning Guidance: Basements was formally adopted on 26 March 2018. Basement conversion (existing cellar) — London-wide rate guidance: Conversion of existing space: £750–£3,000/m² (total converted area); fully finished can exceed £6,000/m² (Ideal Home, Sept 2025).

Structural engineering is the discipline that decides whether a wall can come out, how a new storey is carried and what keeps a basement dry and standing. Because our chartered structural engineers work in the same studio as our architects, the structure is resolved while the layout is still being drawn — not retro-fitted to a finished design. Typical commissions include the work below.
Six stages from first enquiry to a structure signed off on site, whether we engineer alone or design and build the whole scheme.

Every structural alteration must satisfy Part A of the Building Regulations, and building control will not sign the work off without calculations that prove the new load paths — which is why we produce a complete, checkable package rather than a beam size scribbled on a quote. Where a new steel bears on a wall you share with a neighbour, party wall notice is normally required before installation. Our planning guide library explains the approval routes in your borough.
Most renovation firms buy their engineering in from external consultancies; we keep it in the building. Our own chartered structural engineers sit alongside our in-house RIBA Chartered Architects, so structure and design are agreed in the same meeting rather than posted between offices, and RICS surveying support is available through our sister company, Hampstead Chartered Surveyors, when party wall or condition questions arise. The practice carries £10M public liability cover, works on fixed prices rather than open-ended fees, and stands behind built work with a 12-month defects period and a 10-year workmanship warranty. Enquire before 2pm on a weekday and we will call you back the same day.
Structural Engineering in Swiss Cottage typically costs £450–£800/sqm. The final price depends on the scope, specification and complexity of the project. We provide a detailed fixed-price quotation after the initial consultation and design phase.
Whether planning permission is required in Swiss Cottage depends on the scope of work. Our team assesses planning requirements at the initial consultation and manages all necessary applications.
Structural Engineering projects in Swiss Cottage typically take 2-6 weeks. Including design and any planning approvals, the total programme depends on project complexity. We provide a detailed timeline at the consultation stage.
