A clear sequence helps a renovation team coordinate surveys, approvals, opening-up work, installations and finishes. This guide sets out useful stage gates while leaving the final programme to the inspected property, agreed scope and appointed team.
Identifying which walls are load-bearing
For a period property, assess how each option interfaces with retained fabric and modern performance requirements. The preferred solution should be supported by the survey, design brief and any address-specific authority advice.
The right choice depends on the inspected property, intended use and verified planning context. If heritage controls apply to the exact address, compare options against the current official guidance rather than assuming an aesthetic preference will be acceptable.
Structural survey and engineer appointment
The practical test for structural survey and engineer appointment is whether it reduces uncertainty before work begins. Good preparation creates a written scope, identifies the approvals or evidence to verify, and makes clear who is responsible for each step before walls, floors or shared services are opened up.
For this guide topic, the structural survey and engineer appointment stage should be judged against the property itself rather than a generic national checklist. In NW London, construction, access, leasehold terms, verified designations and previous work can change the appropriate route. Confirm those points before quotes are compared or materials are ordered.
RSJ beam sizing and specification
For this guide topic, the rsj beam sizing and specification stage should be judged against the property itself rather than a generic national checklist. In NW London, construction, access, leasehold terms, verified designations and previous work can change the appropriate route. Confirm those points before quotes are compared or materials are ordered.
When reviewing rsj beam sizing and specification, ask for advice that is specific to the building and exact address. A useful proposal explains what has been inspected, what remains an assumption, and which parts of the work could affect cost, programme or compliance. That clarity is important for builder and structural engineer in any period home.
Building Regulations and notifications
When reviewing building regulations and notifications, ask for advice that is specific to the building and exact address. A useful proposal explains what has been inspected, what remains an assumption, and which parts of the work could affect cost, programme or compliance. That clarity is important for builder and structural engineer in any period home.

The removal process — sequence and sequence
Trade coordination should make interfaces explicit: service routes, pressure or functional tests, substrate readiness, protection and final tolerances. Capture those decisions in the programme and written scope rather than relying on informal assumptions.
Sequence wet work, services, closing-up, joinery and finishes around the actual design and drying or inspection dependencies. Record who can authorise progression so one trade does not conceal work that still needs checking.
Temporary propping
When reviewing temporary propping, ask for advice that is specific to the building and exact address. A useful proposal explains what has been inspected, what remains an assumption, and which parts of the work could affect cost, programme or compliance. That clarity is important for builder and structural engineer in any period home.

Finishes and making good
For this guide topic, the finishes and making good stage should be judged against the property itself rather than a generic national checklist. In NW London, construction, access, leasehold terms, verified designations and previous work can change the appropriate route. Confirm those points before quotes are compared or materials are ordered.

Extension to maximise space
For this guide topic, the extension to maximise space stage should be judged against the property itself rather than a generic national checklist. In NW London, construction, access, leasehold terms, verified designations and previous work can change the appropriate route. Confirm those points before quotes are compared or materials are ordered.

Cost breakdown
Costs in NW London vary materially by scope, condition, access, specification and specialist requirements. National or regional guides can provide context, but they should not be converted into a project budget without current, like-for-like written quotes.
A contingency should reflect the survey information, design maturity and risk of concealed conditions rather than a universal percentage. Agree how discoveries and changes will be assessed, priced and authorised before opening up work begins.
