Pre-Purchase Renovation Feasibility in London

Before you buy a London property to refurbish, it pays to know what is realistically possible, what it will cost, and what could block it — while you can still negotiate or walk away.

A pre-purchase feasibility brings design, structural and surveying judgement together: what can be reconfigured or extended, the likely budget range, and the planning, conservation, leasehold and party-wall constraints that will shape the project.

We assess the property as a design-and-build team, with independent surveying support via Hampstead Chartered Surveyors, so your decision is based on realistic numbers and constraints rather than hope.

What a feasibility looks at

The condition and structure, what can be opened up or extended, planning and conservation-area limits, listed-building constraints, leasehold terms and likely Licence to Alter, party-wall exposure, and an honest budget range for the scope you have in mind.

Why it matters before you commit

The difference between a good and a poor purchase is often what you can do to it. A feasibility tells you whether your plans are achievable, what they cost, and where the risks are — before exchange, not after.

From feasibility to project

If you proceed, the feasibility becomes the basis of the design and a defined-scope fixed price. The same team carries it from assessment through approvals and into the build.

Keep purchase questions separate from a construction commitment

Use a brief to distinguish what you know about the property from what needs inspection, records or advice. Agree the feasibility appointment's scope, access and deliverables before relying on it for a purchase decision.

Information to gather

Record the property and tenure, available plans, survey information, intended changes, budget ceiling, occupation needs and purchase timing. Mark missing records and restricted access explicitly.

Questions to assign

List each unresolved structural, condition, approval, lease or cost question, who should answer it and what evidence they need. Do not treat a provisional allowance as a construction quotation.

Output to request

Ask for the options considered, constraints, assumptions, further investigations and dependencies to be recorded. Keep purchase, legal and finance advice with the advisers appointed for those decisions.
