PLAIN-ENGLISH PROJECT GUIDES
Is this property still worth buying once the works are included?
Test the purchase and the proposed works together, with clear uncertainty rather than one optimistic total.
Separate a good building from a workable project
An attractive purchase price does not establish that your intended scheme is affordable. Consider acquisition, works, professional input, holding costs and the time before the property can be used. Your solicitor, surveyor, valuer and funding adviser cover different parts of that decision.
Check the proposal before relying on it
Do not assume a conversion, extension or change of use will be acceptable. Ask the relevant specialists to investigate the planning position, access, condition and essential services. A broad cost exercise cannot establish legal rights, structural safety or consent.
Test an uncomfortable version
Compare a baseline with a slower programme, higher works allowance or reduced usable space. Record which assumptions make the decision change. If the scheme only works when every assumption is favourable, that is useful information before commitment.
Choose the next decision
A review might support further investigation, a smaller scheme, negotiation or no purchase. It cannot promise a return or replace a professional valuation. Write down the information still needed and avoid treating a preliminary result as purchase approval.
Your practical checklist
- Define the intended use and approximate area.
- Obtain appropriate survey and legal advice.
- Test costs and timing together.
- Set a decision point before committing further money.
