CHECK 01
Start with an evidenced development scope
Keep a distinction between what is documented and what is proposed. A feasibility brief should make assumptions visible before they are used in an investment model.
- Record parcel identity, existing ownership and the planning documents available.
- Ask your architect to define the proposed use, areas, parking and required permissions.
- Reconcile gross floor area with the area expected to be sold or let.
CHECK 02
Make construction offers comparable
A single cost per square metre can hide major differences in scope. Keep the quantities, inclusions, exclusions and commercial terms with each offer.
- Request a bill of quantities or a clear scope schedule where available.
- Separate site preparation, building works, external works and utility connections.
- Record design fees, surveys, contingencies, taxes to confirm and payment terms.
CHECK 03
Connect programme and funding
The dates of acquisition, permissions, construction and sales influence how much capital a project needs. Prepare this sequence before relying on a headline return.
- Record milestones, dependencies and realistic allowances for outstanding approvals.
- List expected equity contributions, financing terms and major payment dates.
- Ask a financial adviser to test delays, cost increases and slower sales or letting.
CHECK 04
Keep the investment decision traceable
Use one project file to connect the brief with documents and assumptions. Record what would change the decision, and the work needed before a bid or construction commitment.
- Record each sales-price or rental assumption with its source and date.
- Separate the target return from a calculated and independently reviewed result.
- Assign outstanding legal, architectural, cost and financial reviews to the appropriate advisers.
