The asking price may look attractive. The proposed floor plans may look convincing. The development may still depend on several optimistic assumptions happening together.
Before committing to a site, ask what happens when one of those assumptions changes. This is where an early feasibility review earns its place in the buying process.
Begin with a scheme the site could support
A sketch showing the maximum possible floor area is a starting point, not evidence that every square metre can be approved, built or sold at your target price.
Planning policy, neighbouring buildings, access, daylight, servicing and the existing structure may constrain the design. Some sites also require specialist investigations into matters such as drainage, ground conditions or heritage.
Commission proportionate due diligence. Ask the relevant advisers to distinguish established facts from assumptions that remain to be tested.
Examine three kinds of pressure
First, test cost. Ask your cost adviser what happens if an unresolved construction item is more expensive than allowed for. The useful exercise is tied to real risks in the scheme, rather than an arbitrary adjustment made to every project.
Second, test value. A local agent or valuer can help examine the evidence behind the expected sale or rental figures. Asking prices and achieved prices are different things. A larger scheme does not automatically produce a better return.
Third, test time. A longer programme may affect borrowing costs, overheads and the date you receive income. Check the consequences with your finance adviser using the actual proposed terms.
Test combinations as well as individual changes
A construction delay and slower sales can happen together. Looking at each in isolation may understate the exposure.
Have your advisers prepare realistic alternative scenarios and explain what drives them. Keep the original assumptions visible so you can understand why the outcome changes.
The objective is to identify how much room the project has before it stops meeting your requirements. It is not to produce a spreadsheet that always ends with the answer you hoped for.
Use the findings to make a decision
An early review may support proceeding. It may also suggest a revised purchase offer, further investigation, a different design or walking away.
For example, reconsidering the arrangement of units could alter circulation, structural work and servicing. Whether that improves the commercial result needs a fresh cost and value assessment. Design changes should be tested, not celebrated as savings before anyone prices them.
Horizon Architecture can help you investigate architectural potential and constraints within an agreed feasibility scope. Your valuer, cost adviser, solicitor and finance adviser provide the specialist advice needed for the acquisition decision.
Send Horizon the site address and your intended development brief to discuss an architectural feasibility review before you commit.
