Why Early Feasibility Saves Time and Money on London Projects
The most expensive mistakes are made before design even begins — on untested assumptions about what a property can become.

Assumptions are expensive
Many London projects — and many property purchases — are decided on assumptions: that the loft can be converted, the basement dug, the rear extended, the flats combined. Some of those assumptions are sound; others run straight into a conservation-area control, an Article 4 direction, a lease restriction or a basement policy that quietly rules them out. The cost of discovering this late, after design fees or even a purchase, is far higher than the cost of checking first.
Feasibility turns assumption into evidence
A short feasibility study replaces optimism with evidence: the planning history, the designations, the constraints, and a realistic view of what the authority is likely to support. It tests a small number of options against those constraints and your objectives, and sets out the likely route and risks. For buyers especially, it can be the difference between a sound decision and an expensive one.
It shapes everything that follows
Because feasibility frames the whole project, getting it right early makes every later stage cheaper and faster. The design develops on solid ground, the planning strategy is clear, and the budget is set against what is actually achievable. It is usually the least expensive stage and the one with the greatest influence on the outcome.
