A property feasibility study is an early assessment of whether a development project is worth doing. It brings together what you can create, what it will cost, what it will be worth, and what could go wrong and where the upside sits, then weighs it all up into a clear view of viability.
The output is a reasoned view on whether the project is viable, backed by numbers. Rather than a gut feel or a back-of-envelope estimate, you get a considered position on whether the project meets your target margin, on what assumptions and how that reads against your own risk profile. A back-of-the-envelope guess might tell you a site looks promising. A feasibility study tells you whether it holds up once land, construction, finance, professional fees and the likely sale values and risks and opportunities on either side model.
It informs a go or no-go decision rather than making one. A feasibility is one input into your wider due diligence, and where parts of it rest on assumptions rather than settled facts, the call comes down to your own risk profile, experience and industry connections as much as to the model. What it gives you is a reasoned position: how the project performs against your target margin, which assumptions that depend on, and what the risks and opportunities are on either side of it.
It is not a QS-style report with one definitive answer at the bottom. A good feasibility study gives you a range: the worst case, the best case, and how far the project can move before it stops working.


A structured assessment of whether a development project is viable, done before you commit. It combines market analysis, site analysis, cost estimation and financial modelling to test how the project performs against a target margin, what range the outcome could sit in, and where the risks and opportunities are. It informs the decision as part of your wider due diligence rather than replacing it.
Market analysis, site analysis, cost estimation, and financial modelling through gross realisation value, total development cost, developer's margin and residual land value, plus sensitivity and scenario testing. It is not a fixed list: the approvals pathway, the programme, the funding structure and the risks and opportunities specific to the site usually need to be in there too.
As a rough industry rule of thumb, developers and lenders have long looked for a developer's margin of around 20 per cent of cost or of gross realisation value. In practice, a 20 per cent margin is easy to produce on paper: nudge the sale rates up, the build cost down, and the programme in, and almost any site will show one. True 20 per cent margins are rare in the current market. The more useful questions are what the margin is on assumptions you can defend, whether it is genuinely achievable, and if it falls short, whether the site is still developable another way through staging, a different product mix, a design change or a lower land price. This is general information only.
It depends on the size and complexity of the project and the level of detail you need, so there is no flat rate. A preliminary feasibility on a straightforward site is a smaller exercise than a full study on a complex, multi-stage development. We scope it with you and confirm the cost before anything proceeds.
You can run a basic feasibility on a spreadsheet, and for a quick first pass, that is useful. The limitation is that a template only reflects the assumptions you put into it, and the hardest parts of a real project are judging achievable sale values, realistic yield after planning and true all-in costs. That is where an independent, market-grounded feasibility earns its place.
