Most development mistakes are made before the first drawing. A landowner commissions a design for the project they imagine, the numbers are worked backwards to fit it, and only later does it emerge that the market wanted something else, or that the regulations allowed something better. Highest and best use is the discipline of asking the questions in the right order.
Four tests, in order
A use is the highest and best use of a parcel only if it passes all four of these, and the order matters.
- Legally permissible. What the zone allows, under the development regulations that apply to it. In Gujarat that means the comprehensive GDCR and the development plan for the area: the uses permitted in the zone, the FSI, the height, the margins and the parking that must be provided.
- Physically possible. What the site itself allows. Its size and shape, its frontage and access, the width of the road it faces, the ground conditions and the services that can reach it.
- Financially feasible. Which of the remaining uses produce a value greater than the cost of creating them, including the land and a fair return for the risk.
- Maximally productive. Of the uses that pass the first three tests, the one that gives the land the highest value.
What the site plan shows
The site plan at the top of our home page runs the first two tests in miniature. Move a corner and the frontage, the depth and the buildable envelope inside the margins change at once, and with them the built-up area the regulations permit. Two plots of the same area can carry very different buildings once their shape and their road are taken into account.
The test that is usually skipped
The third and fourth tests need evidence from the market rather than from the drawing board: what sells in that location, at what size, at what price and how quickly. This is where demand assessment and financial feasibility do their work. A residential tower may be legally permitted and physically possible on a site where the market will only absorb mid-rise apartments at a pace that makes the tower's financing cost unbearable. The answer is not the largest building the land allows. It is the use that leaves the land worth the most.
Why it is worth doing first
An assessment of highest and best use costs a small fraction of a design fee and changes the brief the designer works to. For a landowner it also changes the negotiation: a parcel offered to a developer with its best use already established is a stronger proposition than one offered with a guess.
If you hold land and are deciding what to do with it, tell us about the parcel and the decision in front of you.
