What actually moves the number: scope depth, wet rooms, MEP condition, joinery and approvals — and how to read a BOQ so two quotes can be compared honestly.
Two villas of the same size in the same community can differ in renovation cost by a multiple. Not by a percentage, by a multiple.
That is why per-square-foot figures published on contractor websites are close to useless. They are averages across projects that had nothing in common, and quoting one back at a contractor will not get you a better price.
What is useful is understanding what actually moves the number, so that when quotations arrive you can tell which one is cheaper and which one has simply left things out.
A bill of quantities you can read line by line, not a single figure.
A BOQ worth comparing shows scope broken down room by room, materials named by specification rather than category, quantities and rates, exclusions stated explicitly, who is responsible for approvals and drawings, and payment milestones tied to completed stages.
Provisional sums are worth understanding too. Where a cost cannot be fixed at quotation stage, because the tile has not been chosen or the extent of a repair is unknown, a contractor includes an allowance. That is legitimate. What matters is that provisional sums are labelled as such, and that you know what happens when the actual cost differs.
Yes, and they are commonly left out of the number people budget for.
Where a villa project involves structural work or an extension, there are drawings to be prepared, a consultant or engineer to be appointed, and submission and permit costs to be paid. Developer and community NOC processes may carry their own fees.
None of this is optional, and none of it is large relative to the build cost. What causes problems is discovering it after the budget is set, because it was not in the quotation and nobody mentioned it.
Ask which approvals apply to your villa, who submits each one, and what the associated costs are, at quotation stage rather than later.
From a site visit and a scope, never from a phone call and an area. What to ask for on every quotation:
Time affects cost, because a longer programme carries more preliminaries.
Approvals come first and run on the authority's timetable. After that, the sequence is strip-out, civil works, MEP first fix, waterproofing, screed, finishing and second fix, with joinery manufactured in parallel.
Two things stretch programmes and therefore budgets: imported materials with long lead times, and scope changes made after work has started. A tile changed at design stage costs nothing. The same tile changed after screeding costs weeks and a variation.
A quotation with no provisional sums on a villa project is either extremely well defined or quietly optimistic.
Send us the community, plot size and what you want to change. We will visit the villa, confirm which approvals apply, and issue a bill of quantities with materials, exclusions and provisional sums stated.
