An indicative range of what your project costs. Not a quote and not an offer: the starting point for knowing whether the project stands up before spending on it.

Indicative breakdown by chapter
The figures are indicative estimates based on market parameters and cross-checked against projects we have delivered. They do not constitute a contractual offer. The real cost depends on the condition of the property, the technical solution, the specific quality of materials, location and market conditions. Excludes professional fees, permits, taxes, loose furniture and VAT.
Reference prices
These are the ranges the calculator above applies to a full residential refurbishment at flat-sized areas. They are construction cost, excluding VAT: what the works cost once the design is settled and the packages are contracted. Within the range, what moves the figure is the starting condition of the property and the finish you choose.
What that figure does not cover
Almost every overrun on a refurbishment comes from this list rather than from the rate per square metre. Settle these before you compare quotes.
How to read this number
Anyone can give you a price per square metre in ten seconds. The hard part, and what decides whether your project ends up on budget, is what sits underneath that figure.
This calculator is for ruling things out quickly: for knowing whether the order of magnitude fits what you plan to invest, before commissioning a design. That is what it is for, and it is worth a lot.
What it cannot do is replace the preliminary analysis. The budget that holds until the end comes from reviewing the project item by item, checking prices against real quotes from trades and ordering the construction sequence. That is pre-construction, and it is where we concentrate 60% of our effort.
