Measured from your drawings and priced by our suppliers, weeks before technical design and tender stage. Your biggest design decisions are informed and backed by numbers you can trust. arko is the room you walk into before either of those begin
Your budget starts life as an estimate and nothing tests it for months. By tender, the market has shifted, the drawings are finished and the fees are spent. The only lever left is to scale back the vision. arko is here to bridge that gap so what you design is what you build.
A 45 m² rear extension in Edinburgh. On the left, the figure as it is normally given. On the right, the same project measured and priced by arko. Real prices, each with the date it was given and how long it stands. Allowing you to design what you can actually build.
Illustrative extract. The method is real and so are the hold periods. The figures are a worked example. The full trade list and what each tier covers are on What you get.
Quantities and spec derived from architect’s drawings. Priced by named suppliers who work with us to provide a price hold at design stage. Any allowances are clearly labelled. And every price carries a date, so you can make clear and informed decisions based not only on visuals but on the numbers behind them.
Numbers that you can trust and act upon later at tender stage.
From £1,800. Four questions, then we ask for the drawings you already have.
A QS prices from rates, which is historic data about projects like yours.
We price from the firms who would actually supply yours, with a date on every figure.
We asked eleven suppliers at the Edinburgh show. Holds ran from thirty days to twelve months.
Being in the specification is how a manufacturer wins work, and by tender that is already decided.
No. We tell you who will, and for how long.
Every figure carries the supplier’s name, the date and the hold they stated. Anything past that window is flagged for rechecking, not carried forward.
Eleven conversations with UK manufacturers, merchants and installers at the Homebuilding & Renovating Show, Edinburgh, October 2026. Hold periods are what each supplier told us, not a quotation from arko.
You engage us directly and you pay us directly. Never for what we specify. No commission, no placement fee, and no supplier pays us anything at any stage. If a supplier’s price is wrong for your project, we say so in writing.
Architects and manufacturers have reason to want this too. The manufacturer gets specified rather than substituted. The architect gets a client who can say yes to the design. If that is you, write to info@arko.build.
Tell us about the project and we come back within two working days.
