Enormous Buildings is an AI-driven take-off engine for construction. You upload the dimensioned drawings you'd hand to a quantity surveyor; we return the same trade-by-trade, line-item takeoff a QS would produce — priced in your local currency, against current regional unit rates, with the source of every rate attached.
The platform is built for architects, developers, contractors and self-builders who need a defensible budget number early — for feasibility, value-engineering, pre-tender estimates or simply sanity-checking a contractor's quote — without waiting weeks for a manual take-off.
Four steps, drawing to priced takeoff
Upload drawings
Drag in dimensioned PDFs, PNGs or JPGs (up to 25 MB each). Multiple sheets — plans, elevations, sections — are welcome.
Configure project
Pick your country and currency, an address (optional), pricing tier and any specific materials you want priced.
Analyse & price
The engine extracts quantities trade-by-trade, applies current regional unit rates, and assembles a full Quantity takeoff.
Download takeoff
Receive a priced, source-cited takeoff — viewable in-app, exportable to PDF, and saved to your account for re-download.
Built like a quantity surveyor would
Quantities from drawings
Upload dimensioned floor plans and elevations. The engine reads each sheet, infers room areas, wall lengths and openings, and turns them into priced line items.
Regional unit rates
Material and labour rates priced for the country you specify, in your local currency. Every unit price is returned with a source — vendor, handbook, or regional rate survey.
Three pricing tiers
Compare a Low-cost, Standard or Luxury specification on the same drawing set. Useful for value-engineering before you commit to a contractor.
Industry-standard templates
CSI MasterFormat for North America, NRM2 for the UK and Ireland, and a generic metric template for everywhere else. Output suits both owners and QSs.
Minutes, not weeks
A typical analysis completes in two to five minutes. Compare with the days or weeks a manual take-off takes, and the result lands directly in your account.
Auditable output
Every quantity is grouped by trade and every rate is sourced. You can hand the takeoff to a contractor or QS and they'll see exactly where each number came from.
The right template for your jurisdiction.
The engine selects an industry-standard takeoff template based on the country you choose, and prices the quantities in the local currency you select. Output is consistent with what local QSs, contractors and clients expect to see.
Your country's takeoff format, not a generic template
The bill is generated in the measurement standard and layout your local quantity surveyors, contractors and lenders expect — element by element, item by item, carried to summary.
Downloads include a formatted PDF and a spreadsheet (XLSX/CSV) in the same layout — item references, unit, quantity, rate and amount columns exactly as bills are prepared in your market.
The questions that come up most often
What kinds of drawings can I upload?+
Dimensioned architectural drawings — floor plans, elevations, sections — as PDF, PNG or JPG, up to 25 MB per file. The more clearly your drawings are dimensioned, the more accurate the take-off will be.
How accurate is the takeoff?+
On standard residential and small commercial projects with well-dimensioned drawings we typically see 95–98% accuracy against a manual take-off. Complex schemes and poorly dimensioned drawings should be reviewed by a QS before tender.
Which countries and currencies are supported?+
190+ countries. Unit rates are looked up from regional market data in your chosen currency. Payment is taken in USD; the takeoff itself is priced in whatever local currency you select.
How long does an analysis take?+
Most projects complete in two to five minutes. Very large drawing sets can take a little longer; the engine works asynchronously so you can leave the tab open or come back to a saved takeoff.
Can I re-download a takeoff later?+
Yes. Every takeoff you generate is saved against your Google account and is available from the “My takeoffs” panel at the top of the page.
Do you replace a quantity surveyor?+
For early-stage feasibility, value-engineering and budget setting, yes — most clients use us instead of paying for a manual take-off. For tender-stage documents on complex projects, treat the takeoff as a strong first draft that a QS can verify in a fraction of the usual time.
Upload a drawing. See a priced takeoff in minutes.
Create a free account, upload your dimensioned drawings and pick a country and tier. Then pay for just that project, or go monthly if you price jobs often. No minimum, no contractor lock-in.
Pricing more than one job a month?
A monthly plan brings the cost of each quantity takeoff right down. Create a free account to compare the options side by side. You only pay when you pick one.
Now find someone to build it
Once you have the quantities, the directory has the yards, contractors and quantity surveyors who can price them. Send one request and every supplier quotes against the same measured line items, so the numbers coming back are actually comparable.

AI takeoff vs on-screen takeoff
Manual digital takeoff means tracing every wall and counting every door yourself, often in Windows-only desktop software. AI takeoff does the first measure for you and prices it, so your time goes into checking and winning work, not clicking. Compare tools in our takeoff software guide.
What is AI takeoff?
A quantity takeoff measured by software instead of by hand: the AI reads the drawings, identifies walls, openings, slabs, roofs and finishes, and calculates the quantities an estimator would otherwise click out on screen.
Is there free takeoff software?
Yes. You can upload plans and preview a takeoff here for free, and while the trial runs the first 7 complete takeoffs cost nothing.
How is a takeoff different from a bill of quantities?
The takeoff is the measurement. The bill of quantities is that measurement organised into trades and items, with rates applied. This tool does both in one pass, so you get quantities and a priced bill together.
Do I need to install anything?
No. It runs in the browser on desktop or phone. Upload drawings, and the results can be exported to Excel for your own pricing or tender.
How accurate is an AI takeoff?
Treat it as a fast first measure to check, not a signed-off final. It removes hours of clicking; an estimator should still review quantities against the drawings before a tender goes out.
