AI Construction Estimating Software
RenoCalc uses purpose-built AI to read your floor plan — measuring every room, detecting every door and window — then generates a full renovation quote across 12 trades. Not a chatbot. Real AI, built for builders.
What is AI Construction Estimating Software?
AI construction estimating software uses machine learning to read floor plan images, measure room dimensions, and automatically calculate labour and material costs across all trades — producing a complete renovation quote in minutes rather than hours. RenoCalc is purpose-built for UK builders and achieves ~95% accuracy when a scale calibration is set.

See It Happen
Watch RenoCalc's AI read a floor plan, detect every room and dimension, and build a complete renovation quote — live, step by step. This is not a chatbot guessing. This is purpose-built construction AI.
How It Works
No manual measurement. No site visit needed. No spreadsheet setup. Upload and go.
Estate agent PDFs, Rightmove plans, architectural drawings, hand-drawn sketches — any image where rooms are visible and labelled will work. Take a photo on site and upload it there and then.
Mark one known measurement on the plan — a wall dimension, a room length, or the scale bar. RenoCalc uses this to convert every pixel measurement into real millimetres. This is what lifts accuracy to ~95%.
The AI reads every room label, traces wall boundaries, detects doors and windows, calculates floor areas, and loads all 12 trades with the correct dimensions. Automatically. Nothing manual.
A 30+ sheet Excel workbook, cover letter, schedule of works, method statements for every trade, and a materials shopping list — all ready to send to your client. In under 3 minutes from upload.
Detection Capabilities
Every data point the AI extracts feeds directly into the cost calculation. Nothing is guessed. Nothing is averaged from generic data.
The AI reads every room label — Kitchen, Living Room, Master Bedroom, Bathroom — and maps each one to the correct trade scope, material types, and calculation logic.
Feeds all 12 tradesLength, width, and floor area per room — measured in millimetres once calibration is set. Dimensions drive plasterboard, flooring, skirting, tiling, and painting calculations for every room.
Millimetre precisionAll openings are detected and their areas are subtracted from wall measurements automatically — reducing material overestimation on plastering, tiling, and decoration without any manual input.
Reduces material wasteStud partition walls are identified separately and feed into structural and decoration calculations — giving you accurate stud timber, plasterboard, jointing compound, and labour estimates automatically.
Stud & plasterboardThe AI sums all room areas to produce a total property floor area — used for flooring, underlay, heating load calculations, radiator sizing, and high-level project scope assessment.
Drives BTU calcsReads the scale bar or annotated dimensions on the plan to convert pixel distances into real millimetres. One 10-second calibration step is what takes accuracy from a rough estimate to ~95%.
Key accuracy stepNot All AI Is Equal
HBXL tested ChatGPT for construction estimating and found it useless. They were right — about ChatGPT. They were wrong about AI estimating as a whole.
Reads floor plan images directly — geometric analysis of the actual drawing you upload
Measures actual room dimensions in millimetres from the calibrated plan
Applies real UK construction rates per trade — not generic averages
Outputs a professional Excel file — 30+ sheets you can edit and send today
~95% accuracy with calibration — benchmarked against real renovation quotes
Safe to use for real quoting — verified output, not speculative text
Cannot read floor plans — no spatial or geometric analysis capability
Cannot measure dimensions — has no access to scale, pixels, or real dimensions
Estimates are entirely guessed — plausible-sounding figures with no real basis
Output is chat text only — not a structured quote you can use professionally
No verified accuracy — impossible to benchmark against real construction costs
Do not use for real quotes — could seriously misrepresent costs to a client
Dismissing all AI estimating because generic chatbots can't do it is like dismissing GPS navigation because a calculator can't give you directions. HBXL tested the wrong thing. RenoCalc is a different category entirely.
Accuracy
RenoCalc's accuracy varies by plan type and whether calibration is set. These figures are benchmarked against completed renovation quotes on real UK projects.
~95% accuracy means a job quoted at £50,000 by the AI would come in within £2,500 of the manual equivalent. For a first-pass quote — one that helps you decide whether to pursue a job at all — this is more than sufficient. You can fine-tune the Excel output afterwards.
Test it on your own floor plan →Calibration takes ~10 seconds. It is the single biggest factor in improving accuracy — always worth doing.
Supported Plans
Almost any floor plan image works. These are the most common types used by UK builders and property developers.
Rightmove and Zoopla floor plans work perfectly. Download the PDF and upload it directly. The most common source for developer deals.
Professional CAD-drawn plans at any scale. Scale bars make calibration quick and accuracy tops out at ~93%. Ideal for pre-build estimates.
Works well if rooms are labelled and the sketch is reasonably to scale. Take a clear photo on a flat surface. Add a known dimension for best accuracy.
Screenshots from Rightmove, Zoopla, or any property portal work fine. Use the highest resolution available for best AI analysis quality.
Council portal plans include precise scale references — ideal for calibration. Extensions and loft conversions work particularly well with this format.
