AI-Powered Analysis

What the AI Detects From Your Floor Plan

RenoCalc uses purpose-built AI construction estimating software — not a generic chatbot — trained to understand construction drawings. One calibration measurement and it calculates everything else proportionally.

Rooms & Dimensions

Identifies every room by name and type — bedrooms, bathrooms, kitchen, hallways, utility rooms. Calculates length, width, floor area, wall area, and ceiling area for each.

Doors & Openings

Detects every door on the plan, classifying internal and external doors. Each door is logged with dimensions and room location for accurate joinery costing.

Windows & Glazing

Finds windows of all sizes, estimating dimensions from the plan. Window areas are deducted from wall surface calculations so paint and plaster quantities are precise — not inflated.

Internal Partition Walls

Identifies stud partition walls and calculates their length, height, and both-side surface area. Generates accurate plasterboard, timber, and insulation quantities automatically.

Calibrated Measurements

You provide one known room width, and the AI scales every other measurement proportionally. Achieves accuracy within 5% of manual takeoff when calibrated correctly.

Radiator & BTU Calculations

Calculates heat loss per room based on floor area, external walls, and window area. Recommends correctly sized radiators with BTU ratings for each room in the property.

Your Quote Includes

A Complete Renovation Quote — Not Just a Number

RenoCalc doesn't give you a vague estimate. You get a fully detailed, editable Excel workbook with everything a builder needs to price and deliver the job. Unlike manual spreadsheets, generic estimating tools like Buildxact, or guesswork from online calculators — every figure is generated directly from your actual floor plan.

  • Room-by-Room Cost Breakdown

    Every room itemised by trade: electrics, plumbing, plastering, decorating, flooring, carpentry, tiling, and more.

  • Materials Shopping List

    Exact quantities: plasterboard sheets, cable metres, paint tins, copper pipe, skirting lengths, screws, fixings — hand it straight to your supplier.

  • Labour Hours & Costs

    Trade-specific labour rates and estimated hours per task. Adjust rates to match your area and the spreadsheet recalculates instantly.

  • Radiator Schedule

    BTU calculations per room with recommended radiator sizes. Based on floor area, external walls, and glazing.

  • Editable Excel with Live Formulas

    Not a locked PDF. Swap materials, change quantities, add your margin — formulas update the total automatically. It's your quote to customise. Perfect for builders who need professional quoting software without the learning curve.

  • 30+ Detailed Worksheets

    Separate sheets for each trade, summary sheets, schedule of works, stud partitions, MF ceilings, and project overview.
