Built by a building quantity surveyor

The right plan.
The take-offs on their own.

Draw the plan the way you work on site — dimensions to the wall face, a Bluetooth laser meter, sockets, ducts, AC. Kotelio counts everything for you: areas, doors and windows, fixtures room by room, ducts by the metre, and even a proposed electrical panel.

Your client file is ready in 2 hours, not 2 days.

What the others don't do

You draw. Kotelio counts.

Consumer floor-plan apps make pretty drawings without a single usable figure. Professional quantity-surveying suites do the numbers, but cost several thousand euros and weeks of training. Kotelio bridges the gap — built by a quantity surveyor, for people in the building trade.

m²

Automatic areas & openings

Every room knows its area, every door and window its tag (P1, F1…), its size, its sill height. Printable schedules and Excel-ready CSV — zero re-keying.

⌁

Fixtures counted room by room

Sockets, lights, water feeds, AC: dropped on the plan, counted per room with their mounting height. Ducts measure themselves, in linear metres by type.

≣

The proposed electrical panel

From your layout, Kotelio proposes the split into circuits and draws the panel schematic — to your country's standard: NF C 15-100, CEI 64-8, VDE 0100 or REBT. The first draft that only high-end electrical software could produce.

⇢

Bluetooth laser meter

Leica DISTO, Bosch GLM: every laser reading sets the wall to the exact dimension, straight into the plan. No more notebook to copy out at night, no more transcription error.

◰

Camera survey & scale calibration

Drop the room corners on the floor with the phone camera, or import the PDF of a plan with no dimensions and set the scale from a known area: the estimate starts right away.

⌂

3D, walkthrough & pro exports

A day/evening/night virtual walkthrough to sell the project, then the file: scaled PDF, AutoCAD DXF with trade layers, ceiling plan, Sweet Home 3D, Excel CSV. And the app speaks five languages — French, English, Spanish, German, Italian, manual included.

The method

From measuring up to the client file

Set your surveyImport the PDF or a photo of the plan and set the scale in 2 clicks — or measure straight from the Bluetooth laser meter.
Draw to the faceWalls snap, ends stop at the wall face, angles set to the degree — Kotelio can even propose the walls from the background plan.
Fit out the planDoors, windows, fixtures, ducts, furniture, pool — everything clings to the wall, everything gets counted.

Frequently asked

Everything people ask us

Where do my plans go?

Nowhere: Kotelio runs on your side — on your computer or your phone, your plans stay on the device. No mandatory account, no imposed cloud (the sync cloud is optional and encrypted on YOUR device).

Does it work with AutoCAD?

Yes: DXF export with clean trade layers (WALLS, DOORS, ELEC, PLUMB, AC, DUCTS…), in metres. And also scaled PDF, PNG, Sweet Home 3D and CSV for Excel.

Does the proposed electrical panel replace the electrician?

No — it's a preliminary proposal (8 sockets max per 16 A circuit, dedicated circuits, 30 mA RCDs) that saves you the hour of the first draft. Validation stays with the electrician, and it says so on the drawing.

Does it work on a phone?

Yes: Kotelio installs like an app (PWA), works offline on site, and the survey is done with the Bluetooth laser meter or the camera (Android, Chrome browser). The tool panel folds down to the bottom of the screen, made for your thumb.

Do I need training?

An hour and the illustrated manual are enough: the tools are arranged like a building site — structural work, fit-out, finishing.

How much does it cost?

€159 a year (about €13 a month), or €19.99/month with no commitment for a one-off need — all features and updates included. During the beta it's free by invitation, and the launch price is guaranteed to beta testers. For comparison: the pre-sales software on the market costs €900 to 1,400 a year — six times more.

Your next survey can already be done with Kotelio.

The beta is free, setup takes 2 minutes, and your feedback shapes the software.
