GLA math that runs as you draw.
Draw rooms on your phone or tablet — the tool computes ANSI Z765 finished-above-grade GLA in real time. Below-grade and non-finished areas split out automatically. No second app, no spreadsheet, no math errors.
How it works, step by step.
- 01Pick graph scale
Imperial or metric, grid snap on or off. The tool starts clean.
- 02Draw the exterior walls
Tap corners. L-shapes and bays are first-class, not a hack.
- 03Add interior partitions
Kitchen, living, bedrooms, baths — label each. Finished-above-grade flag per room.
- 04GLA panel updates live
Right-hand panel shows finished above grade, below grade, and non-living-area totals.
- 05Export to the URAR
Room count and GLA flow straight into the Improvements section. Sketch PDF attaches to the workfile.
Everything in this feature.
Finished-above-grade only for GLA, with proper below-grade and non-living separation.
Non-rectangular geometry supported, including angled walls and radius corners.
Each room is a typed room (kitchen/LR/DR/BR1…) with finished/non-finished and above/below grade flags.

The PWA stores sketches locally so you can draw in a no-signal basement. Syncs when you're back online.
Quick answers.
- Yes. The GLA math implements the ANSI Z765-2021 standard (finished above grade only), with below-grade split out for the Improvements section.
