Cavity Wall Insulation — Diagram Plan

Two ways to build a plan — use either, or mix them:
① Manual — type each wall’s Height & Width (metres), drag the Window/Door chips onto the grid (they snap to the grid; drag to move, resize from the corner), and enter each opening’s size in the tables.
② Auto-draft (AI) — click ✨ Auto-draft from plans, upload your floor plans, and Claude fills in a draft elevation for you — then tweak it by hand exactly like a manual one.
Totals and POPT update live; click Download PDF when finished. Work auto-saves in this browser.
