How It Works

HomeX guides you through the early stages of your home extension, helping you understand what’s possible before you commit. From planning checks and home scanning to designs, costs and trusted professionals, everything is organised into one simple, step-by-step journey.

Step by Step Flow

Smart Scan

SmartScan lets you measure and visualise your extension using just your phone. Quickly capture internal layouts and external footprints to create early-stage floor plans, understand your available space, and support feasibility, design, and cost planning all without specialist equipment or drawings.
