HousePlanAI
HousePlanAI is a free, browser-based tool that transforms natural language descriptions of a home into editable 2D floor plans. Users specify plot size, lifestyle preferences, and layout requirements, and the AI copilot asks guiding questions before generating a full plan with rooms, doors, windows, and boundary walls. The platform supports common plot sizes in both feet and meters and allows complete customization of every element. Beyond generation, HousePlanAI provides professional 2D drafting tools with crisp wall poché, door swings, window symbols, live dimensions, and room areas. Any plan can be viewed as a 3D model with furniture, and a cinematic walkthrough from the street through every room is available. The tool also supports multiple floors, stairs (including straight, U-shaped, winder, and spiral), open terraces, and railings, calculating riser and tread automatically. Additional features include a construction cost estimator that provides trade-by-trade breakdowns in the user's currency, and sharing/export capabilities such as one-link sharing, PNG exports, and an A3 PDF plan sheet with title block, schedule, and areas. No account is required to start designing, making it accessible to homeowners, designers, and builders.
