Free AI Floor Plan Generators: Which Ones Work?

Matterport’s free tier is the best free floor plan option for one reason: you get a floor plan and a 3D tour from the same scan. Walk through the property with your phone, capture each room, and Matterport’s AI generates both assets. You do not need any additional apps, subscriptions, or equipment.

The catch is the “1 active space” limit. You can only have one property live at a time on the free tier. To scan a new property, you must delete the previous one. For agents listing one property at a time, this works. For teams or agents juggling multiple listings, the $12/month starter plan removes this limit.

The floor plan quality is schematic — it shows room layout, approximate proportions, and room labels. It does not include precise dimensions. For most MLS listings, this is acceptable. Buyers want to understand the flow of the home, not measure for custom cabinetry.

magicplan’s free tier lets you scan rooms and generate floor plans using your phone’s camera or LiDAR sensor. The scanning quality is good — rooms are detected accurately, and dimensions are close to actual measurements when using LiDAR on a compatible iPhone or iPad.

The limitation is export quality. Free exports are low resolution with magicplan branding. You can view the floor plan in the app and share a link, but downloading a clean, high-resolution image or PDF requires upgrading. At $10 per floor plan (pay-per-use), upgrading for specific listings is affordable — you only pay when you need a professional export.

Floorplanner is a browser-based floor plan editor. You draw walls, place doors and windows, and add room labels using a drag-and-drop interface. It does not scan rooms — you input measurements manually from your own measurements or from a builder’s plan.

The free tier is notable for having no watermark on exports. You get one project with full 2D export capability. If you have measurements in hand (from an appraisal, builder plans, or your own tape measure), Floorplanner produces a clean floor plan at zero cost.

The trade-off is speed. Drawing a floor plan manually takes 15-30 minutes depending on property complexity. Scanning apps like CubiCasa or magicplan do the same work in 5 minutes. If you only need occasional floor plans and have measurements available, Floorplanner saves money. If you produce floor plans regularly, a scanning tool saves time.

Sweet Home 3D is free, open-source floor plan software that runs on your desktop. It offers the most features of any free option — unlimited projects, no watermarks, 3D rendering with furniture placement, and a library of thousands of 3D objects. The price is zero, permanently.

The catch is usability. Sweet Home 3D is a desktop application with an interface designed for precision, not speed. Drawing a floor plan takes longer than browser-based alternatives, and there is a learning curve to understand the tools. It has no mobile scanning — every measurement must be input manually.

For agents who produce floor plans regularly and want maximum control over the output without paying a monthly fee, Sweet Home 3D is worth learning. For agents who need a quick floor plan twice a month, scanning apps are faster.

RoomSketcher’s free plan lets you create basic 2D floor plans in your browser. You draw walls, add rooms, and place furniture. The interface is cleaner and more modern than Sweet Home 3D, making it easier to learn.

The free plan is restrictive. Exports are low resolution with RoomSketcher branding, and 3D rendering is locked behind the $49/month plan. For most agents, the free tier serves only as a trial to decide whether the paid version is worth the subscription.
