An AI Floor Plan Generator That Starts From What You Already Have
Most plans do not start from a blank canvas. They start from a napkin sketch, a builder PDF, or a photo taken on a walkthrough. Upload what you have and the AI rebuilds it as a clean, measured, editable floor plan you can furnish and render in 3D.
No subscription required for 2D plans and 2D exports — pay per export credit. Trusted across 415,000+ projects.
How does an AI floor plan generator work?
An AI floor plan generator takes an existing input — a hand sketch, a photo, or an older plan — detects the walls, doors, and room boundaries in it, and rebuilds them as editable vector geometry with real dimensions. In AI Floor Plan Builder, that generated plan is a fully editable drawing rather than a flat image: the AI can also auto-furnish each room with appropriate fixtures, calculate ANSI-compliant Gross Living Area automatically, and lift the result into interactive 3D in one click. You stay in control, because every wall the AI places can be moved, split, or deleted by hand.
Everything the app does
Rebuild from a rough sketch
Hand-drawn lines and uneven angles are interpreted into straight, snapped walls with consistent thickness and clean corners.
Generate from a photo
Photograph an existing plan on a wall or a printed sheet and the AI reconstructs it as a live, editable drawing.
AI auto-furnishing
Let the AI place beds, seating, counters, and fixtures that suit each room type, then swap any item you disagree with.
Automatic ANSI square footage
Gross Living Area is computed as the geometry is generated, following ANSI measurement standards without manual math.
One-click 3D from generated plans
Anything the AI produces converts straight into a furnished 3D model and a first-person walkthrough of the space.
Fully editable output
The result is real geometry, not a picture of a plan. Drag a wall and the dimensions and square footage recalculate instantly.
Room detection and labeling
Enclosed spaces are recognized as separate rooms so each one carries its own name and area figure on the finished plan.
Iterate in seconds
Try a different layout, regenerate the furnishing, and compare options far faster than redrawing a plan by hand.

How it works
- 01
Upload your input
Bring a sketch, a photo of a printed plan, or an existing drawing you want cleaned up and modernized.
- 02
Let the AI rebuild it
Walls, doors, and rooms are detected and reconstructed as editable geometry with live dimensions attached.
- 03
Refine and furnish
Nudge anything the AI got wrong, then auto-furnish rooms or place items yourself from the object library.
- 04
Generate 3D and deliver
Convert to interactive 3D, walk through it in first person, then export or share a live link.
Why teams pick this floor plan app
- Generated plans are editable geometry, not flat images you cannot change
- AI auto-furnishing fills rooms with fixtures that match how the space is used
- ANSI-compliant Gross Living Area calculated automatically on generated plans
- One-click conversion from AI-generated 2D into interactive 3D
- First-person walkthrough mode for showing clients the generated space
- Runs in the browser with nothing to install and no CAD experience needed
- No subscription required to draw 2D plans and take 2D exports
- Roughly $1 or less per export credit, so a single project stays cheap
Frequently asked questions
Can an AI floor plan generator work from a hand-drawn sketch?
Yes. That is the most common starting point. The AI interprets uneven hand-drawn lines as intended walls and rebuilds them snapped and squared, so a napkin sketch becomes a usable measured plan.
Is the AI-generated plan editable afterward?
Completely. The output is real vector geometry, so you can drag walls, change room boundaries, and add openings. Dimensions and square footage update live as you edit.
How accurate is the generated square footage?
Area is calculated from the geometry using ANSI measurement standards, so it is consistent and repeatable. Its real-world accuracy still depends on the dimensions of your input being correct — verify measurements for appraisal work.
Does it also generate the 3D model?
Yes. Once the 2D plan exists, one click lifts it into a furnished 3D model you can orbit or walk through in first person. You do not model the 3D separately.
What if the AI misreads part of my sketch?
You correct it directly in the editor. The AI is a starting point that removes the tedious tracing work, not a black box — every element it places is yours to adjust.
Do I need CAD or design experience to use it?
No. The generator is built for photographers, agents, and contractors rather than draftspeople. If you can upload an image and drag a line, you can produce a finished plan.
What does the AI generator cost?
Drawing and 2D exports need no subscription. Credits cover advanced exports and work out to roughly $1 or less each, so you pay per finished deliverable rather than monthly.
