Strukt AI turns a 2D floor plan image into a furnished 3D home in your browser. It reads the walls, doors, windows and room names from your drawing, designs and furnishes every room, and lets you walk through it with baked, realistic lighting, render photoreal images and export the model. It is built for interior designers, builders and homeowners.

Which files can I upload?

PNG, JPG or WEBP images of your floor plan, up to 15 MB on the homepage upload. Scans and phone photos work. If your plan is a PDF or a CAD (DWG/DXF) file, export or screenshot it as an image first — direct PDF and CAD upload is not supported yet.

How long does it take?

About 5 minutes from uploading your plan to an editable 3D model, for a typical floor plan. Larger or less clear plans can take longer. Rendering, furnishing and material changes happen after that, at your own pace.

How accurate is the 3D model?

Accuracy depends on how clear your drawing is. Clean, high-resolution plans give the best results. Some walls, openings or room boundaries can be read wrongly, and dimensions are estimates, so check the model and correct anything the AI got wrong. Strukt AI is for visualisation and design, not for construction drawings or permit submissions.

You can start free: every account gets 10 floor plans a month with the Free model, plus the 2D editor, 3D view, texturing and export, with no credit card. For the Pro model (rooms and names, automatic furnishing), baked walkthroughs and AI renders you buy credits: 2,000 credits cost ₹200, with no subscription, and they never expire while your account is active.

Can I edit the model after it is generated?

Yes. It is a real 3D model, not a picture. You can adjust walls, doors and windows, move, turn, resize or delete furniture (the AI re-plans the rest of the room around your changes), change floors, paint and other finishes, and re-render whenever you like.

Does it work for houses with more than one floor?

Yes. Add up to three upper floors to a house; Strukt lines them up and stacks them in 3D. Furnishing and baking the whole house, and walking up the stairs between floors, are rolling out now.

Can I export to other software?

Yes. Export to GLB and DAE (Blender, Unity, Unreal, Three.js), native BLEND, and IFC for Revit, ArchiCAD and other BIM tools, so you can continue in your own workflow.

Can I use the renders to market a property?

Yes, as visualisations. Renders are AI-generated and are labelled as such. Do not present them as photographs of a finished property, and remember that furniture, materials and lighting are approximate.

Who owns my designs, and is my data private?

You keep ownership of your original designs. Private projects are not shown publicly unless you publish them to the community. We do not sell your data, and you can ask us to delete your account and files at any time. See our Privacy Policy for details.

Floor Plan to 3D Online, Free — No Download (2026)

Convert a floor plan to 3D, free, in your browser

Upload an image of your plan (PNG, JPG or WEBP) and get an editable, furnished 3D model in about 5 minutes. No download, no card.

Convert your plan

You have a floor plan — a PDF from an architect, a screenshot from a listing, a photo of something printed on paper — and you want to see it as a real, walkable 3D space. Not a mockup. Not a stock render. The actual rooms, at the actual size, that you can furnish and walk through.

That's what Strukt AI does, entirely in your browser, with the free tier needing no card and no install.

What you get, specifically

—An editable 3D model built from your plan's actual wall geometry — not an AI-generated picture of a room.
—Walls, doors and windows placed where your plan actually has them, at the scale you set.
—A first-person walkthrough you move through with the arrow keys or WASD.
—Export to GLB, BLEND, DAE or IFC when you want to take the model further.

How it works

Upload the image

PNG, JPG or WEBP, up to 15 MB. A clean PDF export or a clear phone photo of a printed or hand-drawn plan both work.

Pick Free or Pro

The free model reads walls, doors and windows — enough for most plans. The Pro model additionally reads room-name labels and recognises balcony railings and sliding doors, and unlocks automatic furnishing.

Check what it read

In about five minutes you see your plan with its geometry drawn on top. Fix anything that looks off in the 2D editor, and set the scale from one wall whose real length you know.

Walk it in 3D

Switch to 3D View to orbit the model, or FPV to walk inside it at eye level.

Nothing is installed and nothing leaves the browser tab except the image you upload. There is no 3D software to learn — if you can drag a file into a web page, you can do this.

Why "online and free" usually means "a picture," not a model

Most tools that promise a free floor-plan-to-3D conversion actually generate a single image — an AI's impression of what a furnished version of your room might look like. It can look convincing, but there's no real geometry behind it: you can't move a wall, swap a piece of furniture, or walk through it. Strukt reconstructs the plan as real 3D geometry first, which is what makes editing, walking through and exporting possible afterward.

Who uses this

—Homeowners who want to see their own flat furnished before buying anything.
—Buyers checking whether a listing's floor plan actually fits their furniture.
—Students and hobbyists who want a 3D model without learning CAD or Blender from scratch.

Frequently asked questions

Is it actually free?

Yes. The free model needs no card and no subscription, with 10 plans a month. Credits are only used for extras like Pro detection, furnishing with Pro, baking and renders.

What file types can I upload?

PNG, JPG or WEBP images, up to 15 MB. Save a PDF or CAD drawing as an image first, or photograph a printed or hand-drawn plan.

Do I need to know 3D software?

No. Uploading, checking the result and walking through it all happen in the browser with no 3D modelling skills needed.
