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 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.

Convert Floor Plan to 3D Free — Online AI Converter (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. Maybe it's a PDF from your architect, a CAD file from a builder, or a photograph of a hand-drawn sketch. And you want to see it in 3D — furnished, textured, photorealistic — so you can actually make decisions about the space.

Until recently, getting there meant hiring a 3D modeler, waiting days, and paying hundreds of dollars. Or learning SketchUp yourself and losing a weekend. AI changed that — but most AI tools created a new problem: they give you a pretty picture that you can't edit.

This guide covers exactly how to convert a 2D floor plan to an editable 3D space using AI, what to look for in a tool, and why editability is the thing most people overlook until it's too late.

Why most AI floor plan tools fall short

The most common AI approach to "floor plan to 3D" is image generation — you describe a room or upload a plan, and the AI produces a photorealistic image. Tools like Midjourney, DALL-E, and dozens of interior design AI apps work this way.

The images look stunning. The problem: they're just images. There's no geometry behind them. You can't move the sofa. You can't change the flooring. You can't swap the kitchen cabinets to match what you saw at the showroom. If the client changes their mind — and they always do — you start over from scratch.

Real spatial design requires two things that image generators can't provide:

—Editable 3D geometry — actual walls, doors, furniture objects you can manipulate
—Real materials — not hallucinated textures, but actual products from real brand catalogs

Without both, the 3D output is a dead end the moment the client asks for a revision.

What the AI floor plan to 3D conversion process actually looks like

A proper AI-native pipeline for converting floor plans to 3D works in four stages. Here's what each step does and why it matters:

Upload your 2D floor plan

Drop in a PNG, JPG or WEBP image of any floor plan (save PDFs and CAD drawings as images first). A well-built spatial AI will repair broken lines, interpret wall thicknesses, detect room boundaries, and digitise dimensions automatically. You don't need a perfect, clean drawing — real-world floor plans are messy and a good system handles that.

AI generates the 3D structure

The spatial engine extrudes the 2D geometry into accurate 3D volumes. Walls become walls. Openings become doors and windows. Room boundaries become navigable spaces with correct floor-to-ceiling proportions. This is the step that separates spatial AI from image generation — there is actual geometry here, not a picture of geometry.

Furniture is detected and made editable

Any furniture indicated in the floor plan gets decomposed into individual components — not baked into the scene as a static mesh. This means you can hot-swap a sofa, swap cabinet finishes, or match pieces against a real brand catalog. This is what makes the output actually useful for client presentations.

Apply real materials and render

Apply laminates, tiles, paint colours, and lighting presets. Every material uses PBR (Physically Based Rendering) maps, so what you see in the 3D view is what a real photographer would capture in the finished room. Render it to a shareable image.

The key test: after you generate the 3D model, can you change the flooring to a specific timber from a specific brand without regenerating the entire room? If yes, you have a real spatial AI tool. If no, you have an image generator with a floor plan input.

Strukt AI vs legacy 3D software vs standard Gen-AI

Here's how the three approaches compare across the things that actually matter in a professional design workflow:

	3D software	AI image tools	Strukt AI
Starts from your floor plan	Redrawn by hand	No	Read automatically
Editable geometry	Yes	No (flat image)	Yes
Designs and furnishes rooms	You place every piece	Restyles one photo	Every room, keeps your edits
Materials	Manual setup	Invented by the AI	PBR materials you choose
Export to other tools	Yes	No	GLB, BLEND, IFC
Cost to start	High	Low	Free

Step-by-step: converting a floor plan to 3D with Strukt AI

Strukt AI is built specifically for this workflow. Here's how to do it:

—Go to app.struktai.work — no download, runs in the browser
—Create a free account or sign in with Google
—Click New Project and upload an image of your floor plan (PNG, JPG or WEBP)
—The spatial engine processes the plan — walls, rooms, and openings are detected automatically
—Your 3D model appears in the editor — navigate it, rotate it, zoom in
—Open the Warehouse to browse real-brand furniture and materials
—Apply textures, adjust lighting, and render a shareable image
—Use the AI chat to type changes in plain English: "make the kitchen island white marble"

How long the full process takes depends on the size and clarity of the plan, and complex commercial layouts take longer — but there is no manual modelling, and the output is a fully editable model, not a static image.

What file formats are supported?

Strukt AI accepts floor plans as PNG, JPG or WEBP images:

—PDF — the most common format from architects and builders. Export the plan page as a PNG or JPG first; direct PDF upload isn't supported yet.
—DWG / DXF — export the plan from AutoCAD or your CAD tool as a high-resolution image. Clean exports give the most accurate wall detection.
—PNG / JPG — scans, screenshots, or photographs of a floor plan. Good quality for standard residential plans; the AI repairs minor imperfections automatically.
—Hand-drawn sketches — photograph the sketch and upload the image. Works well when lines are clear and consistent.

Whatever format you have is the right format. You do not need to convert to a specific file type before uploading.

Who this is most useful for

Interior designers

The biggest workflow unlock is eliminating the rebuilding step. Instead of spending hours manually constructing a 3D model from a client's PDF, you start the design conversation immediately. The AI handles the geometry; you handle the taste. See the designer-specific features for more on the client presentation workflow.

Architects

Quickly validate spatial proportions and produce client-ready visualisations without switching tools. Useful for early-stage design reviews where you need to show options fast without committing to full renders. How architects are using AI for early-stage visualization →

Homeowners

If you're renovating, you probably have a floor plan from your builder but no way to visualise the finished space. Strukt AI lets you upload that plan, apply the materials you're considering (the actual tiles from the actual brand), and see the result before you commit to anything.

Common questions

Does the floor plan need to be a clean CAD file?

No. The spatial engine handles scans, photographs of printed plans, and even clear hand-drawn sketches, uploaded as images. It repairs broken lines and normalises dimensions. Clean images exported from CAD give the most accurate results, but a clear photo works well for most residential plans.

Can I edit the 3D model after it's generated?

Yes — that's the core point. Every element stays live. You can move walls, swap furniture, change materials, adjust room layouts, and re-render as many times as you need. Nothing is baked.

Is it free?

Strukt AI has a free tier at app.struktai.work. No credit card required to try the core 2D-to-3D conversion.

The bottom line

Converting a 2D floor plan to 3D with AI is no longer a technical challenge — it's a tool selection problem. The wrong tool gives you a beautiful image and a dead end. The right tool gives you a live, editable 3D model that you can use throughout the entire design process.

The checklist is simple: can you edit the geometry? Can you apply real brand materials? Can you change things in plain English without regenerating from scratch? If all three answers are yes, you have a tool worth using.
