★ #1 AI floor plan generator & 3D design studio

The AI floor plan generator that builds in 3D — design, furnish & render in your browser

Luw.ai Studio is a browser-native floor plan app and 3D design studio. Describe a brief — or drop a photo — and Archiagent, the in-editor AI architect, draws the floor plan, models it in 3D, furnishes every room to scale, audits its own work, and renders any view in up to 8K. No CAD, no install, no GPU.

From the first wall to the final render

One studio. Floor plan, 3D, furnishing, render.

Most AI tools generate a picture. Luw.ai Studio generates a real, editable, measurable building — a 3D floor plan you can walk through, furnish, export to CAD, and render. The AI floor plan generator and the render pipeline live on the same canvas.

01 — AI floor plan generator

From a sentence to a scaled floor plan

Type "design a 1-bed, 80 m² apartment, kitchen on the south wall" and the AI floor plan generator draws walls, doors, windows and zones to scale — on the metric system, with live dimensions and red door-swing arcs you can audit in 2D. It's a floor plan creator, floor plan maker and floor plan app in one, with architectural defaults that make the output buildable.

✓ Natural-language brief → scaled 2D & 3D floor plan
✓ Walls, 9 door types, 10 window types, columns, stairs, roofs
✓ Neufert-baseline room sizes & clearances built in

02 — 3D floor plan & room planner

A real 3D floor plan — and a room planner you can walk through

Model up from a 2D floor plan to a fully detailed 3D building: multi-storey levels, curved walls, parametric columns, 7 roof types and stairs that cut their own floor opening. Switch to first-person walk mode at 1.6 m eye height, open doors with a keypress, and render exactly where you're standing. It's the most capable browser-based 3D floor plan and room planner available.

✓ 2D blueprint, 3D perspective & side-by-side split view
✓ Multi-storey levels with drag-to-reorder & exploded view
✓ WebGPU-accelerated walk-through with real collision

03 — Photo to floor plan

Photo to floor plan — drop an image, get an editable 3D model

Have an old drawing or a phone photo of a floor plan? Drop it into the chat and Archiagent reads the walls, rooms and approximate dimensions, then rebuilds the whole layout as a real, editable 3D scene. Photo to floor plan is the feature your competitors don't have — turn any picture into a measurable model in seconds.

✓ Floor-plan image → walls, rooms, openings (with confidence)
✓ Room photo → dimensions, fixtures & windows
✓ iOS RoomPlan scan → positioned 3D mesh you build on

04 — AI interior design & auto-furnishing

Home design AI that furnishes every room

Ask for "Scandinavian living room" and the home design AI places furniture from a 150+ item catalog with code-level rules: beds against headboard walls, sinks on the plumbing wall, sofas clear of door swings. It's interior design AI and AI room design in one — and the same canvas does the rest of the building, so your AI home design stays consistent end to end.

✓ 150+ catalog items + your own AI-generated 3D objects
✓ AI pattern library for wallpaper, parquet, marble & finishes
✓ Every placement validated against door swings & clearances

Try AI interior design

05 — Self-audit

It checks its own work, in 2D, every time

This is the part nobody else has. After every furnishing pass, Archiagent runs a mandatory 2D blueprint check — bright-red door-swing arcs make forbidden zones impossible to miss. Overlapping items, beds without a headboard wall, a sink off the plumbing wall, a sofa blocking circulation — it catches and fixes them before it ever says "done." Most AI guesses; Archiagent verifies.

✓ Hard validator rejects any placement inside a door swing arc
✓ Mandatory 2D self-check after every batch
✓ Never guesses coordinates — candidates are generated & ranked

06 — Render & walk

Walk through it. Render it in 8K. Same canvas.

Frame any view — or press Enter in walk mode — and the AI render pipeline turns your 3D floor plan into a photo-real, painterly or stylized image, up to 4K and 8K, with your prompt, reference image and day/night control. Renders save to your Luw.ai dashboard with a shareable link.

✓ 4K & 8K output, photo-real or stylized
✓ Prompt + reference image + day / night
✓ One keypress from walk mode to render

Meet Archiagent

The first AI architect that audits its own work

Archiagent is the in-editor AI co-designer at the heart of Luw.ai Studio. It isn't an image generator — it has deterministic control over a real scene graph through 40+ browser-side tools, so every wall it draws and every item it places is editable, measurable and undoable. It works the way a real architect does: program → walls → openings → fixtures → furniture → 2D audit.

40+ deterministic tools

Create rooms, cut openings, place items, set materials, measure, capture 2D — every editor action is a typed, validated tool call, atomic and undoable.

Pick the best model

Gemini 3.1 Pro is recommended for floor plans and building; Claude (Haiku/Sonnet/Opus), GPT-5.5 and Kimi are available for complex reasoning. You're never locked to one model.

Validation, not vibes

A hard validator and a mandatory 2D self-check enforce real architectural rules — clearances, door swings, plumbing walls — so what you get is buildable, not just pretty.

Multimodal in

Drop a floor-plan photo, a PDF, a GLB or a sketch into chat — Archiagent reads it and turns it into a real layout via photo to floor plan.

Design variants on demand

"Give me 5 plans for this apartment" yields deterministic, comparable variants — different wall layouts, door positions and proportions — so clients pick the one they love.

Programmable via MCP

The same scene engine is exposed over the Model Context Protocol, so you can drive Luw.ai Studio headlessly from Claude Desktop, Cursor or your own agent.

Open Archiagent in Studio

Open, not walled-in

Import from CAD & BIM. Export everywhere.

Bring drawings in from Revit, ArchiCAD or AutoCAD, hand a measured plan to the contractor, send the model to Blender or Unreal, and give the client an 8K render — Luw.ai Studio plugs into your existing workflow instead of replacing it.

Import

↓ DXF — CAD drawings become live, editable wall nodes
↓ IFC — BIM from Revit / ArchiCAD / Tekla (early alpha)
↓ Floor-plan images — PNG / JPG / sketch via AI wall tracing
↓ GLB & LiDAR scans — drop a 3D capture and build on top

Export

↗ PNG & SVG floor plans — print-ready, fully dimensioned
↗ GLB / OBJ / STL — Blender, SketchUp, Unreal, 3D print
↗ .luw project file — portable & shareable
↗ 4K / 8K AI render — auto-saved to your dashboard

Why Luw.ai Studio is different

Luw.ai Studio differs from image generators and traditional CAD: it produces a real, editable 3D floor plan you design by chatting — then renders it, all in the browser, with an AI that audits its own work.

The agent for architecture

★★★★★

"It drew a 3-bedroom plan to code in under a minute. The door swings, the dimensions, the audit. Everything an intern would miss, it caught. This is the first time AI has actually helped me design."

Sarah Gabriel

Interior Designer

★★★★★

"I used to spend two days on a concept. Archiagent gives me ten variations in twenty minutes. Floor plan, furnishing, render. My clients pick the one they love. The agent does the rest."

John Douglas

Architect

★★★★★

"The self-audit is the part nobody else has. It checks its own plan in 2D after every step. Nothing collides with a door swing, every clearance is honored. It thinks like a real architect."

Floor plan AI — frequently asked

What is Luw.ai Studio?

Luw.ai Studio is a browser-based AI floor plan generator and 3D design studio. You describe a space in plain language — or drop a photo — and the built-in AI architect, Archiagent, draws the floor plan, models it in 3D, furnishes it, audits its own work, and renders it in up to 8K. No CAD skills, no install.

Is it a real floor plan app or just AI images?

It's a real floor plan app. Unlike AI image tools, every wall, door and item is genuine, editable, measurable geometry on the metric system. You get a true 3D floor plan you can walk through and export to GLB, OBJ, STL or a dimensioned SVG/PNG.

Can it turn a photo into a floor plan?

Yes. Photo to floor plan is one of Studio's signature features: drop a floor-plan image, a sketch or a room photo into the chat and Archiagent reconstructs the walls, rooms and approximate dimensions as an editable 3D scene. You can also scan a real space with the iOS app.

How is the AI floor plan generator different from a template floor plan creator?

A typical floor plan creator or floor plan maker gives you a blank grid to draw on. Luw.ai's AI floor plan generator drafts the whole layout from a sentence — rooms sized to Neufert baselines, doors placed with clearance, plumbing grouped — then lets you refine it by chatting or by hand.

Does it do interior design and home design AI too?

Yes — it's a home design AI and AI interior design tool as well as a floor plan app. Ask for an AI room design in any style and it furnishes the space from a 150+ item catalog (or your own AI-generated 3D objects), applying materials and validating every placement.

Can I import from Revit or AutoCAD, and export to Blender?

Yes. Import DXF (CAD) and IFC (BIM from Revit / ArchiCAD / Tekla — early alpha) and floor-plan images or GLB scans. Export GLB, OBJ and STL for Blender, SketchUp, Unreal or 3D printing, plus dimensioned PNG/SVG plans and 4K/8K renders.

Is it free? Is it a good house design app for beginners?

There's a free tier to start, with credits for AI renders and agent runs. Because you design by chatting, it's the most beginner-friendly house design app around — no CAD to learn — while still being powerful enough for professional architects.

Which AI model powers it?

You choose. Gemini 3.1 Pro is recommended for floor plans and building; Claude Haiku 4.5, Sonnet 4.6 and Opus 4.7, plus GPT-5.5 and Kimi 2.6, are available for more complex reasoning. The studio is also programmable over the Model Context Protocol (MCP).

Build something real.

Open Luw.ai Studio. Type a brief, or drop a photo. Watch the AI floor plan generator draw, furnish, audit and render — a real 3D floor plan, in your browser.
