Walkthrough · homes and shops

Walk through it before it's built.

Upload a floor plan. AI reads the walls, doors, windows and rooms, every room gets furnished and decorated in the style you pick, and you walk through it in 3D. Record a tour, make a photoreal render and send your client a link.

01 · How it works

Floor plan in. Furnished walkthrough out.

Four steps, usually a few minutes from drawing to tour.

01

Upload or draw the plan

Drop in a PNG, JPG or PDF of the floor plan, open one of the four samples, or draw rooms as rectangles: shared walls join up and the rooms are found for you.

02

AI reads the drawing

The walls, doors, windows, room names and scale come back as an editable plan laid over your drawing. Drag anything that is off and set the scale from any dimension you know.

03

Furnish and decorate

One click furnishes every room for its use and size. Pick a style, then change any room's paint, feature wall, floor and ceiling, or describe the look and let the AI decorate.

04

Walk, tour and share

Walk through at eye height with doors that open as you reach them. Record an automatic room-to-room tour as a video, make a photoreal render, or share a view-only link.

02 · Features

Everything between the plan and the tour.

01

AI plan reading

Walls, doors, sliders, windows, openings, room names, built-in fixtures and the scale, read from an image or a PDF page.

02

Plan editor

Rectangle rooms, walls with snapping, doors and windows on walls, lengths on every wall, measuring, scale calibration and unlimited undo.

03

71 pieces

Living, dining, kitchen, bedroom, bathroom, laundry, office, decor, retail, cafe and outdoor pieces. Resize, turn and recolour any of them.

04

Automatic furnishing

Beds against the right wall, sofas facing the TV, kitchen runs, bathroom fixtures, shop shelving in aisles, with door swings kept clear.

05

Decorating

Twelve styles, 28 paint colours, feature walls, 19 floor finishes from photo-scanned oak to terrazzo, ceiling colours and outside walls.

06

Tours and video

Set your own viewpoints or let the automatic tour visit every room through its doors, then record it to a video file in the browser.

07

Photoreal renders

Turn the view you are looking at into a photograph-style image in daylight, golden hour, soft light or evening.

08

Share and export

View-only links for clients, PNG screenshots, a room schedule as CSV and a project file you can open again anywhere.

03 · The AI

Which AI does what.

The 3D model, the walkthrough and the furniture layout are worked out in your browser, so they are instant and free to use. AI is used in three places, only when you ask, and comes with a Pro account.

Claude by Anthropic

Reading floor plans

A vision model traces the walls, doors, windows and fixtures in pixel coordinates, reads the room names and works out the scale from the dimension strings. The app then squares up the walls, joins the corners and finds the rooms from the wall layout.

Claude by Anthropic

Decorating

Describe the look and who uses each room. Claude chooses the style, paint, feature walls, floors and the furniture list for every room; the layout engine then places each piece so nothing blocks a door.

OpenAI image model

Photoreal renders

A capture of your view is repainted as a photograph while keeping the layout, furniture and camera angle. Treat it as a mood image: finishes and small details are the model's interpretation.

04 · Who it is for

For homes

  • Buyers checking an off-the-plan home or a renovation before they commit.
  • Builders and building designers showing a client the plan furnished.
  • Agents sending a walkthrough link with a listing.
  • Renovators trying paint, floors and furniture room by room.

For shops

  • Retailers and shop fitters planning a fit-out and the customer path.
  • Cafes testing seating layouts against the counter and kitchen.
  • Clinics, pharmacies and salons with a clean, bright fit-out.
  • Landlords showing a tenancy fitted out instead of empty.
05 · FAQ

Questions people ask first.

Can it read any floor plan?
It reads clean architectural plans, builders' plans and sales brochure plans best: walls drawn as solid lines, door swings, windows, room names and at least one dimension. Hand sketches and photos of plans work less reliably. You always get an editable plan to check against the drawing, and you can trace the plan yourself with the Room and Wall tools instead.
Which files can I upload?
PNG, JPG and WebP images and PDF files up to 25 MB. For a PDF with several pages you choose the page with the floor plan. HEIC photos from an iPhone need exporting as JPG first.
How accurate is the AI reading?
On a clear plan with dimensions it usually finds every wall, door, window and room and gets the scale from the dimensions. It is a drawing aid, not a survey: check the result against the drawing underneath, drag any wall that is off, and use Set scale if the size is wrong.
Do I need an account?
No account is needed to draw a plan, open the samples, furnish, decorate, walk through, record tours or export. Share links need a Build Design Solutions account, the same one as the designer, and the AI features (reading plans, decorating with AI and photoreal renders) need a Pro account. Access is by request: sign in or request access, then ask for Pro from the walkthrough.
Does it work for shops, cafes and offices?
Yes. Choose Shop or commercial and you get four fit-out styles (boutique retail, cafe, clean and clinical, warehouse store) and shop pieces such as counters, island shelving, wall shelving, clothes racks, fitting rooms, display fridges, cafe tables, banquettes and reception desks. Furnishing a shop floor lays shelving out in aisles.
Is my floor plan stored?
Your projects are saved in your own browser, not on our server. A drawing you ask the AI to read is sent to Anthropic's Claude for that one request and not kept. A share link stores a copy of the plan without the drawing for 90 days. See the privacy policy.
Can I show it to a client?
Yes. Share creates a link that opens a view-only walkthrough for anyone, without an account, for 90 days. You can also record the guided tour as a video file, save screenshots and photoreal renders, and export the room schedule.
Does it handle more than one storey?
One level per project for now. For a two-storey home, upload or draw each floor as its own project.
