How to convert a 2D plan to 3D for free
- Draw your floor plan
Open the free plan maker, set your plot size and arrange rooms, doors and windows — or start from a template. - Save the plan
Press Save plan to download the .json file of your drawing (on a saved project, use Download). - Upload and walk through it
Drop the file above. Your 3D house opens in seconds — orbit around it, or walk inside.
What you can do in 3D — all free
Walk in at eye level
Move through every room at your own height with the keyboard, or with a joystick on your phone. Climb the stair to the terrace.
Six false-ceiling designs
Cove tray, two-step tray, wooden rafters, floating panel, profile lines or flat with spotlights — per room, with a lighting schedule.
Day, night and lighting scenes
Switch on cove LEDs, downlights and pendants, pick warm or cool white, dim them, and see the house at night.
Paint colours
28 shades in seven families and six ready schemes for the exterior, every room and the compound wall, with a paint schedule to copy.
Measure anything
Tap two points to measure a gap between furniture or the height of a window. Room sizes and ceiling heights are marked on the floor.
Save and share, free
Save each 3D house to your free account and share its link with family, your architect or contractor — by email or with anyone who has the link.
Real sizes, not a toy model
A model seen from above always looks smaller than the real house. The 3D view is built in feet from your exact plan, so you can judge the space properly:
- 9" walls, plinth 1'-0", floor to slab 12'-0"
- Doors 7'-0" high, windows with a 3'-0" sill
- Standard furniture: queen bed 5'-0" × 6'-6", 3-seat sofa, 4-seat dining
- People at 5'-8", 5'-2" and 4'-0" for scale
Frequently asked questions
Is the 3D house plan generator really free?
Yes, 100% free. Uploading a plan, viewing it in 3D, walking inside, trying ceilings, lights and paint colours, saving the 3D model and sharing it are all free. There is no paid plan and no card — you only need a free account.
Can I convert my 2D floor plan to 3D for free?
Yes. Draw your plan in the free floor plan maker, then press 3D view (or upload the saved .json file here). The 3D house is built in seconds from your exact walls, doors and windows, free.
Can I save my 3D house for free?
Yes. Press Save in the 3D view and the model goes to My projects → 3D models, with your ceiling, light and paint choices. Saving as many 3D models as you like is free.
Which files can I upload?
The .json file HousePlanCraft saves when you press “Save plan” in the plan maker, or “Download” on a saved project. Files from other software are not accepted, because the 3D model is built from HousePlanCraft’s exact walls, doors and windows.
Do I need to draw the plan first?
Yes. Draw it in the free plan maker (or start from a template), save it, then upload the file here. If you are signed in, you can also open any saved project in 3D with one click.
Are the sizes in the 3D model real?
Yes. Everything is built in feet from your plan: 9" walls, a 12'-0" floor to slab, 7'-0" doors, standard furniture sizes, and people at real heights so you can judge the space.
Can I walk inside the house?
Yes. Switch to “Walk inside” to move through the rooms at your own eye height with the keyboard, or with the on-screen joystick on a phone. You can climb the stair to the terrace too.
Can I share the 3D view for free?
Yes, free. Every 3D model has its own link. Share it with chosen people by email, or with anyone who has the link — they can look around without an account. Models you do not save expire after 30 days.
