Free floor plan software: what is actually worth using
Search for floor plan software and you get three kinds of result: professional CAD you will not learn in a weekend, interior-design apps that are really about furniture, and sign-up walls. Here is what each kind is actually for, so you can pick by what you are trying to do.
What are you actually doing?
| Your goal | What you need |
|---|---|
| Work out a layout for your own house | A fast 2D plan editor with real dimensions |
| Show a mason or contractor what you want | A dimensioned 2D plan you can print |
| Get municipal sanction | A licensed architect — no DIY tool qualifies |
| Decorate a room you already have | An interior/3D design app |
| Produce construction drawings | AutoCAD, Revit or an architect who has them |
The categories
- Professional CAD (AutoCAD, Revit, ArchiCAD): exact and complete, expensive, and a real learning curve. Free only as a student licence.
- 3D home design apps: good for visualising finishes and furniture, weaker at precise wall dimensions and setbacks, and most gate export behind a paid plan.
- Browser 2D plan editors: fastest route from "I have a 30 × 40 site" to a dimensioned layout. Limited to 2D, which for deciding a layout is what you want anyway.
- Free-with-a-catch: watermarked exports, project limits, or a card required before you can download what you drew. Check the export terms before you invest an evening in a drawing.
What this tool does
HousePlanCraft is a browser 2D plan editor built for Indian house plans. Rooms share walls and resize together, dimensions are in feet and inches, plot size and setbacks are first-class, doors and windows snap to walls, and there is a Vastu checker that works zone by zone against the facing you set. Drawing and the Vastu check need no account. A free account — no card, no paid tier — lets you export the sheet as PNG or SVG, or the plan as JSON, and keeps each plan as a project with a thumbnail you can come back to.
What it is not: it is not CAD, it does not do 3D, and it does not produce sanction drawings. It is for getting the layout right.
Questions worth asking of any free plan tool
- Can I export what I draw without paying, and without a watermark?
- Does it work in feet and inches, or only in metres?
- Does it understand plot setbacks, or just rooms?
- Do walls have thickness, and do adjacent rooms share them?
- Does my work survive closing the tab?
Frequently asked questions
What is the best free software to draw a house plan?
For working out a layout, a browser-based 2D plan editor is the fastest option and needs no installation. For construction drawings you need CAD, or an architect. Match the tool to the job rather than looking for one tool that does everything.
Can I design my own house plan without an architect?
You can design the layout yourself, and doing so before you hire anyone usually saves money and revisions. You still need a licensed architect or engineer for structural design and for the drawings your local authority will sanction.
Is there free floor plan software that works on a phone?
A browser-based editor runs on a phone, though drawing precise walls is far easier on a laptop or a tablet. Sketch on the phone, refine on a bigger screen.
