20×30 House Plan — Free AI Generator
A 20 × 30 ft plot — 6.1 × 9.1 m, about 600 sq ft — is a small site, and small sites reward planning more than large ones do. Every foot given to a corridor is a foot taken from a bedroom, so the layouts that work here are the ones with almost no circulation at all: rooms opening off a single living space rather than off a hallway.
Tell HousePlanAI you have a 20 × 30 plot and roughly how you live, and it drafts a full plan for that footprint — walls, doors, windows, room names and areas, and the boundary wall around the plot. From there nothing is fixed. Drag a wall to steal a foot from the living room for a wider bathroom, and every dimension and area on the drawing updates as you do it.
What fits on a 20 × 30 ft plot
| What you want | Floors | How it works out |
|---|---|---|
| 1 bedroom, living, kitchen, bathroom | Single floor | Comfortable — the layout that fits this plot most easily. |
| 2 bedrooms, living, kitchen, 1–2 bathrooms | Single floor | Works if the second bedroom is compact and rooms open off the living space. |
| 3 bedrooms | Two floors | Needs a staircase, which costs floor area on both levels. |
The table above is a starting point, not a rule. What actually fits depends on how much of the plot you can build on, and that is set by the setback and coverage rules where you live — HousePlanAI does not know them and does not check them, so confirm them locally before you build.
On a plot this size the two decisions that matter most are where the stair goes, if you want a second floor, and which side the road is on. Both change the whole layout. You can tell the copilot both, generate a plan, and if you do not like where it put the stair, move it and see the 3D view rebuild around your change.

How many bedrooms fit in a 20×30 house plan?
One or two bedrooms fit comfortably on a single floor of a 20 × 30 ft plot. Three bedrooms generally need a second floor, and the staircase itself takes floor area away from both levels.
Is HousePlanAI free?
Yes — HousePlanAI is free to use right now. You can generate a plan, edit every part of it, walk through it in 3D and download a PDF plan sheet without paying anything. Paid plans may arrive later, but nothing you can do today is behind a paywall.
Can I edit the floor plan the AI creates?
Yes. The AI's plan is a starting point, not a finished answer. Every wall, door, window and room is yours to move, resize, delete or rename, and the dimensions and areas update as you go.
Can I see my house in 3D?
Yes. Any plan can be viewed as a 3D model with walls, floors, doors, windows and furniture in place. You can take a guided walk in from the street or move through the rooms yourself, and every edit you make in 2D shows up in 3D straight away.
What plot sizes does it support?
Any size. Common sizes are one tap away in both feet and metres — 20×30, 30×40, 30×50 and 40×60 ft, or 9×12 and 10×15 m — and you can type your own width and depth instead. Switch between feet and metres whenever you like.
Can I download my plan?
Yes. You can download an A3 PDF plan sheet with dimensions, room areas and a title block, or export the drawing as an image. You can also copy a share link that opens the plan in anyone's browser — no account needed on their side.
Do I need an account?
No. Open the app and start describing your house straight away — no sign-up, no email, no card. An account is only useful if you want your plans saved to the cloud so you can pick them up on another device.
