30×40 House Plans (1,200 sq ft) — Free AI Naksha Generator
A 30 × 40 ft plot — 9.1 × 12.2 m, 1,200 sq ft — is one of the most common residential sizes anywhere plots are measured in feet, and it is a genuinely comfortable one. There is room for a proper living space, a kitchen that two people can stand in, and bedrooms that take a real bed and a wardrobe without the door hitting either.
Describe your household to HousePlanAI — how many bedrooms, whether you want a separate dining area, which way the road runs — and it drafts a plan for the 30 × 40 footprint with rooms sized and connected, doors and windows placed, and the plot's boundary wall drawn. Ask for a second floor and you get one, with a staircase between the two and the stairwell cut through the slab above.

Example 30 × 40 ft plan
What fits on a 30 × 40 ft plot
| What you want | Floors | How it works out |
|---|---|---|
| 2 bedrooms, living, dining, kitchen, 2 bathrooms | Single floor | The most comfortable single-floor layout at this size. |
| 3 bedrooms, living, kitchen, 2 bathrooms | Single floor | Fits, but the third bedroom and the living room both give up some space. |
| 3–4 bedrooms, plus a separate family area | Two floors | Roomy — the usual choice when a growing family plans ahead. |
How much of those 1,200 sq ft you can actually build on depends on the setback and coverage rules in your area, which vary widely and which HousePlanAI does not check. Look them up before you commit to a footprint; the plan is easy to shrink once you know the number.
If you are unsure between one floor and two, generate both. Each takes about a minute, and seeing the two-storey version in the 3D walkthrough — standing in the upstairs hallway, looking down the stair — tends to settle the question faster than comparing two drawings does.
Whether you call it a floor plan or a ghar ka naksha, it is the same drawing: every room at its real size, on the real plot, with the walls where they would actually stand.
Setbacks and buildable area on a 30 × 40 ft plot
Left to its own defaults, HousePlanAI keeps 8 ft of open ground at the front of a 30 × 40, 3 ft at the back and 3 ft down each side, so the sides and rear stay clear enough to ventilate and the approach to the front door is not the road. That leaves a buildable envelope of about 24 × 29 ft — roughly 696 sq ft of footprint per floor out of the plot's 1,200.
Tell it you own a car and the front tightens to 5 ft, because the car now has a bay of its own drawn at a front corner instead of a strip of empty ground running the width of the house. The envelope grows to about 24 × 32 ft, near 768 sq ft a floor.
Those are HousePlanAI's numbers, not your municipality's. Setback, coverage and floor-area rules differ from one city — sometimes one street — to the next, and the generator neither knows them nor checks them. Find out what applies to your plot first; then describe the footprint those rules leave you and the plan is drawn to that instead.

East facing, west facing, north facing and south facing 30 × 40 plans are the same plot turned a quarter turn, not four different houses. The first number is always the frontage — the edge the road runs along — so a 30 × 40 keeps its 30 ft face to the street whichever compass direction that street points. Say which way yours faces and HousePlanAI rotates the plan, puts the gate and the main door on that side, and places windows accordingly. There is no separate page here for each facing because there is no separate plan.
A 30 × 40 duplex, or G+1, is the usual answer when four bedrooms are wanted on a plot that fits three. Two floors on this envelope come to roughly 1,322 sq ft of built-up area, minus what the staircase takes out of each level. Ask for two floors and the stair, the landing and the stairwell opening in the slab above are all drawn, and the 3D walkthrough will take you up them.
Parking works at this width. One car needs about 9.5 ft of clear width and 15 ft of length; drawn at a front corner of a 24 ft-wide envelope it leaves roughly 14.5 ft of house across the front row, which is enough for the entrance and a room beside it. Two cars want about 16 ft side by side and are a genuine squeeze on a 30 ft frontage — possible, but the front of the house becomes mostly bay.

How many square feet is a 30×40 plot?
A 30 × 40 ft plot is 1,200 sq ft, or about 111 m². The area you can build on is smaller than that, because most places require you to leave open space around the house — check your local rules.
Can I fit a car in a 30×40 plan?
Yes, one car comfortably. A single bay needs about 9.5 ft of width and 15 ft of length, and HousePlanAI draws it as open ground at a front corner of the house with the compound wall left open across it. On the roughly 24 ft-wide envelope a 30 × 40 leaves, that still leaves about 14.5 ft of frontage for the entrance and the room next to it. Two cars need about 16 ft side by side, which is tight on a 30 ft frontage.
Is 3BHK possible on 30×40?
Yes. Three bedrooms fit on a single floor of a 30 × 40 — the buildable envelope with HousePlanAI's default setbacks is about 24 × 29 ft, near 696 sq ft — though the third bedroom and the living room both give up some space to make it work. If you want three generous bedrooms plus a separate dining room, ask for two floors instead.
What does a 30×40 house cost to build?
Approximately ₹13–17 lakh for a single floor on this plot, and ₹25–31 lakh for a G+1 duplex. Those are rough figures for India, state capitals and large cities — the app's default Indian rate of ₹1,800 per built-up sq ft at standard quality — and they cover structure, flooring, doors and windows, wall finishes and the compound wall. Costs move a long way with the city, the specification and the finish; the cost panel in the app re-prices your own plan for your own region and lets you type your builder's rate over ours.
Is HousePlanAI free?
You can start without a card and without an account: describe your house, generate a plan and look around it in 2D and in 3D. A free account is optional, and what it gives you is your plans kept in the cloud rather than only in this browser. If a price applies to anything beyond that, you will see it before you pay, and it is one payment rather than a subscription.
Can I edit the floor plan the AI creates?
The AI's plan is a starting point, not a finished answer. Every wall it draws is a real object with real dimensions rather than a line in a picture, so the rooms and areas are the ones you would actually get. If it is not the house you pictured, change your brief and generate again. Reworking the drawing itself comes with full access; if a price applies, you will see it before you pay, and it is one payment rather than a subscription.
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 the model is built from the plan itself, so it always shows the house as currently drawn.
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?
A finished plan can leave the browser three ways: as an A3 plan sheet — a PDF with dimensions, room areas and a title block — as an image of the drawing, or as a share link that opens the plan in anyone's browser. Opening a link someone sends you is always free, with no account on their side. If a price applies to taking a plan out, you will see it before you pay, and it is one payment rather than a subscription.
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.
