House Floor Plan Generator Free vs CAD and Paid Planners
Reviewed by the OnlineFree.app team · Updated
Key points
- House Floor Plan Generator Free turns a plot size and room wishlist into a to-scale SVG plan with an m² schedule.
- With 0.24 m walls, a 10 × 12 m plot drops from a 120 m² footprint to roughly 109.7 m² of interior.
- It is a schematic sketch utility, not a permit-ready or DIN 277-certified planning service.
- The tool supports 1–2 floors, 1–12 rooms and plots from 3 × 3 m up to 30 × 30 m.
- Verify every room area and local planning rule with an architect before you commit to a build.
What House Floor Plan Generator Free produces
Enter a plot width and depth, add the rooms you want, and House Floor Plan Generator Free returns a labelled 2D floor plan drawn to scale (SVG) plus a room-area schedule in square metres. It runs entirely in the browser on the tool page — no signup, no CAD install, no drawing skill.
The control panel is deliberately small. Plot width defaults to 10 m and depth to 12 m, both adjustable between 3 and 30 m in 0.1 m steps. Floors is a simple 1-or-2 choice, wall thickness defaults to 0.24 m (range 0.1–0.4 m), and the room list accepts 1 to 12 rooms from a fixed set — living room, bedroom, kitchen, bath, hall and similar types — each carrying its own default target area.
The default wishlist is one living room, two bedrooms, one kitchen, one bath and one hall. Change any field and the plan redraws immediately: walls, room labels, room dimensions, door gaps and a scale bar on the canvas, with the schedule beneath showing target m², achieved m² and W×D per room, plus net living area, footprint area and the percentage left over for circulation.
How does it compare to CAD and paid planners?
Compared with CAD software and subscription planning apps, the trade is detail for speed: you get one clean schematic plan in about thirty seconds, and you give up 3D views, furniture libraries, and any output an authority would accept as a drawing set.
CAD earns its place when the plan has to be built — layers, exact dimensions, construction details — but it costs weeks of learning before you can sketch a bedroom. Paid consumer planners sit in between: usually a subscription, often a 3D walkthrough, sometimes a paywall on exporting or printing. House Floor Plan Generator Free sits at the other end: as of 2026 it is free, needs no account, exports an SVG, and uses a deterministic layout engine where the same inputs always produce the same plan.
That narrowness is the point. If your question is "does a 4 × 3.5 m bedroom, a 12 m² kitchen and a 10 m² hall fit inside a 10 × 12 m plot?", a full planner is overkill. If your question is "how will the window reveal look from the sofa?", this tool cannot answer it. And if you are about to buy a subscription from an unfamiliar planning site, running it through Domain Age Checker Online is a cheap check on how long that business has existed. The rest of the OnlineFree.app free online tools follow the same pattern: one job, in the browser, no login.
A 10 × 12 m example in seven steps
A worked example shows where the numbers come from. A 10 × 12 m plot is a 120 m² footprint. With 0.24 m walls around the perimeter, the interior measures roughly 9.52 × 11.52 m, about 109.7 m² — so close to 10 m² disappears into walls before a single room is placed.
Now the steps: leave width at 10 and depth at 12; keep wall thickness at 0.24 m; set Floors to 1; keep the default wishlist of Living 1, Bedroom 2, Kitchen 1, Bath 1, Hall 1; read the plan on the right side of the screen; press Layout variation until an arrangement looks sensible; then read the room schedule underneath.
Those default target areas are typical rather than fixed — say 30 m² living, 14 m² per bedroom, 12 m² kitchen, 8 m² bath and 10 m² hall, totalling 88 m². The remaining ~21.7 m² of interior area appears as circulation leftover rather than as a room. Achieved m² per room shifts with the layout variant you settle on, so read the schedule rather than trusting this arithmetic.
Limits worth knowing before you trust a plan
The tool is upfront about being schematic. Plots are capped at 3–30 m per side, you can plan one or two floors, and rooms come from a fixed list of 1–12 entries. There are no window openings positioned for daylight, no staircase design, no furniture, no plumbing stacks and no structural calculations.
The areas are raw geometry, not certified floor areas. DIN 277 — the German standard for areas and volumes in buildings — distinguishes net floor area, circulation area and construction area in ways this tool does not; the DIN 277 overview lists those categories. Treat the achieved m² column as a fast reality check on your wishlist, not as a figure for a loan application or a building submission.
It also ignores planning law. Site coverage ratios, boundary distances and the permitted ratio of floor area to plot area come from the local Bebauungsplan and the Baunutzungsverordnung, and none of that is modelled here. A layout that fits neatly inside your plot can still be unbuildable under local rules.
What mistakes ruin a first layout sketch?
The most common mistake is treating the footprint as usable space. On a 10 × 12 m plot, 0.24 m walls remove roughly 10 m² of interior before anything is drawn; thinning them to 0.1 m to "win" area just produces an unrealistic exterior wall that no builder would price.
The second is over-listing rooms. Twelve rooms inside 109.7 m² averages about 9 m² each before circulation, which is why the leftover percentage in the schedule matters. Halls, landings and door swings eat a real share of any plan, and a leftover figure close to zero usually means rooms are too small or awkward to reach.
Third, do not confuse achieved m² with habitable area — a hall counted in the schedule is not a bedroom. And do not treat the first attractive-looking variant as settled: the Layout variation button exists precisely because the opening arrangement is rarely the best one, and because seeing three alternatives makes the architect conversation far more concrete.
Frequently asked questions
Is House Floor Plan Generator Free really free, and do I need an account?
Yes — House Floor Plan Generator Free is free and needs no account, email address or subscription. The layout engine runs in your browser, so the plan recomputes as you type and the input data is not uploaded to a server. You can open it, sketch a layout, screenshot the result and close the tab without leaving personal data behind.
Are the plans from House Floor Plan Generator Free permit-ready or DIN 277-compliant?
No. The tool produces a labelled schematic plan, not submission documents. It performs no structural calculations, positions no windows or stairs, and its areas are raw geometry rather than DIN 277-certified floor areas. Treat the output as a briefing sketch for an architect, who must produce the permit-ready drawings and confirm the local building rules.
Can I use House Floor Plan Generator Free on a phone?
Yes. On a phone the interface stacks vertically — inputs first, then the plan, then the schedule — and the plan can be fitted to the viewport width. Numeric fields open the number pad, steppers use 44 px tap targets, and the room schedule scrolls sideways. A desktop screen is still more comfortable for comparing layout variants.
How accurate are the square-metre figures in the room schedule?
The figures are as accurate as your inputs. Areas are computed from the plot dimensions, wall thickness and the layout variant you choose, so a 10 × 12 m plot with 0.24 m walls yields roughly 109.7 m² of interior area rather than 120 m². Read the room schedule instead of estimating, and verify anything important with an architect.
Can House Floor Plan Generator Free plan a two-storey house?
Yes, up to two floors. The Floors selector offers 1 or 2 and the plan is redrawn for the option you pick, from the same plot dimensions and room list. The tool does not design staircases or check headroom, so on a two-storey sketch you should mark where the stairs would go yourself before discussing the layout with a planner.
