Planning a tiny home requires extreme precision where every inch counts. Whether you are building on a dual-axle trailer or a fixed foundation, visualizing the circulation and furniture placement is the first step toward a functional home. Our AI-powered tool takes your specific dimensions and desired zones—like lofts, wet baths, and compact kitchens—and generates a conceptual 2D layout to help you see how your lifestyle fits into a small footprint.
How to generate your tiny house layout
Define your dimensions
Start by entering the exterior length and width of your tiny house, such as 24x8.5 feet for a standard trailer-based build.
List your essential zones
Describe where you want the bathroom, kitchen, and sleeping areas located relative to the main entrance door.
Generate the SVG plan
Click generate to see a to-scale 2D floor plan including walls, windows, and furniture placements rendered instantly in your browser.
Refine and save
Review the circulation paths and clearances, then download your conceptual layout for your mood board or builder discussions.
Mastering Small Space Design and Circulation
Designing a tiny house is an exercise in efficiency and multi-functional furniture. Most tiny houses on wheels (THOWs) are limited to 8.5 feet in width to avoid special road permits, making the internal 'clear' width roughly 8 feet after insulation and wall framing. When planning your layout, prioritize the 'wet zone'—the kitchen and bathroom—by grouping plumbing together to simplify construction and weight distribution. A standard tiny house bathroom usually requires at least 30 to 36 inches of depth for a functional shower and toilet. Circulation is another critical factor; ensure you have at least 24 inches of clear walkway space to avoid a cramped feeling. For sleeping lofts, remember to account for head height and the placement of the ladder or storage stairs, which typically consume 18 to 24 inches of floor width. Our generator helps you visualize these constraints in a to-scale format, allowing you to experiment with different orientations before committing to a final design.
Frequently asked questions
Is this tool really free to use?
Yes, FloorPlanMaker is completely free and requires no signup or account. We operate on an hourly fair-use limit per IP address to ensure all users can access the AI generator.
Can I use these plans for building permits?
No, these are conceptual 2D floor plans intended for space planning and visualization. They are not architectural blueprints, engineering documents, or permit-ready CAD files.
What dimensions should I use for a tiny house on a trailer?
Common lengths range from 18 to 32 feet, while the standard width is 8.5 feet. When prompting the AI, use these exterior dimensions to get the most accurate scale for your layout.
Can the AI handle lofts and mezzanines?
The generator produces a 2D top-down view. You can describe lofts in your prompt, and the AI will illustrate the ground floor layout and the footprint of the loft or stairs to show how they interact with the main living area.
