Design Your Tiny House in 3D
Free Floor Plan, Cost Estimate & Builder Quotes

A tiny house is a fully functional home, usually under 400 sq ft (37 m²), built to maximize every inch of space. With Geoniks you draw the floor plan, see it in real-time 3D, get a real timber construction cost estimate, and request a quote from a tiny house builder — free, directly in your browser.

How much does it cost to build a tiny house?

Most tiny houses cost between $30,000 and $80,000to build, depending on size, materials, interior finish level, and whether it's built on a trailer or a permanent foundation. Wood-frame construction is typically the most cost-efficient option for a structure this size — lighter framing, faster assembly, and lower foundation requirements than concrete or steel. That range is a planning estimate, not a quote: your actual cost depends on your specific floor plan, lumber grade, and region. Draw your design in Geoniks and the cost estimator calculates a real breakdown from your actual materials list, not a generic average.

How do you design a tiny house?

Start with how the space will actually be used — sleeping, cooking, and storage all compete for the same few hundred square feet, so layout decisions matter more in a tiny house than in a larger home. In Geoniks:

  1. Open a tiny house template or start from a blank plan.
  2. Draw your walls, doors, and windows — room area is calculated automatically as you close each loop.
  3. Switch to 3D and walk through the design in first-person before anything is built.
  4. Choose your wall construction system (standard frame, timber frame, or log) and materials.
  5. Review the automatic cost estimate and code check.
  6. Request a quote from a matched tiny house builder.

Tiny house regulations and permits

Rules for minimum habitable area, ceiling height, egress windows, and whether a tiny house qualifies as a permanent dwelling or an RV vary significantly by country, state/province, and municipality. Before finalizing a design, check your local building department — Geoniks Plot Analyzer gives you a starting-point regulation check (building limits, setbacks, floor-count allowances) for 100+ countries, but it doesn't replace a licensed local professional's sign-off on your final plan.

Tiny house on wheels vs. tiny house on a foundation

A tiny house on wheels (THOW) is built on a trailer chassis and is often classified as an RV rather than a permanent residence — this can mean fewer building-code hurdles, but different rules for insurance, financing, and where you're allowed to park it long-term. A foundation-built tiny house is a permanent structure and falls under standard residential building codes, similar to a small conventional house. Which one makes sense depends on your land, how permanent you want the home to be, and local zoning.

Frequently Asked Questions

How much does it cost to build a tiny house?
Most tiny houses cost between $30,000 and $80,000 to build, depending on size (typically 100-400 sq ft / 9-37 m²), materials, and whether it sits on a foundation or a trailer. Wood-frame tiny houses are usually cheaper per square foot than concrete or steel builds because the structure is lighter and faster to assemble. Geoniks gives you a real cost estimate based on your actual design and choice of lumber, not a generic average.
How small can a tiny house legally be?
Minimum size rules vary by country and even by municipality — some places set a legal minimum habitable area, others regulate tiny houses on wheels differently from those on a permanent foundation. Always check local building codes and zoning before finalizing a design; Geoniks Plot Analyzer gives you a starting-point regulation check for 100+ countries, but a licensed local professional should confirm final compliance.
Can I design a tiny house myself without an architect?
Yes — a tiny house small footprint and typically standard construction make it one of the most approachable house types to design yourself. Geoniks lets you draw the floor plan, place walls, doors, and windows, and see a real-time 3D model, without needing CAD experience. For code compliance and structural sign-off, you will still want a licensed engineer or inspector to review the final plan.
What is the difference between a tiny house on wheels and one on a foundation?
A tiny house on wheels (THOW) is built on a trailer chassis, is typically classified as an RV rather than a permanent dwelling, and can be relocated — this often means fewer building-code hurdles but different insurance, financing, and parking rules. A foundation-built tiny house is a permanent structure subject to standard residential building codes. Which one fits depends on your land, local zoning, and how permanent you want the home to be.
How do I get a manufacturer to build my tiny house design?
Once your design is finished in Geoniks, you can request a quote directly from your 3D model — the request is routed to tiny house builders and timber suppliers matched by region and wood type, and they respond with their own price. There is no bidding war and no middleman markup.
