Design Your House in 3D Online
Free, No Download, Built for Real Construction

Draw your floor plan, switch to 3D, and walk through your home before a single board is cut — all in your browser, completely free. Unlike a generic room planner, Geoniks is built specifically for timber construction: real lumber dimensions, real wall systems, and a real cost estimate calculated from your actual design.

What makes Geoniks different from a generic 3D house planner?

Most free online house design tools are built for visualizing furniture and room layout — useful for interior planning, but they don't know a 2×4 stud wall from a log wall, and they can't tell you what your design will actually cost to build. Geoniks is built around real timber construction: standard frame, log, timber frame, post & beam, and CLT wall systems, real US lumber sizing, and regional wood pricing. The design you draw isn't just a picture — it connects directly to a materials list, a cost estimate, and a manufacturer quote request.

How does the 3D house design process work?

  1. Start from a blank plan or a ready-made template (Hygge, Wood Cabin, Chalet, Riverside Cottage, and more).
  2. Draw walls, doors, windows, roofs, stairs, and porches — room areas calculate automatically as you close each loop.
  3. Switch to 3D at any time and walk through the design in first-person, WASD to move.
  4. Choose your wall construction system and paint every surface — walls, roof, floor, fence — with real wood, marble, or granite finishes.
  5. Review the automatic materials cost breakdown and basic code check.
  6. Request a quote directly from your finished design.

Designing a house for your specific land

If you already have a plot, Geoniks' Plot Analyzer lets you upload a cadastral map, satellite image, or hand-drawn sketch, draw your plot boundary directly on it, and get an instant starting-point regulation check — setbacks, coverage ratios, and how many floors you can build — for 100+ countries, along with a template sized to fit. It's a planning tool, not a substitute for a licensed local professional's final approval.

Frequently Asked Questions

What is the best free 3D house design tool?
It depends on what you're designing. General-purpose room planners are fine for rearranging furniture in an existing space, but if you're actually planning a build — a wood house, tiny house, cabin, or bungalow — you need real lumber dimensions, wall construction systems, and a genuine cost estimate, not just a pretty render. Geoniks is free and built specifically for timber construction: it calculates real materials lists and regional wood pricing, not just a visual model.
Can I design a house online without downloading software?
Yes — Geoniks runs entirely in your browser, on desktop or mobile, with nothing to install. You draw your floor plan, switch to 3D, and walk through the design in first-person, all in the same browser tab.
Do I need architecture or CAD experience to design my own house?
No. Geoniks is built for homeowners, not architects — draw walls by clicking points on a 2D grid, place doors and windows, and room areas calculate automatically. You still want a licensed engineer or architect to review and sign off on the final plan for code compliance, but the design process itself doesn't require professional CAD skills.
What's the difference between Geoniks and a generic room planner app?
Generic room planners are built for visualizing furniture layout and general floor plans — they don't know the difference between a 2x4 stud wall and a log wall, and they don't calculate real construction costs. Geoniks is built specifically around timber construction: real lumber dimensions (2x4 to 2x12, heavy timber), multiple wall systems (standard frame, log, timber frame, CLT), regional wood pricing, and a manufacturer quote marketplace — the design connects directly to an actual build, not just a picture.
Can I use my land/plot to design a house that fits local regulations?
Yes — Geoniks' Plot Analyzer lets you upload a plot map or satellite image, draw your land boundary, and get a starting-point check of building regulations (setbacks, coverage ratios, floor-count limits) for 100+ countries, plus a template recommendation sized to fit. It's a planning starting point, not a substitute for a licensed local professional's final sign-off.
