Tiang: Home Design 3D Planner

Tiang is a home design app with something no other has: real building-physics simulations that run on your own floor plan. Draw your home in 2D, see it in 3D, then simulate its temperature, humidity, electricity and Wi-Fi — right on your phone or tablet.

Most home design and floor plan apps stop at how a room looks. Tiang shows you how your home will actually perform, before you build, buy or renovate.

DESIGN YOUR HOME — FREE
- Draw rooms and walls in 2D that snap neatly into place, then switch to 3D
- Stack multiple floors and add roofs, doors, windows and furniture
- Choose wall materials and construction to match your real home (US and EU building systems)
- Lay out electrical wiring, panels, air conditioning, plumbing and rooftop solar

SIMULATE HOW IT REALLY PERFORMS
- Temperature — see indoor heat as a live 3D heat-map, room by room, driven by real local weather and the sun moving across the day
- Humidity — find where your home gets damp, with condensation and mould risk highlighted room by room
- Electricity & solar — model your electricity use, rooftop solar, battery and running costs with an animated power-flow, for grid, hybrid or off-grid homes
- Wi-Fi coverage — place your router, mesh and access points and see the signal and speed in every room across 2.4, 5 and 6 GHz, so you can clear dead zones

SEE IT, SAVE IT, SHARE IT
- Play back a full day, month or year as a timelapse
- Export a clean PDF report of your design and simulation results
- Sign in with Google to keep projects synced across your devices
- Share a project with people you invite
