Build a house online, block by block
Design a house in 3D straight from your browser: lay the floor, raise the walls, add a pitched roof and a garden. BLOX is free and nothing needs installing.
Play BLOX freeSee community builds →Start with the floor plan
Pick a build plate and lay out the rooms with flat blocks. Grass, sand, stone or snow terrain sets where your house stands.
Walls, windows and roofs
Stack brick, wood or stone blocks for the walls and leave gaps for doors and windows. Slopes and ramps make pitched roofs; arches make doorways and porches; domes and cylinders give you towers and chimneys.
Garden, pool and street
Water blocks make a pool or pond, sphere and cone blocks make trees and bushes. Go big on a 96 × 96 plate and build the whole street.

FAQ
Can I build a house online for free?
Yes. BLOX is free with no ads. Open it in your browser and start building.
Is it like a home design app?
It's a block building game, not an architecture tool. It's quick, playful and good for houses, castles, cabins and whole towns.
Do I need to sign up?
No. You can build as a guest. A free account saves your builds and lets you share them.
