In House Build 3D you have invented a new way to quickly build walls in houses. You will complete the construction of houses on each level. The roof, supports for it, doors and roofs have already been installed; all you have to do is fill the empty spaces on the wall by moving a special block. It will leave behind a dense mass that quickly hardens and forms a wall. By filling it in on all four sides of the house, you will receive a finished home that you can move into and live happily in House Build 3D. The game allows you to hold a block twice in the same place.
