It takes about two to three days to demolish a house. The process usually starts with the removal of the roof, followed by the demolition of the walls. Finally, the floor is demolished.

The amount of time it takes to demolish a house can vary depending on the size and structure of the house. Typically, it will take anywhere from a few hours to a few days. However, more complex houses or houses with extra features (like a chimney or tower) may take longer to demolish.
