Summarize this article:

Start by clearing the area of any items or objects that you do not want to get dusty. Box them up and put them in another room in your home or in a storage unit. Leaving them in the space will only allow them to collect dust during the demolition and remodeling. You should also remove small furniture and decorative items on the walls so they do not get dusty. If there are items of furniture that have to stay in the space or cannot be moved, make sure you cover them with thick tarps or sheets. Use tape to attach the tarps or sheets to the bottom of the furniture so they are fully covered and protected from dust. Close all the doors in the space except one. You can use the one open door as the sole entrance and exit. Keep all the other doors closed so dust can not blow out into other areas of your home. Tape the doors shut, sealing them on the top and bottom, so the dust is contained.
Remove personal items and objects. Cover furniture in the space with thick tarps or sheets. Have one door open as the only entrance and exit.
