Older buildings may require asbestos or lead removal. Additional considerations include flooring options, changes in lighting and window treatments, and changes in paint colors on the wall to accommodate projectors, videoconferencing, or distance learning. Furniture. Computer hardware requires desks and chairs that have been ergonomically designed to meet the unique physical demands of the equipment. Keyboards may need lowered trays and precautions should be taken to place monitors to avoid eye strain. Consideration should also be given to storage.

Also, student bookbags and other belongings may not fit under computer desks and may require additional storage elsewhere in the room.
