A basement is the perfect location for the extra family living area, such as an entertainment room or playroom. It is also an excellent place to rearrange the boiler, utility room, and storage, making more precious room on the ground surface.
Also, a basement can have its very own entrance, thus becoming a self-contained unit. This can be the perfect location to convert into a home office. However, if you wish to convert the basement into a separate dwelling, you will need to gain express consent.
