In the basement, you can place pantries, utility rooms, boiler room, garage for a car or a motorcycle. The height of the basement should be at least 1.9 meters. It is not allowed to place living rooms in basements, but if you wish, you can equip a very beautiful room and in the basement. But it is necessary to take into account the problem with the light, since the basement in the basement is small, so you need to find an alternative to daylight.
