It is not uncommon for people to want to buy a home that has a large basement underneath the structure. Even though this might need a lot of work it will be up to them what they want to do with it. For some people it is a convenient storage area for boxes. For others it is a potential space that they can use when trying to create a home gym or a spare bedroom.
The first thing that you will want to think about when trying to design this space is the type of temperature control that it has. Most of the time these types of rooms are quite cold and very damp. This puts them at risk for condensation and leaks all over the walls and ceilings.
You should think about adding in its own central heating and possibly a small ceiling fan for the summer months. In that way you will be able to use the heating to keep things comfortable and to prevent anyone who steps inside from freezing out too quickly.
Lighting is always necessary and most of us love the idea of having it come from the natural sunlight. However, in this room that it is not going to be at all possible. Think carefully about what type of room you will be putting together. If it is a bedroom than you might want to have a few tall lights scattered around the corners. You should also consider one or two ceiling lights.
Colors can either make or break a space inside of your home. You want to make sure that you are going to go with colors that help to create the type of atmosphere that you love. For example, if you are using the spare bedroom basement design than you should stick to using neutral or light colors. Dark colors will make the space smaller.
