Temperature control is a concern when finishing your basement, due to the fact your basement is cooler than the rest of the house. Adding air ducts or extra insulation will help maintain a comfortable temperature.
If you choose to add new flooring, there are several options to consider. Carpet is a popular choice, because it is warmer than a tile floor. However, the downside is that carpet holds moisture and can mold. Also, if you have a leak upstairs that ends up in the basement, your carpet can be costly to clean or replace. Tile and linoleum are among some of the easier-to-maintain options. They are easy to clean. and though they may not provide a warm floor, area rugs can be used to combat the chill.
If you are planning on using your new space regularly, adding a bathroom will prove to be a big convenience. A small kitchen also can come in handy, especially if the basement will be used as a guest room. If this is a task you are considering, you may want a contractor to help you, because pipe work and electric work may be required.
Basements often do not have much lighting. Additional lights can brighten your space and set the tone for your room. They can accent game tables and also can include a dimmer for a home theater. Adding windows or glass doors will not only provide extra lighting and make the space look larger, but act as extra exits in case of fire or other emergency, as well.
