Patio Enclosures
Patio enclosures are typically structures tied to the back of the house that provides an indoor/outdoor feeling. The main factor that separated them from a room addition is that fact that you cannot use it as a bedroom legally and the amount of light that comes in. Most cities require a minimum of 60% windows and doors. Patio enclosures can be constructed in a variety of materials to complement your house including aluminum, glass, or wood.
