Sunroom: This room -- also called a solarium or conservatory -- is a glassed-in living space typically attached to the house and accessible from indoors. It is designed to function as additional living area during mild weather but may be too hot or cold in the heart of summer or winter.
Four-season room: Closely related to the sunroom, this option is designed to be heated and cooled. As a result, it can be enjoyed year-round.
Attached greenhouse: Featuring the same basic structure and shell construction as a sunroom or four-season room, an attached greenhouse structure offers light, temperature, and humidity levels that are designed for plants, not humans.
Screen room or porch: This option has walls constructed of mesh rather than glass, which offers the advantage of fresh air without insects. Like the sunroom, it is habitable only when the weather is agreeable. It makes a terrific budgetary choice.
