uh, yes. It's poorly insulated, but completely walled off from the elements. It gets REALLY warm when the sun hits it (which sucks int the summer, good in the winter), and pretty cool at night (reversed on the summer/winter thing - but completely doored/windowed off from the main portion of the house when i want). but lots of sun during the day for my plants.
just finished remodeling it, so i happened to have a picture on hand
