Solarium or Greenhouse
Design Requirements:Year-round functionality.
For all glass structures such as a solarium or a greenhouse, an opening glass wall provides maximum functionality for large exterior openings. During winter months, where heat gain is desired, the room can be closed and be weather tight, but during summer months when an exterior space with cover is desired, the wall can be partially or fully opened for degrees of separation or openness. One example is a circular solarium.

Using the same concept as above, a greenhouse or rectilinear solarium offers similar functionality -- whether outside --
or inside
