Solarium
A solarium was a type of structure designed to let in ample sunlight.

In 2373, the New Essentialists staged a raid on a solarium in the resort located at Temtibi Lagoon on Risa, so as to demonstrate the vulnerability of the Federation. ()

Shortly before Ezri Dax's visit in 2375, the Tigan family installed a new solarium in their house on Sappora VII, with tiles brought in from Andoria. ()
