Historic renovation of a glass conservatory built at a Vanderbilt mansion.  The mansion and Palm House are currently owned by Dowling College on Long Island, NY.

 

The old vent holes were used to create a ring of decorative light around the structure at the base of the hip roof.  Post-top lights were added.  Track fixtures were mounted at the apex of the roof to provide the best glare-free aiming angles (for example to light a speaker at a podium).
