The house was heated with oil boilers then thru a forced air system. There were grills in the floor underneath just about all the 42, French windows 14 foot high on the first floor. (The ceilings on the 1st floor were 18 feet high). There were no return grills in the house. Outside air was drawn in from grills outside near the South terrace and forced over steam radiators in the furnace room then sent to all the rooms. The positive pressure in the house forced the air up the 15 fireplaces to give a nice fire. Air was also forced out cracks or any openings in the windows to prevent cold air from coming in. One could stand near any of the windows and there would not be a draft. The house was not air conditioned. There was a 10,000 gallon oil tank under the front lawn to feed the furnace.
When Hollywood wanted to film the Great Gatsby in 1974, they wanted to use Rose Terrace in the movie. At that time, the bank was still in control and denied the use of it. Hollywood then used "Rosecliff" in Newport, RI for the ballroom scene.
The Developer who bought Rose Terrace wanted to make Condominiums out of it and add a few more buildings on the property. After a couple of years, economic conditions were not right and also not taking care of the building, (low or no heat, etc). the roof and walls leaked, and streaked the ceilings and walls, it was then decided to develop the property as single family homes. "Rose Terrace" was demolished in 1976.
