Cole, they indeed did have to install a high capacity vent fan with roof mounted blower, and built in fire extiguishing system. Walls surrounding are ceramic tile.
The house it was located in was very unique - a contemporary built in 1954, with lots of steel, concrete and glass. It was remodeled and expanded in the early 80's, and is approximately 6000 sq. ft. on two levels. It is built on a hillside, so the lower level opens out to the back. The kitchen is on the upper level.
I do remember it being nice and warm in winter in there. Summer wasn't bad because the house is in a wooded area, so not a lot of heat gain from the sun. And of course it is air conditioned.
I've not been in that house since the 90's, when Brenda moved. I don't know the people who live there now, so have no idea if that range is still there.
