Yikes! 5 bathrooms! There for a few minutes, I was worried about the female "Billybobs" in your home! LOL!!
In 1955, my mother added a laundry room and a powder room.
When I planned the renovations in 1994, I gave every bedroom its own bathroom, plus other renovations. My latest project is to close in one of the six outside decks to create a broadcast studio in the house, with a glass wall, an 80-mile view, and a fireplace. LOL.
