KD, I was like you...I thought the house was modest size too. It looked like a nice size home from the outside but not huge. It is in fact larger than I thought. The news said yesterday that it's 15 bedroom home and has three floors. They showed a layout of it and of course a tour of the house...it was big.
BTW, I called that room a wine cellar because some people refer to it as that...I know it wasn't actually used to store wine. I was just pressed for time and it was quicker for me to type it that way instead of boiler/utility room...lol
