PELES MANSION  (13,739 sq ft)
Peles Mansion is my miniature version of Peles Castle in Romania, whose floor plan is also featured on this site.  Mine certainly has plenty of room too.  It's 8,384 square feet, with an optional upstairs studio and finished basement that can bring the total to 13,739 square feet!!  Besides having a main level and an upper level family room, there is a library with a spiral staircase tower down to the pub or rathskeller.  Next to that is a billiards room, game room, and drawing room, all of which have access to the torch lit inner courtyard.  And from there, you can pass underneath the family room to access the back terrace and swimming pool.  The extensive master suite on the second floor has massive windows overlooking the courtyard.  The main tower in front has stairs up to a loft, and further up, the tower room.
