That is a full size Equestrian Arena for the Horses with what looks like Jumps and Gates among other things. Hell I would take the Barn! 6 stalls fully Climate controlled with a complete live in Apartment built above the Stables. Not too mention the Great Danes would love the Commercial grade glass door elevator on the inside of the house, No stairs! They would be even more spoiled than they are now. LOL :dog:
