The Carlisle Estates are ~6 hours outside of Amber City on horseback. The House is rather large, but always feels full, with much of the Pinegar's extended family in residence with many of their friends at any given time.
The central mansion was built by the first Duke of Carlisle, Howell Carlisle, some 8 generations ago. Through time the West and East wings were added, as well as guest cabins which dot the forest near Hanks Pond.
The Ballroom originally built into the back of the central house was expanded by the 7th Duke of Carlisle. Expensive glassed doors were added along the outer walls and along the back wall and 2nd level gallery. When the doors are open it gives the lower level of the ballroom the illusion of being nearly wall-less. It also greatly improves the temperature during warmer gatherings. The gallery is set against the back wall, and opens onto a large balcony overlooking the grounds. The stairs and walkways to the gallery begin against the inner wall, so as to leave the glass doors uninterrupted. The walkways along the 2nd level of the outer walls are wide enough to allow guests to stand all along the railing and see most of the ballroom.
Balls at Carlisle are known to be excellent opportunities for people-watching. The Duke's nieces and nephew have been known to lay in wait on the walkways for hours until some unsuspecting soul walks under them, only to be assaulted by falling water, confetti, or petals. Abalene Pinegar once managed to tie a line across the ballroom, from one walkway railing to the other. The children then practiced crossing the room on it until they were caught.
On Earth, in a place called Ireland, in their County of Kildare, you can see a shadow of the Carlisle Estates here - start in the entrance hall.
