A central atrium 30 stories tall, roofed with glass and papered in gold leaf. A tree house out back in an enormous oak with an elevator and indoor plumbing. A Gothic fan-vaulted nave with stained glass windows, a chapter house with pool tables, and a 5-lane bowling alley in the undercroft. A library with two-story bookshelves and rolling library ladders. A stone wine cellar reached from the secret bookcase door in the library. A big red barn with moo-cows and milkmaids wearing really cute milkmaid outfits. A missile silo filled with lager. An extreme topiary filled with dinosaur-shaped hedges the size of actual dinosaurs. A bell tower with a carillon that’s MIDI-controlled. An observatory dome with a 30-meter reflector. Minarets.
Also, a whole house fan. I miss the one from our old place, it was pretty neat.
