Northwest Manor

Northwest Manor, also referred to as the Northwest mansion, is the home of the Northwest family, Pacifica Northwest, Preston Northwest, and Mrs. Northwest.

History
In "The Golf War," the Pines family and Soos drove Pacifica home as a nice gesture by Mabel since her parents hadn't arrived to pick her up. After Pacifica opened the gates to her home, Dipper and Mabel saw how exquisite it was and agreed they should have charged her for the taco Mabel gave her.

Outside
The front yard of the Northwest Manor has water fountains, peacocks, and a statue that resembles Pacifica behind a large metal gate. Two patches of hedges are cut to spell the letters "N" and "W". The house itself is two stories tall and appears to be gigantic on the outside. The manor resides on the top of a mountain.

Inside
The manor is filled with various decorations and appliances made from animals. This includes a wall of taxidermy animals, and a chandelier made of antlers.
