The residence at 24 Sussex Drive is a large, limestone structure set on on the south bank of the Ottawa River, next to the French embassy and opposite the main entrance to Rideau Hall. The house consists of 35 rooms spread on four floors, including the basement, connected by an elevator and many staircases. The latter consists of support rooms, while the main floor holds the dining room, living room, kitchen (which is staffed by a head chef and support staff), main stair hall, prime minister's library, and a sun room. The second floor is primarily bedrooms, including the master bedroom, as well as a family room (described by Margaret Trudeau as her "freedom room") and the office of prime minister's spouse. The third floor contains additional bedrooms and a private study for the prime minister.
