The White House and Buckingham Palace - can one compare? Hardly, other than both are residences which contain offices. The White House has 132 rooms including 16 family-guest rooms, and 35 bathrooms. The Palace has 775 rooms, with 52 Royal and guest bedrooms, and 78 bathrooms. Another difference-- originally Buckingham Palace was privately owned. An 18th century politician, John Sheffield, Duke of Cambridge, built in 1703 what was then called Buckingham House.
