Buckingham Palace's Elusive Layout Has Never Been Made Public — But Researchers May Have Cracked It Anyway

The first thing you see when you enter Buckingham Palace, according to the HomeAdvisor floor plans, is the grand staircase, which is lined with luxurious red carpet and decorated with portraits of the royal family.

Upstairs, you'll find the Music Room (which has hosted several royal christenings, including Prince William's). And across the hallway, there's the iconic Green Drawing Room, where the Queen hosts her weekly meetings with the Prime Minister.

Let's zoom in a bit to one of the most important rooms in the Central Block: The State Dining Room. Notably, Prince William and Kate Middleton’s wedding reception was held here in 2011.

Another important room in this part of the palace is the White Drawing Room, which is used for hosting intimate gatherings.

Next up, we have one of the most important rooms in the palace, the 1844 Room, where the royals receive many of their most distinguished visitors (think presidents and A-list celebrities).

Next door to the 1844 Room is the Regency Room, which is one of the most well-known rooms in the palace, thanks to the Queen's Christmas broadcasts.

The second of the three main sections of Buckingham Palace identified by the HomeAdvisor researchers are the Queen's Apartments. Even though the palace boasts a staggering 775 rooms, the six that make up the Queen's private apartments are definitely the ones in which the monarch spends the most time.

The Queen, like pretty much every member of the British royal family, values her privacy greatly, so very few pictures from this section of the palace have been made public over the years. The only exception to the intense privacy rule in this section Buckingham Palace is the Audience Room, where the Queen meets weekly with Prime Minister and for private meetings with the Chancellor of the Exchequer before a new budget is announced. The Queen has also been known to hold audiences here with visiting heads of state who aren't on an official state visit.

Finally, there's the East Front, which is set to undergo a major, £369 million makeover this year. This part of the palace contains the iconic Yellow Drawing Room, where the queen recorded her Christmas broadcast in 2004. There's also a gorgeous space called the Centre Room, which was formerly known as the Chinese Dining Room and is furnished in the Chinese regency style.
