Turkey ’s new president has been accused of behaving like a “sultan” after he installed himself in the biggest residential palace in the world, built for a price tag of £384 million.

Recep Tayyip Erdogan now resides in the White Palace, which was constructed in breach of court orders in protected forest land in the capital, Ankara.

Boasting 1,000 rooms covering a total floor area of 3.1 million square feet, the palace is four times the size of Versailles, allowing Mr Erdogan to exceed the residential grandeur of Louis XIV, the “Sun King” of France.

Inside the palace, a majestic hallway leads up to a sweeping staircase. The quixotic architectural style seems to cross the Ottoman and Seljuk traditions with that of a modern Chinese railway station.

The bathrooms have silk wallpaper and the whole edifice is surrounded by a forested park. Hundreds of trees were felled to make way for the president’s new home.

Mr Erdogan, who designed much of the White Palace himself, has also taken the precaution of installing an underground bunker.

Mehmet Simsek, the Turkish finance minister, said the total cost of the complex amounted to £384 million – twice the earlier estimate.

Critics of Mr Erdogan, who won the presidency in August, denounced the project as a folie de grandeur. “The so-called sultan has built this for himself in a country where three million people are without work,” said Kemal Kilicdaroglu, the leader of the opposition Republican People’s party.

“You cut down hundreds of trees to build yourself this palace.”

Mr Erdogan served as prime minister for 11 years before ascending to the presidency. Although his AK party does not hold the two thirds majority in parliament required to amend the constitution, his ambition is to turn this traditionally ceremonial post into the new centre of power in Turkey.

Unlike all previous presidents, Mr Erdogan routinely chairs cabinet meetings. He has also spent £115 million on a new presidential jet, designed and supplied by Airbus to his own specification.

As for critics of his new palace, Mr Erdogan said: “No one can prevent the completion of this building. If they are powerful enough, let them come and demolish it.”
