By the late 19th century, the Ottoman Empire was limping towards oblivion. A fragmented agglomeration of countries, ethnicities and languages, the empire was under-funded and crumbling from within.

Its third-to-last, increasingly repressive sultan, Abdul Hamid II, was forced to abdicate in 1909.

Shortly before that, one of his ministers, Müşir Zeki Pasa, began work on a massive, 26,900-square-foot (2,500 square-metre) Istanbul mansion, in Turkey, on the bank of the Bosphorus – the strait separating Europe from the Anatolian peninsula of western Asia.

Designed by the French architect Alexandre Vallaury, the five-storey building had manicured gardens, a ground-floor hammam, or Turkish bath, grand windows overlooking the strait, and lavish ornamentation.

When the sultan fell, most of his ministers did, too, and Zeki Pasa went into exile. 

The mansion – a palace, really – was transferred to the royal family and deeded to the last Ottoman sultan’s youngest daughter, Sahiba Sultan, and her husband (who was also her cousin), Ömer Faruk.

After the sultanate was abolished in 1922, the princess and her family fled to southern France. 

The house, after sitting empty for a few years, was bought by the Bastimar family, whose wealth was derived from tobacco.

For the next 85 years, four successive generations of Bastimars lived in the house. 

Now, faced with maintaining a home that requires three servants for every floor (and that does not include gardeners and chauffeurs), the matriarch of the family has put the mansion up for sale.

It is listed for U$95 million with Ayikcan Real Estate, a member of Leading Real Estate Companies of the World.

Tobacco storage

“When the Bastimars first bought the house, they actually used it as a tobacco-storage facility,” says Pinar Ayikcan, the broker who represents the listing. 

“They lived in a palace nearby.”

When the structure was built, it was situated in a wealthy, low-slung neighbourhood dominated by gracious, single-family villas and elegant gardens.

Over time, most those mansions were demolished. Even though the neighbourhood is still affluent, the house is one of the few remaining villas of its size.

“It’s one of the biggest estates in Istanbul,” Ayikcan says. “And it’s the largest residential house on the Bosphorus, at this point.”

The house is occupied by the family matriarch, who was four years old when her family moved in, plus her daughter-in-law and granddaughter. 

The women live on separate floors with separate staff. 

The house has 23 bedrooms, four living rooms and eight bathrooms.

Most of the interiors are original, as is much of the furniture, Ayikcan says. 

“There are chairs that were owned by Louis XIV, along with furnishings, including Murano chandeliers, that date back to the Ottomans. 

“Everything has been kept up,” she says. 

“The windows, the marble – the ceilings, even. It’s all original.”

The house has other esoteric features. There is a sink in a large meeting room on the first floor.

“During high-level conferences, they would turn on the sink, and the noise of the water would drown out their conversation, in case of eavesdroppers,” Ayikcan says. 

A lofty price

The house has 360 feet (110 metres) fronting the Bosphorus, as well as a footprint of slightly less than an acre (about half a hectare).

As rare as the property is, though, it faces a few hurdles to selling at the listed price. 

First, it’s dwarfed by the massive Fatih Sultan Mehmet suspension bridge, which is almost directly above the property. 

No matter how lovely the view, the presence of an eight-lane highway suspended 210 feet above your garden might put a pall on sunbathing.

Second, there’s, well, the price. At US$95 million, it’s out of reach for many domestic buyers, and the political situation in Turkey might give an international buyer pause.

For that amount, after all, there are myriad options in every major financial centre around the world. Someone interested in safeguarding money through residential investment might prefer a more stable government.

“A local person could buy it for business purposes, to perhaps, make a unique hotel,” Ayikcan says. “Or it could be a consulate or – of course, if someone wanted a very, very special residence – they could buy it for that, too.”

The mansion has been on the market for about five years, but Ayikcan says the sellers are not in a rush. 

“They don’t want to sell it for nothing,” she says. “It’s a palace, not a regular home.”
