Earlier this year, the Raffles London hotel opened in the Old War Office. After a £1.4 billion ($1.76 billion) renovation, some of the suites—including Winston Churchill’s old office—are available for £25,000 a night.
The renovation took seven years and the five-star luxury hotel officially reopened on September 29. It now has 120 rooms and suites, 85 private residences, and nine restaurants. The penthouse in the residential area of the hotel could go for £100 million.

There’s limited space to build in London these days, which is why developers are setting their sights on these historic buildings. Even when more challenges and higher costs come with working with landmarked properties.
“American clients have been loving the history and charm of some of these older buildings,” property agent Will Watson told Bloomberg.

In Chelsea, the Lots Road Power Station which once powered the London Underground is also under development. It will soon become a residential address next year. The cost of the flats range from £1.7 million to £15 million.
According to the Powerhouse Chelsea Waterfront website, the property will include a 20-meter swimming pool, jacuzzi, sauna, riverfront restaurant, state-of-the-art fitness center, and wellness facilities.
Meanwhile, on the edges of Westminster, the Whiteley was once one of London’s first department stores. It’s currently being converted into luxury apartments that start at £1.5 million.

The Whiteley will also be home to Six Senses Place, which is “a new kind of social club where wellness, community, and celebration meet,” according to its website. The brand believes in holistic treatments and champions sustainable practices as well.
Alex Michelin, founding partner of the developer Finchatton, told Bloomberg, “You can buy a glass tower anywhere. But when you move into the Whiteley, it’s clear you’re in a historic building in London.”
