A £44 million Chelsea Barracks penthouse featuring its own ice-bath and sauna has gone on the market in one of London’s newest exclusive addresses.

The five-bedroom Penthouse at 9 Mulberry Square, designed by renowned interior designer Susie Atkinson, has panoramic views of Chelsea Barracks, Belgravia, and the London skyline that can be admired from the 333 sq m terrace that encircles the residence.

The area has jumped in popularity in recent years. The owner of the Penthouse at 9 Mulberry Square will count Tom Ford as one of their neighbours after the US billionaire designer reportedly bought a £80 million house in the area just before the stamp duty rise deadline following Rachel Reeves’s budget.

Luxury wellness in the sky

An onsite-gym in a prime property is no longer enough for many UHNWs.

A recent report by the Global Wellness Institute revealed the global wellness industry was worth $6.3 trillion in 2023 – nearly 14% higher than its size in 2019. The global real estate sector is capitalising on the trend, with health-enthusiast buyers increasing seeking properties that champion wellbeing and healthy lifestyle.

This outdoor space at the Penthouse at 9 Mulberry Square is divided into zones: there is a wellness area with hot and cold therapy facilities, a tranquil herb garden, and multiple areas for relaxation. There is also an outdoor bar, fire pit, BBQ, and a formal dining area. The landscaped terrace, by Hortus Loci, incorporates native grasses and evergreens, creating a peaceful retreat.
