It is hard to imagine a home as regal and unique as the Mansion House. Originally designed by Horace Field, its untold heritage and prestige are evident throughout. Meticulously renovated, this historic property will make a truly exceptional family home. The house is over 15m wide and has an array of illustrious period features such as the sweeping central staircase, the spacious oak-panelled drawing room, and the ornate gilt cupola. In addition to the intricate marble detailing and Royal Palace craftsmanship, the house also comes with a stunning private roof terrace that offers expansive views across Big Ben, the House of Lords, and Westminster Abbey. Its bespoke leisure amenities include a spa with its own gym, sauna, steam room, jacuzzi, patio garden, and 10m swimming pool. There is also an 8-person lift, a walk-in wine room, a games room, a cinema, a bar, and a double kitchen with Miele and Gaggenau appliances. The house also has an integrated audio-visual and lighting system and comfort cooling. All seven bedrooms are en-suite and generously proportioned. The principal suite also comes with a walk-in dressing room, a private terrace, and two en-suite bathrooms. Mansion House was reinstated as a private residence in 2017. It has undergone an extensive refurbishing process to honour its history and also integrate the latest amenities, creating the ideal haven for luxury living. It is located on Cowley Street in Westminster. Set in the heart of central London, it is surrounded by some of the country’s most significant landmarks, in addition to impressive retail, dining, and hospitality outlets.
