This Grade II listed apartment in Westminster offers a rare chance to create a bespoke home of remarkable scale and character. Behind its private porticoed entrance lies a grand residence featuring a private lift, magnificent ballroom, sauna, and sole use of a beautifully landscaped garden with direct access to St James's Park. The property boasts original period features, including sweeping staircases, gilded cornices, bow windows, and soaring ceilings throughout a series of elegant reception rooms. The showstopping ballroom spans the full width of the property and promises to become one of London's most impressive private entertaining spaces. With generous bedroom accommodation offering scope for luxurious ensuite living and flexible space for a gym, home office, or even an indoor pool (subject to planning), this extraordinary opportunity combines historic grandeur with modern luxury in the heart of London, directly opposite St James's Park and moments from Buckingham Palace, Westminster Abbey, and the Houses of Parliament.
