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 such as sweeping staircases, gilded cornices, bow windows, and soaring ceilings throughout a series of elegant reception rooms, including a showstopping ballroom that spans the full width of the property. The generous bedroom accommodation offers scope for luxurious ensuite living, while the lower level includes a large kitchen with separate street access and flexible space for a gym, home office, or even an indoor pool (subject to planning). With its rich architectural heritage and prime location directly opposite St James's Park and moments from Buckingham Palace, Westminster Abbey, and the Houses of Parliament, this is an extraordinary opportunity to blend historic grandeur with modern luxury in the heart of London.
