Description

This Grade II listed building, originally built in the 18th century, presents a unique opportunity for renovation and investment. Spanning an impressive 4,268 sq ft (396.4 sq m), the property is currently configured with office space across the lower ground, ground, and two upper floors, alongside residential accommodation on the third floor. It features high ceilings and abundant natural light, enhancing the spacious feel of the interiors. The building is located in a highly sought-after area of Mayfair, surrounded by luxury amenities and prestigious retail outlets. The potential for conversion into a single-family residence offers exciting possibilities for an investor or a homeowner looking to personalize their living space. Proposed enhancements include constructing a new basement, exploring the option to excavate beneath pavement vaults, installing modern plant and solar panels on the main roof, updating windows on both front and rear elevations, and incorporating two internal lifts with only minor internal alterations required. Previously granted planning permission for these developments has lapsed but can be re-applied for, paving the way for significant value addition through thoughtful renovation.
