Description

This unbroken freehold building consists of six residential units spread across lower ground, ground, and three upper floors, totaling 2,362 sqft (NSA) in the sought-after area of Marylebone. It features four one-bedroom apartments and two studio flats, with the lower ground unit having access to a private terrace/garden—a rare find in this desirable locale. The potential for modernization is significant; Flat C is in need of complete refurbishment, while the other units provide opportunities for lighter touch-ups to maximize their appeal and rental yield. Currently, four units are vacant, creating a unique investment opportunity for immediate income generation upon renovation. Additionally, the property’s neighbors have successfully added extra storeys and expanded spaces such as garden vaults and terrace areas (subject to planning permission), which could further increase overall value. Centrally located near Marylebone High Street's eclectic mix of shops and eateries, along with Baker Street and Marylebone stations nearby providing excellent transport links across London, this property presents an exciting opportunity for redevelopment in a vibrant community.
