This property, initially developed by the esteemed William Willett, holds significant potential for creating an outstanding family home in the highly desirable NW3 area. With full planning permission already granted, there is a unique opportunity to undertake an ambitious extension and reconfiguration project, transforming this residence into approximately 8,500 sq ft of living space spread over four floors. The approved plans will not only enhance the property's dimensions but also maintain the architectural integrity of its original Arts & Crafts style. Once developed, the home will feature expansive reception areas suitable for both formal gatherings and casual family use, complemented by six to seven well-appointed bedrooms. Additionally, a dedicated leisure level will incorporate luxurious amenities such as a swimming pool, gym, and media room—ideal for modern living in Prime Central London. The vast rear garden stands out as one of the largest on Elsworthy Road, offering privacy and a generous outdoor space that is rare in this bustling neighborhood. Fronting onto an elegant residential avenue allows for secure off-street parking for multiple vehicles. Located conveniently near the green expanses of Primrose Hill and within reach of local cafes and essential services in St John's Wood and Belsize Park, this property represents a remarkable investment opportunity to create a bespoke family residence that harmonizes heritage with contemporary convenience.
