This property, originally crafted by esteemed developer William Willett, offers a unique opportunity to transform an established residence in the highly desirable NW3 area. With full planning permission already secured for an extensive extension and reconfiguration, there is significant potential to create an exceptional family home spanning approximately 8,500 sq ft over four levels. The planned modifications will enhance both the size and functionality of the house while preserving its original Arts & Crafts style. Upon completion, the design will feature spacious formal and casual living areas and accommodate six to seven bedroom suites, catering to modern family and entertaining needs. A noteworthy leisure level will include amenities such as a swimming pool, gymnasium, and media room, aligning with the expectations of contemporary living in Prime Central London. The property's grounds are another highlight; it boasts one of the largest rear gardens on Elsworthy Road, providing an unusual sense of space and privacy in Primrose Hill. Additionally, the property benefits from a secure off-street parking area for several vehicles. Located conveniently between Avenue Road and Primrose Hill Road, residents will have quick access to beautiful open spaces like Primrose Hill and Regent’s Park along with local cafés and restaurants in St John’s Wood, Belsize Park, and Camden. This property represents a rare investment opportunity combining architectural charm with substantial renovation possibilities.
