Plot, Courtenay Avenue, N6 (SOLD)

Property Summary

Set on one of London’s most exclusive private roads, this six-bedroom detached residence on Courtenay Avenue presents an exceptional opportunity to create a landmark home. The existing house extends to almost 10,000 sq ft, occupying a rare double-width plot of approximately one acre—one of the largest in N6. Behind the existing façade, full planning consent (granted via appeal) allows for the redevelopment of a new super mansion of around 19,000 sq ft, offering vast potential for an incoming owner to realise a world-class residence in this coveted Highgate enclave. With 24-hour security at the top of the road, tennis courts, and landscaped gardens, this is a property of immense rarity and promise.

Design Comment

Planning permission (secured via appeal) provides for the creation of a spectacular new home of approximately 19,000 sq ft behind the existing façade. This allows for the integration of luxury amenities such as a subterranean leisure complex, spa, cinema, pool, and staff quarters—transforming the site into one of North London’s premier private residences. The double-width nature of the plot allows for exceptional landscaping potential, outdoor entertaining spaces, and architectural grandeur within a discreet and secure environment.
