Occupying an elegant position along one of Belsize Park’s most established residential avenues, this handsome Edwardian family home extends to approximately 3,659 sq ft across four beautifully proportioned floors, combining exceptional period character with contemporary family spaces.

A distinguished red-brick façade, decorative stained-glass windows, generous ceiling heights, and beautifully preserved original detailing establish an immediate sense of grandeur and charm. The ground floor has been thoughtfully reimagined for modern family life, centred around a magnificent reception room with ceilings exceeding 10 ft, which flows seamlessly into an impressive kitchen and dining room. Together, these spaces create a wonderful lateral heart to the home and open directly onto a tranquil landscaped garden, perfectly suited to entertaining and indoor-outdoor living.

Accommodation is arranged across five generously proportioned bedrooms and multiple bath and shower rooms. The principal suite occupies the first floor, complete with a generous bathroom and a light-filled conservatory dressing room. Above, the upper floor provides three further bedrooms and additional bathrooms, where vaulted ceilings and skylights create bright, characterful spaces.

The versatile lower ground floor currently comprises a cinema room, gym, study, guest accommodation, and extensive storage, providing exceptional flexibility for evolving family needs. Blending the craftsmanship and proportions of its Edwardian origins with the comforts of modern family life, the house offers a rare balance of elegance, practicality, and enduring appeal in the heart of Belsize Park.
