Behind a canopy of mature trees, 61 Belsize Avenue occupies an elevated, sheltered position on one of Belsize Park’s most sought-after avenues. Set back from the road, with off-street parking for two cars, this substantial period home is arranged over five floors and combines generous family accommodation with an exceptional range of entertaining and leisure spaces.

The scale of the house is apparent on entering. A long, bright hallway leads to a sweeping staircase with an ornate iron balustrade and polished timber handrail. High ceilings, decorative cornicing, broad bay windows and a handsome fireplace give the reception rooms their sense of period character.

The four reception rooms are arranged across the lower ground and ground floors, creating a choice of settings for entertaining, family time and quieter moments. The generous kitchen/breakfast room is designed for everyday use as well as larger gatherings. Dark, sleek cabinetry and stone work surfaces are balanced by a substantial timber island, while the broad layout provides ample preparation and storage space.

The house has been comprehensively refurbished, with careful attention to finish throughout. Recognised by the London Borough of Camden, it was nominated for the Camden Building Quality Awards.

The bedroom accommodation is arranged over the upper floors. The principal suite is particularly generous, with a substantial bedroom, bespoke dressing room and ensuite bathroom. Five further double bedrooms each have their own en-suite facilities, offering comfort and privacy for family and guests.

At the top of the house, a spectacular games room with kitchenette creates a dedicated space for recreation and entertaining. A sauna and shower room complete this private leisure floor, giving the house a feature rarely found in a period family home.This versatile space can be considered self-contained, lending itself equally to staff-quarters or grown up children.

The landscaped rear garden offers a calm, leafy setting, with a lawn, established planting and space to sit and dine. A lightwell beside the house brings additional natural light into the lower ground floor, while the garden’s mature greenery provides a sense of seclusion.

With its distinctive tree-screened setting, handsome period architecture, five-floor layout and extensive accommodation, 61 Belsize Avenue offers a compelling balance of family comfort, entertaining space and at-home leisure in the heart of Belsize Park.
