The serene Bamford Haybarn boutique, fitness studio and spa on Brompton Cross in South Kensington is the kind of place that leaves you longing to dress only in grey cashmere and crisp white cotton. Designed by Crawford & Grey architects and spread over three floors, the bright and airy space draws on the natural surroundings of the countryside – all whitewashed walls and luxe timber fixtures, with lots of natural light.

The ground floor is curated with Bamford’s namesake collections of clothing, skincare and interiors, with a sociable herbal tea infusions bar at its centre, serving steaming glass cups of calming goodness. Upstairs leads to London’s most beautiful skylit yoga and pilates studio, with a real tree bark sculpture artfully climbing one wall. Weight-pumping workouts are eschewed in favour of strengthening yoga, pilates and meditation and there is an ever-changing programme of practitioners, talks and wellness workshops.

A cocooning Bamford Spa is nestled in the basement, completing this trifecta of wellness. On the menu are facials, myriad kinds of massages, osteopathy, acupuncture, reflexology and reiki.

Lady Carole Bamford opened the first Bamford Haybarn Spa at Daylesford Farm in the Cotswolds in 2002. There are now six outposts worldwide, including Brooklyn, Tokyo and The Berkeley hotel in Knightsbridge. Bamford’s unique brand of wellness has long supported mindfulness, zero waste and thoughtful, slow consumption. Knitwear is spun from Scottish cashmere, combining the latest in sustainable yarn development with age-old tradition, while yoga pants are crafted from hand-woven cotton cloth, all in a signature palette of neutral tones.

The organic beauty line is concocted using nontoxic botanical oils and pure ingredients, housed in lovely green glass bottles and curated alongside salt rock candle holders, cushions and ceramics.

The yummy-mummy Bamford haven has always managed to avoid the scepticism associated with other luxury wellness brands because it champions authenticity from the ground up, supporting keep-forever purchases and independent British makers. There are no kooky gimmicks at Bamford – simply well-made, nurturing and nourishing products, instilled with an unrivalled sense of calm.
