The latest addition to the Mason & Fifth collection continues the tradition of selecting London's most sought after neighbourhoods, offering beautifully designed private studios alongside thoughtfully curated communal spaces. 

Each stay blends comfort, lifestyle and community, bringing together like-minded guests and cultivating a growing following for this flexible, modern way of living.

There are spaces for guests to gather, in the airy double-height guest lounge with slouchy sofas, comfy seats and two feature chimneys crafted to enhance the space and create the perfect atmosphere for relaxation, the restored chimney breast boasts modern design features, along with bespoke tables and chairs to work 'from home' from.           

There's a communal open kitchen for guests to use as their own - and each morning there's a help-yourself breakfast bar with fresh fruit, granola and yoghurt, freshly baked bread, fresh juices and coffee for guests to enjoy.

Every weekend begins with, 'Wine Down Fridays', where guests are invited to enjoy a glass of wine from the local bottle shop, hosted by the House Team, a chance to unwind and connect.

For the most elevated experience, the two Best in House studios are housed on the top floor, with vaulted ceilings and sofabeds making them suitable for families, with one also having a bath in addition to a shower. Every studio comes fully furnished with luxury mattresses, smart TVs, superfast Wi-Fi, organic bathroom products and regular housekeeping.

The interiors at Mason & Fifth, Belsize Park embrace a philosophy of low impact and sustainable living, with quiet richness, carefully honouring the heritage of the restored estate. A sensitive and stripped back approach reveals the building's original textures, celebrating repair over replacement. Throughout the studios, generous volumes and abundant natural light are complemented by timber floors, soft linens and timber furniture, creating a number of spaces that feel calm and grounded.

Kitchenettes feature live edge limestone worktops crafted from rejected stone, wardrobes are conceived as demountable systems inspired by mid-century design. In the communal areas, a striking double-height timber extension forms the heart of the building, bringing together the kitchen, dining and workplaces beneath sculptural chimney breasts in hand glazed tiles.  Throughout, collaborations with British markers and artists add layers of character and authenticity through craftsmanship, resulting in warm tactile and thoughtful interiors, a refined yet relaxed backdrop for modern, flexible living in Belsize Park. 

To celebrate the launch, Mason & Fifth, Belsize Park announces a “Writer's Residency”, in collaboration with Port Magazine. An initiative celebrating local wordsmiths, authors, poets and journalists, the residency offers four selected writers a chance to explore their craft and work with leading industry professionals across varying written disciplines. Recipients will be granted two months accommodation in a Mason & Fifth, Belsize Park studio, their work published in Port Magazine, and access to mentorship. The residency will open with a shared dinner, bringing the writers together with the Port and Mason & Fifth teams, and conclude with a public event in the building, curated by the Port team, showcasing the work created during the programme. More details to be revealed shortly.

Before the doors officially open on Monday April 13th, Mason & Fifth are hosting a special pre-opening 'soft launch' week at Mason & Fifth, Belsize Park between Monday 11th May and Wednesday 13th May (inclusive), with limited studios available to book for just £50 per night, including breakfast.

Mason & Fifth Founder Ben Prevezer says - "Mason & Fifth, Belsize Park marks an exciting new chapter for us in one of our favourite areas in London. Each building we open is thoughtfully shaped by its neighbourhood, and we hope to be a welcome addition to this special London community''.

With excellent transport connecting the building to Central London and a stone's throw away from Hampstead Heath and Primrose Hill, this makes Belsize Park, a hidden green gem in the city's heart.

Room rates start at £180 per night.
