What MASON & FIFTH LIMITED does

Mason & Fifth is a London-based boutique hospitality operator founded in March 2020 by Ben Prevezer, operating a portfolio of serviced guesthouses with flexible nightly-to-monthly stays in prime residential neighborhoods. The active estate comprises Westbourne Park (332 studios), Primrose Hill (60 studios), and Belsize Park (56 studios) — approximately 448 studios in total — with a previously operated Bermondsey location now closed. Its core accommodation product is fully furnished en-suite studios with kitchens, smart TVs, superfast WiFi, and all-inclusive monthly pricing ranging from £130/night (Out & About tier) up to £3,895/month (Best in House at Westbourne Park).

The underlying technology is a guest-facing mobile application integrated with The Dots platform (joint data controller for authentication, analytics, and digital key-card building access), supplemented by Acuity Scheduling for wellness bookings and integrated event RSVP/booking management. Distribution combines direct website booking and the mobile app with third-party booking platforms (Booking.com, Airbnb) and on-site enquiry teams. Operational technology is asset-heavy and consumer-facing rather than software-defined.

Revenue mechanics span five streams: (1) serviced accommodation (primary, transaction and recurring monthly subscription), (2) The Grounding wellness services including Reformer Pilates (£15), general classes (£20), 1-2-1 PT (£90) and small-group PT (£35), (3) Meadow creative workspace memberships (Workbench £25–£250, Workshops from £2,085/month), (4) Canal restaurant F&B with corkage fees (£50–£75/750ml), and (5) third-party booking platform commissions. The company serves a mix of individual travelers: digital nomads and remote workers, artists and creative professionals (the primary segments), as well as business travelers and leisure guests. Marketing is Instagram-led, supported by the Spirit Level editorial platform, weekly events programming, and the Mason & Fifth x Dazed Club artist residency (800+ applicants for 8 positions in the first cohort).
