Portland House

What Portland House does

Portland House operates a multi-functional events venue and office space business from a Grade II listed 1926 former NatWest Bank building at 113–116 Bute Street in Cardiff Bay, Wales. The company's core offering is the 4,000 square foot historic banking hall — featuring original marble pillars, an arched glass ceiling, and Doric Frieze design — which is hired out for weddings (up to 320 seated, 700 standing), corporate events, live music, theatre productions, and Christmas parties, with bespoke in-house catering, drinks packages, and full event planning support. A secondary recurring revenue stream is flexible office space rental on 3-month rolling contracts, complemented by conference room hire, concierge service (09:00–17:00), 24/7 fob access, and direct Cardiff Internet Exchange connectivity.

The business also monetizes the building's distinctive architecture as a filming location, with a documented client roster including the BBC (Doctor Who, Torchwood, Casualty), Warner Bros Pictures, Channel 4, S4C, and Twenty Twenty. The Vaults sub-brand extends event capacity into an adjacent venue operated with Vaults Presents. Distribution is entirely direct-to-consumer and direct-to-business via the company website, phone, on-site viewings, and a virtual tour, supplemented by email newsletters and a social presence on Facebook and Instagram.

The company is privately held, headquartered in Cardiff, with a headcount band of 11–50 employees. No parent company, institutional investors, funding rounds, or acquisitions are disclosed in the available material. Pricing for events is quote-based and per-head (e.g., catering from £25/person, ceremony from £245+), while office space is subscription-based (e.g., featured office at £550/month with optional 100mbps upgrade for £30). No revenue, ARR, or GMV figures are publicly disclosed.
