12th Knot at Sea Containers Hotel

Twelve floors above the South Bank, 12th Knot is a rooftop bar wrapped in glass with the Thames, St Paul’s, and the City skyline filling every window. The space sits on top of Sea Containers London — the Tom Dixon-designed hotel between Blackfriars Bridge and Waterloo — and takes up to 300 guests when the outdoor terrace is included. Bright, contemporary interiors draw on the building’s transatlantic travel aesthetic, with an open-plan layout that puts the panoramic views at the centre of everything. The bar operates Tuesday to Saturday, 5pm to midnight or 12:30am, and is available for private hire with a dedicated events team through the hotel.

The Space and Views at Sea Containers’ 12th Knot

The defining feature is elevation. Floor-to-ceiling glass on multiple sides creates uninterrupted sightlines across the river — the City of London, the bridges, and the South Bank stretching out below. Window seats suit smaller groups and champagne service, while the main bar area opens up for standing receptions of 250 to 300 guests. Seated dining configurations accommodate 100 for more intimate formats. An outdoor terrace extends the space with sweeping open-air views. For summer events and sunset receptions, the terrace transforms the evening — the combination of indoor bar and outdoor terrace gives guests room to move between atmospheres without leaving the event. The venue describes itself as genuinely year-round thanks to the covered and heated terrace areas, though the outdoor space obviously comes into its own from late spring through early autumn.

Drinks, Food, and Entertainment at 12th Knot

The champagne list is extensive, positioned alongside seasonal and ingredient-led cocktails — this is a drinks-forward venue where the beverage programme is part of the proposition rather than a standard hotel bar offering. A small plates menu uses seasonal ingredients, providing food options that work for drinks receptions and casual dining without requiring a full sit-down catering setup. Weekend DJ sets covering Afrobeats to house music give the space late-evening energy, and live entertainment features regularly. For private hire, the existing entertainment programme provides a baseline atmosphere, with the option to bring in specific acts or DJs for bespoke events. The hotel’s five-star event support team manages logistics, and the connection to wider Sea Containers facilities — Lyaness cocktail bar on the ground floor, The Gallery for larger receptions, the Screening Room, spa, and 359 hotel rooms — means events can scale across the building.

Events Suited to 12th Knot at Sea Containers

Drinks receptions are the natural format — the rooftop elevation, Thames panorama, and champagne-forward programme create an environment purpose-built for evening entertaining. Corporate client drinks, milestone birthday celebrations, product launches, engagement parties, and Christmas events all benefit from a backdrop that does much of the atmospheric work on its own. The venue particularly suits sunset and evening events where the shifting light across the river becomes part of the experience. As daylight fades and the City lights emerge, the room changes character — a transition that adds drama to any evening format without requiring production. For events that need more than a single space, the connection to Sea Containers’ wider portfolio adds flexibility. A conference in the Amphitheatre on Level 13 followed by drinks at 12th Knot, or a screening in the 56-seat cinema room before a rooftop reception — the building supports multi-format programmes without guests needing to step outside. Blackfriars station is the closest mainline and tube connection, with Waterloo and Southwark tube also within comfortable walking distance. The South Bank location places the venue within London’s cultural quarter — Tate Modern, the National Theatre, and the BFI are all nearby — which adds context for creative industry events and programmes that combine venue hire with cultural content.
