Auditorium & Exhibition Space at 30 Euston Square

The Auditorium at 30 Euston Square seats 300 in fixed tiered rows — a genuine lecture-theatre configuration designed for presentations, not a flat function room with chairs arranged hopefully. The sight lines work from every seat, the rake ensures clear views of the stage, and the technical specification matches the architecture’s ambition. What makes this a specialist conference facility rather than just a large room is the AV infrastructure. A Sony HDR 4K laser projector — DCI cinema-approved, the same standard used for commercial film screenings — drives the main display. Immersive surround sound fills the auditorium without the dead spots that plague converted ballrooms. Dynamic show lighting, integrated video conferencing and live streaming capability mean hybrid events run from the same control setup as in-person ones, with dedicated AV technicians on hand rather than a phone number for an external supplier.

30 Euston Square’s Exhibition Space and Atrium

Directly adjoining the auditorium is a 360 sqm Exhibition Space — a bright, airy hall beneath a 24m atrium that rises seven storeys above the floor. The scale transforms what could be a standard foyer into a genuine event space in its own right. A 5m-wide video wall anchors one end, with an 84-inch welcome screen and four large media screens positioned for branding, wayfinding, or presentation overflow. Private registration and cloakroom facilities keep arrival logistics separate from the main auditorium entrance. For conferences, this is where exhibition stands go — the space accommodates around 20 — along with networking, refreshment breaks, and catering service. The atrium’s natural light and height give it a character that underground exhibition halls and windowless foyers struggle to match. Between sessions, delegates move naturally between auditorium and Exhibition Space without navigating corridors or floors.

Breakout Rooms and Syndicate Sessions at 30 Euston Square

Eighteen contemporary meeting rooms on the ground floor provide breakout capacity for groups ranging from two to a hundred. They’re purpose-fitted with AV equipment and Wi-Fi, and their proximity to the auditorium means session transitions don’t eat into programme time. For smaller syndicate discussions or board-level meetings, six heritage boardrooms on the upper floors offer a different setting — period features, natural light, and the kind of environment that signals a change of pace from the main conference programme. The building’s Conference Suite (G4.5) seats up to 100 for standalone events or parallel sessions, functioning independently from the auditorium when programmes split across tracks.

What Works Here — Event Formats and Programme Design

The auditorium’s tiered layout and cinema-grade projection make it a natural fit for AGMs, keynote-heavy conferences, product launches with significant AV content, symposiums, and award ceremonies where stage presence matters. The Exhibition Space doubles as registration hub, networking area, exhibition hall, and catering space — adapting through the day as the programme requires. The combination works particularly well for full-day and multi-day conferences. Morning keynotes in the auditorium, exhibition and networking in the atrium at breaks, syndicate work in the breakout rooms, and evening reception or dinner in the Penthouse State Rooms — the whole programme stays within one building without feeling like it’s trapped there. Private screenings benefit from the DCI-approved projector and surround sound. Corporate presentations that need to land — investor briefings, client showcases, annual results — gain from the auditorium’s purpose-built gravitas.

Catering, Accommodation and Access

Searcys manages all catering in-house — external caterers are not permitted. Day delegate packages cover breakfast, lunch, and refreshment breaks, with seasonal menus drawing on locally sourced ingredients. For evening events, the Penthouse State Rooms (up to 230 guests) and Rooftop Terrace (up to 90) host dinners and receptions that don’t require delegates to leave the building. Forty-one boutique bedrooms on-site, complete with a members’ lounge and gym, turn multi-day conferences into residential programmes without the logistical drag of coordinating nearby hotels. Euston Square station is two minutes on foot. Euston mainline and King’s Cross St Pancras are both within five minutes — national rail, underground, and Eurostar connections all within comfortable walking distance of the front door.
