Full Venue Hire at 3 Hanover Square

Full venue hire at 3 Hanover Square brings both gallery floors together into a single 6,500-square-foot event space with a combined capacity of 420 standing. The ground-floor Main Gallery and basement Lower Gallery operate through a transparent glass platform floor — a connection that is as much architectural feature as structural element, with light passing between levels and guests able to see across floors. Unit London’s rotating exhibition programme provides the backdrop, which means the visual environment changes with each show — an advantage for clients hosting repeat events or annual gatherings.

Two Galleries, Two Characters at 3 Hanover Square

The Main Gallery on the ground floor is the larger space: high vaulted ceilings, natural daylight through full-length glass frontage, mirror-finished black concrete floor, and the current exhibition as backdrop. The Lower Gallery below is more contained and intimate — white walls with reclaimed parquet flooring, the glass ceiling connecting it visually to the space above. Each floor has its own fully equipped kitchen and back-of-house area with rear loading bay access, meaning both can support independent catering operations simultaneously. That two-floor structure creates natural event zoning. Drinks receptions or exhibition elements on the ground floor, with seated dinners or presentations in the Lower Gallery. Or reverse it — use the intimate basement for VIP hosting while the main gallery handles the wider event. The spaces can operate independently or together, which is what makes full venue hire flexible rather than just large.

Full Venue Events at 3 Hanover Square

At 420 standing, full hire suits large-scale product launches, brand activations, exhibitions, networking receptions, and celebration events that benefit from multiple zones. The shared production infrastructure — six-metre LED screen, 32-speaker audio system, track lighting, and rigging points across both floors — supports ambitious production without requiring external technical build. Fashion shows, immersive experiences, and screenings all use the two-level architecture to create environments that single-floor venues can’t replicate. Dry hire with an approved caterer list gives clients control over the food and drink proposition. Two onsite kitchens with rear loading bay access ensure catering logistics run smoothly at scale. Six unisex toilets, air conditioning, and full disabled access are standard throughout.

3 Hanover Square: Location and Positioning

The Mayfair location on Hanover Square positions full venue hire for high-profile corporate events, luxury brand activations, charity galas, and awards ceremonies where the address and the gallery association reinforce the occasion. The W1S postcode carries weight for client entertaining and press events where setting communicates as much as content. Oxford Circus station — Victoria, Bakerloo, and Central lines — is three to five minutes on foot, and Oxford Street bus routes provide additional access from across London. The licence runs to 1am with extensions available.
