Events at JW Marriott Grosvenor House London
Grosvenor House has two distinct settings in our portfolio: the Great Room for awards and company celebrations, and the Ballroom for a wedding reception. The room name matters when planning a production brief; their scale and layouts are different.

Kudos AV projects
Awards, galas and company celebrations
The Asian Awards and Dental Beauty Partners Awards show different screen and stage designs. The Dental Beauty project also brings a printed dancefloor and party lighting into the Great Room programme.
Kudos AV projects
Ballroom weddings and receptions
The wedding uses a curved LED screen, an Italian-inspired white stage, bespoke tables and walkways, lighting and foyer print to carry one design throughout the guest journey.
Plan the production around your event
For a Great Room awards dinner, develop the main screen picture, camera relay and sound coverage with the full table plan. In the Ballroom, a wedding design may need a stage, dancefloor, bespoke tables, a bar and printed arrival details. Allow those features their own footprint rather than treating the venue’s maximum dining capacity as the finished production layout.
