Room Layouts & Capacities

The 5 star J W Marriott Grosvenor House is the oldest hotel on Park Lane, Mayfair and also offers some of the most impressive event space in the Capital. Home to 23 event spaces covering 3,900Sq m, this hotel costs over 400 events per year. The venue definitely has a room for every occasion ranging from the Grand Ballroom hosting up to 2000 guests for dinner to the smaller breakout rooms that can accompany the larger rooms to enhance your day time event.

We love this venue because although this is an extremely large hotel the dedicated events team treat every event the same and you would never feel that there are multiple large events taking place at the same time. We also love that there are two separate entrances to the large ballrooms in order to avoid guests all arriving at the same time to their events.


A short walk from Green Park and Bond Street Stations.
