The London-based venue has seen a substantial increase in evening events having previously associated 60% of its business to daytime conferences.
The grade 1 listed house, located on Carlton House Terrace adjacent to The Mall, has found that its reputation as an events venue has improved with a number of high profile clients, including BP and Rolls-Royce.
Prince Phillip House has increasingly been used as a fine dining event with the introduction of a new head chef, Stuart Cooper.
Becci Thomson, sales and marketing manager, stated: "Repeat business is playing a big part for us in 2014, the Waitrose Christmas showcase will be going ahead again in July and we’re also very excited to be hosting the second installment of Prudential Ride London in August."
November 2013 was the most successful month in the venue’s history.
