The Mitre, Hampton Court will be the first hotel from The Signet Collection and is set to open in mid-September.
The hotel will be within a Grade II-listed property that dates back to 1665 and was originally used as ancillary accommodation for guests of King Henry VIII at Hampton Court Palace.
Set on the Thames, the 36-bedroom hotel will include a 60-cover riverside all-day dining and wine bar, a 70-cover brasserie and bar, a 60-cover Orangery, a large riverside terrace, meeting rooms and private dining areas.
The plan is to have around five hotels in The Signet Collection, with the next hotel coming early in 2021.
