The 8,000 sq ft in in the Octagon Chapel in Milsom Place is due to open at the end of summer and will be the group’s third site outside London.
It has recently opened in Cardiff and has also secured a site in the Ship House Canal building in Manchester.
The brand launched its ninth site in London’s Threadneedle Street in the former Orchid Group Pacific Oriental venue in May.
According to sister publication M&C Allegra, the brand is planning to grow its estate away from the capital and is looking to expand internationally with Stockholm set to open.
