Store turnover has risen from £8 million in 2012 to £14.1 million in 2015.
Boss David Mordecai estimates that the company can grow from its 30 current stores to around 50 in the next five years.
“The opportunity is potentially much greater, that’s being fairly conservative. But we don’t want to open 20 stores a year because that would make it quite unstable,” Mordecai said.
It will begin its expansion with 10 to 12 Christmas pop-ups, some of which could become permanent. It is looking in and around London for new sites.
