A new 'live escape game' is set to come to Birmingham's Jewellery Quarter later this year.
ClueHQ is planning to open the centre in vacant railway arches in Lionel Street to tap into the city's corporate and group activity market.
The concept will see groups of between two and six people locked in rooms with names such as 'Bunker 38 ' and 'The Vault' and given 60 minutes to solve a series of clues in order to escape.
ClueHQ first launched in Warrington in summer 2014 and now also runs franchises in Blackpool, Sunderland and Brentwood.
The new Birmingham venue will be 3,800 sq ft and housed in Arches 20 and 21, which are owned by Network Rail and were previously the home of gym Arch 20 Fitness which has since rebranded and move to a new home in the Gun Quarter.
It will be able to hold up to 36 guests at any one time and employ up to 12 part-time staff with proposed opening hours from 10am to 11pm.
ClueHQ will pit itself into direct competition with Escape Live, a winner at the 2015 Birmingham Post Business Awards, which operates two separate experiences in nearby Henrietta Street and is also looking to expand within the city.
Documents accompanying Clue HQ's planning application said: "The facility will be the biggest escape room centre for the brand out of any in the country and we hope to help towards increasing the amount of choice for tourism in Birmingham.
"The high corporate market and also general tourism in Birmingham will mean it will be a very successful location."
