Multistory is the bringing together of two separate buildings (formerly 2 Colmore Square and Cannon House) to create one exceptional workspace featuring Birmingham’s largest amenity space that ties together communal areas for inhabitation on a work and social basis.
The key improvements that have been made as part of this project include, 2 new receptions for a best-in-class arrival experience, the introduction of a 100-person Auditorium, new lifts with destination control, a bar/coffee lounge, an outdoor terrace, communal bookable meeting rooms, generous co-working areas, new car EV charging points, best in class cycle storage and outstanding showers and changing facilities. Multistory is setting the new benchwork for Sustainability, achieving WiredScore Platinum, Fitwel 2 star and Energy Performance Certificate (EPC) of ‘B’.
Air soured heat pumps provide the heating and cooling to the amenity areas with heat recovery air handling unit providing fresh air. White box retail units are provided at ground floor level with larger retail units within the lower ground level. The two levels are linked with a grand staircase.
