Union House Southwark
Situated in Southwark on the intersection of Great Suffolk Street and Union Street, the iconic red brick Union House, historically a warehouse converted into offices, has undergone a substantial redevelopment.










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.

Sustainability is incredibly important for the Client and as such the building is targeting BREEAM ‘Outstanding’, WELL ‘enabled’ Gold, alongside WiredScore Platinum. In addition, the Design for Performance approach is being adopted in order to minimise operational energy and hence carbon emissions.

The completed site now comprises four detached industrial warehouse units ranging from 14,000sq ft to 36,000sq ft, all with naturally ventilated and heated offices. The two larger units each have an 8 person MRL passenger lift, while the smaller units have been provided with platform lifts. The warehouse area was designed as a shell for future fit-out with capped off utility services.

Located in the heart of London’s West End, 9 Cavendish Square is undergoing a high-quality refurbishment to transform this prestigious address into a modern, efficient, and sustainable workplace. The works involve a full mechanical, electrical, and public health (MEPH) services upgrade to deliver a building that meets contemporary operational and environmental standards.
