Originally completed in 1983, the refurbishment of the grade II listed building, had to be in keeping with the original brutalist design. The building will be extended with an additional floor space at each level with an entirely new top level. However, the majority of the work is changing the inner structure to meet with modern day office requirements.  


The challenge is to take an outdated structure, redevelop it by selective demolition and rebuilding the concrete floor plates and extending the number of floors. The core was not fit for purpose and needed replacement. The old and new reinforcement within the concrete structure had to be connected together, which was challenging, as the reinforcement in the 1980s was twisted, not ribbed, like modern rebar.  


To build extensions to each floor, change the substructure significantly for the new structure supported above. We had to connect the existing concrete to the new structure with varying length dowels to provide a strong bond between old and new.  The core was totally new, with new layouts for modern day requirements. The cores were built within the existing frame using the jumpform method.
