About The Project:

Colmore Plaza is one of the largest speculative office buildings in the U.K set in the heart of the traditional commercial sector of Birmingham City Centre.

The project incorporated the design and construction of a thirteen storey 320,000 square foot office building complete with category A fit out in order to provide Birmingham with much needed premium office space. The project was awarded the Regional BCO Award for Sustainable Development 2007.

The BCO Awards defines excellence in office space and provides public recognition for top quality design and functionality, as well as acknowledging innovation and focusing external attention on examples of best practice.

The very lastest modeling techniques were used to calculate the impacts and implications of design options, enabling us to take a holistic approach to the design, bringing together the main elements of the building services systems. It was one of the first projects of its size to gain Part L Building Regulations 2006 compliance.

The project utilised the existing 5-storey deep basement to form plantrooms and storage together with a 2 storey car park.
