Paradise’s Three Chamberlain Square in Birmingham has been awarded the Commercial Development of the Year for the West Midlands at CoStar’s Impact Awards 2026. The 189,000 ft2 building was judged by an independent panel of real estate professionals and has been fully let at the start of 2026 by CBRE, EY, Eversheds Sutherland and Forvis Mazars.

Cundall provided multi-disciplinary services for this project including building services, structural engineering, sustainability, lighting design, and acoustics. The development is the first in the West Midlands to receive a 5* NABERS UK Design Reviewed Target Rating with our multi-disciplinary team leading the development of design solutions to achieve significantly low operational and embodied carbon. The original brief set a target for upfront embodied carbon not to exceed 600 kgCO₂e/m², aligning with LETI Band C for offices. Through a combination of significant design and construction decisions, the upfront embodied carbon was reduced to just 449 kgCO₂e/m², achieving compliance with LETI Band B for offices, exceeding the initial ambition.  

Joe Williams, Director, Land and Development at Avison Young, and one of the judges commented: "The latest office development within Paradise serves as another key advertisement of the city. Its appearance and energy credentials are best in class and will serve to attract further investment into the city centre at a time when it is most needed."

Mike Gosling, Partner and project lead from Three Chamberlain Square, commented:  

“Three Chamberlain Square was a project that we started before the pandemic, and the project has truly set the standard for what a modern office space should look like. Working with a forward thinking client like MEPC with a genuine passion for sustainability is what made this project a reality.”  

Congratulations to the project team, MEPC, FCBStudios, Sir Robert McAlpine, and AtkinsRealis, on this great achievement!
