Its professionals are located in key cities such as Dublin, London, Manchester, Galway, Cork, Belfast, St Helens, Colchester, Guildford, and Chesterfield.

This acquisition is strategically important for Colliers, enabling it to significantly enhance its service offerings within the built environment.
