Whilst “Architect Member” is restricted to registered architects, associate membership has been available for many years to others within the local architectural and design community, including interior designers, architectural technologists/technicians and draughts persons. Currently the IBA represents approximately 57 architects and 125 allied designers and support staff.

In addition to promoting the local profession, the IBA is the collective voice for architects in matters relating to local Government Departments, the introduction of standardized construction contracts in Bermuda and for securing collective pension, health, professional indemnity and workmen's compensation policies for its members.

The IBA actively encourages Bermudian students who wish to enter the architectural profession, and has long offered a scholarship for aspiring architectural students - recently renamed the Stanley G Kennedy Scholarship - and administers a second scholarship for local architectural students on behalf of the Lepercq Foundation.
