The open event is taking place between 2-7pm this Monday, November 4, at the town library in Stratford Road.
The moving of the library into the former Parkside Middle School building, in Stourbridge Road, is part of a larger scheme to create a one-stop shop of council services at the site.
The scheme includes a new Civic Centre for Bromsgrove District Council, office accommodation for Worcestershire County Council staff based in the town and the relocation of the Registration Service and Bromsgrove Customer Service Centre.
Those attending will have the chance to view designs for the inside of the new library, as well as the external images.
Residents will also have the chance to take a look at the architects briefs and council officers will be on hand to explain the designs and answer questions.
Councillor Lucy Hodgson, Worcestershire County Council's cabinet member for localism and communities, said: "We are very excited at the architects designs for the new Bromsgrove Library and wider Parkside development.
“I encourage as many local people as possible to come along to the event on Monday, November 4, to take a look at the designs for the library and take the opportunity to ask any questions they may have.
"The overall plans for the former school site are ambitious and will enable us to locate a number of services and organisations in a single building, increasing access and convenience for residents and delivering savings for partners."
