The project represents a £3.8 million investment by East Renfrewshire Council.
The new development will see a two-storey extension built on the front of Barrhead Sports Centre, which will offer upgraded sports facilities, a library, a computer suite, learning opportunities, an improved café and wifi access.
Also in the pipeline are a business zone and on-site support and advice on employment and getting back to work.
Meeting rooms for conferences, training events and other activities will be available for community groups and local businesses to book.
Vice-convener for education and equalities Paul O'Kane said: "This is a very significant investment by the council.
"It will give the people of the area a great place to meet, get fit, learn, read, relax and do business."
Barrhead's existing library is to relocate until the new development is complete. Its current site, in Church Road, is to form part of the site of a new Asda superstore. The council say information about the library's relocation to temporary premises in the town's Lowndes Street will be confirmed soon.
In Barrhead Sports Centre, the sports hall and stage area will close in autumn to allow the major works to start.
It will remain closed for around four months, with groups who use the current facilities temporarily relocating to other areas. The gym and pool will remain open.
The new centre is expected to open in autumn next year.
