On Monday, April 18th, 1921, Ben Avon’s new $42,000 Municipal building, located at the corner of Church and Forest Avenues, was opened for public use. The second floor of the structure was furnished by public subscription at a cost of $3,000 and put to its first use the following Saturday by the newly formed young men’s club of Ben Avon.
The building, which is red brick and of colonial design, was built with a view of service to the community. The council's chamber, police headquarters and firemen's rooms were situated on the first floor. The fire apparatus was housed in the basement of the structure.
The second floor, initially known as the Memorial Room, was used by various groups including the War Veterans Club and furnished with a pool table, piano, lounges and game tables. Over the years the room was used as a serve-yourself library and community meeting space.
