The former Grantham Town Hall was built in 1950 by local architect Lionel Hesson. The building is two storeys tall, with a full office, built of brick with a stone façade. It exists as one of the few institutional buildings designed in a contemporary international style with some Art Deco features that was growing in popularity at the time. The building has remained unchanged since it was constructed and includes a crest of the township's coat of arms carved into the stonework above the entrance and the front doors and iron pole lamps are original.

The post war years and the automobile brought great change to the urban form of St. Catharines due to the rise in the suburban lifestyle and improved general standard of living for many people. In 1950, the construction of the Grantham Town Hall building was complete. However, Township officials had only 10 years to enjoy this new office space when their occupancy came to an end in 1961. This is because during the 1950s, St. Catharines began to spread its boundaries in all directions with land being added. Therefore, in 1961, the towns of Merritton and Port Dalhousie, and parts of Grantham Township were integrated with the City of St. Catharines.
