The land around the Parramatta River was used primarily for farming, with the Concord region becoming an important area for agriculture due to its fertile soil.

A major historical figure in the area was Thomas Walker (1804–1886), a philanthropist who lived in the Victorian Italianate mansion, Yaralla, on the shores of Parramatta River.

The hospital—known as the Thomas Walker Hospital—was designed by Sir John Sulman in the Federation Free Classical style and built on a large site north-west of Yaralla.

Since the late 1970s, it has functioned as Rivendell Child, Adolescent and Family Unit, which specialises in the treatment of young people with psychological problems.

In the early 20th century, Concord West remained a relatively quiet suburban area, with a mix of agricultural and residential land use.

However, following World War II, suburban expansion began in earnest, and the area grew rapidly as more people moved to the suburbs for better living conditions.
