The original settlement of Brookside is a Radburn estate built in the early 1970s as part of the development of Telford New Town and is entirely within the confines of Brookside Avenue, a 1.7 mile ring road. Significant development has taken place around the outside of Brookside Avenue since the estate was built, the majority of which is part of Stirchley Park but falls within the Brookside ward for both Telford and Wrekin Council and Stirchley and Brookside Parish Council.
