The Fitzgibbon suburb boundary extends to where the railway line crosses Cabbage Tree Creek. In the pocket bound by Beams Road in this southernmost corner of Fitzgibbon sits Golden Downs, a retirement living community.

In 1992 Golden Downs, an over-fifties community of 231 homes south of Beams Road and close to Carseldine Station, became the first purpose-built relocatable home park approved by Brisbane City Council. Keith Beavis and Carl Benedict Bartels owned retirement homes under the Golden Downs business name. Since June 2009 the land lease operator Serenitas Communities AB Pty Ltd, which develops and operates lifestyle communities for people over fifty years old, has been the trustee.
