[7] The 1925 sub-division plan submitted by new owner and land developer Robert George Oates, incorporated Roman street names.

[citation needed] Between 1912 and 1926, the southern edge of the suburb was serviced by the Belmont Tramway which connected with the Queensland Government Railway at Norman Park.

[citation needed] The service was reinstated by the Brisbane City Council in 1925 following the amalgamation of the local government authorities, but was again suspended in 1926.

[9] In 1953, the Brisbane City Council commenced a trolley-bus service, which connected the suburb with Fortitude Valley via Stanley Street, terminating just off Oateson Skyline Drive.

[10][11][12] On 1 June 2001, Seven Hills was gazetted as a suburb by the Queensland Government, following a push by local residents to have it recognised independently of Norman Park.

80.6% of people living in Seven Hills were born in Australia, with the next most common countries of birth being England (3.6%), New Zealand (3.6%), South Africa (0.8%), India (0.6%), and the United States (0.6%).

90.3% of people spoke English as their first language, while the other most common responses were Japanese (0.6%), Mandarin (0.6%), Spanish (0.5%), Tagalog (0.4%), and German (0.4%).

[citation needed] There is a network of narrow, and generally steep heritage walking paths located within public easements between residential properties.

Aside from a small number of local parks, the major recreational walking attraction is the 52 Hectare Seven Hills Bushland Reserve located on the north east side of the suburb.
