The older homes built in 1958-59 (many of which catered to the sizeable influx of Commonwealth Public Servants' families, who were being relocated with their respective Departments' headquarters from Melbourne), now sit beside modern townhouse developments, while individual blocks are being 'gentrified' by either extensive renovation or demolition and rebuilt homes.

A scenic wetland was built adjacent to Sullivans Creek in Lyneham to improve downstream water quality.

[5] Many of the single houses between Sullivans Creek and Northbourne Avenue have been replaced by two and three-storey flats in recent years.

The original residences on "old" Lyneham, contained within the area bounded by Wattle, Dryandra, Archibald and Mouat Streets and Northbourne Avenue mainly date back to the late 1950s.

North Lyneham's main feeder road, Cossington Smith Crescent, loops through the area with other streets coming off it.

The walking trails in the reserve are popular with the local residents and provide scenic views of the inner northern suburbs of Canberra to the east and south and Belconnen and the Brindabella Ranges to the west.

Lyneham is favoured by students and young adults with 34.5% of its population in the 20- to 34-year-old age group (compared to the Australian average of 20.5%).

[1] Lyneham is located within the federal electorate of Canberra and it is represented by Alicia Payne for the Labor Party.

In the ACT Legislative Assembly, Lyneham is part of the electorate of Kurrajong, which elects five members on the basis of proportional representation, two Labor, one Green, one Liberal and one Independent.
