Charnwood's estate design was based on the Radburn principle. Under this design, houses were to face common parkland, with the suburb's streets servicing garages situated at the rear of the houses. The design failed in its application, however, as home owners built fences around the "park side" of their blocks, effectively screening the houses away from the common parkland. This created long, narrow, fenced walkways, with poor lighting and no neighbourhood surveillance. The original design for the network of pathways was to make it possible to walk from any point in the suburb to any other without directly crossing a road; pedestrian bridges can be used to cross the few major streets within the suburb. Charnwood is the location of the Charnwood centre shopping area which serves surrounding suburbs. The shopping centre includes several fast food outlets, a branch of the Labor Club, a Shell Service Station and a Woolworths. An emergency services station incorporating ambulance, fire and rescue services was opened in October 2013 by the Minister for Police and Emergency Services, and is located near the Charnwood shops at the south-west corner of Lhotsky Street and Tillyard Drive abutting Ginninderra Dr.
According to the Act Planning and Land Authority website, the suburb is named after: " former homestead in the Belconnen District; Henry Hall obtained a grant of of land which he named 'Charnwood', 1833; named after the Forest of Charnwood in England." Street names in Charnwood are named after New South Wales pioneers and the suburb name 'Charnwood' was gazetted on 9 September 1971.
