It is a relatively modern area with housing stock dating mainly from the late 1980s and beyond. The area has a centralised precinct providing services, comprising a community centre (Thornhill Church Centre), a Sainsbury's supermarket, with an integral Post Office and Pharmacy; and a Medical Centre.
There are three public houses located in Thornhill: the Old Cottage, Pendragon, and the Ffynnon Wen. Though on Thornhill Road, The Traveller's Rest to the north is on Caerphilly Mountain and in Caerphilly based on its postcode and council locale.
Thornhill Cemetery is a major cemetery located in this area of Cardiff. Thornhill crematorium was built on this site during the 1950s as a dedicated crematorium. This differs from the crematorium that was set up in nearby Glyntaff; this in contrast was a chapel that was originally used for traditional burials and modified to serve as a crematorium.
Most of Thornhill's residential development took place during the 1990s, Cardiff County Council originally planned Thornhill as "The Villages of Thornhill"; with clusters of houses interspersed by large "green" areas. These green areas were short lived as rapid housing development resulted in homes being built in areas adjoining the "Villages".
Thornhill also houses a few tucked away historical sites including the remains of a castle situated close to the Caerphilly/Thornhill border known as Castell Morgraig.
Thornhill is served by bus services operated by Cardiff Bus, . The 27 and 28 service runs through Thornhill and terminates at the Central Bus Station at regular intervals. Stagecoach Service A and B runs every 30 mins from Cardiff Central Bus Station and stops outside cemetery. NAT Group have its X8 services, running from Thornhill to Cardiff city centre and onto Cardiff Bay.
The area is served by Thornhill Primary School. The nearest secondary school is Llanishen High School. Welsh medium education is provided most locally at Ysgol Y Wern in nearby Llanishen and Ysgol Gyfun Gymraeg Glantaf in Llandaf North.
