Further to the east lie the wards of Pontprennau & Old St Mellons, Rumney, Pentwyn, Llanrumney, Llanedeyrn and Trowbridge. The last four are again largely of public housing stock, although a large amount of new private housing is being built in Trowbridge. Pontprennau is the newest 'suburb' of Cardiff, whilst Old St Mellons has a history going back to the Norman Conquest in the 11th century. The region that may be called "Rural Cardiff" contains the villages of St. Fagans, Creigiau, Pentyrch, Tongwynlais and Gwaelod-y-garth. In 2017, plans were approved to create a new suburb of 7,000 homes between Radyr and St Fagans; known as Plasdŵr. St. Fagans, home to the Museum of Welsh Life, is protected from further development.
