Out door set of the long-running Welsh language soap opera Pobl y Cwm. In 2012 fiming moved to a new set at the Roath Lock studios and in 2018 the set was demolished in advance of the move of the BBC from Broadcasting House.

The set sits on the north side of BBC Broadcasting House in Llandaff, and consisted of two short roads in a T-formation. Along the roads were located a series of shallow building fronts including houses, the Cwmderi Bank, a lauderette and fish and chip shop.
