The Victorian category comes into focus as Kevin McCloud and Anna Keay present more building restorations in the running for the Royal Institution of Chartered Surveyors' Restoration of the Year award. Anna explores Mount Stewart, an imposing country house in Northern Ireland, and Wilton's Music Hall in east London. Architectural historian Jonathan Foyle visits the Pump House in Barry, Wales, and historic building surveyor Marianne Suhr looks round a medieval-style castle in Stornoway in the Scottish Highlands. At the end of the programme, it is revealed which buildings have been chosen to make the final shortlist.
