Time for Ireland's favourite architect to get renovating another home tonight. There's a house that needs more light? He's your man. Have an idea of what way you'd like your new kitchen to look? He won't listen, but he's your man. Tonight, good old Dermo' is in Sutton to help a resident redesign the 1960s house she grew up in as a new home for her family. Dermot proposes building a large extension with a mezzanine, but when surveyor Lisa O'Brien examines the plans, shock horror, they turn out to be more costly than expected.
