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 Co. Meath where a young teacher is planning to move into her grandparents' old 19th-century farmhouse before her wedding. Dermot Bannon discovers the property is outdated, cold and cramped, and begins making plans for a single storey extension. However, as we've come to expect, costs soon escalate as major problems are discovered with the drains and septic tank.
