We've gotten quite attached to having good old Dermot Bannon fixing up gaffs of a Sunday evening, saying "we need MORE LIGHT" and such, but sadly tonight is the final episode in the current series. Hopefully they have saved the best until last though as Dermot helps a Dublin couple transform a 1970s house that has remained largely unchanged since it was built. Dermot proposes adding a steep-roofed extension, but his plans upset the neighbours, who fear their garden will be overshadowed, while - shock horror - surveyor Lisa O'Brien struggles to incorporate it into the budget.
