Architect Dermot Bannon takes on a 1970s bungalow classic in Kells, County Meath, owned by newlyweds Sarah Clarke and Liam Callan - a hard-working couple who know exactly what they want. However, their wish list is far more ambitious than their budget. Undeterred, the couple hold firm on a fourth-bedroom extension - complete with a TV wall, where Dermot is picturing elegant French doors.
