In Ashford Co. Wicklow stands the house of Nigel and Frances Coffey. Frances's parents live next door. Several years ago her father built a private road and gave seven plots of land to his seven children. The house is a typical 1990's bungalow, built from a handbook. It was perfect for them 20 years ago, but with 5 children ranging in ages from 9 to 26 and with girlfriends, friends, a dog and family living nearby, the house is just too cramped and they struggle for space. They want to build their dream home and their budget is 450,000 pounds. For the first time, Dermot comes under budget. However, things begin to take a turn when the couple start adding to what they originally wanted.
