Peter Berkin and his wife Chard have decided to build a new home at the bottom of their garden. Problem is, right from the start they can't agree on any part of the design - even the basic shape. Peter wants the new house to feature a workshop where... (more) he can build a plane. He wants the house to be round. Chard however wants it to be square and practical. Peter aims to spend £400K, Chard wants to keep the budget around £200K. With Peter building as much of the house as he can himself, helped by his mates, and Chard taking control of the money and schedule, it looks like a recipe for disaster.
