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 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 pounds 400K, Chard wants to keep the budget around pounds 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.
