Mrs. Adam and her husband, Tim, are planning their dream house. The land for the house sits high on a hill with a beautiful view of the nearby mountains. The plans for the house show the size of the house to be 300 square metres. The average price for a lot and house similar to this one has been $1500 per square metre. Fortunately, Tim is a retired plumber and feels he can save money by installing the plumbing himself. Mrs. Adam feels she can take care of the interior decorating.
