5. Have a plan. A sure way of busting your budget is to defer decisions or, as they say in Washington
, "kick the can down the road." Construction has started and you haven't made nearly enough decisions about what tile, what plumbing fixtures, what trim, etc. The builder starts pressuring you to make decisions or, worse, just does something without your input. You may find yourself tearing out work or, worse, have to live with something you really don't like because you don't have the time or money to change it.The best way to avoid these nightmare scenarios is to have your architect and/or designer prepare a detailed set of drawings and make all of your decisions before starting construction. Then, don't change your mind. It's easier said than done, but preparing a plan and sticking to it is the best way to stay on track.
