There are three main reasons why every thoughtful person who builds a house should have complete blue prints and specifications:
First: So that all changes, if any, may be properly made on the plans before the construction work is begun.
Second: So that disageements and misunderstandings during the course of construction may be avoided.
Third: So that the home when completed will be exactly as represented in the picture and plans.
Everyone should beware of the carpenter or contractor who claims to be able to do "just as well" without plans, or with pencil sketches. Such claims denote inefficiency, or a desire to "get by" with his own methods of construction, which are never as good.
Reliable contractors invariably insist on complete plans so that satisfaction may be guaranteed.
