Every set of custom house plans includes several items which need to be blown up and detailed for further clarification. If a set of plans does not provide additional close-up drawings (for things such as beam connections, deck railings, stairway construction, etc.), then it is not a complete set. It is very easy to cut corners during the planning process. But the end result will be higher costs for the home owner - and lots of frustration for the building contractor.
If you find a house plan that you love, but want to make minor changes, most companies can have their designers do that for you, at an additional fee. It is also possible to have your plans reversed, for instance, if your breakfast nook faces west but the view from the north side of your lot is more attractive, you can reverse it. Many of the sites selling house plans will allow you to see a reversed view, of houses you might want to build.
Having a custom drawn designed house means a professional architect applies his skills limited to the individual homeowner's needs or what they have in mind. Factors considered in such a situation are the size of the site of construction, ideas of the individual homeowner, population around the area, and the nationally and locally existing building code plans. Time is also a considerable factor for completion of a custom designed house.
Some small homes have two floors and come with or without a basement. Some more common small homes have crawlspaces for extra storage. Traditionally they have a room off the kitchen which you can place a washer and dryer. These house are frequently Cottage or Bungalow style.
