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.
Pre-drawn house plans are those that are drawn by architects or home designers and then offered for sale, unlike those that are drawn for an individual, with input from the customer. While this method may be a great idea, there are definite benefits to purchasing pre-drawn house plans. Architects and home designers that do custom home designing also do a lot of their own designs, and it is these plans that are offered for sale, They are adept at making plans that utilize available space to the best possible advantage, and at laying out a floor plan to optimize curb appeal.
In addition, good stock plans come with a detailed inventory, which you can use while you're developing out your dream house. This is important for two reasons: you can look at the materials used to build your house and determine whether your budget will stretch to accommodate them, and you can get a very good idea of where to upgrade and downgrade materials.
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.
