You may also find out after looking at several sets of stock house plans that one is your dream house. Depending on your house building plans, this could save you thousands of dollars in architect fees. If you do order a set of stock house plans, check with the company first to see if you can exchange them later if you want a different plan. Some blueprint suppliers will give you up to 90% credit toward a different set if you return the original plans.
There are a few aspects that you must finalize in your mind, before looking at the different online designs. You need to visualize the structure of the house with respect to whether there should be a basement, how many storeys you would like to have, the number of garages that you want, whether you wish to have any outside water pond, the size of the house, the sizes of the different bedrooms, kitchen, living area, etc., and the amenities that you want like bathroom tubs, sinks, and fireplace.
Drawing a good set of custom home plans involves integrating many different concepts and ideas into a solid and usable working plan. Many designers are able to come up with a unique or interesting preliminary design, but fail to deliver when its time to detail the house structure. They draw a pretty picture but have little or no understanding of how to translate that nice design into a working plan which the builder can understand.
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.
