Another item which is often missing or lacking in a set of house plans is comprehensive and accurate dimensions. We have always strived to provide more than the minimum amount of house dimensions so that it is easy for the owner and builder to layout a home on its building site. We will even calculate point to point dimensions (using trigonometry) for homes which have lots of odd angles to them (as opposed to a simple rectangle layout). Not all architects or designers will go this "extra mile," so it pays to check these things out beforehand.
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 been in the business for more than 30 years, we have seen a large number of house plans which looked good at first glance. However, upon closer examination, many of these plans were found to be lacking large amounts of needed information. If a house plan is not easy to navigate or is not thoroughly detailed, then the builder is left to guess at the designer's intentions. This often means that he will "pad" his bid to make sure that he covers any unknown construction costs that may arise.
Where to find small house plans : If you are interested in small house plans you should always look for the best deals on blueprints. Blueprints or plans are available from a variety of sources and at many different prices. Two of my favorites are coolhouseplans.com and dongardner.com. Plans from coolhouseplans have prices ranging from $585 for five sets of blueprints up to $1,175 for CAD files. If you are not familiar with CAD files, these are Computer Aided Drawing files, meaning that they provide all the information needed to build the house on CD-ROM and have blueprints that can be printed and as often as needed and in any quantity.
