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.
Another service provided by the companies that design and sell house plans, is one that allows you to estimate the cost for building a particular house in your area of the country. The South is the least expensive area to build in and the West has the highest cost .The national average is somewhere in between.
Why do this, since even stock plans cost you at least a couple of hundred dollars each? Because the right stock plans can save you tons of time and money if you have a talented architect. Most plans are at least partly modular these days, and often you can even order prefabricated sections pegged to a specific house plan.
Square one : The real estate agent's mantra "location, location, location" rings true even when you're building from scratch. From privacy to orientation, your lot is likely to influence which plan you choose. "Theoretically, it's best to start by finding a lot because then you'll have a clear idea of what square footage will and will not fit on the property," says Robert Martin, Architecture Editor at Southern Living. "It's a dangerous proposition to try to gooseneck a house into a lot that's really not ideal for that plan."
