Taking the plan from blueprint to dream house : A builder may provide a ballpark estimate of construction costs from a study plan, but he or she should consult the working drawings to give a more accurate figure. Many variables can affect the bottom line, including the choice and availability of materials, labor costs, choice of finishes and degree of detail. Ask several contractors for competing bids. If you've got the vision but not the bankroll (at least at this time), it may be wise to choose a plan with bonus space that can be built out as finances allow. Be sure to allot a portion of your budget to landscaping and finish details. Architects and interior designers recommend that you don't skimp on the seemingly small stuff. Higher-quality trim and building materials may trump extra square footage. "Good, insulated windows may be costly initially," Martin says, "but over the long run, they're going to save you money on your power bill." Crown moulding and custom cabinetry can make a stock plan feel like it was designed specifically for your family. After all, it's the personal touches that make a house feel like a home.
One item to look for when evaluating a house plans' quality level is the number of structural sections which are shown on the plan. Highly detailed sets of plans will always cut lots of sectional views through the house to show every different roof framing situation. This might mean that 10 or 12 (or even more) sections need to be drawn for a large house plan. And even a small house plan should include 3 or 4 sections minimum. However, many home plans available today (especially plans purchased through inexpensive plan directories) cut corners in this department and only show one or two house section views. This means that the builder will have to guess at the rest of the house framing.
Reproducible Set - You can buy a reproducible set if you think you may need minor changes made to your home plans. You can make copies from this type of home plan, but you are not allowed to build more than one home from these type of plans without a separate license.
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.
