We have found that percentages adjust for smaller budgets versus larger ones. The reason for this is simple, fixed costs such as utilities don’t drastically change whether the home is 1000 square feet or 10,000 square feet. What does change, however, is building materials and fixtures. In an effort to provide the most realistic figures we have provided percentage breakdowns for projects under $500,000 and one for projects over $500,000. $500,000 seems to be the point at which homes go from cozy cabins to luxury log homes. **In both examples land, architect fees, landscaping and unknowns such as extra-long driveways are not accounted for.
