Question: how much does it cost to change the layout of a house?
Answer: A general pricing guideline, as noted on our ePlans.com Modification Guide, is as follows: small changes tend to be in the ballpark of $500-1,000, plus the cost of the plan; medium-sized changes are often $1,100-1900, plus the cost of the plan; and major changes can be $2,000 and up, plus the cost of the plan.
