When contracting a custom remodeling or new construction project, this simple question cannot be answered due to so many variables. Selections, made by you, may add costs to the project but will not add any square footage.
For example, a 2500 square foot house can be built for $250,000 or $400,000, depending on many variables.
Here are some questions to take into consideration when determining cost for remodeling and new construction projects:
Is the lot severely sloped? This will add additional foundation cost and site preparation.
Will the home be built on a slab or on a crawlspace?
Will surveys be required by your lender or to site the home?
The cost for building permits and fees vary greatly by municipality. In what county is the home being built or remodeling taking place?
Are there any Architectural Review Board fees?
Will you require a well or septic system or both?
