Average Home Building Costs Per Sq Ft: Shell Option. The average home building cost per sq ft for a home is far more uniform than the finished cost per square foot. A shell does not include the foundation, landscaping, fixtures, cabinetry finishes or appliances. Sometimes it does not even include drywall. It usually doesnât include the plumbing or electrical wiring either, though sometimes rough plumbing and wiring are included. The average home building cost per sq ft for a shell is about $25 per square foot with a range of about $22 to $30 per square foot.
Cost to build a custom home is expressed in price per square foot estimates. In the housing market, we express the cost to build as a price per square foot. Therefore, a 3500 sq. ft. house that costs $700,000 would have a cost of $200.00 / sq.ft. Land is not included in this price. However, building permits, architectural and designer fees, as well as all construction-related costs are included in the price per square foot calculation.
