Having one team coordinate design and construction means fewer handoffs, more accurate planning, and less risk of costly changes later.
You hire an architect or designer to develop your plans, then take those plans to builders for pricing.
One company manages both design and construction, with building costs and site requirements considered as plans are developed.
When plans are developed without input from a builder, the cost to construct the home may not be clear until the design is finished. If bids come back higher than expected, you may need to revise the plans and go through another round of pricing.
Work with McMahon to design a custom home around your needs, your property, and your budget.

McMahon’s custom homes generally range from $200 to $450 per heated square foot, excluding land. Your home’s final cost depends on its size, your property, and the materials and finishes you select.
After your design, specifications, and selections are complete, McMahon prepares a fixed-price proposal for construction. This establishes the price for the agreed scope of work before construction begins. Changes to that scope can affect the final price.
Josh brings more than 20 years of homebuilding experience to McMahon Custom Homes. He stays involved throughout your project, from the first site visit through construction.
Carolyn oversees the preconstruction phase, helping coordinate the planning and details that need to be worked out before building begins.
