With all the sq ft listed (8450) assumed as living area, and assuming 4 small appliance circuits, 1 laundry, 1 dryer, 1 fridge, 1 freezer, 1 dish washer, 1 water heater, 1 microwave, 1 range, 2 heating units and 2 AC units...
My demand load calcs out to 171.1 Amps at 240V (41,067.5 VA), and I'm over calculating it, not by code minumums... Which would convince me that a single 200A service would suffice.
I usually ask customers, is your electric bill more that $1000 a month? If not, then 200A is plenty.
Not meant to nag or flame, just curious as to the over-design. Are you planning on using welders and such in your shop?
That would make all the difference!

This is a great forum and based upon what I have read, I see conscientious contractors who desire to do things right. Over the years I became more and more disgusted with owners and developers who insisted on bare minimums for electrical installations. I actually had a developer tell me “I don’t give a damn about quality, I just want the light to come on when I flip the switch”. I declined to participate in his project. As I had the time and resources I tried to envision every possible remedy for the myriad of shortcomings that I witnessed during my active years and constructed accordingly. A lot of what I included has roots in commercial and industrial. There is a large amount of metal raceway indoors and PVC underground. Some items are things that I wanted to include in projects but owner’s budgets negated those frills. Electrical is not the only area where innovation was dominant. My residence has been toured by IBEW apprentice classes, NAHB groups, engineering classes from a nearby university, and several inspectors both during construction and following completion. Another item that may be of interest to the forum: In the rural county where I am located, there is no electrical permit required nor any building inspection except for the sewage treatment system. I have been actively pursuing the county to institute legislation to require permits and inspections. It’s difficult as the farmers don’t want an inspector telling them they cannot wire their barn with zip cord. BTW, I retired 10 years past and still assist small contractors in the area in mitigating problems.
