We made the plan with everything as we get older to be on the first floor. Master bedroom, laundry, utilities, and kitchen are all on the first floor with no steps for entry into the house. Second floor will have three bedrooms, a large bathroom, and a pretty large living area for the three kids to go crazy. Main shower is also going to be ground level with a bench for when we're broken
Luckily I believe we are far enough out of town that the urban sprawl won't be an issue and I'll eventually own the rest of the 80 acres surrounding to insure we don't have to deal with too close of neighbors.
Gary we are down along the Nebraska / Kansas border but yes south of Omaha. We are having a local company that mainly does agricultural buildings but has now for quite some time been completing residential/commercial buildings. They are SIPS panels. They pretty much complete the shell and we have worked to outsource most of the interior subs/decisions which has been quite a feat while raising kids and working full time.
I had looked into typical stick builds in this area recently (we've been shopping around for 4-5 years) and was quoted by numerous builders for $750-900k for a 2000 square foot house depending on basement without much more than a single car garage. We were able to get about 2880 square foot living and 1280 square foot shop for a sizeable difference. We had priced acreages that were already established around here as well and most were 500-600k before you likely needed to update most of the old farmhouse that sat on the acreages. The good news is we get to build it exactly how we want it.
