Tons of good advice regarding interior aspects of new construction. I’m going to mention some things I think about in positioning a home and exterior issues.
Outdoor spaces (decks, patios, fire pits) work better in the east side of a house to allow for shade and sun protection in the afternoons/evenings.
If you are a gardener, get sunny areas for food gardening with attention to soil compositions and drainage issues.
Driveways will clear off snow faster if on a western (and better yet south western exposure, with no trees shading the driveway. Take advantage of Mr. Sun when you can. I’m not familiar enough with SLC enough to know what the regular snowfall is like (it did host a Winter Olympics) but natural snowfence can help driveways stay clearer as well.
Explore the option of well water for watering outside, or even using inside.
Privacy concerns include nosey neighbors and road lookie-lews. Fencing, berms, and screening vegetation (@1pointer used some high growing cane/grass which I thought was genius) can induce serenity and privacy.
Does your state or local community have assistance in installing solar systems? We had a system to heat the house, hot water and dump heat into a pool which on cloudless days in the depth of winter would heat the house to 85-90 degrees, requiring us to open windows to quit sweating.
External water supply points so that you don’t need to drag hoses everywhere. Underground sprinklers if desired, or consider larger areas of xeriscaping......drought in the west is a constant. Consider volume storage of snowmelt/rain. (Could become a water source in cause of emergency outages).
Storage locations for firewood, yard tools, machines and gardening stuff if not stored in a garage.
And speaking of garages, I’ve never had a space that was too large for my needs or desires. Good bigger than you think.
