I would like comments for changes before I proceed to builder. The house will be in a northern climate so snow and ice are considerations. Also plan to retire there. Image link:

Landrey-great job on the plan! I think that's why you didnt get alot of responses initially. There are only a few things I see that I would do differently other than those mentioned above. -I would move the powder room into the mudroom area. Reduce the size of that giant walk-in closet in the guest room to about 4.5'-5' wide by sliding the mudroom wall to the left and move the closet entry over toward the side wall of the bedroom as far as you can. You should have enough space to do a 1/2 bath there. My reasoning for this is that right now if someone is outside playing/working and needs to use the bathroom, they will often come through the garage and now have to traipse all the way through your house to get to the powder room potentially leaving a trail of dirt/mud/debris behind them. Or they can come in the front door and trail dirt/dust/debris through the foyer (granted a shorter trail.) Just my $0.02. Laundry room upstairs--I'm guessing that's a counter next to the W/D? How big is the sink you're planning to use? I would shift the W/D down to where the sink is and run a counter from the end of the W/D to the corner and then down across under the window. I'd put the sink next to the W/D with a sink base cabinet and hanging space above then I'd put pullout hampers along the short wall like these: Reasoning--that's a small space and as the kids get older, the laundry only gets worse. Having an efficient space that easily allows for sorting and storing the dirties, as well as allowing for plenty of folding and hanging space will help keep the laundry (and potentially the rest of your house when it comes to laundry) neater & more organized. I think you posted the kitchen in the kitchen forum and asked about building in a regular sized fridge or making the counters deeper. Personally, I wouldn't make the counters deeper--that will significantly increase your cabinet & countertop costs. Since you have the fridge placed on an exterior wall, recessing it back likely won't work as you need space for insulation in that wall. I'd suggest either going with a counter depth fridge (we love ours & I was really worried about going from full depth to counter depth--link to ours below) or moving the fridge to the opposite wall where the bar sink is and you could either leave the bar sink there or move it to the island. Hope this helps! Here is a link that might be useful: mydreamhome's CD Fridge

will it cost that much more to remove old foundation?! If it's just concrete, no sweat for the backhoe. As above, it's hidden oil tanks, septic systems and underground streams that are of most concern. Even on the infill city lots I've built on, those surprises are always in the offing. We found a partially-filled oil tank in one; quietly and very quickly removed. Not from the 1955 house we demoed, but from something earlier. In another, we hit the corner of an underground stream that we channeled into the city storm connection. Not to mention the 19th century manure from the barnyard that became our front yard. A friend in the UK started renovations and discovered his home was built on an ancient Roman graveyard. Requiescat in Pace. In the oldest known city in the world, Çatalhöyük, archaeologists documented 18 levels of dwellings over 1,500 years. You're rarely the first.

Doesn’t seem like there are any other suggestions for questions to ask. I understand everyone is mostly on board with just trusting blindly and letting them go. I’m an engineer so I’m constantly asking why things are done a certain way and 100% believe in trust but verify. My nature has me always questioning things. I appreciate the input and attempts to build confidence. I think I’ll still ask some of these questions and the builder can answer or has his subcontractors answer them. I’m a curious person by nature.
