Here are my thoughts at first glance. I'm not an expert, I just enjoy thinking about processes/flow. :)

1. The family entrance through the garage is through a tight laundry room. There is no where for you to put your coats/shoes/purse/etc, and nowhere for you to sit down while putting on or taking off shoes. The only place I can imagine this working is Phoenix in a home with all ceramic floors where you wear shoes inside the house.

2. When you enter your sanctuary, the first thing you'll see is dirty laundry. You deserve something a little more special. :)

3. Your guest entrance has a closet and no where for guests to sit while putting on/taking off shoes. It's actually a LOT like my current house's entry, which we HATE. I do not like guest coat closets--I think a bench with a wall of hooks are more guest-friendly.

4. I would pick ONE entrance onto the deck (probably the dining room one). Every entry point will be an entry for dirt/debris.

5. I'm not sure I would spend the money having windows on the side of the garage. It depends on where you live, but I have noticed that in my parents garage with windows, flies get in, then bang their heads endlessly on the windows trying to get out. My garage has no windows (not even on the doors) so the flies are able to escape through the same spots of light through which they entered. Kind of a random observation, but it is SO nice to never have flies in the garage (which means we have a lot fewer in the house as well).

6. Is that a fireplace or a TV in the great room? If it's a fireplace, think about where you will put a TV. I don't know anyone who enjoys watching a TV mounted over a fireplace because the angle is so awkward. I do know some people who simply don't watch TV, so they have the furniture arranged to stare at the fireplace. That's charming, but just not realistic for us because we are movie fans. :)

7. I like your kitchen work triangle (prep area, sink, stove). That's how I cook, with just one trip to the fridge/pantry at the beginning of the recipe. I see that you do NOT have a pantry. Will you do a cabinet-focused pantry? I love the look and functionality of those, but they are either inefficient OR you spend a lot of money designing them to use the space efficiently.

Try to take your second one (I think it feels more spacious) and do this rearrangement:

Take out the stairs, and expand the bathroom into that space. Include your laundry in this room.

Move the stairs to the right side of the foyer taking some of the space of the coat closet and the laundry room.

See if that fits for you.

The goal: You still are turning your stairs to under the bathtub. That just simply won't work. A tub bottom is not forgiving when it comes to shaping headroom for the stairs...

Thank you for your comments. Minneapolisite, we are not in Phoenix, but we are in Arizona and will have tile and hardwoods throughout the house. We don't take our shoes off in the house or expect our guests to, so I'm not too concerned about a seating area in the entry, although I might put a stand-alone bench or seat there. Flies aren't a problem here either so I think we'll have windows on one side just because my husband likes to work in the garage occasionally.

Here is a new plan with the stairs moved to the garage and the laundry to the guest bathroom, but I need suggestions on how to arrange that bathroom - I'm not crazy about having the laundry in the bathroom. Could it be sectioned off or maybe enclosed with doors?

Thanks again for your help.

I like this last plan, but you shouldn't have the door to the basement stairs, swinging into the stair area. If you added just a bit more room, you could have a pocket door. I would move the laundry back into this space (where you have the closet) and make this your laundry room, again.

The hall bath could be a bit smaller (keep the door with side lights...it looks great!) and put the closet where you hve the toilet now.

I really like the bigger kitchen island, but I'd think about putting the pantry on the other side of the fridge and adding a corner sink to your layout, where you have the pantry. It's nice to have water closer to the fridge and it would be handy to the range, too. Just an idea :)

What is your actual dimension, right now, for the bath/laundry. (and yes, you can easily get them enclosed in a closet.)

Also, your placement for the stairs isn't really what I was thinking. Not sure if it would work, but you can decide that.

I was thinking to have them run "N-S" (top to bottom, in this drawing, assuming N is top here), and put them along the foyer right wall/garage left wall.

Remind me, upstairs? or downstairs only?

Aha! Since you're in Arizona your entry points make more sense. My parents have a vacation home outside of Phoenix and we all wear our shoes inside there. They don't have a good spot for coats/shoes/bench and I've never even noticed. :)

You have room in the bathroom/laundry to put the toilet next to the bath where you have the linen drawn--privatizing it a little. Then, you can have a larger vanity cabinet if you'd like with countertop (a little more room for folding if you want).
Or, keep the linen closet and have that function for some laundry functions (ironing, etc).

Is there a reason you are wanting to use a single double door for the garage instead of 2 single doors? Using 2 single doors might solve your "off center" problem and also be more functional.

Thanks, Kirkhall. I hadn't thought about two garage doors. Do you think the stairs work there with access from the entry? I think 15 feet is allowed, but would need space at the top to start down the stairs.

I'm not a stair length expert, but I do like this general placement better than your others.
