I am not a guru but I can give you my opinion. Melanie on the regrets - while trying to minimalize them they still will happen! Flip side is you will likely also have some grrr that ends up turning out different but BETTER than you imagine. IMO stealing the foot makes it much more functional so I would do it in a heartbeat but I am not the expert. It also opens it up and will 'feel' better. I think that's a good spot for a broom closet and charging station and should easily stay tidy. It is about 5' wide yes? That is a nice size space. Measure what you have you want to store in there and then look for pics of what you are thinking. Utility sink in the garage - really in the winter there isn't much dirt and when it's exposed it's frozen too so I'd think the utility sink would get more use in the spring summer fall when it's thawed so I'd keep it on the table too. My opinion - your money. Ha! As far as 'enough room' - it sounds like your kids are younger based solely upon still being in the 'add more' season of life. :) I can tell you only to think seasons, think sports, cleats, basketball shoes, church shoes, boots, hiking shoes, tennis shoes, flops, bats, ball caps, backpacks, lunch boxes, water bottles (if you have girls think even MORE shoes and then purses - ack)........ I will say for my 2 the space we have is more than adequate and it's quite roomy (I just double checked and it's actually 6.5' on a side so each person has 3' plus). That said we also have a closet near that I put off season stuff in and dog food. Winter coats and snow pants and boots are not in the locker area all year. I put them in the closet over spring/summer/fall. As long as you have a spot for that I think you are fine. Off season can closets can always be in the basement as well. There are always sweatshirts hanging and ball caps. Besides that there is always a stray nerf gun, goggles, flash lights and what have you hanging out there. I don't mind it there - it's out of the way and not underfoot! Old house it used to be in their rooms and all over. We had no designated space for outdoor wear anyplace besides bedrooms. If I am feeling brave I will snap a real life pic of it in action. It is easy to pick up and look presentable when needed but typically M-F it's a dumping spot. I like an open bench vs doors because we do use it to sit down to put stuff on and take stuff off regularly. And when our parents come and use that entry they love to be able to sit down to put on and remove shoes. It's comfortable and useful. With your window placement in the bathroom and the exterior door you will find it a nice light filled space. Our exterior door there is 3/4 glass and I love how it lights the hall. It is never a dark space.

Do you have a separate Dining Room (this is where it would help if we saw the layout of the entire floor - both here and on Kitchens - not just the addition, the entire floor). I'm asking b/c if you do, you might consider making the table space a banquette and taking more space for the Powder Room. (Bench along the Powder Room and, possibly, "top" walls) Regarding the laundry - I'll be honest, I would not want my laundry anywhere where guests could see it - and putting it in the Powder Room means guests will definitely see it! It might help to build an enclosure around it - it would at least hide the washer & dryer, but it wouldn't help with any laundry sitting in the room - clean or dirty. Note that expanding the Powder Room may mean going with the narrower window (8'+ vs 10').

Ask and you shall receive.... The Kitchen and stairs are located as follows: For reference, the garage would go to the left of this, past the back of the house, and pick up that door to the "north" of the stairs (not shown, but labeled, top left) The stairs and kitchen are an exterior wall. No windows until you get to the kitchen sink. 3D Overview: That wall running through the refrigerator is the existing pantry area and would be beamed at about 9'. to match heights with the back room. The opening in the kitchen wall is new also--currently just two 30" doors on either end. It has a post in the middle due to a steam line that can't move. Plumbing in the back area does not need to stay. All can move. Current 6x9 bathroom is where the proposed laundry is, if that makes sense. Current wall location does not matter--it's already stripped and ready to pull. I just didn't feel 6' wide was enough for a laundry. The mudroom is basically the space that was left over after trying to accommodate both rear doors, and fit in the walk in pantry, laundry, and a half bath. All of those elements need to be in here in some respect. For scale, the entire house is almost 5000 square feet above grade. This 15.5x21.5 back room is just open, disorganized space (apart from the tiny 6x6 laundry).

Hmm. the first thing I notice is two doors opening into each other at the garage entrance. Frankly Im a bit confused on the whole layout 1. do you really need two dining room areas? 2. do you really need two bathrooms on the main floor? 3. is the entrance to the mudroom only through the garage? 4. you have teenage boys but a playroom? why is that not the workout/office? I would be using that dining space as the office workout room having the workout room where everybody has to passthrough to the to the house is going to be annoying. and also doesn't give you any privacy.
