I thought the same thing as Virgil on the hallway, but having a desk there by the window near the bedroom at the front of the house makes sense. Instead of placing a new piece of storage furniture in that hallway like you mentioned, I'd build a storage closet that would open into the hallway. (Right beside the closet in the bedroom in the front of the house.) That's wasted space anyway. And you could store office-type stuff in there since it would be close to the desk. Or you could do open bookshelves instead. I'm not sure the expense of moving the doorway of the existing bedroom is justifiable. Unless the door is in the way of the laundry closet across the hall. Other than that, I like it.

Have you done anything yet? Just some thoughts: You might consider turning your master bedroom into your living room space. (One option if you do: you could enlarge that space by enclosing part of the front porch and moving the existing front exterior wall outward, creating a front entry and giving you the option to add a door to the front right corner of the garage to access that entry.) You'll want to wall off what is now the master bathroom from what is now the master bedroom so you're not looking into a bathroom from your new living room. Alter what is now the master bath and shower/laundry room. You want to separate the shower room and any/all parts of the bath from the laundry. You need to move the bathroom vanity from its current location so it is set across from the toilet, creating a "powder room". You'll want to leave the shower approximately where it now is but flip it -- you'll want to access it from the other side through what is now the back wall of the house. You'll want to create a hallway from what is now likely the dining area (behind the kitchen) that will pass by and give you access to the washer/dryer ... a hallway that leads to the door to access the garage. The back wall of that hallway, which could be shallow floor to ceiling cabinets, could be placed approximately just above where the words "master bathroom" are on your sketch and have it extend in a straight line to wall off the (flipped) shower from the new hallway. With the back wall to that hallway walling off the shower and the toilet and the vanity from the washer/dryer side of the hallway -- you'd then need to remove parts of the back wall of the house to enable access to your new master bathroom with its shower and toilet and vanity from the new master bedroom to be built behind the new master bath. The first several feet of your new build behind your house would be the foot traffic part of your new master bath with a window at the end of that ... window facing the left side of the house. Build your new master bedroom behind your reversed access master bath and have it accessible from what is now a back door across from the door of that front room (formerly master bedroom, now living room). What now appears to be both your living and dining room will become your dining room -- with your dining table by the patio doors and a china cabinet on the right end of that room. You could add a closet or pantry or desk on the left end of what now appears to be your living/dining in that space just left of what is now the back door ... with that back door becoming the access point for the new master bedroom suite. You'd have the option to leave the washer/dryer open and visible from that new hallway or enclosing it in a closet. You'd have the option to make that back wall of the hallway floor to ceiling shallow cabinets -- with or without a hall door to access the master bath so that it could also be used as a guest powder room without guests needing to access the master bedroom to use the powder room. (perhaps by enclosing the washer and dryer in a closet or at least flanking them on each side with a narrow floor to ceiling cabinets while creating a hallway that will provide access to the washer/dryer and to the garage just beyond that.

I feel like this is spam. Anyway, the thing that sticks out in the middle looks like the original house(?) and then turning it into the "modern farmhouse" by sticking more square footage on either side...trying to sort of get it symmetrical. It would be a lot more interesting if the owners were posting and asking for advice. I wonder why the backside of the house has few to no windows. I'd like to see my backyard from the house.

Unfortunately, most of the builders have pretty similar plans...and the only builder that had the kitchen against 2 exterior walls (still only windows on 1 wall) was also a smaller house that the builder refused to move exterior walls because they were so busy. The only builders really open to complete customization are also extremely expensive and require either reducing square footage or putting the house at the very top price of the neighborhood. I made a quick attempt at moving the kitchen to the back corner of the house...I agree with swapping the laundry and powder bath, and am still attempting to convince my wife of the same. I'm not sure if the builder would even agree to this large of a change. Thanks again for everyones help!
