You have 2 living spaces already so I don't see the point of spending big $$$$ to make one a little bigger, make the powder bath crazy small, and the laundry room dreary to be in.

edit - I'm sorry my comment came out a little rude! I really like your 2 living spaces and would be happy to just move in for now. Live in the house a little before deciding to make changes.

Are you living in the house now?

for me shrinking the laundry room to slightly enlarge the family room wouldn’t be worth it - but moving the laundry upstairs would likely be a big improvement so I would likely focus on whether that could be done - if not, I’d leave things alone

I happen to love my main floor laundry and never go back to running up and down stairs to do laundry . I do agree not worth the money to enlage the space toy have Usually I lkke the FP in the LR and the TV in the FR but you have what appears to be both in the FR so IMO what you have is good and for sure not worth changing when you have not even lived there yet . I would spand my money on the kitchen that angled island would make me crazy and no access from the gargae to the kichen without a maze those IMO are more important than the size of the TV room

I wouldnt enlarge the family room, at the expense of making the other rooms, way too small. Since you already have a living room, the family room is fine the size that it is. I too, would leave the house just the way it is, and not remove any walls.

Thank you for all the inputs! I really appreciate your comments. Personally I still like the idea of having 2 feet added to the family room. But I don’t know if 4 feet wide mudroom (or laundry if I don’t move it upstairs) will work. Is 4 feet wide mudroom just non-sense?

Why not mock it up? hang a tarp or sheet up to mimic the new size and see what you think - is there are any electrical or HVAC in the wall you want to move?
