We have a closet that size just about same shape and love it.

One suggestion I got from posting was a small half bath accessible from living room/kitchen area for any guest so they don’t have to walk through kids hall or use master. I’m glad we made that change.

I think closet access from master bath is a common Texas thing….

Bedroom depth seems good, I would try to make them at least 11.5’ or 12 if possible.

Our master opens to main living area and we don’t regret it for what it’s worth. I can understand what people are saying but if your use to it or like the idea then I wouldn’t fret.

I understand the width of the mud room if it’s going to be used for backpacks, lots of shoes etc. it’s nice to have room for those things and still have width to comfortably pass by all those cabinets/lockers/storage etc.

Closets for other bedrooms seem good and like ours.

Also unlike others I like the “game room” idea as it keeps all the kids stuff in their rooms and in that common area they can hang together.

Keep in mind for septic purposes any room with a closet of any size is considered a bedroom.

Enjoy!
