Bump.

OP maybe if you take a stab at it yourself, you'll get more responses and guidance. Without detailed info to go on, commenters can go in a hundred directions. Like is "Master Bedroom" size of 12'x15' good enough, or you must have 18'x22'? A closet island? Laundry require lots of folding counter? Access to main house is through Kitchen? Building details like plumbing an old garage slab. If you have a sketch, some of your wants get translated in what you have layed out and then can be questioned or run with.

We pretty much are starting new - the roof and two walls are the only things staying. New slab/ electrical/ plumbing/ etc. Just using the same footprint because it makes more sense with the existing house. I edited the post to give more info - thanks for the helpful comments!

Where is the door by the laundry go to in the first one? Do you have a powder room (half bath) in the other part of the house? This one doesn't seem accessible for guests without walking through the nursery.

Where does the connection to the main house dump you? In the middle of the kitchen or to the side of it or??? Can the connection move up/down some?

What size beds do you want to be able to fit in the master and in the other bedroom (nursery). Will the latter hold someone besides a toddler at some point?

Good start. Same questions as lyfia has, would the Powder be better accessible to the main house, do you want access at the back, what is the front french doors accessing (utilized by rest of house or better for just Master?), opening up Kitchen or even extending it somewhat into this space.

The door by the laundry in the first one would lead to a small courtyard in our side yard. We don’t need access to it but it’s kind of unused side yard space otherwise, so we could link to it and turn it into a nicer area.

We do have a powder room in the other part of the house but it would be nice if this one could also be accessed by the main area (doesn’t need to be in the nursery). We have a king size bed, and ideally the nursery could eventually hold at least a full size bed if needed. The French doors lead to our backyard and we want them to be accessible without being in the master. The connection to the house is on the side of the kitchen by the pantry. It could potentially move east (up in the picture) but we’d have to reconfigure the pantry and a closet in the existing house. I’ll draw up another picture that shows what’s inside when I get back from vacation next weekend. Thank you for your help!
