Thanks! I knew I should have posted more info! I started a post with more but pared my question down.

Hopefully that comes though ok. It gives a rough idea of the unit but the actual build out was customized quite a bit from the original plans. The circles are concrete posts. The blue box on top is the kitchen. The blue wall is the existing wall. The red walls are the planned walls.

Goals of the project:

-- Build 2nd bedroom.

-- Add 2nd closet to master suite.

With the plan above the master ends up being 15'5"x 13'

So the only way to increase the bedroom size is to take space from the master/new walk in closet and scrap the 2nd master bedroom walk-in or to jut the wall around the post and steal space from the dining area (which is huge, but to me encroaching the wall further into the living space is awkward.)

At the end of the day I think I'm comfortable with the 11x11 bedroom. Kid one is an infant and kid two does not exist yet. But we do want the unit to work for another 5-7 years.

Thanks again for your response!

And, the dining room is between the 2 circles/poles to the right of the new proposed bedroom layout?

I actually think I'd do a couple different things than you are proposing. Here are my thoughts.

I'd build the kid room wall to be even with the kitchen wall, which I think puts it around the other post. Yes? If not, then build it through the post, which seems to be what your corner posts do (walls are built around them).

I'd put the bedroom door nearer your master, rather than nearer the kitchen. It lends more privacy to the second bedroom. I know you said they are small/nonexistent now, but they will grow bigger. And, will you live here forever?

Does the second master closet need to be that large? The first master closet appears to be quite large (including the hall space between it and the bathroom, it actually takes up about as much space as what you are proposing for floor space in the kid bedroom).

OR--Would you consider any of these options:

1) Make your current master closet narrower, so you could have a 2nd master closet system (reach in, or like what you are proposing for bedroom 2) facing your bedroom, along its wall? It appears there is a lot of wasted floor space in the master closet currently.

2) If you do not choose 1 above, making your 2nd master closet, as drawn, but less deep--so you could have the kids' closet facing their room using part of that space?

OR-

taking that 2nd closet space and extending the walls vertically (in the drawing) the full length from hall to outside wall, including the area of the post; then splitting the closet into 2 walk ins--a 2nd one for the master, and a primary one for the kids' bedroom? Presumably, the kids' room closet would get the post.

OR-

Same as above, except split it into 2 reachins--one for your room, one for the kids' room.

Thanks again for taking your time on this.

Extending the wall out to line up with the kitchen adds another 3'5" to the room. I've considered this. It would look about like this:

My hesitation is what it does to the dining space. I've actually set up my sideboard/dining table as if there was a wall there and it just messes with things enough for me to not love it. It causes the dining table to be pushed towards the living area so it no longer lines up with the middle of the kitchen/ island and it cramps the space a bit horizontally (in the floor plan photo) which feels weird since there is so much space vertically. At the end of the day I'm sure it would be fine but maybe there is a better option.

The bedroom door I put on the closet side because I thought it would mess with potential furniture placement too much if placed on the master side. I also have considered putting a door at the end of the new hallway to separate the bedrooms from the rest of the unit, but I think that might be odd since the 2nd bathroom/powder room is within that space.

This is not a forever home for us I'd be shocked if we still lived here in 10 years.

The second master as drawn is about the minimum width I would want for a walk in. It's 6'2" wide which for me is good for a hanging on one side and shelving/some drawers on the other side.

Putting a reach in closet for the kids in the space I have allocated for the 2nd master closet is an option. But it seems to limit our options for more master bedroom closet space in ways that I do not really like. The first master is 7'2" x 8'8". So not really enough width to do as you suggested. We could put a 7' wall of wardrobes on the current wall just outside the closet but won't that look bad when entering the room? Alternatively, as you say, if we split the proposed master into a kids closet and a master closet (or wardrobes), the master side will be facing the foot of the bed, which I don't love in general + we do watch the tv some in bed and it makes that quite awkward.

I don't think the dual walk in closet option is doable. There just isn't enough space.

I guess we need to figure out what compromise is the best for us. I had thought the smaller bedroom would be fine but thank you for making me really analyze it.

Ok, so I think this the the best alternative concept:

In this layout, Kids room is 13'7"x11', Kids Walk in is 7'3"x4', the master gets an 11' long space for a built in wardrobe. in which we either integrate a television or just scrap the bedroom tv altogether. Seems like when it comes down to it this is a better use of space.

Yes. Though my additional comment would be: what is gained by having a 4' wide walkin? Usually, you'll have a hanging rail along the back (the length of 7'3"); and then you have 2 feet of unused space in front of it.

Instead, I think it is a much better use of space, if you don't have at least 6' of space for a walk in's depth, to do wardrobes, or reach in closet.

Something to consider.

Thanks kirkhall. Sorry if it isn't clear, but the kids room walk-in would be 4' deep and 7'3" wide. So 4' of hanging space on each side and maybe some shelving on the back wall. I'd like to do the wardrobe on the master side the full 11' width so this is what the result is.

So Thanks again kirkhall for your help on this. It has fittingly come full circle where my question now fits exactly with the thread title. Here is the current plan we are moving forward with. Yellow walls are new construction.

Does anyone see a better way to do the doors? I am trying to avoid the doors opening into each other. This plan does that but uses 28" closet and 32" bedroom doors. The rest of the unit has 34" doors. Thanks!

Using a pocket door for the closet would solve this, wouldn't it?

Pocket, bifold, or pivot swing doors on the closet would all avoid door conflict. You could probably even be fancy and do a double sliding closet barn door (I've seen some online where someone made up a mechanism that slides them simultaneously the opposite directions).
