Can your bath and closet be on the left end of the space and the bedroom in the space at the top of the stairs?

I agree to switch the location of your bedroom and bathroom in your mock-up.

I didn't really consider that option but yes it could be moved. I like that idea.

It was a conceptual and yes, I agree that I should consult with a professional. These comments about the bedroom layout help. The comment about the lower level plan is accurate.

For the bathroom, you want a toilet, shower and double sink - no tub?

Decide what sized bathroom and walk-in closet would satisfy your needs. Where are the windows?

In your mock-up where you have the walk-in shower, you can use that as a computer area, linen closet(if you don't put one inside the master), storage.

At the top of the stairs take about 3 feet and build a wall that will have double doors that open into the bedroom. You can bring the wall around to that space where the shower is in your mock-up - or not. As I said above, think about the size of the 2 spaces and what you need in them.

IMO you would walk into the bedroom part not into a bathroom wall then the space at the top of the stairs goes to exactly what the space is All the bathroom space should be where you have the bed that makes more sense to me.I would for sure want a large window on that wall with the view. For sure you don’t want a shower next to the staircase.anyway. We had the whole top floor of our house as a master suite but we had a small house so did bumpout for the bathroom

Thanks for the suggestions. I've incorporated those ideas in to this version - what do you think?

I think I'd make the office area a nice sized walk in closet. This way you get a roomier bedroom. Put a dresser under the window. You can add a pocket door to the toilet room with a window.

You need a minimum of 12 feet for a master bedroom bed wall. King bed plus 2 night stands.

Karenseb, I like that idea and thanks for providing the sketch. What are your thoughts on keeping the landing area as it was and moving the entrance door?

You will be covering up the 48x48 casement window - Karenseb, if you put the closet in that space.

There isn't an existing casement there. I'd have the option to keep the wall closed.

Do you need an office? Watching TV in bedroom?

Here are a couple more ideas after seeing your recent layout and request for a landing. I can see where you might need a landing to add a door to the bedroom.

I would have the door/walkway where I have it drawn (easier to get furniture into the bedroom. Larger closet.)

I rather like the first one that puts the bed facing the landing and close to the window which I would make as big as possible. Even as low and high as you can go! Then you can check out the view from the bed!

It sounds like a beautiful view.

I would do a water resistant window in the bathroom over the shower. Up high and wide and short. Do a pony wall between the toilet and vanity or you could enclose the shower and toilet area into it"s own room, but the vanity area would not have any natural light (unless the wall between is shortened, but it would still not be very bright) or you could use a skylight over the vanity.
