At first I thought to extend the center wall to about 3 or 4 feet from the window, but that will give you only about 2' to walk past the bed to the closet and bath.

My son used a folding room divider to separate his studio apartment, it meant could flex it a bit to suit the space and his needs. So I suggest you consider a folding room divider.

The challenge is of course the window, and where to put the entrace. If you enter the bedroom through the end near your windows, then in order to go from the kitchen to the bathroom, it is a long walk around. Does that matter to you?

Do you own and are you building something permanent? Do you live in NYC or another city with companies that install temporary walls?

If you are making a dedicated bedroom, do you need a murphy bed? I'm not a fan of them.

I have seen a lot of Parisian studios with lovely glass walls.

It’s not a primary home , I am
Using it only occasionally. I like the glass door sliding idea as it will not block the light coming into the room.
Do you think a shoji style door would be ok. I am also thinking of entrances to the room. Should it be in the center of the room or opening to one side .. its doesn’t matter which side to me honestly .

What is the purpose of the wall? Are there 2 occupants and you need some sound buffering between spaces when one is sleeping and the other is not? If that is not the case - why not float a ‘wall’ of open back book shelves between the sleeping and living spaces? It would give a sense of privacy/separation and offer storage opportunities and yet still have some light filtering. It could be designed floor to ceiling for stability.

I fear that your heating and cooling would be compromised if you separate the spaces with a true wall system.

Purpose of wall is to create a separation and use it as a junior 1 bed if i have to entertain over night guests . I would like some privacy. Good point on the heating and cooling .

The reality of your space is that a guest would have to walk into your bedroom to use the bathroom in the middle of the night.

If you own the unit you may want to create a new entrance to the bathroom rather than through the bedroom. A dividing wall with a door-less entrance to the bedroom near the window. Here is a simply idea but unsure if the space will be what you would like. The wall will need to go into the living room some so you have at least 3ft at the foot of the bed walking space.

And, have you asked the building if this type of modification would be allowed? Do you have a smoke alarm in both main spaces? My guess is that a separating wall would not be allowed.

That’s a creative suggestion Lorraine but wouldn’t you say that day to day use of the bathroom / bedroom relationship not to mention lost storage would be an issue?

Thinkdesignlive The OP states it is an second home occasionally used and when I did a line measure the new closet is a touch larger than the old two closets combined but there is a loss of floor space in the new hallway.

I see no big issue here a guest can use a sofa bed in tjhe LR but the entry to the bathroom is a bigger issue that is puzzle and needs to be addressed first
