Most my doors were already here, but I did have one moved over, about 6 inches. However, the entire space was demo'd, and rebuilt, so that's not the best example to draw from. If you want the door hidden, in a pocket, yes, you will need a skilled carpenter. Essentially, the opening header and frame, will become twice it's size, with the "pocket" part, hidden behind the wall. The studs/supports will need to be removed to make a space for the door to slide into. Do you have any switches or outlets on the fireplace wall?

Mohammad. I understand your program. You may be lost in the details at the moment. Please do follow and trust the advice given here by all these people. You are about to embark on a reasonably expensive journey. Get professional help with someone who you can sit down at a table and brainstorm with them your ideas and intentions. There are Architects and there are professional building designers who are members of the American Institute of Building Design (AIBD) who are well versed in projects such as yours. I personally love a design challenge. After 38 years designing homes and special use buildings I enjoy this type of challenge the most. I am in Ohio and may not be close to where you are but I am sure with a little investigation you will find the best design professional for you.

For the living room, the focus should be the balcony area. So flipping the couch to face the wall and not the dining table will help. Kind of like this pic. Even if you already have the sectional that is in the diagram, you should be able to flip it. In fact a sectional would probably work better than the couch in this pic. I also really don't like the style of this pic, but it showed what I meant, For the girls' room: No matter which bedroom you choose, you should maximize floor space so that they have the biggest play space possible in their room (as they get older you can add desks for school work and such). To get this space, I would give them bunk beds. This configuration gives them an open feel and more storage, essential for girls. You posted two different kitchen designs. This makes it hard to give you advice. I agree with other posts that your sink should be away from the wall. This allows you to have stuff to the left of you (drying dishes in my house), while you wash vegetables on the right of the sink. You need the same space on both sides of the stove, also. At least 24 inches on both sides is good. 36 is better, though. The first design has a nice little countertop space that adds a place for your daughters a space to sit a watch/ talk to you while you're in the kitchen. When they added this to the first design, you lost cabinets on the other wall. This is bad, as the space is already storage limited. Try making the rounded countertop bump out into the living space more. If you play with the shape, you could make it work without losing the cabinets on the other side. It doesn't have to be rectangular or a perfect circle. You can see how this one isn't confined to the floor plan of the kitchen. I think this is what you would need to do to make it the most functional.

Debbie, acm - Thank you very much for responding. This is a new apartment and not a remodel. I have attached the floor plan of the room & closet. In the photo below the closet is the space "DRESS" and having dimensions 5 ft 11" (X axis) x 4 ft 7" (Y axis). For representational purposes, the diagram shows an L shaped closet. Ignore that - this is a complete blank space. I am instead planning on putting the closet along the 5 ft 11" wall- but on the opposite side instead of the side shown in the diagram. So imagine my closet along a single wall, set against the wall marked with a thick dark line. acm - I did not mean a bi-fold. But rather the traditional shutter door which some may refer as a swing shutter. My dilemma is - should i use sliding doors or regular doors ? I divided my closet into 4 major compartments, each 1 ft 6" wide. So there are a total of 4 doors. Depth of closet is 2 ft. Hence walkthru space is 2 ft 6". When a closet door is open, there wld be 1 ft space between the open door & the wall. Within each of these 4 compartments, I have designed multiple external drawers upto 2 ft height from base. So the shutters/doors planned only for the portion above 2 ft. Sliding Doors - Pros - Swing space not needed. Can place a slim dresser in the corner if I want to later. Cons - Expensive as it will needlessly cover the bottom-most drawers; Sliding doors coming off rails. Regular Doors Pros - Inexpensive. Can be used to cover only the part above the drawers (need not cover drawers). This way I can open the drawers below quickly & easily. Cons - Not sure if 2 ft 6" is enough clearance space to open 18" doors. Hope this makes sense. What do you suggest?
