One possibility would be to swap the living room and the dining room. Since the current living room is larger than the current dining room you could still keep some comfortable seating (couch and upholstered chairs?) against the front wall for a keeping room/dining concept. Then your new dining areas (kitchen and dining room) and living areas (living and drawing room) would have good flow between them, which would work well both for family and entertaining. You could also add some builtin bookshelves in the drawing room or new living room to create a library area to add another fun element to the living areas. These bookshelves could be against the long walls in the drawing room, around the window with a window seat in the living room (former dining room), or built to create some separation in the open area between the drawing room and living room/stair area. Your plan seems to show some sort of builtin there, but I'm not sure what it is.

go to a lighting show room, take pictures of the space and any ideas you have. They are best suited to help you. also have a budget. the how to part is nice but most consumers have no idea that the pendants above are probably 300.00 each. Budget for lighting! take advantage of the pro's in the lighting world, its all we do!

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.

To make space for 3 study tables including your wife's, you must get rid of the steel almirah. Have an extended open wall shelf of 3 rows for books & storage & 2 spaces next to each other for desktop/laptop where there is currently one. The right side wall near the small kids table can be made into soft board for ideas etc and then have the marker board next to it. Above this table can be small open squares for toys/books etc. Use eco blinds instead of curtains to regulate light & cool the room if you want to make the space serious. Remove the clutter under AC and have cushions/fabric seater to make it a lounge area instead. Use mutiplugs or extn wires to reduce wiring. You may consider a good quality designer fan with pendant LED light which will amplify lighting and ensure silent reading or studying. Else, use an effective LED tube on both sides with a blue themed fan.
