This is in context to my Living Room for apt. which is technically one single large hall , But within this same space , we are looking to create three seperate spaces , i;e Main Living room , Dining Room & family living room. Is it advisable for me to go for elevated areas ,for each of the spaces. If yes , then I would like to go in the ascending order as stated , or maybe I should go for a single elevated area, which practically seperates the Main living from the other two. Also to note , that since its an apt. the ceiling height is not much. All the help appreciated!!

There are discrepancies between the two plans you have provided, so it is difficult to understand what has been built and what is proposed. That being said, the powder room will have more of an impact on the garage space than you are indicating, and think that will have negative impacts on the garage which you will want to avoid. The location by the dining room and stairs will also require significant changes to the plan in that area (powder room is still represented too small). The powder room adjacent to the pantry seems like a great place to put it, or in the ancillary seating space to the right of the main living seating. That seating area does not seem to have a great functional importance except to have the dining/living/side living space extend across the whole house, unless there is something happening that isn't apparent from the plan view alone.
