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.

Thanks. The ceiling height is 9'6". Suspended ceiling preferably made with POP placed in situ shall result in a plenum of not less than 15" considering an acceptable height of about 8' at bottom of ceiling from floor level. Two ceiling fans of sweep 48" each placed at first and third middle quarter also needs to be integrated with ceiling profile. Will send ceiling and all around room pictures shortly after compiling. Thanks again.

The energy efficient bulbs shown in the above photo suck the light is awful and they butn out quite often, if you want real energy savings go with LEDs they come in warm or cool light and you probably never have to chang a bulb as long as you live. They come in all kinds of wattages and can be retrofitted in almost any fixture.

Ground VAV Fan Powered Terminal Feature Description: 1) FH-VAV-GFP ground series fans terminal is a set of removable underfloor air supply device. The outlet and secondary air return consist of two grills with inclination. 2) The first air is supplied via underfloor air supply system, pressure independent control. The fan runs in fixed air volume to induced some inner secondary airflow. 3) Using High precision flow sensor with FH-001 patent, it can increase the flow gain coefficient 1.2~1.5 times and accurately measure the air speed of 1m/s or above. 4) Using centrifugal machine with low noise, it can realise 3 speed adjustments. 5) 500W and 1000W type heaters are available for options. 6) With DDC controller, it can be connected with BA system via standard LON-works, BAC-net or other communication protocols. 7) There are scale, LED and digital display panels for user's options. 8) Basic Technical Assurance: A) The air speed for where 0.3m from the air outlet is not exceeding 0.5m/s. B) The inner temperature gradient is not exceeding 1C/m. C) The inner noise level is not exceeding dB(A)40. D) Ensure to meet new air requirement through setting the minimal air volume. Controlling Scheme Description: 1) Ground series fan powered terminal is connected with the central air handling unit (AHU). We suggest to interlock the terminal with AHU directly through an air flow switch. And the switch can detect the pressure of the first air inlet. 2) When the inner temperature goes higher, the controller will release the signal to increase the first air volume. When the first air increases, the secondary air will decrease accordingly. and the fan will run in fixed air volume. When inner temperature exceeds the set point, the first air will keep at the max volume. 3) When inner temperature drops, the controller will control to decrease the first air volume. 4) When the inner temperature reaches the set point and first air reaches its minimum, the fan will begin for the secondary air supply. 5) When it decreases constantly in inner temperature, it can start the heating coil in grading.
