Move Living Room in front
Can’t you just flip the uses? Rooms seem similar in size, except the existing Lounge has a lot of circulation and the existing Drawing Room can be private. 

Otherwise, a major remodel might be to switch the kitchen with the Lounge. Put the Lounge in the back with the bedrooms and add a large curved island bar (with barstools) in the center “domed” area. 

In my house, everyone gathers around the bar area. 

BTW, do you have a refrigerator?
