I found more convenient to propose a vertical FanCoil instead the horizontal, it helps with the lines of the environment and allows a not so symmetrical game in the rockwall furniture.
Coating the column with mirror will integrate it while expanding the visuals
The proposed solution for the entrance door is to hierarchize it by a small wall painted in a color according to the upholstery of the sofa
Finally the isolation of the kitchen is solved with a sliding glass wall door
