Dear, Client

Light is distributed throughout the room. There are two wall lamps and built-in lamps along the entire ceiling. Two built-in lamps are located above the desk. Also, around the false ceiling is set LED strip, due to better lighting effect. Desk with library is located in front of the window, because I wanted to take a maximum of that space and therefore the desk has a lot of natural light, as you wanted.
Furniture: The room is to small to set up a armchair, so that's way I set unusual designed chair, wich can be used as a armchair and as chair in the work space.
Air conditioning is moved, due false ceiling and the library. If you can't move, then the false ceiling and the library should be fit into whit air conditioning.
