Thanks to give me opportunity to design your office.
I didn't change your wall ceiling or floor texture or color as you said so i placed wooden strip design on wall to add some look in it & i placed a ottoman & a chair for your relaxation & placed a TV for your video watching & i gave a U shape workstation for your 4 monitors & i placed the monitor as you can show these monitor to your client without any trouble & if you want anything else please free.
