Unless the owner or the landlord permits it normally you can not make any permanent structural changes. A drop ceiling would be that. What is the issue with the current ceiling?

Kanupriya, Well when you say 'it can be touched' I hope your don't mean you are going to let such a sober place be taken over by this piece. I would recommend you suggest vinyl stickering to your clients (for center 4 shutters at least). That should leave the client with a flexibility of removing the vinyl when they want to. You can take the cues from the color splash and decorate appropriately. Thanks Nitin Cornerstone Designs, Bangalore.

Ok there is a lot that you can do to decorate this place. You can put nice white/cream curtains along with white/cream curtains so that you can use net curtains one when you want more light. You can place a small decorative plant on that window. Another thing is that you can do is cover the wash-basin pipe. You can use a couple of small frames to hang on the wall that compliments the color of the wall. Talk to top interior designers such as Tasko.
