Who are you trying to contact ?

I have tried to enlarge your plans but they become to blurry to read.....Is there anyway that you can post a larger jpeg?

can you suggest how can designs my rooms

First you need to get a bigger T.V and some surround sound equipment , a cabinet to house all the wires parts etc., blackout blinds for the windows and some comfy seating for at least as many people as you have living there. This will never be an actual home theatre as you can not close it completely but it can be quite good with some imagination.
