Not much to go on. A drawing/floor plan to show where windows, doors, and such are in the space... and what connects to this space? You say first floor, so where are the stairs? Two rooms... what are each of the rooms to be used for? (Kitchen, living room, dining room, a bedroom, an office.... what?)

I had purchased hafele hob 10 months back... I got it serviced 6 times... Now i requested for replacement with new one... Still they have not attended my request...

this is not a plan Rohit ji it is just a drawing. whom so ever have proposed you this plan he just have drafted some line none of architecture rules followed none of the scientific architecture vastu is been applied. it's just placement of squares and rectangles here and there.

I dont think u can use this golden laminate sheet on gypsum ceiling , i m not a expert though. In the ceiling of one of the room i have used mdf sheet and used the same golden laminate to highlight the border.
