Do you mean a shrine? Can you post a picture or two of what is there now?

can i have few designs to design a temple area in the corner of a drawing hall

It looks like a small room to me. I cant suggest a placement plan with knowing the plan. But some tips I guess may work for the corner. 1 . Use no temple. 2, use Dias and Mirror 90' Degree on the walls. to reflect idol in the mirror. 3, Many small one medium size Idol is better than too large one or two many small ones. 4. Use glass temple . 5. Make hanging temple if cant change the corner. 5. Don't use anything over and under as storage.

I want to decorate wall behind the sofa with temple in one side, pls suggest with good design
