Every body is different. Measure your leg from hip to knee, while in a sitting position. Add the number of inches in the depth of the back cushion to determine what a comfortable seat depth would be for you.

I'd suggest dark red curtains if you need curtains at all -- the windows are beautiful as they are, and I'm not sure whether some kind of blind might not give you the ability to darken the room when you want to. On the wall, if you are real fans of any movies or TV shows, three big posters would be fun. Otherwise, I would still suggest using three pieces of art there of that size, all equal in size and somehow relating to each other. Three floral works, or three works in the same style, perhaps. I think a large plain textured rug in a light neutral from one of the cushion fabrics would tie the space together well. You might also consider a lovely low coffee table on the rug to lay out your snacks and drinks for serious media nights.

Hello Bikash, 5x3 pooja room is not a big one. However, it will be a good idea to do the civil changes you mentioned.You will get additional space that ways . What do you plan to do with that new space. We see a beam in that area, keep that in mind before you proceed with the changes. Wall mounted pooja unit is doable in multiple areas as per the plan. Do you have the directions mentioned in the floor plan to suggest it as per Vaastu. Thanks Nitin Cornerstone Designs Bangalore.

Zubin, This depends on the municipality you are located in. You will have to adhere to setback/ FSI standards there in. It is ideal to contact a location expert. Thanks, Nitin Cornerstone Designs, Bangalore.
