Is this built and you need furniture ideas, or do you have questions about the plan?

I think it totally depends on two things, 1 The available space 2 Your religious belief. Someone who is very religious may try to squeeze a separate space even in tiny flat, while someone who is not overtly religious may just have a small corner with Idols in spite of being in a position to have a separate room.

Ideally pooja should be next to kitchen which is also preferred by most in AP & Bangalore. As per Vasu it should be in East or NorthEast of the flat area & while you pray you should face towards East. occupying foyer area is good but need to divert the flow to avoid walking with footwear in front of pooja room, so need to change the entry which I think difficult from Prestige as they wouldn't accept that change The other option is at Wash Basin However you should hire a professional so that you get right & full guidance. If you've already hired then you can demand to fulfill this requirement as well.

First of all I think you should better take off that sofa covering(the floral one) off!!! There's already soo much of texture and variations that it's all looking cluttered at one place! You can go for a tone of beige lighter than that of your sofa with textured effect wall paint and couple it with a nice large sober painting. See if there's a provision for adding a spot light over it as well (on the ceiling).
