likithraaj, OMG - serious? You really need to sit down and do up a proper floor plan complete with where plumbing, electrical, hvac etc., etc. are going to run. I can't believe you've demolished your home before having a proper floor plan! Hire a local professional interior designer to come out and get that portion done right - and, to anyone else out there - GET YOUR DESIGN ON PAPER FIRST BEFORE YOU DEMOLISH. It is so much easier to change things and not be pressured into making last minute decisions. likithraaj, your going to have to make some quick decisions - ones that I'm not prepared to assist you with at this juncture until a proper floor plan has been submitted. Good luck - and forward a floor plan.

loft will be 5 deep and 3 feet from the ceiling it will have a water tank and I can keep other stuff.

I like what you did on the previous TV wall, a lot. Now I suggest, let that be the only piece of bright colour in your space, and pull designs for cushions from there. I suggest colour rest of the walls (+Doors on the side facing the room) in a neutral, warm white, matte finish color. The wall behind the blue sofa, is it tile? Can it be coloured over? Also, are you in a rented space or is it your own house? That would help understand if you can make semi permanent changes.

Ravi, Are you planning just a small room or would you have a pooja cabinet as well in the room. You may need more space for a seated pooja arrangement and often you have multiple people while pooja. Decimal measures are just fine no such constraints that I am aware of. Thanks, Nitin. Cornerstone Designs, Bangalore.
