So you like purple? Please buy soft lavender curtains, or some with purple printed flowers, I've had dark purple curtains in my old house (3meter high ceilings) and it looks really dark when they're closed. Add a purple sofa or lots of purple accents to keep it calm and friendly. You could paint the window wall a deep eggplant (not the other walls because of light) with creamy curtains.

Sand the down walls, and sheet rock the inset in the walls if you want to get rid of them (kind of reminds me of a bathroom). Then if you think the moldings have too much paint on them, then I suggest replacing them because it'd probably be too hard to sand off all that paint and it might look crappy painting over them.

You do have enough space for a small dining table , sofa and temple. You might want to section off your temple with a room divider . Here is a link to a page full of choices: http://www.wayfair.com/Room-Dividers-C416703.html Here are some small rooms that have both a seating area and a dining area. Hope they give you some ideas:

first of all, Thank you guys for those valuable inputs. yes, as far as cleaning goes, its just been finished installing and I have asked them to clean them up. And also, I observed that the frosting on the glass didn't look that good, so I am going for the filming on certain portions of the doors n windows. - Is there a particular quality of films that I may choose for this ? - Yes, lighting is definitely the criteria I had in mind which can bring up the finish to this. And i am worried about this , as I did not go for False Roofing, bcos the ceiling is already at a low height. I should really refine my ideas on the lighting part. - the stairs are floored with white Marble stone..My mom loves it and the matting on it might hinder its beauty, but yes I will surely consider that as well. Thank you again.
