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.

I have not specifically looked for modern, but you can try houseplans.com and you can filter your search. Also try a google search for contemporary house plans. I am sure there are multiple sites out there.

@soberg: on the toilet entry we thought we could have a 2 way access to the corner most toilet - one from the closet side and another from bedroom 3. @ eagledzines. Thank you for the sketches! On the high ceiling do you think we could juggle the entire layout of 1st floor a bit to accomodate a small family room (hall) where the staircase opens along with 2 other bedrooms. We are ok to compromise on the room sizes a bit and toilet / closet positions can be changed too as long as pillars are not affected.. The kitchen changes sound good. I was also wondering if it would be ok to have the sink right below the window. Thereby freeing up more cooking or prep space.

@BeverlyFLADeziner: No, I'm not assuming the back has a finish. If you are referring to the cable being visible, or the approach to route it under the sofa would not work, there are two options: Align the table so that the "backless" back is up against the side of the sofa. So, flip it 90deg compared to the image of a sample sofa and this table posted earlier. The cable can be stuck along the curved edge of the table on the back, so that it is not visible. This way, it gets down to the floor along a surface that people cannot see as opposed to dangling through the hollow portion of the table.
