From your idea book, I see you like very modern houses. Is this going to be built in India? I found a one floor layout that might work for you and you could do the exterior to your taste. But I have to say, you should look for professional help in India. I imangine code requirements and material are much different there. Search the internet for modern and contemporay house plans. On site I found was this and here are some houses that might fit your land. http://www.theplancollection.com/house-plans/width-25-30/depth-40-50/contemporary/modern/single+story/two+story/three+story/split+level/ As I said before the exteriors can be modified to suit your tastes. Good luck.

you can share the pictures of current construction and if possible layout plans, then only we can suggest a design for you.

all seems great.. no need to modify,

I feel partitions are not needed. You already have too much for the space. Adding a partition will shrink the space further. The simplistic solution, you do not wish to discard any furniture would be to paint all the walls in lighter pastles. And use some wall painting frames to highlight certain walls.
