Not too sure ab out the exact question. but I will tell you that 1000 SQ FT is really small and usually could do one bathroom and two bedrooms without a formal area for living space and eating space in the kitchen.

You need an architect

U will have to modify whole design. If not, You may look into few following suggestions- 1. Comparatively Living room size seems to be smaller . 2.powder rm- better to have it near dining / easily accessible from dining space. 3. Family n dining space is big enough but not utilized properly. 4. Toilet layout could be improvised. Yes as per vastu u need to change some things-- 1. SW corner should have closet space ( meant have storage) 2. SW corner should not grow .instead NE corner should be growing. 3.SE corner to have cooking area not utility. Hoping this will help u in improvising the design.
