Hi Manjunath
1. Ground & second floor most changes are same as first floor. Its typical & same grid plan, except hall is divided in to two parts.
2. Any floor plan while designing basic furniture should always be shown and only then window, door locations can be finalized
3. Just by room size one should not consider it is well placed or designed .
4. Its important to see what is out side to your bedroom, living, kitchen windows. You might be facing neighbour toilet vent next to bedroom if you go by vastu in most cases.
5. Your SW side will be NW for the neighbour and he has all liberty to place a toilet
.
6. While planning you need to look for internal & external factors too.
You should ask your architect to rework on the plan showing the entire furniture in actual sizes that you wanted to accomodate in your home.
Attached the image to show changes in the second floor.
All the best for your construction .
