Please help re-order house

2) North west and south east is the best for kitchen. 
3) toilet west or north west

4) kitchen and bathroom should not share adjacent wall

5) daughter bedroom in north

6) boys bedroom in east

7) master bedroom should be in southern area

8)  Temple should be in north east.

Actually there will be lot of changes if you change this house. 

Each room is built against vastu . It will be better if your hire some expert who could help you with  remedies for few things and easy changes can be done. 

But drastic destruction is not beneficial. If you would like 100% vastu compliant home then you should demolish and construct a new one. 

some changes i think can be made as shuffling the rooms 

Eg sons room can be shifted to the south east and parents to the south west and daughters to the north west 

will that do any better 

i was also wondering i wanted to shift the pooja room to the north east as recommended but my main problem is that my house entrance is in the north side of my house and facing the east so if i place the pooja room there will it be ok infront of the entrance

or else mayb i can create a wooden partition and make a small pooja room on the northeast corner of the house 

please give me some advice 

thanks
