Everybody hear will make u a descent plan but my plan would include :
1. a 3d modeled plan with soft render
2. according to vastu sashtra or not (i am flexible with both but i prefer vastu)
3. Duplex plan with mandir, 2 bed room, hall , kitchen strictly according to modular fitting ,attach bathroom and common bathroom with faucets and vanity fitting placement
4. wardrobe placement plan (fixed furniture plan ) in bed rooms
normally a 3d model will cost u 15-20 K but it would be less hassle for me because I am already working on similar projects , that's why I would be your pocket friendly.
