Hii satish,

If your rank is in top 500 then you can easily get an architecture seat in top NITs. like SPA Delhi,NIT Trichy.

The cutoff for B.Arch courses is about 50% of the total marks.

If you're above 70% then you can get a seat in one of the finest institutions in India offering B.Arch.

The Opening rank for SPA New Delhi was 98 and it closed at 798. For candidates that did not have any state quota the closing rank was 827 in NIT Tiruchirappalli and 2377 in NIT Patna.

ALL THE BEST!!
