You have very less chance to get into NITs with this rank. You may get NIT Hamirpur with this rank but again chance is very less. You should opt for private architecture colleges if you don't want to drop a year. Following are some of the best private architecture colleges of India.

1. KIIT Bhubaneshwar
2. HITS Chennai
3. SIST Chennai
4. Integral University, Lucknow
5. Manipal University Jaipur
6. Chandigarh University

All the best.
