Hi Sudhir,

You have not mentioned the college name for which you are enquiring about the fees of B.Arch by NATA.

If you are asking generally, than the course fees of a government college for B.Arch course by NATA is about INR 60,000 to INR 90,000.

Refer here for the list of govt. colleges accepting NATA - https://engineering.careers360.com/colleges/list-of-government-engineering-colleges-in-india-accepting-nata

I hope this information helps you.

Good Luck!
