Hello Diksha, 

              After pursuing b. arch course one usually have a profession of architect. 

      Architecture is not only bound to just buildings, homes etc. It has a vast scope in government as well. Public welfare departments have architects to design bridges, flyovers and other structures. 

    Also it has a scope in private sector and can have a private business too.

GOOD LUCK
