Hi Athira,

What i understand from your question is that you want to change your field of work from Engineering to Architecture. I don't think age should be a problem for you as you must not be under age for NATA and other B Arch exams. Well technically there is no upper limit for B Arch just a lower limit which is 16 years and above. So you should take up the entrance exams like NATA and JEE Mains 2 and apply for colleges.

Good Luck !!
