Is it possible to start an architecture firm without an architecture degree?

No, you need to registered as an Architect with the council of Architecture which gives the registration only to people who have pursued B.Arch degree.

Hi Divya, No. You need to have a diploma in architecture at-least or a B. Arch degree or higher. Then you need to file a registration with COA to get a certificate of an official architect certificate. Then a service tax registration, company incorporation and other legal formalities. Hope this in
