Hello Tejugowda. Thanks for contacting Careers360 and we hope we will be able to answer your query. 

I have to first admit that your question is very broad. In the sense, that how do you define "famous"? 

What, according to you, makes an architect famous? Anyways, I would advise you to Google search: "famous architects".

These links from the Google search may help you a lot:

Also don't forget B.V. Doshi, this year's Pritzker Prize winner from India. See here for more information:

Hope this helps you and all the best!
