Hello dear, 

Yes, the diploma in architecture is available. 

It is a certificate level course in the domain of Architectural engineering and its related areas. The course can be pursued by candidates after completion of their class 10th education. The course is of three years duration with a semester-wise system of examination.

Admission to the course is done mostly on merit basis that is the percentage of marks obtained by the candidate in class 10th board examinations. Colleges/Institutes offering the course demand a minimum of 55% marks (Relaxable for reserved category candidates) at 10th level with Science and Mathematics as a subject of study in order to get admissions in the course.

Hope this helped. 

Good luck!
