Turning loss to advantage, he creates a theatre where these things are reinstated, pending further use; by virtue of their relationship to their surroundings, they encompass a space which far exceeds their immediate limits.
Kolleri has an affiliation with working processes which marginalizes any message that stands apart from the act of putting a piece together.

He runs the Shilpapaddiam a centre for sculpture in Pattiam, Kerala.
