01 — Practice
EST. MMXII

A small studio with a
long memory — and a
precise hand.

Founded in 2012 by Sanjay Kumar GR, A-3 Archi Arch Associates works at the intersection of architecture, interior design and project management. We keep our practice deliberately small so that every project carries our full attention.

Our work spans private residences, commercial blocks, civic pavilions and institutional briefs — each shaped by close listening, careful documentation and a strong understanding of construction reality on the ground.
