KASA Design Collective is a multifaceted design firm based in Chennai, India, founded by architects Karthikeyan and Sangeetha Patrick.
The studio is committed to delivering innovative, context-driven, and sustainable design solutions across diverse disciplines, including architecture, interior design, landscape design, and product design.

Both partners are alumni of the School of Architecture and Planning, Anna University, Chennai, graduating from the 2003–2008 batch.
They began their professional journey at Mancini Enterprises, a German-based architectural firm in Chennai known for its expertise in luxury residences and meticulous detailing. During their tenure of over two years, they gained significant exposure to high-end residential design and refined their eye for craftsmanship and precision.

In 2010, they co-founded WeBe Design Lab alongside seven other partners—an important chapter that shaped their collaborative and interdisciplinary approach to design.

In 2021, drawing from over a decade of experience and a desire to pursue a more refined and personal design philosophy, they established KASA Design Collective. Today, the studio operates at the intersection of craft, context, and clarity, with a focus on creating spaces that are both meaningful and enduring.
