CS Architecture LLC is a full service architecture, interior design and consulting firm established in 1992, based in Redding, Connecticut. Its partners, Jason Chai and Anna Sy, established CS Design Consultancy, Inc. in Manila in 1994, in response to increasing demand for services throughout Asia. Currently, the firm handles a wide range of corporate, commercial, educational and residential projects in North America and South East Asia.


The common thread in the diverse range of designs and locales in the work of CS Architecture is a recognition and accommodation of local architectural heritage, building traditions, climatic conditions, and, especially, the particular needs of our clients.
