Architecture and interior design working together hand in glove

We call it design collaboration

What We Do

Founded in 1998, DECA is an independent architecture and interior design studio creating sustainable environments for regional and international clients.

We purposefully blur the lines between interior design and architecture. They don’t operate alone, but are part of a holistic vision. It’s this sense of design collaboration that is at the heart of our practice—driving our commitment to research, flexible solutions, and creative thinking that results in award-winning spaces.
