island space evolved from the success of C2 Studio which was founded in 1991 in Hawaii and branched out to Bangkok in 1994. In less than 10 years the company employed 50 architects, interior designers and graphic artists.
Both island space and C2 are the brain child of founder. William Callahan has received the prestigious SOM Foundation traveling fellowship award and since then his creative work has been widely published and exhibited worldwide.
island space is now continuing to grow to the next integration by the Callahan’s family.
We believe to develop property, design, and build the environment that enrich our lives while protecting our planet.
