O/I design studio is a London based practice working on architecture, interior design and landscape projects. O/I means a state of balance; we pursue a harmonious arrangement that holds every detail of a building together, making it integral from inside out. We actively blur boundaries between space, as well as taking inspiration from architectural history, vernacular traditions, crafts and environment. We address architecture through our unique natural process that adapts contexts and clients' requirements, creatively.
We work with private clients and charitable organisations, in the UK and worldwide. Our projects range from refurbishments, house extensions, artist studios and landscape commissions in London; to larger projects abroad such as a private villa in UAE and a chapel in Taiwan.
