Gülnur Özdağlar is an architect who has also worked on graphic design and particularly on digital art after a decade of heavy architectural practice. She won awards in architecture and digital art. After many years of creating on a computer, she began to seek experience in “making” with her hands.

Her experiments on transforming plastics led her to develop her technique based on upcycling plastic bottles, melting them into unique ethereal shapes.

She exhibited her first plastic jewelry collection in 2008 which attracted attention enough to make her leave architectural practice and work as a full-time artist. She has been designing and exhibiting a new collection every year since 2008.
