Margaret Joplin established Design Collaborations in 1990. She brings an exciting range of experience to projects. Having designed both public art, urban, commercial, and residential landscapes, she is well prepared and willing to undertake any project. She has designed, fabricated, installed and constructed projects; and has an extensive experience in creating comfortable, welcoming environments. 


She also established in 1990, Design Collaborations with her husband Michael Joplin, as an innovative design firm creating hand-made glass works, public art and landscape architecture located in Tucson, Arizona. The name is informed by our core design philosophy that excellent design is produced through collaboration and participation, and we strive to carry that to all the different types of work we do.


She creates hand-made cast glass works. Using the age-old technique of lost wax casting. She crafts forms ranging in shape from jewel-like elements to large sculptural pieces.  Her work, which is featured in settings ranging from private gardens to urban spaces, blends industrial gear and traditional bead forms.  By combing the creative talents of our team, we meld fragility and solidity, transparency and opacity, and visual and tactile beauty.
