Jordan Parnass Digital Architecture (JPDA) is now known as Circular logo


Sustainable design for all.

Circular helps our clients create sustainable architecture, interiors and experience design.

We design with empathy and integrity to create solutions that make the world a better place to live, capturing value for our clients, society and the environment.

Our vision is to be a global leader in producing designs for innovative, resilient, human-centered spaces and systems that promote happiness, delight, healthfulness and community.

We embrace a cradle-to-cradle systems-based approach to all aspects of design and customer experience (CX), that leverages lifecycle, societal benefit and environmental regeneration as forces for positive change.

The Circular Economy is built on the principles of eliminating linear waste and pollution from the outset, keeping products and materials in use at their highest value, and regenerating natural systems.

Circular CX is the result of orchestrating interactions and experiences, and transforming systems to create material, spatial, visual and experiential environments for habitation.

Circular Design is a collaborative, iterative process that is inclusive, holistic and applies circular economy principles at the design stage of everything.

Circular is a Certified B Corporation verified by B Lab to meet the highest standards of social and environmental performance, transparency, and accountability.
