A sustainable, carbon-neutral vision must be formulated before planning begins. Architectural competition is an integral part of innovative ideas, strategies, and visions of the future in the field of consistent designs. It pushes boundaries of creativity and helps source the best and most unique designs for projects, fueling community engagement, and holistic development. 
We support developing specific sustainability goals for the award, analyze the competition entries, and as experts or jury members, we contribute to the decision-making process for the most sustainable design.

C5 makes it easier to build sustainably. We offer creative consulting for circular and certified construction.
