Interested in our Mellow Joint™ system?
Would you like to get a taste of our structures designs?



In Mellow Designs we develop alternative usage cases for already existing products. We create system solutions for temporary pop-up architecture and implement unused materials into pop-up architecture to make the building process quick, simple, and accessible.


We develop products that have circularity in its core. We focus on prolonging the material’s life cycle, cherishing its value, and reducing its environmental impact.


Zero-waste philosophy inspires us. Our solutions  can be repurposed and engage you to repurpose. Our products are 100% recyclable, and we only use sustainable materials.
