5D STUDIO is a multidisciplinary studio with expertise in graphic design (2D) and contract furniture and interior design (3D). 5D is founded on the principals’ passion for design. Our studio is deliberately small in size, allowing us to do what we love – design – while guaranteeing that our clients work only with highly experienced designers. We provide our clients personal attention and take a genuine interest in their creative and strategic goals. We come to understand the heart of our client’s business, its language, environment, and competition, and we address each project with fresh, creative solutions supported by marketing expertise. Our work achieves a subtle balance that is grounded in function, expressed in form, and emotionally evocative. 5D. Small in size. Intense in scope.
