Pet Care, Toys, Supplies and Products for Animals Design Accordio Pet House by Yongwook Seong Accordio is a design study about portable pet houses. The silicone pet house is light-weighted and collapsible as an accordion-like structure. It is easy to clean and carry during outdoor activities and travels. This silicone house can be compressed in a 1/6 size by pushing both sides. A fabric cushion can be conveniently fit into the collapsed form for portability. Each magnetic frame (a total of 8) is reinforced for structural stability. Once collapsed, these frames adhere each other and keep it compact and portable.
