Portillo Home Concept Store For the design of the Portillo Home Concept store, we designed an undulating ceiling scape that not only enhanced the overall ambience of the space, but also helped to connect the smaller upper story with the large gallery in the basement through the continuous flow of the form down the stairwell. The implied undulating surfaces also integrated lighting and display surfaces, while gently suggesting customer flow through the large store. We researched the client’s manufacturing capabilities and developed a modular system that could be easily made, transported and installed onsite with minimum cost.
