Designers are constantly coming up with new flexible solutions for urban office spaces– from multi-use backyard structures to road-ready office pods . Exploring this concept further, Portland-based studio LOS OSOS teamed up with Coroflot, a website that connects designers with clients and peers, to design and build a mobile trailer-office which can be installed on any unoccupied urban lot. Their first Mobile Work Unit (MWU) is located inside an old ambulance garage in downtown Portland, and functions as a workspace for the retail shop Hand-Eye Supply.

The team wheeled a trailer into the space and built the structure in place using a post-and-beam structural system, which limits the wall’s structural role. The designers used polycarbonate as siding in order to allow natural light to reach the interior while functioning as an acoustic barrier. Locally-sourced, custom-milled, and kiln-dried wood from Douglas fir trees was used for the walls, while modular furniture systems, specially developed for the project, define different personal spaces. The new office space can be repurposed and adjusted for different work scenarios. It can be easily adapted and expanded to accommodate a growing company.

“I see the next version in so many different flavors—office, retail, showroom, home,” said Laurence Sarrazin, principal of LOS OSOS. “And each has its own challenges and parameters that would determine what the skin would be, the size, how much light is let in, how much storage, all those fun design problems. It would be exciting to find manufacturers.”
