OSD | Outside is a group of interdisciplinary designers and strategic thinkers actively working to create a future that ensures the health of our planet while dignifying the everyday lives of diverse communities. 

OSD specializes in resilient urban communities, investigating new hybrids of technology and natural systems. OSD works within the realm of urban design, landscape architecture, and architectural design. Our designs focus on public space, master planning, community engagement, coastal and upland flood protection, and mobility.

The extensive experience of the core team means that OSD is engaged with a network of innovative and diverse professionals - engineers, ecologists, artists, economists and developers - to ask what kind of social and ecological environments we need, and how emerging technologies can actively serve the interests of our everyday lives and our natural worlds.
