Project title: A research and design process for Rooftop 4: The Fifth Façade
6. We will establish an ecological framework in the city which integrates social needs and environmental necessities. 7. As a tool to elicit dialog, critique, and problem solving, Description: Unexpectedly, our firm was asked to design a we created a large format charcoal drawing that acted as a public rooftop park atop a large, new building in Eujeungbu, provocation for conversations with others. Taking advantage Korea. This project led to two other rooftop projects and of charcoal as a medium that is both additive and subtractive, suddenly, without planning to do so, we found ourselves the drawing has become a living document that visually actively engaged in a new typology. Rooftop 4 is a conceptual tracks the conversations and critique from members of our project looking to expand the design thinking within our studio community and our firm. for a project typology that was entirely new to us. 8. We will share conclusions, research and design ideas publicly as they are developed through a broadsheet that will Design Precepts: be published in print and online. 1. We want to examine the full potential for the top layer (the fifth façade) of cities to stimulate critical discussion for The Idea: Rooftop 4: The Fifth Façade imagines an both social and ecological advancements. interconnected series of public spaces intended to transform 2. We will integrate research on the history of rooftop a landscape currently comprised of HVAC equipment, design precedents, starting with depictions of the Hanging ductwork, “dead” water towers and elevator machine rooms.

We will research and promote existing movements and production, playgrounds, new types of convening and revised integrate components that could thrive on the Fifth Façade notions about “public” and “private”. into a single composition. We will invite others to use and build on this work. 4. We will use our neighborhood in Seattle’s Pioneer Square as the location for this conceptual intervention. 5. Our design studies should not be limited by actual feasibility. We believe the model, or its components, could be translated to other aspects, regions and building project types.

The Fifth Façade
The upper layer of cities in its current state creates vast amounts of under-utilized space
Previously completed rooftop gardens in Seoul, South Korea became a prototype for how cities might grow in the future, turning the tops of buildings into public spaces and parks
JUNGLE MOUSE PLAN
A series of conversations were held with invited community members: artists, sustainability consultants, urban planners and historians. The charcoal drawing became a living document, visually tracking the research and dialogues that take place.
