Interior view showcasing the reading rooms, how the slope of the bridge adds a dynamic sense to the experience, and kayakers rowing between the pontoons.

Bird’s eye view toward the west illustrates the layered structure, green roof, and tide pool(right) against the Olympic mountains vista. The green roofs have openings for trees to grow outwards and upwards, and providing light to help the lower levels.

This southern-looking view shows Luna Rises against the hills and shoreline of Alki Point.This northeastern view towards Seattle includes the suspended library, a deck area for a small cafe, and additional reading rooms.

BACKGROUNDThe Floating Luna project is a project focused on creating innovative repurposing concepts for the historic Evergreen Point Bridge, which is to be decommissioned in 2014. The staging location for this project is Alki Point, located at the northernmost point of West Seattle. In the early 1900’s, Alki Point was a bustling center of activity and home to Luna Park, an extravagant amusement park that served to bring together the community with attractions such as roller coasters, and heated saltwater swimming pools. It is this park that provided the first sparks of inspiration for the Floating Luna project.

VISIONOur vision was to develop a destination which would serve not only the immediate area, but the greater seattle community and beyond. From this, we focused our goals on designing a venue for education and outreach, recreation, and inspiration.

We wanted to build a destination where the public could come to learn about the history of the site and renewable energy, and where public institutions could participate in research projects. Reflecting upon the history of the site, we also wanted to incorporate the spirit of Luna Park, but with a modern view towards

environmental responsibility, and sustainability.

IDEASWhen developing detailed project ideas, we focused on the question: what is

the soul of Seattle? Behind the lingering clouds shrouding a cool, crisp, and sometimes rainy city, lies a vibrant community with a culture that places

strong values upon education, environmental responsibility, and interplay of nature and urban life. Floating Luna is focused around design elements inspired by a blend of these principles, by including a shallow infinity tide pool, wave based power generation, and a small communal library with many scattered reading rooms.

SITE PLANFor the site plan, we chose design a pilot site using half of the total set of pontoons, leaving the rest for a separate sister site. Not using all the pontoons in one location

lessens the environmental impact at any single site. We also reused the existing raised portions of the bridge already attached on the pontoons to create experiences and functionality on multiple levels. The site plan arrangement represents our core design principles by re-molding the cold, monolithic, lifeless, and rigid

concrete form into something dynamic, welcoming, and intertwined with nature.

REMAINS OF LUNA PARK

WAVE POWERAt the far ends of some pontoons, wave-based power generators are placed into the water, beneath the bridge sections for harvesting natural wave and tidal

changes of the Puget Sound, supplying enough energy for the site to be self-sufficient. This feature would provide pioneering research opportunities with local universities, and a space where the public can come to learn about wave energy harvesting.

TIDE POOLAs the tide rises and falls, parts of the trail surface will appear and disappear below the waterline. People typically experience the ocean waters at a distance, retreating or advancing tides ebb and flow, but this design lets them

be surrounded by, play in, and enjoy nature directly in the ocean waters during high tides. As the waters recede, some surfaces of the pool would reveal naturally occurring wildlife attached to the structure of the bridge.

LIBRARY & READING ROOMSSince such a large population of Seattle highly value education, we wanted to incorporate a small, community library space that would be powered by the wave energy generators, and also by recently developed transparent solar panels, serving as windows. Within the library, which is supported by the existing bridge columns, reside historical information about the Alki area and

small galleries of significant local artifacts. People could borrow the books and enjoy them in the open-air reading rooms, where people can take a respite from the busier areas nearby, and read while surrounded views of Seattle and the Olympic mountains.
