:: Scioto Pedestrian Bridge

:: Dublin, Ohio | Under Construction As the central locus for a broad redevelopment plan, this iconic pedestrian bridge creates a vibrant new link between the historic district of the City of Dublin and a new commercial district across the meandering Scioto River to the East. The 14-foot wide deck soars across a new network of trails through the verdant floodplain of the river below. The deck lifts from a plaza at the western edge of the riverâ&#x20AC;&#x2122;s banks, rises through the canopy of trees and passes through the eye of the needle at the central tower. The sinuous curve of the bridge is suspended on one side only, adding to the weightlessness of the procession from the old city to the modern new hub. Construction is underway on this project. It is expected to be completed in early 2019.

:: Dome Residence

:: Big Sur, California | Under Construction This residence is perched on a cliff overlooking the often tumultuous Big Sur coast. The proposal for the main portion of the house is a ribbed structural concrete dome. The center of the lamella pattern is offset from the center of the dome so the size of the openings increase as the system twists towards the ocean side of the house. This allows for the maintenance of the spectacular views and for additional structure to be added near the cut out entry ring on the land side of the structure. The ribs were added as part of a redesign while work was commencing, creating a complex coordination requirement. In the end, a continuous steel ring was embedded into the network of piles and grade beams to allow for some flexibility in the rib placement. A large number of iterations were executed to envelope the largest change in thrust, ring stress, and uplift between rib points.

:: Observation Tower

:: Greenville, SC | Design Development Located just upstream from the successful Falls Park on the Reedy, the proposed Reedy River Park builds and expands on the reinvigorated downtown of Greenville, SC. The area is already used heavily by the Cityâ&#x20AC;&#x2122;s active biking and running communities and so forms a natural locus for the planned park and surrounding commercial and residential redevelopment. Endrestudio is designing an extensive list of structures in the master plan, including several pedestrian bridges, an event hall, iconic entry structures, shade structures for the great lawn, and an observation tower. The observation tower has undergone several iterations including this proposal for a cable stayed mast with an observation ring suspended 80 ft off the ground. An elevator runs through the central mast structure, and the stairs are supported on the surface of the cable net, creating a unique procession as well as fantastic view.

:: Lion Mountain Aviary

:: Suzhou, China | Design Development As part of a massive redevelopment of the Lion Mountain recreational area in Suzhou we developed a novel proposal for the adaptive reuse of converting an existing defunct roller coaster into a massive aviary. The roller coaster becomes the skeleton supporting 56 cable net panels. Additional structure will be added where necessary to achieve the curvatures required for efficiency and stability. The interior of the nearly 16,000 m2 structure will be developed into several habitats and interpretative walks. At the highest space a visitor center and elevated path allows for visitors to observe the birds from above. Custom tools were developed to iteratively adjust the pretensioning of the system. This allowed the panels to be balanced across the roller coaster spines to minimize out of plane loads under all but the most extreme external load cases.

:: Chao Residence

:: Los Altos, California | 2017 Twisted steel rods emerge from below the hillside, rising past a small footbridge and exploding into a canopy of wood rafters. The roof they support floats three feet above the rest of the house allowing for 360 degrees of clear story window. The branches act as a discontinuous diaphragm, linked together with a spiral rod to redistribute torsion into compression and tension in the adjacent quadrants.

:: Perforated Plate Stair

:: San Francisco, California | 2017 :: Featured in Dwell magazine, Feb 2018 This thin folded plate stair was designed to weave through an atrium in a residence in San Francisco. The perforated plate creates a filter through which the various levels of the house are connected. The structural analysis of the system required research and testing of the effect of different perforated patterns on the material properties of the folded plate. Although the design and construction of the stair was complex, the biggest challenge turned out to be painting it without clogging the perforations.

:: Civic Center Play Structures :: San Francisco, California | Jan 2018

Fundamental structural principals combined with parametric form generation can be loads of fun, as demonstrated by the unique play structures for the Helen Diller Civic Center Park. On the largest structure, three layers of play nets are interconnected through punched funnels and ringed with a walkway that would make any child - or adult - giddy with delight. The other large structure is an open helix, which uses a twisting pathway and connected net to form a continuously rising surface which limits the fall height to less than two feet. The structures were fabricated in Germany and assembled on site. This created significant restrictions on the original assembly scheme. This required a coordinated redesign between endrestudio and Kompan play systems. The play structures have been assembled and installed and are awaiting the grand opening and dedication in late January of 2018.

:: SOAP

:: BIOMS Research Team | UC Berkeley Project Team :: Professor Maria-Paz Gutierrez, Professor Slav Hermanowicz, Professor Luke Lee David Campbell, Vivek Rao, Henry Kagey, Pablo Hernandez, Peter Suen, Charles Irby SOAP (Solar Optic Active Panel) was conceived as a way to heat and treat greywater in a building facade, thereby simultaneously generating energy and recycling water on site. This requires an integration of design across scales and disciplines, and has the potential to reduce overall water and energy consumption and by extension reduce wear on our overtaxed and aging infrastructure. In addition, in the developing world where per capita consumption is relatively low but the cost of water and energy is very high, the SOAP panel can have a significant impact on an individualâ&#x20AC;&#x2122;s quality of life. This continuing research is funded by an NSF EFRI SEED grant, and includes professors, doctoral candidates, post-docs, graduate students, and undergrads working on an interdisciplinary team including Architecture, BioEngineering, Mechanical Engineering, and Environmental Engineering.

:: Flex Pavilion

::with Kyle Johnson::Yu Zheng::Qingzhi Li The pavilion began as an investigation of using bending as an activating force rather than the traditional approach of designing with the intent of minimizing it. We were particularly interested in manipulating the bending stiffness of birch plywood by creating ‘soft zones’ through the removal of material, and exploring the spatial opportunities latent in this controlled collapse approach. The methods of creating the soft hinges fell into two strategies: kerfing, which effectively reduced the width of the surface, and material rastering, whereby we reduced the depth of the wood substrate. The pavilion itself was conceived as a light canopy connecting two benches. The design space was explored parametrically through a robust model developed in Daniel Piker’s Kangaroo plug in for grasshopper. The system allowed a user to tweak the layout and soft zone pattern to their needs, and then produced a cut pattern for a CNC mill.

:: Graduation Pavilion

:: Illinois Institute of Technology | Proposal This proposal for the Illinois Institute of Technology in Chicago was intended primarily as a large pavilion for the general graduation every spring. In developing the collapsible, modular system we saw an opportunity to allow the modules to be arranged in multiple configurations by developing the structure to be stable in both singular and multiple conditions. The fabric covering transitions from the Instituteâ&#x20AC;&#x2122;s crimson to a semi transparent membrane at the supports. This facilitates both the erection of the system and provides a method of bringing in daylight in an almost lamp-like quality. The system drains through the support structure, allowing for use in inclement weather.
