“It is not the strongest of the species that survives, nor the most intelligent that survives. It is the one that is the most adaptable to change.” – Charles Darwin
THESIS INTRODUCTION THE WHERE & THE WHAT? Galapagos Giant Land Tortoise Critically Endangered
Known for their immense bio-diversity and density of endemic species, the Galapagos islands were largely unexplored until Charles Darwin arrived in 1835. Located 60 miles off the west coast of Ecuador, the UNESCO World Heritage site can be difficult to get to and requires thorough bio-security screening measures before entry is permitted. These 13 islands are a living microcosm of evolution and adaptation and have become a hub for scientists and tourists alike. Unfortunately, human occupation of the islands has had widespread repercussions on plant and animal-life, which now demand human intervention for a chance to fight extinction. Thoughtful design strategies that consider their delicate contexts could help save the Galapagos, a live laboratory of evolution, from destruction. These islands, the place where we discovered evolution of the natural environment, could set a global precedent for how the built environment can rebuild and support the natural environment and be equally as adaptable to change as nature itself.

THESIS INTRODUCTION THE WHO?
“The long-term goal of The Giant Tortoise Restoration Initiative (GTRI) is to restore tortoise populations to their historical distribution and numbers across the Galapagos:
Tortoise Research & Conservation Centers
1. Research & conservation of tortoises, vegetation, etc. on targeted islands 2. Breeding & rearing tortoises of threatened species 3. Repopulation of islands where tortoises went extinct
4. Research and management of tortoise-human interaction and conflicts This initiative is carried out by the Charles Darwin Research Station, the Galapagos National Park Directive (GNPD), and numerous visiting scientists & volunteers.” -The Galapagos Conservancy

DESIGN STATEMENT THE HOW?
As architects, we often say things like ‘let the building breathe’. We also provide services to our buildings like air, water, and sun; the same as people and animals require. We say that buildings have a lifespan. If this is true, then surely our buildings live in similar ways to those things that are biologically “alive”. Therefore,
Buildings, like all living things, must “adapt or die”.

Lessons Learned from Q1
- divide program groups to provide multiple walls for natural ventilation - modify approach to building to be more inviting than at a corner - coordinate circulation and approach with animal maneuverability from dock - explore building angle adjustments on site to reduce excavation impact - butterfly roofs internalize sustainable systems - respond to symmetry over equator through roofline and structural grid - curved roof externalizes sustainable systems to building perimeter
Primary Plan Option at Start of Q2
Between Terms Development
Pros: - stronger, direct approach - connectivity with office zone at center of plan - greater opportunities for natural ventilation - grouping of conditioned spaces to the east for less harsh sun Cons: - larger building footprint increases site impact, material usage, and reduces the net to gross efficiency ratio GALAPAGOS ANIMAL HOSPITAL & REHABILITATION CENTER | AMANDA COHEN

BUILDING PLAN ITERATIONS Q2 - Exploratory Plan Options To Address the Cons of: - weak site axis connection with building - large footprint Proposed Changes: - divide program groups further to separate but related buildings of varying sizes - position of building on the site - central arrival node from dock - independent structural grids to respond to each program group
Q2 - Floor Plan - return to primary plan option at the start of Q2 after exploratory iterations To Address the Cons of: - weak site axis connection with building - position of building on the site Proposed Changes: - rotate building to be parallel to contours - rotate office block to create node at the building approach, and along site axis - explore a less rectangular office block to create an arrival point and a more structured gathering space for clinicians

Final Jury Feedback & Responses - With the bamboo structure at the forefront of the design, additional documentation of the truss assembly would benefit the readers understanding of the integration of other building elements, like the gutters. - I would like to further explore the detailing of these assemblies and develop iterations for some of my exposed sustainability systems, like the perimeter gutter profiles to make them more distinctive yet expressive, the materiality and rhythm of the downspouts, and the form of the water retention tanks around my building. Additionally, I plan to add 3D axonometrics of these enlarged conditions to both isolate the assembly from the building mass while also getting a preliminary understanding of the experience created by the elements. - The experience under the structure is unique to this roof form, and with the possibility of future program adaptation and structure re-use, having more views from under the structure or within individual exam rooms would speak to how the users, not just observers appreciate the structure. - With more time, I would have chosen to document the experience from within a typical exam or triage room, as well as an exploded look at the ceiling, screen, and lighting assembly covering these spaces. While I feel that I have thought through countless aspects of the design, the editing process and prioritization was challenging during final production. I think it could be an interesting exercise to consider future re-uses of the structure, how other building systems may be repurposed, and consider what the future needs of the Darwin Institute may eventually be.

Original Thesis Expectations and Reflections Over the course of this last year, my outlook towards my senior thesis has truly evolved and grown. Aside from the shift from my original proposal last spring upon visiting the Galapagos myself in the fall, I learned a lot about perseverance, setting realistic yet challenging deadlines for myself, and feel that I have truly explored the boundaries of my research and design capabilities. I am very glad I developed a unique project that I will likely never have an equivalent opportunity to design again during my career. Being able to shape my own path this past year, choose what to research, which programs on my site to develop, and learning how to present my ideas to an educated jury as well as lay people, has allowed me to consistently reevaluate my project goals and strategies with each week. At the start of thesis, and even through earlier years at Drexel, I expected Thesis to be a ‘head down and work’ atmosphere because I knew it was a solo project and most assignments were self paced. I was pleasantly surprised by how many people I could I involve in the process, from site visits, mentors, peer reviews, and truly immerse myself in the design process while communicating with others. No project is a solo project, and the guidance I received from everyone was wildly enriching to my process and final design. My primary realization of this year is that no matter what external factors may appear, getting through Thesis is an accomplishment in and of itself, to be confident in the knowledge I have collected and proud of the design I put forward in the end, but also, that a design is never quite finished.
