diverse programs in a mixed-use building require the conduction of similaractivities. instead of partitioning activities sporadically among programs, they
could be grouped in common “mixing spaces” and programmatic elements would be dispersed around them, thereby streamlining the actual actions

redevelopment of a suburban lincoln commercial centerspring, 2010
given ever increasing petrol prices, longer commutes, and a more and morepolluted environment, the sprawling tendencies of the 20th century are nolonger desirable. what if instead of building on new ground, we could graft
vibrant program into existing, underutilized urban spaces?
project four:hp
monocoque healthcare partitionsummer, 2012
abandoning traditional frame construction in the healthcare environmentallows for the development of a new typology, where systems and
interface are not only integrated into the structure, they determineits form
unconventioncapitalizing on an intersection of cycling paths used by residents for
recreation and students moving between campuses, an expansion of the university health system becomes a nexus of activity that embraces a broader
idea of health that is not simply reactive, but built on a framework of an active, robust lifestyle

typical activities
typical architecture is traditionally organized programmatically, with similar uses placed in close proximity to achieve “cohesion.” This method, however, ignores the fact that diverse programs may require the conduction of similar activi-ties. Instead of partitioning activities sporadically among programs, they could be grouped in common “mixing spaces” and programmatic elements would be dispersed around them as necessary, thereby streamlining the accommodation of actual actions

mixing spacebecause the mixing spaces function differently than the more typical office and retail spaces spread throughout the building, allowing people to gather freely and adjust the space to meet undefined, spontaneous needs, these spaces must be more open and multifunctional. the mixing spaces require a versatile structural system that can handle loads with few intermittent supports. the mixing spaces are essentally narrow towers built around the service cores, so they can be supported by a diagrid system that can more evenly distribute loads, easily handle lateral forces, and is ingrained with an inherent redundancy, thus requiring only an outer structural skin for support.

our dependence on automobiles has had a devastating effects on our environment.- we
actually use more energy getting to work than we use while we’re there, leading to rapid
depletion of our irreplacable resources, as well as adding heavy pollution to our environment
with only higher oil prices on the horizon, a continued reliance on the car would mean
that simply getting to where we need to be would require larger and larger portions of our
budgets, resulting in a decline in our overall quality of life
as we continually expand the reach of our concrete landscape, our environment will be further afflicted by
problems of contaminated runoff and the urban heat island effect. these problems affect not only our local ecosystem, but have lasting results all over the world

the site is in a condition that does not allow it function asa vibrant urban center. It is littered with vacant lots that lendan air of blight to the area, vast parking lots make the spaceseem less hospitable while impermiable pavement createsrunoff problems, and retailers, dependent almost entirely uponautomobile traffic, fare poorly in low-visibility areas away from South St.
what if we could apply the life-saving power of the graft to architecture?what if we viewed cold, under-utilized areas as wounds to a vibrant city?could we take a more intense, sustainable model, or the best featuresof multiple models throughout the city and graft them onto the wound?
the solution: graft
primary path
secondary path
the western half of the site is less porousbecause bordering yards and retaining wallsforce pedestrians to use the streets
at the southern edge of thesite, bordering an establishedneighborhood of single family houses, plots are smaller
spaces are porous on theeastern part of the site, whereusers can meander in fromthe park
at the nothern end of the site,bordering South St, the scale ofthe building plots is large
where no longer useful,buildings are destroyed
if structures must beretained, glass walls allow path users to see their destinations
by grafting more dense, useful programs into the underutilized paved areasof the site (transplanting parking to garages or on street spaces), the site ispoised to take on a much more vibrant life. meanwhile, site connections ona pedestrian and cyclist scale are reinforced, helping to improve accessiblityand integrate the site with surrounding infrastructure
when a being is wounded to an extent that they can no longer function in a meaningful capacity, they can either be left to die, or they can, with precision surgury, be saved. as long as it still has its roots, the key components that sustain life, a new body can be grafted onto the wound. as time goes on, the two grow together and ultimately it is the foreignattachment that overtakes the scion as the dominant presence

recreational path
by locating the health center at the intersection of two networks of cycling paths (one primarily used by students and one for recreation), then drawing those paths into a junction, the resulting intersection has the potential to become a living hub of social, healthy activity
outdoor social space
integration of healthy activities works in section as well as in plan. while different types of activities may be seperated by floors, connections are designed not only to make moving between areas intuitive, but also to expose users to as much variety of activity as possible, so as to draw them seamlessly from one to another while still retaining the integrity of the spaces. the junctions where these connections occur form hybrid phenotypes, where the behaviors of the environments around it allow limitless possibilities for activity

frame constructionthe traditional structural frame of a partition is at odds with the needs of the systems wedged within it. system components often need to be routed perpendicular to the direction of the frame, corrupting the formal logic and structural integrity of the frame.
monocoque constructionin a monocoque, where there is no internal frame, systems are able to define their own logic. because the structure is no longer dependent on a rigid framework, the systems inside the wall, in tandem with their external interfaces, can begin to define the form of the structure.
chassis constructionbecause the body and the structure are separate entities, not only is the scooter heavier and more material intensive, but internal links must be tightly compressed within small gaps between the two.
monocoque constructionWhen structure and skin are unified, the scooter becomes cheaper to manufacture, more efficient to drive, and easier to ride, while unburdoned cavities in the monocoque allow shorter, more direct linkages.
Vespa LX 150 and GTS 250at a glance, the two Vespas appear nearly identical, but underneath their chic Italian exteriors lay entirely different foundations. whereas the first utilizes a traditional frame chassis, onto which the body panels are applied, the latter is built around a monocoque, in which the structure and the body are one.
the sheer volume of systems that need to be integrated into healthcare partitions often leads to an inefficient, convoluted organization when packed into a traditional frame wall. this project sought to explore alternative construction techniques of monocoque structures to allow better integration of system and skin, while providing parametric control of the body in response to criteria like structural stresses, bifurcation, and air distribution

compact bonecompact bone is the stiff, outer layer of the bone that provides much of a bone’s strength. compact tissue, which makes up 80% of total bone mass, is far denser than cancellous bone, but is porous enough to allow some blood vessels to flow through
task lightingLighting emitted from the partition varies in intensity based on the orientation of the surface, allowing only a small amount to shine directly on occupants while optimally lighting work surfaces
HINS lightingHINS lighting provides a convenient alternative to hand washing for sanitizing skin that may contact the patient
ventilationPerforation in the partition varies in density and size, directing air where it is most needed
cancellous bonecancellous bone is a sponge-like cellular structure that both forms cavities for integral systems and lessens the overall weight of the bone. the porosity and thickness of cancellous bone varies with the structural and functional needs of the bone.
blood vessels wind through the cavities in the cancellous bone. While blood vessels also follow osteons in compact bone, there they constricted to small direct passages parallel to the direction of the bone. Within the cancellous bone, porous cavities allaw free adaptation to particular needs.
blood vessels
by conceiving of the partition as a monocoque, in which the systems and interface are integrated into the skin, the relationship of systems which had previously competed for space becomes less of a problem of organization within the form and instead is embraced as a composing element of the form itself. much like a bone wraps structure around critical blood production facilities, developing different densities to respond to localized needs of strength and lightness, the partition adapts to programmatic and structural needs, allowing it to be optimized for specific conditions.
connectaugmenting the skin’s ability to deal with structural stresses, particularly lateral forces, a ‘poche tissue’ creates a cellular structure within the wall, adding extra strength. like the skin thickness, the tissue reacts to stresses on the wall surface, providing more reinforcement where the wall complexity is greatest.
thickenthe skin of the partition varies in thickness based on the stresses imbued within it, becoming narrow and light where forces are minimal and deeper where the structure is under the most pressure, particularly around folds in the surface.
supportbecause the internal systems can no longer attach to a regular frame, the poche tissue must be able to provide adequate support. this support, however, does not need to be evenly distributed; rather they are attracted to elements within the space, creating more points of connection where they are needed and dissipating where they are not.
