Johns Hopkins University is one of the most established universi es in the United States through its rich history and strong academics. The site is located on the undergraduate campus across from two freshman dormitories. The program for this design is a smaller scale student center. There are many spaces for the students to inhabit: study rooms, media rooms, a roof terrace, and a sublevel auditorium. The design intent is to provide a modern space that incorporates the aspects of the student atmosphere. The interior spaces are directed towards educa on. The media rooms allow for presenta ons and group studies, while there are individual study spaces for privacy. The roo op and the amphitheater are intended for entertainment purposes: performances, student func ons, videos, perhaps lectures. The visual intent of the project is to act as a lantern on campus for the student body at JHU. The condi oned level displays the silhoue es of those inside, to create an everchanging facade.
Destroying Socialist Regula on Krakow, Poland Study Abroad, 4th Year Krzysztof Bojanowski
This design creates a mesh between the two grids of Krakow: the Socialist and the Historical. The site is located on the edge of both systems, allowing for the design to act as a bridge between them. The geometry is divided into five volumes, with the larger two as open art galleries to help expand the concert hall to the north. The other three volumes are residen al to extend the apartments to the west. There is maximum amount of space with excellent loca on near the riverfront, a main a racon for the developers. This is an ideal design concept to help create a new ar st district in southern Krakow.

The proposed client for this project was the LEAP Collabora ve, a firm that houses both engineers and architects. The concept of this design is to connect the occupants of the Leap Collabora ve with the city of Knoxville. The design must provide for the engineering and design employees with enough space to work eďŹƒciently. The project also focuses on integra ng building systems with an emphasis on sustainability. The site is located within the downtown business district of Knoxville on West Church Street. Each side of the site has a structure at least three stories with the tallest actually being ten stories high, which was an opportunity to create
stronger visual zones for the space. Because of the surrounding buildings, the views are all restricted un l the third height space. At this height, the views are wide open to where one can see almost all of Knoxville, the river, and the mountains. With this site context, the design program starts at the third story with the ground floor ac ng as a double height space that acts as a media park and outdoor performance space, which creates a sense of an urban connec on. This space also acts as outdoor display space for the LEAP Collabora ve. Another aspect of interest towards the design was the opportunity for an open plan, allowing for easily accessible spaces as well as having much flexibility towards program on each floor. The open plan also allows for a significant amount of natural light to enter into the spaces. To accompany this move I also have three facades that are mainly glass, which means almost all the spaces, except for the service core, is well lit with natural light. The floor slabs start to angle and distort to frame specific viewpoints of the city. For example, the balcony shi s towards views of Gay Street and the business district of Knoxville, and the mountainous landscape to the south.
The site design an interac ve “Media Park,� containing a stage and amphitheater, movable projec on screen, and exterior gallery located under the building. This is a proposal to provide more space for the growing ar s c movement that is in the city as well as provide produc on space for the building occupants.
The structure is a fusion between two systems, the concrete core and the steel frame. The concrete core contains the spaces for which the building needs, such as bathrooms, sha space, and egress. The steel frame contains the interac ve programs of the LEAP Collabora ve. The design can be broken down into four phases. The four phases represent the proposed construc on sequence. The first phase is using the site cast concrete, erec ng the core. The service core also allowed for the design to increase in height to provide stronger views and create a ver cal iden ty in downtown Knoxville. The core also is designed with smoke proof enclosures, which was a requirement for the building’s height. The second phase is the steel frame construc on, the lighter
system that is an open frame containing the oďŹƒces and restaurant. The third phase is the addi on of the floor slabs and the glass enclosures. The floor slabs are framed to create exterior balconies for the occupants on each floor. The enclosure is a very common system, with three eleva ons containing exterior glazing to maximize daylight and views. The fourth and final phase is the installa on of the aluminum screen, first the sta onary panels that fasten to the concrete floor slabs, then the operable panels that a ach to the sta onary panels. The panels were designed for mul ple purposes: the prac cal, ac ng as a sun shade, and the ar s c, ac ng as sculptural aesthe c for the design. Overall, analyzing the construc on process was important for the clarity of the project.
Integrated Systems A major component to this project was the atten on to the different building systems. The main system that I focused on in this project was how the building is condi oned. The HVAC was focused into a high level of detail, with a fully designed penthouse. The penthouse is the loca on for the single VAV unit for the en re building. This is the loca on of the chiller, boiler, hot water pumps and cold water pumps. The VAV unit controls all condioned space. The heaviest loads start at the roof floor and slowly decrease in each floor
as it passes each zone. Each floor is a zone for the single VAV system. There is a ver cal sha space reserved on each floor for the ducts to run throughout the building. The largest size is a 4’ x 3’ the smallest being 3’ x 2’. The design for the HVAC system follows the same pa ern as structure and ligh ng, with the main branches following the 10’ zone in each plan then separates into each structural bay. There is one atrium in the design, which is the monumental stair. This is a temperature buffer between the office spaces.

Passive Strategies There are two systems to control dayligh ng and direct sunlight. One is the screen shade system that is operable for the occupants to use. It is an aluminum tube system that diffuses the light to provide shade and decrease the amount of glare in the space. The other system is another operable system that is simply roller shades to provide direct shade to the spaces. This is to completely shade the space, also provides as a back up system for the facade screens. This provides the tenants with maximum daylight control.
Operable windows provides the office spaces with cross ven la on. There is one atrium in the design, which is the monumental stair. This acts as a temperature buffer between the office spaces.

The Urban Mesh: Interlocking the Metropolis 1515 Demonbreun Apartments The design needed to find its own personality within the city of Nashville. This project needs to be a quiet oasis for the residents and a lively des na on for others. Through this unique fusion of program, the design can achieve its own iden ty.
The site is an interes ng geometry with five separate borders. Each one of these site borders can be a public face. This urban interac on is cri cal to the urban context. The building must create public interacon in order to be a successful urban design. The form transforms from simply filling the site as a mass, then subtrac ng. The first subtrac on is the main courtyard, ac ng as the central loca on that the occupants interact with the building. The secondary voids are the atrium that divide the double loaded apartments. The atriums allow for a ver cal connec on between floors, access to natural daylight, and open views for the residents. The last subtrac on is the entry point o Demonbreun, which draws pedestrian traďŹƒc into the central courtyard, ac vates the retail spaces on the ground level, and allows for an interes ng aesthe c for the North facade. Each one of these formal decisions is extremely ra onal, yet s ll creates an originality for the design.
Ground Floor (le , above) Our focus is to maximize the public interacon with the building an to allow for a large amount of sellable retail space. The retail space is also very open, allowing for many types of retail. The proposed retail is a market, a restaurant, workshops, fashion bouques, and art studios.
Typical Floor (le , below) The apartments are located on five floors, including a penthouse level. The interesting geometry of the design allows for many dierent styles of apartments for the occupants. There are also dierent ameni es that occur at each level which creates a ver cal interac on between occupants.
It was cri cal for this project to portray a successful, coherent design that incorporated both the legality and func on of program without any sacrificing crea vity. There is a significant opportunity to address the street environments on Demonbreun St. and Division St. The project strives to create a celebra on of the contemporary urban city lifestyle, as well as provide a comfortable residence for the tenants. This project will ac vate the site by addressing the exis ng urban fabric and connec ng the intersec ng grids of downtown and midtown Nashville. The project will consist of five levels of high quality residen al apartment living with ground floor retail tenancies.
