4 We would like to extend our most sincere gratitude to our studio professor, Dr. Michael Kim, for his continuing encouragement, guidance, and overall dedication to our education and for establishing a foundation to complete a successful project. His insight on design integration will continue beyond the realms of this studio, and will prove useful in future projects we may be involved in. We also wish to express our thanks to the members of our “Teaching Office”, Skidmore, Owings, & Merrill, for providing their time, resources, and expertise throughout the execution of the project: Mr. Luke Leung, Mr. Jeffery J. McCarthy, Mr. James Pawlikowski, Mr. Tim Poell, Mr. Kevin Rodenkrich, Mr. Sergio Sadaba, and Mr. Lucas Tryggestad. Finally, we would like to thank our follow classmates for their input during the design process.

Chicago is the largest city in Illinois and the third most populated city in the United States. Incorporated as a town in 1837, it has rich history in architecture that dates back to the mid 19th century. After the Great Chicago Fire of 1871, famous architects such as Daniel Burnham, William LeBaron Jenny, Louis Sullivan, and Ludwig Mies van der Rohe helped revitalize the city with new styles and construction methods through design. The site is within a prominent location of Chicago: the River North Gallery District. At the early stages of the city’s birth, this district was used as an industrial and warehouse sector. Recently, it has experienced immense changes: the development of several high-rise structures, the increase in nightlife activity (primarily due to the sprouting of night clubs and bars) and the continued opening of various restaurants. Sitting at 401 North Wabash Avenue, on the northern edge of the main stem of the Chicago River, the site takes on a unique outline, due to the river’s bend. Although odd in shape, this plot of land offers uninterrupted view corridors from the north, east and south. The site was once occupied by a stand-alone building, the former Chicago Sun-Times headquarters, but was demolished in 2004.

Introduction

Project Goals and Design Objectives

Vision

“Throughout its dramatic history, Chicago has symbolized growth, energy, and innovation, most significantly in American architectural traditions. As a thriving center of culture and commerce, Chicago’s can-do spirit stands out as an inspiration. When planning Trump International Hotel & Tower for Chicago, it is essential we plan to enhance and maintain beauty, culture, sophistication – and heart – of this world-class city.” -Donald Trump

Site Context CIRCULATION

VIEWS FROM SITE Emphasizing the important views from the future tower to its surrounding context provides a clear positioning of the tower in relation to the site.

VIEWS TO SITE

Key views from Wabash Avenue and Michigan Avenue are emphasized to position the tower.

Creating an entry from the northeast gives the opportunity to activate the context and make the tower a node of connection between Wabash Avenue and Michigan Avenue.

Tower location Views from the context to a central point of the site precisely anchors the positioning of the tower.

Site and Meronic Design Implications NOTCH

SKETCH

The addition of the notch along the edges of the building enhance the strength against lateral loads,

Experiments with form, and how the building could be placed on the site with regards to views to and from the site, and circulation. OVAL SHAPE Comfortable, un-forced fit on the site, that maximizes the amounts of views.

CONTEXT

NARROWING

The shape contrasts with much of Chicagoâ&#x20AC;&#x2122;s Miesian geometries, to provide a simple, but distinct addition to the cityâ&#x20AC;&#x2122;s skyline.

The tower tapers as it goes up in order to provide appropriate lease space for the program inside. It also creates the illusion of extra height at the base

EXTRUDE

PODIUM

The oblong shape allows for good distribution of wind, to reduce the lateral loads acting upon the structure.

A podium at the base of the tower creates a welcoming, human scale entry for visitors, as well as a transition for the tower to meet the ground.

APPENDIX A minutes FROM MID-REVIEW FRIDAY, OCTOBER 19

• Residential wants to be in the sky, office on the ground • Security check-ins and do other people want to see the hotel goers? • Think of how someone would want to get to the building, and the entrances • How do we want people to go from the public realm to the observation deck or restaurant? • Further design ball room (large, small), pre-function, kitchen, storage • Better retail and lobby connection • Parking and loading dock design overall • Circulation within each program (individual lobbies) • Site development and how the design will bring money to the developer • Sustainability as better functioning details, rather than attachments • More service elevators • More elevators to the observation and restaurant levels • Make 45,000 square feet per elevator, 1:100 units • More comfortable journey through stairs and vertical circulation • Creation of atriums and making them functional and justifiable • Fix the curtain wall to be economical • Further design the HVAC system and where the mechanical floors are located • Make a more streamline design • Simple construction and cost effective structure

CHICAGO LOFT - Concept #1

CHICAGO CRYSTAL - Concept #2

A natural response to the site boundary which softens the edges providing equal viewing opportunities.

Emphasizes the site by tracing its boundaries and maximizing land usage.

The oval shape maximizes land use while increasing views to the city, river, and lake. The building tapers as it goes up to reduce the overall mass impact on its immediate context

The footprint is faceted into a crystal shape to draw views towards other major landmarks in Chicago. The building tapers along the southwest face to create a focal point along Wabash Avenue.
