INTRODUCTION

This mixed-use tower responds to the inherent striated nature of high-rise developments, relocating amenity program from the traditional podium placement into a range of vertically connected spatial experiences. Through this organizational change, the repetitive/horizontal section is broken and replaced with diversified, networked space.

The programs are separated into a residential and hotel component which are connected by the Equinox Fitness Club and other shared amenities. At the base, a combination of commercial, retail, and recreational programs form the podium of the project in order to match the industrial scale of the surrounding buildings. The towers are subdivided into two iterations of the “house� which contain four floors of residences or hotel rooms that are integrated into a range of amenity spaces. Within these smaller communities, programs are organized to transition from public to private through location and spatial scale. Breaking free from the standard Cartesian grid, the project’s spatial arrangements encourage chance encounters and a more interactive living environment.

SITE ANALYSIS

The site is located in the West-loop of Chicago. It’s situated along the Kennedy Expressway near the Fulton Food Market. Traffic mainly comes from Downtown Chicago on West Randolph Street and exits from West Washington Boulevard. These two streets, along with North Halsted street, bound the perimeter of the site. Pedestrians access the site from North Halsted street, however the access is interrupted by the existing brewery on the northeast corner of the site. The project is oriented to maximize the visibility of the project in it’s surroundings, as well as to maintain a scale consistent to the commercial surroundings.

6

Site Analysis | The site has two main corners to activate on multiple scales.

Massing | The program was broken down into two towers with offaxis orientations to minimize visual disconnect to the city and the “wall� effect.

Podium Level | The parking is located on the south half of the site to maximize both vehicular and pedestrian circulation.

Programmatic Breakdown | The hotel tower is located on the northeast corner of the site to maximize street visibility.

Concept diagrams | Though perforations in the section of the project, the spatial organization transitions from horizontal to vertical.

Four floors are grouped into a “house” which house a series of amenity programs.

Two types of the “house” stack on each other to create a vertically connected building.

Connective Activity Experience | Through the relocation of amenity program into each “house�, the traditional horizontal living experience is replaced with a vertical one that encourages chance encounters.

Connective Activity | The project proposes a range of spaces that fosters chance meetings, spaces that have the possibility to create narratives outside of a single floor.

In addition, this frame acts as a horizontal louver to minimize direct sun in the summer and maximize heat gain in the winter. All amenity spaces are treated with the same enclosure to minimize energy consumption.

27

Work Space Section| Each amenity space has a covered balcony to view the West Loop area or Chicago Skyline. The cantilevered slabs utilize thermal breaks to prevent thermal bridging in the cold climate.

Amenity Space Enclosure Material Specifications

PV Panel System (Residential)

PV Panel System (Hotel)

Amenity Enclosure Each amenity space is framed by an 8’-0� cantilever on the top and bottom in order to create a horizontal louver. This shading prevents direct sun in the summer months and allows for heat gain during the winter to lower the energy usage of the building.

Looking at the building overall, the amenity spaces cover approximately, 20% of the total skin area. This means that about 20% of the building is utilizing passive cooling and heating throughout the year, lowering the energy usage for both the amenity spaces and the corridor.

To further this approach, the top surface of each amenity frame will have a system of PV Panel film attached to it to produce more energy. The goal of this is to highlight the spaces visually and environmentally, showing that this concept can help in a variety of different areas.

PV Panels (Film) | On the top of each amenity space, there will be a 1/8” PV film to maintain a sleek profile without obstructing/ distracting from the view to the city. This system is also flexible for installation in irregular locations so the overall surface area can be maximized.
