COLUMBIA UNIVERSITY GSAPP | SPRING 2020 CRITICS: ENRIQUE WALKER TYPE: OFFICE & PUBLIC SPCAE TEAM: KYUCHAN KWAK, YUKON KIM, HELENA URDANETA, CHENYAN ZHOU SITE: 1 CHOME-11-1 TSUKIJI, CHUO CITY, TOKYO, JAPN
Dentsu Headquarters by Kenzo Tange was originally envisioned to generate a condition in which the city would happen below as programs float above ground. We aim to bring back this public quality. Now, services, mobility and structure will engage with the public. Flexibility, light and movement become the new language.

The First Scheme
The Second Scheme
The Final Built Dentsu
It is important to note that this building is a byproduct from Tange’s Proposal for the expansion of the city of Tokyo to float above the waters of Tokyo Bay
Providing a free plan in which the city would happen below as the buildings float above ground To free the area these large scale constructions would be elevated by vertical structures
is less ambitious. Although it still has an elevated ground, it serves no public purpose

How to Double its Surface...
8
For doubling, we push the original program above the original structure is now void for Public
9
The Movement From our movement cores, users will be able to only access the auditorium from the top part of building and from the ground By celebrating our movement component Users are invited to transit the air square The building is now open to the public
10
The Conversation It is a conversation between our new building and dentsu Two buildings collide and the formal aspects are the result of the interplay of its functions and components
11
The Ground While maintaining the grid of our original Dentsu. The column spans allow for extensive public circulation on the ground level.
12
The Market The building is open to the public The city is now connected through escalators to a double height market space in two floors. Planned to complement fish markets on the Tsukiji area. Two areas on each floor and no walls.
13
The Garden Above the market space A main congregation garden space is created Enough Daylight and high ceilings create an optimal environment for trees to grow.
14
The Auditorium By increasing the gap between this space and our auditorium Users can move below our floating box Dentsu’s columns will not obstruct the auditorium spaces As the box is suspended from the upper steel truss
15
The Escalator Will connect it to our lobby
16
The Lobby The moment where our two buildings collide Users are able to experience both systems
17
Two Steel Towers Will support the office part of the building It will consists of two elevator shafts Along with Services and Egress stairs
18
Technical Detail The steel towers are covered with concrete panels embracing the materiality of original Dentsu concrete structure, and providing a Servant and served quality
19
The Office Is continuously connected amongst floors
20
The Roof Top Truss Is the key structural component that will maintain everything up

ASSOCIATIVE SPACE IN DISSOCIATIVE URRBAN FRAME T O W A R D S A N E W E R B R U TA L I S M COLUMBIA UNIVERSITY GSAPP | SUMMER 2020 CRITICS: EMMETT ZEIFMAN TEAM: KYUCHAN KWAK & YUKON KIM TYPE: LIVING & WORKING 22 SITE: RIGHT NEXT TO HIGH LINE

Our idea is to create two different worlds in one space: a combined live/work area. The living area— the outer world—is private, visually connected to the city, and receives natural light. The work area—the inner world—is public and connects to the city. As an extension of the street, the inner world functions as a commercial space. A “mechanic belt” combine s these two different worlds into one space, serving as a threshold between the inner world and the outer world.

Living Spaces By hiding all the infrastructure inside the mechanical belt, only pure living spaces remain. Private and independent grid space

Workspaces It is a conversation between a public lamp and stairs type workspaces Interior spaces facing vertical expansion of the HIgh Line

Typical Floor Plan
This project is a dormitory for graduate students for Pratt Institute. Since graduate students are more likely to have their own families than undergraduates, they are less likely to socialize. Therefore, our goal was to make the most effective space layout, including the necessary facilities and excluding social spaces. We designed most of the units as two-bedroom apartments for families based on a fair layout and size. The equally sized units contribute to a uniform facade, and by placing an open staircase at the corner, it appears as two different buildings. Also, by creating wall like columns on the first floor, the two facades feel as though they are floating in the air. The narrow sidewalk for the public is also effectively enlarged.
