01 INVASION & MERGING

2015 Tsinghua University Open Studio — Socialist Slabs Instructor: Li Hu, Luo Ren, Ye Qing Site area: 6000m2 Location: Beijing, China Collaborator: Ge Sihang, Ding Xiaohan Contribution: Concept 30%, Analysis 70%, Phisycal Model 50%, Techinical drawing 80%, Rendering 40%

Beijing has been expanding at an incredible rate in the last decade, taking up too much room while the city has become fragmented and dull. This project is a renovation of an old social dwelling in central urban area of Beijing. It focus on tackling the conflicts between high demand for residence and lack of public space in the neighborhood . In this project, we try to explore the relationship between private living unit and public activity space. The original dwelling is largely closed. The residents are seperated from each other and isolated from the city. With an open and sharing attitude and new public programs, this project aims to become a renovation prototype for simmilar old dwellings in the central urban area.


CONT Location

Its convenient location and complete facilities in the area has made the apartments extremely valuable for people like office workers, young parents with children.

Similar slabs were built as social housing around Beijing in the 1970s. By redesigning this building, we create a prototype for future renovation for the similar ones.

Slabs around Beijing

Isolated Slab

The slab stands like a poker-faced giant in the center area of Beijing. With no program other than residence, the slab has little interaction with the surrounding urban area. The slab is a dead end of urban space.

Isolated Apartments

The building was divided into units, between which the only horizontal connections are corridors on every third floor. With little common space, the apartments and its residents are isolated from each other.


TEXT Chinese Housing Evolution

Social Housing in China has shown a dramatic evolution after the foundation of the Republic, mostly due to cultural revolution and economic development. Materials for living needs, like stoves and toilet, has been gradually individualized. A result of this major change is less interaction between neighbors. Communities are breaking into pieces.

Courtyard House: Common Space Ratio 65%

Tube-shaped Apartment: Common Space Ratio 45%

BEFORE 1940s: FAMILIAL

Modern Apartment: Common Space Ratio 20%

FROM 1940s TO 1980s: COLLECTIVISM

AFTER 1980s: INDIVIDUALISM

Failures in Modern Social Housing

As Le Corbusier envisioned, social housing should have explicit function areas, designed by architects from top-level. However, due to low in government fonding and self-sustainability, the buildings would fall in inevitable decay.

Failures to Meet Current Needs

The slab was designed and built only to tackle housing problems in the decade when most citizens were satisfied to have a roof over them. However, as the living standard has improved over the years, the slab becomes out of date. I want places to hang out with my friends. I want a playground!

These shared spaces pierce through the old building and grow in the new frame. As it perforate on the shell of the original slab, middle zone like terraces and garden is generated between private apartments and public space. As these volumes extend out of the east facade of the slab, they become a showcase, attracting urban citizens to use and generating more interaction between the complex and the city.

PROGRAM DISTRIBUTION

There are three major types of apartment groups, they are designed to suit different major groups of urban citizen.

These groups provides them the opportunity to enjoy themselves at home at a cost they could afford and communicate with their peer groups and those with common interest.

The frame structure create a vertical community. Slab residents and urban citizens could access the community easily, creating interaction among them.

02 OPEN CAMPUS GATE

2016 Tsinghua University Landscape and Urban Design Studio — New Campus Gate Instructor: Prof. Zhu Yufan, A/Prof. Liu Hailong Site area: 0.3km² Location: Beijing, China Collaborator: Yu Haowei, Jin Biru, Shi Yiyuan Contribution: Concept 40%, Analysis 50%, Rendering 50%, Technical Drawing 40%

University campus are usually largely separated from the city in China, while possessing public service facilities that are scarce to the city. As a new campus gate is to be built on southeast border of Tsinghua University, we consider it as a chance to make some changes. After studying the site area on city scale and regional scale, we redesign the road system in the area to adapt to the changes brought by the new campus gate. Sites like Tsinghua Art Museum, School of Fine Art, new transfer station attract huge crowds to the area, along with daily commuters. In this project, we try to organize these flows and circulations, integrate absent public programs into the landscape, share resouces for on and off campus user, creating an open campus gate.


City Road Grid The large campus breaks grid pattern of roads.

Current Road Status Low-efficiency roads leads to poor traffic condition.

Off-Campus Urban facilities are easier to access by the gate.

On-Campus On-campus facilities are within walking distance.

Planning Road A new plan for road system is proposed.

Combine Tracks and Roads Three barriers in front of the gate are combined.

Flow and Circulation Large crowds are diverted by their transportation.

Resource Sharing On and off campus people share the landscape.

PROGRAMS ON DIFFERENT LEVELS We design an underground system, connecting different blocks and facilities, and seek to restitch the neighborhood. The underground system includes a transfer system among buses and two metro lines, an underground entrance to the art museum, an on-campus parking garage, passageways connecting each street block and commercial and service facilities. Programs are distributed on different level. Indoor programs are placed in underground space. Aboveground space is left for landscape and outdoor activities.

03 WEAVING WOOD STRUCTURE

2017 Collegiate Timber Structure Design Invitation Tournament — Natatorium Design Instructor: A/Prof. Huang Weixin Site area: 7000m² Location: Nanjing, China Collaborator: Zhang Ruochen, Tong Hanshuang Contribution: Team Leader, Concept 70%, Analysis 40%, Rendering 50%, Physical Model 40%

In the design process of a natatorium, our major focus is the large span structure. The natatorium is located in a green field in a university at Nanjing. Wood, which is more environmental friendly than steel and concrete, is our first choice of material. Also, since the texture of wood is pleasing to eye and gives people a warm and mild feeling, we want to design a natatorium with magnificent exposed structure. Inspired by the research and design made by Frei Otto and Shigeru Ban, we create a weaving shell structure. The weaving grid is generated and optimized in computer. Plywood structure components could be prefabricated in factory precisely. After structure analysis and calculation, the sizes of the structure components are much smaller than the sizes of corresponding parts in ordinary frame structure.


WOOD STRUCTURE

Glulam has a better strength to weight ratio than steel. Modern glulam technology allows the manufacture of thick, wide and very long components, not just simple straight but curved elements too.

GRID PATTERN DEVELOPMENT

The ordinary triangle pattern has shape stability. However, due to the rods of three direction intersect at the same point, the joint at each intersection would be complicated.

By offsetting the rods, a mosaic grid pattern of hexagons and triangles are created. There are only two rods at each intersection. The joints would be much simpler.

When the structure becomes double-layered and weave through each other, the overall structural strength was largely promoted. The size of components are reduced.

04 SECTION GENERATOR

Computational Design Study Programmed in Processing 2017.10 Individual Work

Before the famous artist Piet Mondrian developed into rigorous abstraction of Neo-Plasticism in which he limited himself to straight, horizontal and vertical lines and basic primary colors, suppressing any sense of a subject, his early stages of artworks possess a feeling of space flow on the canvas. Paintings like Blue Facade(1914), Composition(1916), are similar to section cuts of buildings. When we look at these artworks, colors and lines directs our focus to travel on the canvas. If we look at evenly-distributed grids, we tend to lost our focus. It is similar to people's flow and circulation in a building. Guided by partitions and characteristics of the space, it is easier to find a destination, while in homogeneous space, people tend to get lost. In this project, I try to use generative algorithms to create compositional section cut drawings of a building. After generating process in computer, we human could make other interpretation, creating new partitions and connections.


REFERENCE STUDY

Composition and Architecture Composition of a painting directs our focus to travel on the canvas. If we look at evenly-distributed grids, we tend to lost our focus. It is similar to people’s flow and circulation in a building. Guided by partitions and characteristics of the space, it is easier to find a destination, while in homogeneous space, people tend to get lost. Extracts of Local Distance Benjamin Maus, Frederic Gmeiner, Thorsten Posselt

Colors and Size The relationship of colors in the painting would affects people’s feeling of the size. Piet Mondrian’s Composition with Red, Yellow and Blue is a perfect example. As shown on the left, the painting without color gives viewers almost same feeling of the size as the original one, while the size of the grid is altered.

Altered Painting without Color

Colors and Composition Colors of a painting decompose the geometries. In the painting Nude Descending a Staircase, variation in brightness and saturation of the color shows the movement of the nude women. In Rothko’s No.1, the black color is the only element in the composition of the painting.

INTERPRETATION USING ELEMENTS After the generation of basic sections in computer, the drawings need to be interpreted. Architectural elements,including terraces, balcony, tunnels, are extracted and new elements, including steps, stairs, ramps, could be added.

THREE DIMENTIONAL TRANSLATION When several generations of section cuts are extruded and stacked on one another, three dimensional space are generated. New connections and partitions that are parallel with the section cut direction are added.



SPIDER WEB 2015 Tsinghua University Architectural Computation Design Studio Instructor: A/Prof. Huang Weixin Site area: 400m2 Location: Beijing, China Individual Work

As landscape of the city has changed dramatically, the urban tissue of old Beijing has been largely eroded. In this computational design studio, we were required to conduct a research on a biological form, transform it into a prototype for architecture design. I choose to simulate tangled spider web, of which the forms vary according to the surrounding area, and install it into Beijing Hutong area, bringing vitality into traditional courtyard house district.
