SHERATON

N WENLING HOTEL

sheraton wenling hotel /woods bagot project description /

start from attending a competition in Wenling, Zhejiang, China, held by Wenling Intime Hotel Development Co.,Ltd, Woods Bagot has developed this multi-award winning mixeduse project in their Shanghai office including a 5-star hotel, a seviced apartment tower as well as restaurants, ballrooms and other function spaces. when I was assigned to this project, it is already in Design Development stage and I worked with the project for three months. I was mostly doing the remodels of the podium in according to design changing advices from consultants (such as the facade panel, skylights, the pod, structure arrangement and so on). I also helped doing some renders of design options, perspective sections, colour coding and some 2D documentation detailings.

383 la trobe street /architectus project description /

383 la trobe street is a mixed use Melbourne project designed by Ateliers Jean Nouvel (AJN) in cooperate with Architectus. This project is next to the heritage Royal Melbourne Mint and consists a five-star hotel, luxury apartments and retail shops.

Architectus is the executive architect of this project. My participation in this project includes feasibility studies, Revit modelling, levelling as well as early stage preparation for town planning documentation. One of the most important aspect of this project in early stage is to deal with the change of topography in the site.

Moreover, how to create a hall way connecting La Trobe street and the back laneway which is planned to be a Melbourne style retail lane, as well as entrances for hotel, apartment and car park according to the topography change.

I was in the part of managing the change of levels and making AJN’s design feasible.

paradox /competition project brief /

The competition asks designers to design a cultural architecture with certain programs with the theme "in between"

concept /

What is "in between"? There are "extremes" and then there is "in between". We understand "in between" as a contradiction state that is neither one extreme nor the other, and at the same time, it is both. The existence of "in between" breaks the dualism view of the world and leads a new direction for understanding the universe.

In architecture, "in between" can exist in different types of spaces: inside-outside, up-down, open-close, existnonexist...... The creation of "PARADOX" is based on such an understanding of co-existance of contradictories in space.

The introduction of the courtyard brought the spaces that is both inside and outside; the pulled-up space is created for looking downwards (amphitheatre), the pushed-down space is aiming for using for going up (ramp); the multifunction exhibition area open to the public has a sense of enclosure with concrete walls, while the restaurant for private function has a sense of openness with transparent glass facades. Moreover, we also recognized some potential spaces (existnonexist), including environmental exhibition zone in courtyard, outdoor cafe area and rooftop outdoor dining area, for fulfilling the lost functional areas. The design of this building broke through the understanding of spaces, created a paradox in space and thus expressed our impression of "in between".

siteless /individual work project brief /

“siteless� is an urban development project of Shanghai. the site located in Xuhui District’s west river side. the studio requires students to make a form generation process for one part of the site and spread this process to the whole site. The development of generation process focuses on the major building of the site.

concept /

this building design is generated from a simulation of liquid flow. What I found interesting about the process is that by controlling the viscosity and flowing speed, intriguing form with twists and folds appears. I have chosen to have two towers for this building because when I have two liquid simulation filling the site at the same time, they squeeze each other and produce much more interesting podium. Moreover, it is good for later stage where I can separate different programs into differen towers and preventing negative interactions between each program.

program /

the basic setting of building program is to have retail stores located in the podium, with 6 meters height each floor, commercial office area located in the high tower, with 4 meters height each floor and residential area in the lower tower, with 3.5 meters height each floor. I have also introduced two inside gardens to the building towers to allow people to get in touch with nature in this concrete jungle and make this building a much more human oriented design. Furthermore, I have also designed pubs and restaurants in the inside gardens to attract people visiting this part of this building and thus increase the practicability of this program. Some inside voids have been designed to fit different programs and avoid not usable areas. For example, large atrium has been placed in the residential tower but not in the office tower because in residential area the middle area with no direct sun light is useless for placing a residential unit, while the office tower needs maximum net lettable area.

3. Introduce three entrance points for the shopping mall and one entrance for each tower

1. Identify the ground floor area in order to design the circulation pattern

4. Introduce vertical circulation elements for the shopping mall area

2. Offset the edges to create areas for retail stores and form the circulation pattern

5. Predict the most visited area and introduce two anchor stores to maximize the visiting rate of other shops

circulation /

for circulation, I have first placed a core for each tower, allowing vertical transportation, than along the cores and the voids inside the podium, I designed a smooth circulation pattern for the shopping area. Three points where the pattern is most close to the building edge have been decided to be the entrances. However, I thought that residential area and the office tower should also have their own entrances to avoid entrances overcrowded and people get confused. After adding walls around the cores to create separate entrances for different programs, I also added vertical circulations including lifts, stairs and escalators for the retail area. Moreover, after connecting three entrances of the shopping area and identified the most visited space, I have added two anchor stores far away from the most visited area to maximize the visiting amount for the other shops.

skin /

for the skin, I choose to use triangular panels to preserve the smoothness of the liquid form and thus preserve the interesting points of the form. Two different types of panels are used in the skin: clear glass to introduce sunlight and titanium panel to reduce heat transfer.

Using this form generation for the master plan has produced satisfactory results that have similarities yet different from each other. Some green areas have been planned along the buildings and green roofs are also used for most of the buildings to make the overall design more environmental friendly.

WIRRAWAY CENTR

wirraway central /individual work project brief /

Located in Port Melbourne, VIC, the site is currently one side facing a residential zone (Williamstown road), one side next to JL Murphy reserve and two sides facing an industrial zone (Salmon Street, Plummer Street). However, in the future planning, the surrounding industrial zone will be turn into a commercial area. As for the design of Wirraway central, a large mixed used space containing a shopping mall, office area, community space as well as an underground train station.

design concept /

The initial idea is to introduce curve to the boxy area, make Wirraway central, one of the most important building in future development, to stand out from the crowd. In site analysis, it is found that the site and its surrounding areas are very flat, which actually gave me the idea of creating a landscape like building to increase the attractiveness of the space.

program /

The major three programs (commercial office, retail, community space) were allocated in the site in respond to the site surroundings. After a modification of shape in according to circulation creation, a large public square was also introduced to the site. City public square is usually a great place for people to hang out, and make it a sunken square gives the flat site an interesting level change.

sustainable design /

SECTION AA

1. Green roof was featured for all building roofs in the site to reduced the impact of urbanization.

2. The design promotes natural lighting over artificial lights. The glass facades can bring natural lighting to the interior. Even the sunken square behind the large office block will be able to get natural sunlight. The two sun path analysis diagrams displays the days with the lowest and highest sun path over the year and show the sunlight angle from 8 am to 5 pm on these two days. It can be seen that even when the sun is on the lowest path, the sunken square can get 8 hours of direct sunlight, not even mention when the sun is on the highest path.

3. As the summer in Melbounre can get very hot, all buildings are designed to have double glazing skin to increase the insulation level.

Moreover, some glass panels on the facade facing north (in the office block) will be replaced by solar panels. All solar energy will be collected and transferred to the mechanical floor in the basement and be used for the office. There are overall 350 solar panels, distributed according to a solar radiation analysis (the brighter the colour, the heavier the radiation, thus more solar panels).

option 1

revolutionary urbanism /group work project brief /

predict the future urban development in Shanghai and try to solve an urban problem related to the rapid population growth through a revolutionary urban planning.

The project is more of a conceptual design of how urban planning can be.

design concept /

as the population growing fast in Shanghai, an increasing number of residents is needed. The popularity of inner city for commercial uses caused the insanely high purchasing fee of accommodations in the inner city that is only affordable to few in China. Therefore, the majority people are forced to live outside the inner city and caused the decreasing number of population in the inner city. As a result, many newly built apartments are left empty without many people using them and the inner city has became a “ghost town�.

To solve this issue, the number of accommodations available in the limited land needs to be increased, and better living conditions should be provided. Three different concepts have come up: 1. reclaiming lands from commercial buildings; 2. new developed cheap accommodations co-existing with commercial buildings; 3. vertically building courtyards and maximize the use of space.

The design has imported the rules of cellular automata to allow spaces of comfort between residences while keep the number of accommodations available as high as possible.

option 3

REVOLUT

design description /

option 1: invading This option is more of a symbolic expression. The idea is using residential blocks to invade significant commercial landmark like Shanghai World Financial Centre.

Video presentation: https://vimeo.com/49918170 https://vimeo.com/49918171 option 2: co-existing town Using existing high rise buildings to produce influence patterns and develop residential town according to the patterns.

Video presentation: https://vimeo.com/49918173 https://vimeo.com/49918959 Option 3: flipper courtyard (main) Flip normal residential courtyard blocks and make them develop vertically. In this way, the same number of residents living in a normal courtyard could use the vertical spaces in the city rather than the horizontal spaces. More accommodations could be built in the limited urban area and prevented the urbanization going further towards the rural areas. Furthermore, the flipped courtyard shape provided a common outdoor space in each block unit and giving the highly populated tower a good living condition. It also made space for wind to go through and prevented the tower taking too much wind load when it goes too high.

OTARY MECHANISM

rotary mechanism /individual work project brief /

this project is a car show room design for Barlow Motors. It requires the space for displaying cars, a car service room, offices for staffs, additional 300 car parking spaces for surrounding office buildings and a single apartment for Barlow. The site is loceted in 20-28 Latrobe Street, Melbourne.

concept /

the concept of this design for Barlow Motors is “Rotary Mechanism�. It is primarily inspired by Wankel Engine, a type of engine commonly used in cars. In this design, a stimulation of how the engine rotates has been down and has been applied to both floor designs and the facades. Basically, the whole building is like driven by a rotary engine.

design description /

this building has nine floors including basements. The core part of the building, which is the Car Showroom, has been located on the La Trobe Street side. In the showroom, a large atrium in the middle rotates from ground floor to the fifth floor. And for circulation, ramps rotate along the atrium connect all floors.

The facades of the building facing La Trobe Street, Mackenzie Street and Grant Lane rotates along the triangles (representatives of the Wankel Engine core). The box form gives the overall design a rigid form that is very modern and mechanical.

For customers, the main entrance is on La Trobe Street. People can enjoy a cup of coffee in the Cafe or looking for their dream cars. If they need car services, driving down to the car service area from La Trobe Street and they can be well served.

For car parking, users enter from Mackenzie Street, drive up or down to different car parking floors by using a two-way ramp.

They can also enter the showroom through a hall way after parking their cars.

For employers of Barlow Motors as well as Barlow himself, private access is on Grant Lane. Moreover, lift and stairs are accessible for all users of the building on all floor.

The large empty roof of the car parking area is a space for Barlow to develop himself. He can put a swimming pool or grow a garden there.

queen elizabeth college /individual work project brief /

this is an adaptive reuse project dealing with an abandoned heritage site in Melbourne. It requires the designer to give a new function to the existing site, most focusing on the building 8, which was originally a chapel, and one other building of choice.

design concept /

to make this abandoned heritage site re-attract people to visit and use, I thought about making some interesting new additions to these heritage buildings and give these old buildings a modern look while remaining the beauty of the heritage group.

design description /

the site of this project, located in Carlton, Melbourne, was originally Queen Elizabeth Centre, a maternal and child health hospital specifically developed for women's refuge complex in 19th century. After its abandonment, part of the historical building group have been demolished and new apartments have been built on the northern part of the site. As it is located in a residential zone and most of the remaining buildings were built for the purpose of living, it is best to develop the remaining site as a residential area. With a growing number of overseas students coming to Melbourne, finding a good, comfortable and affordable accommodation near university becomes very hard.

Currently, there are already several residential colleges in the university campus, however, they are comparatively expensive for most students. This site is next to the University of Melbourne, which gives advantages for it to be developed into a small residential college affordable for students. In my proposal, building 5, 6a, 10b, 11, 12 will be developed into dorm rooms with kitchen, toilet facilities in each of these buildings. This gives an approximate total area of 1166 m2 for residence, about 58 dorm rooms.

NEW ADDITIONS STUDENT DORMS COMMUNITY LIBRARY COLLEGE STUDYING/ENTERTAINING ROOM

COLLEGE GYM TENNIS COURT GRASS BUSH AS PRIVATE SEPARATOR

Building 6b will be demolished in order to get more lighting in 6a and ensure all dorms have windows. Building 7 will be developed into a small gym for students with a tennis court next to it while building 10a will be the main entrance of the residential college with common studying/entertaining rooms. Building 8, which was formally the chapel, will be transformed into a community library, return to the public to emphasis its social significance. During the travelling, I learnt that local chapels are not just for religious use, they are also social gathering spaces for local communities. They bring community members more close to each other. And church is also a place that educates the public in ancient societies. It would be appropriate to change the chapel to a community library which is also a place where community members can meet and receive knowledge. Moreover, with information technology developed rapidly, less paper book stores are available in Melbourne now and this library will provide a chance for people in surrounding area to do some real reading instead of facing screens all day. However, building 8 is only about 63 m2 and lack of natural lighting. Therefore, a new addition of 40 m2 with large glass area for natural lighting is made to be the reading room and a second level is added to increase the bookshelf area. The form of the addition is a modification of the chapel based on the study of presidents as well as making openings for lighting.

Most glass areas are on the south side to avoid direct sunlight which is not good for reading. All additions have new structures to support them and the cladding will be red weathering steel as what was used for Australian Pavilion’s facade in Shanghai Expo. This gives the new addition a very Australian looking and makes the new addition easy to be distinguished from the old structure.

This addition idea has also been introduced to some other parts of the site to make connections between buildings and add more function spaces to those buildings. In the development of building 6a, the addition filled the gap between 6a and building 5, making a corridor and a common rest room. In the alteration of the interior of the old building, the cross axis is remained in the plan with the main corridor widened to make it more comfortable. The corner room next to the addition is made the toilet and shower because that room cannot receive natural lighting. The window openings along west and east wall of the building, which are from 1950s, have been modified to make every dorm room a window. New windows will be arched in memory of the original windows from 19th century. All the chimneys and fireplaces from 1950s are removed to make space more efficient and make new window openings possible.

The residential college area will be fenced with brick walls to separate it from the street. Nevertheless, the area around building 8 and building 8 itself is shared by the public and the college, therefore, this area will be a public and private transfer zone where bushes are introduced to be private separators instead of solid walls.

autonomous architecture /individual work+group work

project brief /

this is an experimental thesis project explores on how robotic technology can be used in architecture.

design concept /

the design focused on the research topic of robotic architecture reconfiguration, basically using robots to construct architecture, then use sensors to sense the environmental change and then reconfigure the build structure in according to the changes.

design description /

the site of this project is in Lincoln Square in Melbourne University, the tetrahedron modules will be aggregated with a large robot with a sensor scanning the site to determine obstacles in order for the aggregation to avoid them. After the aggregation is done, another sensor will do the sun analysis and produce a heat diagram. Small robots with threads will climb up on the aggregation, weaving patterns according to the heat diagram. The sun light sensor will scan the aggregation three times a day, morning, noon and afternoon, if heating situation changes, the small robots will climb up on the aggregation again, collect the threads and re-weaving accordingly.

PARA-SPECIES

para-species /group work design brief /

the brief requires a gateway on the Prince Highway in Victoria, Australia, at the part where people driving out from city of Werribe and entering the CBD of Melbourne. The following display is only for the experiment part.

design concept /

this design is experimental and aims for learning from the nature. As the nature generates complex life form from simple cells, the design uses parametric tool with a series of math functions to simulate this process and created a group of ‘para-species’ from simple straight lines.

design description /

the inital design from the left side is a slide show of a choosen parametric life form’s life circle (death to rebirth).

As we overlapped the patterns, an illusional 3D parametric life form has been born and become a more complex life form. It is a indication of change and development of a city and the

metaphor of evolution goes to the growing of human society as well.

Moreover the pattern generated is inspired by the aboriginal art from Werribe city and can reflect the aboriginal culture of Australia.

In consider of how to place the virtual species into real life world with real construction, a modification of the original design has been done.

The “para-species� have evolved through another technique from 2D to 3D life form as it has been shown on the right. The 2D pattern became an illusion and the 3D form became real. A simpler pattern has also been chosen from the “para-species group in order to reduce the number of different construction elements needed in real construction.
