The Stone
Design by Chen Sikai
ABOUT This project asks for a design in an open and natural space in Tampines area, Singapore. Diversity in the boundary conditions of the plot like the MRT station and different types of roads and pathways, the buildings that are framing the space, accessibility, close amenities, potential users, character of the different traffic roads, etc. will be taken into account to produce a building thoroughly connected to its close environment. I developed a personal approach to deal with an urban yet natural context, and explored strategies to arrange the required exterior and interior spaces within a consistent and relevant design, carefully inserted in the site. Hence, I came out will idea of “Stone�: The building will placed one the center of the site and attract guest from surrounding to the point, which like the mile stone of the site

The Void Forest Design by Chen Sikai
ABOUT Working on the scales of the city, the building and the individual unit the studio aims to understand the complex nature of urban contexts as places for habitation and the mutual potentials evolving between them. The studio project will develop innovative urban housing concepts for sustainable high-dense living and focus on themes like density, diversity and connectivity. The integration of building systems like load-bearing structure, services and building envelope will be treated as constitutive parts of design process. The site, Yishun, are located at the north area of Singapore, arrounded by the residential HDB and hence, need to link the design with the surrounding.

Tube House
Design by Chen Sikai/Cheryl Lim Jia Li/Low Wei An/Porndee Chua/Zhou Xinyi
ABOUT The Project site is located in Ho Chi Minh City, Vietnam.The house in Vietnam has the unique characters: long but narrow. Hence,it provides the chance for architects to design the special house like a tube. As the requirement, we need to design the ceiling, facde and the massing of the tube house with dimension of 4 meters width, 12 meters depth and 4 floors height. The house are required for natural ventilation and lights but prevent from the raining and direct sunlight during lunch hours. Hence, we come out with the idea of “across chessboard� for the facade and ceiling. It will allow the indirect sunlight to enter the house with the natural ventilation come into house. In the meanwhile, it will create the nice outlooking for the entire house as well. The project combined structure, computation and design studio work.
Concept Why Air Ventilation? We feel that in tropical Vietnam, heat is an endemic issue exacerbated by the crowded urban conditions and unaffordability of air conditioning to a major segment of the population. As such, we want to focus on naturally ventilating the building as a primary issue. Our Plot, P3, is ideally located for receiving wind (arrow) during the summer months.
With neighbouring buildings at close proxmity, we also wanted to focus on privacy as a secondary issue.
Hot air rises Cross ventilation Cool air rushes in Uniform cross ventilation
Sliding to drive ventilation
a. A smaller volume
b. Sliding to introduce voids
c. To achieve effective ventilation break the block before sliding
Concept Why Air Ventilation?
Due to long and narrow nature of the building, the size of void have to be carefully designed to maximize the functionality of the space
Facing out
Wind enter from the side to aid cross ventilation. Steel and glass panels have alternate arrangement. Opaque steel panels aid in protecting privacy. Use of glass panels allow light to enter.

Technical Drawing
The frame is patterned by N-shaped steel beams. These provides extra support for the load and also connects the inner and outer layers of panels together.
L hinge to attach the facade frame to side wall so as to provide structure support for the building
The reinforced concrete floor is not only load-bearing, but also integrated into the building structure to provide the support for the facade frame to hamper the frame structure from bending.
The tiling panels are divided into two layers and slightly offseted from each other: 1) outer layer: panels are transluscent enough to transmit light but not betray inside movement. 2) inner layer: panels are transparent to

TAKING FLIGHT(Jointed Shelter Frame)
Design by Chen Sikai/Low Wei An/Christyasto P.P/Lee Hyosoo
ABOUT The Project site is the school wide project. We are required to select one place in the university (Singapore University of Technology and Design,SUTD) campus area, then design and fabricate the structure for exhibition purpose. We come out with the design of the space frame structure by using the Grasshopper computation. And then we chose the 1 meter wooden rods to construct the frame out. As the team, we design the seat jointed pavillion frame and become one of the interesting exhibition frame in the campus.
Concept Design Concept Following the idea of letting 'imaginations take flight', we wanted to create a shelter that resemble the motion of taking flight. In addition to this, because our site is located at the midst of the planter areas, we took inspiration from the nature. Inspired by dandelion petals flying off to the air, the form of our structure intends to express the motion of taking off and reaching towards the sky. The shelter provides the users a space where users can reflect and ponder about their ideas while viewing the airplanes taking off Image source: bridgedesign.com
Structure Concept DIAGRAMMATIC FORM
SPACEFRAME
The original structural concept was to design a lightweight fabric structure, however, the single layered structure is prone to slack due to its weak structural properties. Furthermore, since our structure is placed outdoor, the structure needs to be strong enough to withstand the wind and rain loads. For a more stable structure, we designed a mesh frame that will provide more stability for the structure.
Grasshopper Coding
Form-finding The Grasshopper code generates a space frame that is made up of pyramid-shaped elements. From the spaceframe generated, we adjust the nodes to create the form that we intended.

layers, a sanctuary in Pulau Hantu
Design by Chen Sikai/Mok Junwei/Zhou Xinyi/Neo Xinhui
ABOUT In this project, we were tasked to design and develop construction specifications for a shelter on Pulau Hantu. The shelter must have the maximum dimensions of 3 m by 6 m by 9 m for overnight or short term stays for researchers, who carry out environmental observations on Pulau Hantu, and possibly find a daytime retreat for discussion and writing. My group explored the idea of utilising timber as the main material of the structure. We were also played with the idea of having many horizontal and vertical elements that which density affects the amount of light and wind from entering the pavilion.

Inside Out Chair
Design by Chen Sikai/Low Wei An/Lee Hyosoo/Christyasto P.P
ABOUT To create a complex geometrical form through combining simple angular elements. The main objective that we want to achieve is to design a chair that can transform its form depending on whether the chair is in use. When the chair is in use, it can be raised up into a 3-dimensional chair form, otherwise it can be collapsed and flatten into a 2-dimensional rectangular form which can be stored easily without taking much space.
Concept The chair is design to be used in a modern home setting. As homes in cities are getting smaller and smaller, there a need to design a furniture that can save space when it is not in use. Observing that furniture takes up most of the space in homes, we decided to design a chair that can be flatten when not in use and can be stored easily without taking too much space. Hence our design objective: a transformable chair that save space Through starting with a piece of rectangular wood, we explored different geometrical form by slicing the wood to identical rectangular strips. From the rectangular strips, we tried to fold each one of them at certain angles, then applied geometrical function to achieve different forms. We started from basic functions such as sine and cosine and went on to experiment more complicated functions.

Axonometric View
Front View
While exploring different geometrical possibilities with ‘V’ shaped structure, we intially experimented with the simplest function and form to observe whether the ‘V’ structures are stable enough to create a chair. To experiment this, we tried to make a miniscule chair using wood sticks that resemble the wooden strips. During the experiment, we have discovered that we had to add hook system for the actual product to prevent sliding when seated.

Final Iteration
Grasshopper karamba force loading simulating Materials for testing: Wood, Steel and Aluminium Loads to apply: 1kN/m 1.5kN/m 16kN/m Due to the self-weight of chair (gravity), when the loads are not applied, chair is undergoing certain stresses but these stresses are negligible (0.4%). The stresses surface at the back rest region and seat because of the beams cantilievering. The highest stresse is taken by the horizontal chair legs due to the supporting functions by the legs. For the safety purpose, safety factor (1.5 and 3) is applied to test the structure strength of chair and through testing, the maximum load for the chair is 16kN/m, which means the chair will be able to take three times loads than the expected loads. When the materials changed, the safety factor will change accordingly. (Steel: Maximum Load 29kN/m; Aluminium: Maximum Load:15kN/m) Steel
