The view of a park is very rare among such densed city in ROAD made good HK. The design JAFFE use of such site strengthness and create nice full height facade towards the park. Such design also connects the outter O and inner side of T R AD R A H K the LORbuilding.

VIEW

S U NLIGHT PERFOR M ANCE Such design can increase the maximum conntact with sunlight within the densed city. This can improve the overall performance of the building and appoarch sustainablity.

THE site strategy of this project is to fully utilize the advantages of a class C site. One of a corner is facing to a open greenary area - the Sothorn Playground. Not only can this opened area provide a longer view but also allow more sun light to get into the building. So, to make use of corner area to get sunlight and views is the main strategy.

CORNER OFFICE Corner office provide best view and daylight effect. It can al so be exempted from GFA in such a way. By maximizing the numbedr of corner offices, the layout provide higher flexiblity in terms of tenant customized layout of office.

Core

Site Strategy and concept diagram sustainable design of the building must coorperate with the best THE landscape. As the community is lack of such open space, the landscape design can improve the aesthetic of the community and welcome people to come around the building.

The landscape could provide more space for worker and the community. Enhancing the belongingness of the worker towards the community can boost their productivity and moral.

The refuge floor provide a new gathering place for the workers more than just a empty floor. The design can also reduce the heat gain of the building. They can gather, chat or even rest there. It would be a great place to chill out from work

TRI-EA

The form of the building starts from a regular square divided into 4 parts. Core is located at the back of the Hennessy Road. The other 3 block are the office functional spaces. Since they are in different orientations, so their facade design are designed individually. Horizontal shading louvers are introduced in the South faรงade -and vertical louvers are treated in the East faรงade. As for the SouthEast corner, it is face to the Southern playground, which is the most attractive view. In order not to disturb the view, louver are not articulated but instead tinted glass with different color are used and designed with an interlocking pattern. This can not only prevent heat gain and lower the lighting effect from the sun, but also enhance the atmosphere and creates a dramatic effect. The clear plane would increase the view from the interior. By rearranging the blocks, a significant block appeared facing the junction of the street, giving first impression of the building to citizens. The employees can also have an uplifted mood towards the junction where the stadium stands.

REFLECTIVE JOURNAL To start with, I feel confused at the beginning because building regulation is totally a new term for me. The governmental document is very difficult to understand. Therefore, the first studio problems and lectures really help me a lots. For example, when I searching the height limitation part, I got the data wrong, and fortunately, my tutor corrected me and guided me how to find the relevant government document. So that I can acquire the correct one and presented it on the presentation. As for the lectures, the lecturer is a part-time tutor and working in the architectural field, so that his working experience help us to know more how the regulation apply in real practice. Also, he explained the term clearly such as ‘dead end travel distance’ so that we can understand the term correctly. Moreover, the Seminars section have many invited guest to held talk to us, the different insight of them help me to explode building regulation and façade design at a different angle deeply. With the help of attaining studio class and lecture, I can independently to follow the building regulation in my own design. It is hard to kick off at the beginning, but I tried to calculate the area of life, staircases and other services room to form a core first, and then to design other office space. However, to design the whole floor plate is very difficult, because many of the factors are interrelated and complicated. For instance, the area is limited to ‘dead end travel distance’ and the provision of water closet is related to the number of occupancy etc. So I have to design very carefully and precisely. To assess my performance in problem cases, I am less aggressive in the group discussion than before. The reason behind is that when the opinion of different group mates is diverse, I would not insist my standpoint and follow others in order to prevent conflict. However, when I reflect it now, I think diverse opinions is important because we can learn from others and we should determine which is correct and wrong critically. And this practice can train up our group skills and communication technique. Moreover, I should more active to participate in class such as answer and raise questions. To consider my strengths, I am good at group skills because I willing to help my group mate when they seek help. Moreover, I like to discuss with my group mates such as what improvement we can do and to know their working process. So that we can learn from and support each other. For the areas of improvement, I am not very good at information searching. For example, my classmates can find many useful websites and books. I am weak in this area but my data analysis skills is rather good. Therefore, I would like to improve this area by reading more books and know more reference example such as overseas and local cases by different architects.
