“Institutions are the means by which societies are regulated. Their quality and character are a reflection of a society’s values, and consequently the architecture of institutions has long been a rhetorical and contested subject. While the institutions of Thomas More’s Utopia were reasonable and in harmony with the inhabitants of his ideal society, in reality, institutions are often instruments of power that reflect and perpetuate the inequalities of less than ideal societies. The earliest institutional buildings were places of worship, like Stonehenge, the Acropolis, great monasteries and mosque complexes. In the nineteenth century imperial powers developed new institutional typologies - pris-ons, courthouses, hospitals and parliaments – buildings that expressed the organisational capacity of the state, as well as power over its dominion. Some, like Joseph Poelaert’s Palais de Justice in Brussels, collapsed into formal cacophony, under the rhetorical weight of Imperial representation. In the post war period the language of modernism was used to express the efficiency of contemporary institutions and the apparent open-ness of the social democratic state.

This semester we will design very large institutional buildings in Zurich. We will engage with the architectural tradition that such buildings hold, of complex ground plans and developed sections. We will challenge references from the past with regards to how a contemporary public building should respond to the surrounding city, and what a contemporary institution should express. We will also speculate on how one can make representational buildings today, when everything in society militates against us attempting to do so, when many societies consider institution to be a dirty word.” - the Adam Caruso Chair

We placed two axis onto the site, one bridging the Central Sta-tion and the traffic to Klingenpark and the quiet neighbourhood ; another one bridging the denser fabric of the district to the Sihl river. Due to the generosity of the parks around the area, we decided to place the public realm within our building. Along the Central Station-Klingenpark axis is a long hall where both the public and staff walk through. The staff distribute themselves into the passages around the hall which take them to the offices in the outer layers. We wanted it to be a forest with a filigrain wooden roof that hovers above.

We wanted the long hall to be the public-police interface. When designing this interface, we took the sectional drawing of Le Grand Theatre de Bordeaux as an inspiration for how we present the gigantic institution to the public of Zurich. What fascinates us is how beneath a perfectly constructed world is presented to the audience of the play, and what runs the theatre is concealed behind this thin ceiling. We found this relationship between the innerworkings of the theatre and its public perception interesting, but we also wonder - what if, this ceiling allows the spectator to look through the functional elements of the institution above.

The painting of the Westminster Hall gave us further inspiration on how the ceiling of our long hall can be designed. What we developed from it is a 2-layer wooden roof structure. The lower layer towards the public is an arch and above is a modification of a traditional pitched roof with a stepping down language. Between 2 layers are delicate filigrain elements that fill up the inbetween and supports the roof.

The roof structure sits on the floor slab of the fifth floor, where the load above goes into the concrete structure behind the facades, instead sitting on the ground heavily. Starting from the floor slab, there hangs a curtain from bronze tubes over the heavy load bearing concrete structure, which become thinner towards the ground, as a continuation of the filigrain roof struc-tion. As if lifting up the curtain of a play, the crowd is drawn into the rooms on the ground floor that serves the public.

Along the perpendicular axis, a corridor leads people to a loggia on the upper floor that overlooks the river and the city. The smooth arm next to the main body contains regular office rooms encloses a forest of tall slender trees within the headquarter to echo the artificial and constructed forest in the great hall.

My intention is to have a new building with a visible and prominent concrete frame and beam construction, so that the structural system governs the division of spaces and also the penetration of light into the heavy concrete shell, next to the existing school building.

The concrete frames are placed along the building in a longitu-dinal manner. The double concrete frames are evenly spaced by the 5.4x5.4m module. All the small modular rooms are placed on the upper floor, connected by a long corridor that runs through the slender volume. The 1m wide narrow spacing between the two concrete frames becomes light wells through which light enters the larger rooms below.

The existing school is wrapped around by the long slender volume, thus creating a new passage that leads up the slope between the old and the new building and it is continuous with the central courtyard of the school. The end of the volume hides subtly behind the school to maintain the continuity of the old and new in terms of circulation flow and also view from the street.

Within the volume, there are three breaks from the rigid system. They are the multi-storey atrium spaces in which the vertical modes of circulation that connects different levels are placed. Also the breaks serve to connect the existing pathways on the topography by allowing the paths to cut through the building perpendicularly.

While all the smaller modules are on the same level, the spa-cious rooms below are stepped, descending the slope with a one storey height difference between each.

The volume is extended till it reaches the street to where the entrance hall greets the road, thereby asserting prominence and a greater relevance in the area.

BALCONIES - EXTENSIONS OF LIVING SPACE

In the site, I found that some of the facades have such depth that the spaces it creates have the quality of rooms – exten-sions of the internal living spaces.

I introduced vertical and horizontal slabs on the new façade to create pockets of spaces that can either function as a win-dowsill or a balcony depending on the height of the horizontal platforms in relation to the height of the windows on the facade. The vertical divisions act as a space divider to inform the outside of the internal arrangement of rooms and also to provide controlled connectivity between rooms and privacy between apartments. Openings on the vertical divisions pro-vide visual and physical connection between the two platforms belonging to one apartment.

The existing building is a residential building with 6 apart-ments. I proposed to replace the pitched roof with another storey on top to test out more variations in the new façade addition. Some of the windows are enlarged to have the dimensions of a door so that the interior can be continuous with the balconies. On top of that the order is imposed on the pattern of the windows since the existing arrangement is rather unclear. Each side of the building is divided into 4 equal parts with a row of openings on each part.

VIEW OF BALCONY FROM INSIDE VIEW OF WINDOWSILL FROM INSIDE VIEW OF BALCONY FROM INSIDE BALCONY

There are a few parameters to play with in terms of the com-position of openings on the façade.

I) The openings have two lengths – 2.3m and 1.5m which generates 2 combinations for each apartment –1.5m/1.5m and 2.3m/1.5m

II) There are two positions for the 1.5m long openings – in the centre or flush to the edge.

III) There are 2 types of connections between the 2 hori-zontal platforms within one apartment – visual connection and physical connection. Some of the platforms on the ground floor have no connections at all since it is almost level to the road.

Based on these 3 simple parameters, a range of typologies are generated. The rule of assigning the types are the apartments on the lower floors are less exposed to outside, so balconies are not assigned to the ground floor. On the top level there are more engagement with the outside.

The new façade acts as a buffer between the external environ-ment and the internal living spaces, a lively community social scene attached on the façade. It is merely a thin skin that wraps around the content of the building.

DILEMMA!

SECTIONAL ANALYSIS OF YAU TONG

MASSING

On one side of the harbour is the remnants of industrial activities in the 40s to 60s; on the other side is the quiet Lei Yue Mun village which has been transformed to a seafood paradise in the 70s, which has little relevance to the evolution of the village.

At the present, the municipal building plays the role of a communal gathering space, standing in between the newly developed prestigious residential blocks near the industrial area and the Lei Yue Mun village, which is currently under a state of stagnation.

However, the 13 storey high and out of scale mu-nicipal building fails to serve the local community and the flock of tourist brought in by the Seafood Paradise in LYM.

I believe what leads to its failure is the limited and rather inappropriate set of programmes and its self-absorbed and unwelcoming stance on the surrounding urban fabric.

I believe what is needed in Yau Tong is a mat-like infrastructure spreaded across the inner harbour addressing both the needs of locals and tourist.

Its building surfaces should actively engage with the pedestrians, whether on foot or on bicycle.

Instead of one single homogenous block, vertically divided units will respond to the specific programme needs.

THE UNIVERSITY OF HONG KONG2012 YEAR 1 SPRING SEMESTER DESIGN STUDIO/ JOHN LIN“VILLAGE HOUSE”INTERVENTION IN COURTYARD HOUSES IN CONGHA, GUANGDONG

I was first given the verb “to tie” from Richard Serra’s list of words. I experimented with various materials, mostly concrete, to bring the word into a physical form.

Then I interpreted the word again as an essential element of a house, specifically the courtyard houses in a rural village in China. The courtyard condition and the spaces around it interested me most. Courtyards has long been a living and gathering space in Chinese families.

I further experimented with the traditional pitched roofs and created spaces above the roofs.

In my design project, I introduced new elements into vernacular Chinese houses to come up with a comtemporary way of living in the village.
