‘Let's make a roof where we can see the sunset and the Grand Canal.’——when the site was first surveyed in the spring of 2020, these simple words sent a beautiful vision of Bache community center at the beginning of the design. Located on the old street of Bache in Wujiang, Suzhou, just a ten-minute walk from the canal, the community center is actually the first in a series of micro-renewals of the old street. The main motivation for the micro-renewal of the street was the upcoming completion of the future campus of Soochow University across the canal, and the leader proposed to turn Bache Street into an Academy Town, expecting the future students to become a new force in the street and bring new opportunities for the renewal of the street.
With such expectations, the small community center, as a public activity space, becomes a key vehicle for the integration of the old and the new, and it is no exaggeration to say that a small building takes on a big mission. We often joked later that this is a house with ambition. The Floating Living Room Originally developed from a small town on the banks of the Grand Canal, Bache experienced rapid convergence and development during the Ming and Qing Dynasties, becoming a street in the administrative district of Wujiang District, Suzhou.
The Old Street is the core hinterland of Bache Street, which is also the location of the early market town.Therefore,the buildings in the Old Street are of different ages, including wooden structures and stone bridges of the Qing Dynasty that have been preserved to this day, as well as new buildings built at the end of the last century, with a mix of housing styles and materials, typical of a Jiangnan town.Although it is located in Wujiang,the affluent Land of Fish and Rice,only the elderly and children can be seen on weekdays.While most young people have gone out to make a living.The old street is in urgent need of vitality and renewal.Meanwhile,the introduction of the future campus of Soochow University across the canal brings the possibility of renewal and iteration. As with a large number of small towns, Bache Street belongs to a high-density residential settlement.It can not help but feel cramped and narrow everywhere.
Also,because of the issue of housing ownership and construction land index, the final location of the community center is precisely in the heart of the old street.A dilapidated school building must be demolished and a new parlor built.This undoubtedly adds to the difficulties of design and construction. Faced with such a dilemma, the first idea that came to mind at that time was to make the house float.Using the ground floor elevation as a strategy to make the house lightly off the ground, so that people who come here will no longer be wrapped in the confines of the alleyway, but will experience a sense of openness and permeability.
In order to make the elevated space as open and unconstrained as possible, a steel frame structure was chosen to achieve a large span, and a column was removed from the central part in consultation with the structural department to give the elevated space a ‘column-free’ feel. However, it is also because of the choice of steel structure, to the already difficult construction conditions brought a new challenge.The large lifting equipment for lifting steel components could not enter the construction site through the narrow alleyway.Also,several decrepit houses had to be demolished to make way for the construction.But in hindsight, this is more or less a blessing in disguise.The passage space formed by the open road is also considered to be the living room from the tightly wrapped release, breathable.
If the elevation is to breathe, then the sinking is to stay. The elevation of the elevated floor is 60cm lower than the surrounding ground, forming a both elevated and sinking courtyard.The steps around the courtyard are built with old bricks, which weaken the hardness of the sinking boundary and strengthen the sense of cohesion and affinity of the place.It avoids disrupting the view across the courtyard and creating a sense of tension at the bottom of the pit. In order to give the building a lighter floating feeling and reduce the oppressive feeling of the volume of the second floor overhead, a 5cm‘small neck’was set at the intersection of the column and the roof of the elevated floor, which looks like a shock absorber.
Although it is only a visual blindfold, this small design will really make the building overhead look lighter. The stairwell on the second floor is similarly recreated, with the galvanized steel plate at the bottom disconnected from the ground by 15 centimeters, and the beam in the center of the stairway hidden by the steel plate, so that the stairway looks like a slowly descending boarding ladder, adding a sense of suspension to the volume of the second floor. When the community center was first opened, it coincided with a rare and sustained high temperature for decades.The breeze from the elevation and the wind effect of the atrium made the elevated sunken courtyard a perfect place for the residents of the old street to cool off.
The courtyard continues to bring life to the street as the elderly play with their children and choral performances are often held by community groups. Plant a ginkgo tree In the atrium of the elevated courtyard, a ginkgo tree was transplanted. The reason why a tree was planted here is, to say the least, just an emotional decision.We always felt that the house would be more alive with a tree. It took a lot of trouble to select the tree at that time because of the match of the tree and the house.Only to achieve the goal of ‘first floor to see the trunk of the tree, second floor to see the crown, the roof to see the top of the tree’.It’s also a good way to expand the depth of field in a small house.
Choosing a deciduous tree is also to expect the change of seasons to be distinctly perceived in such a small courtyard. After the house was completed, the subtle relationship between the straight tree trunk and the structural column of the overhead floor was also an unexpected surprise. The presence of the tree trunk gave the column a certain natural softness.For a while,it was a little unclear which was the tree trunk and which was the column. The second floor is the main interior space of the community center, mainly used for open functions such as reading, meeting, and exhibition, also a children's reading space on the third mezzanine.
In order to make the space flexible enough and adaptable to future use scenarios, the space is not clearly and strongly separated, and the only thing that can be strongly perceived is the ginkgo tree. The tree is stored in a glass box on the second floor, standing quietly in the atrium enclosed by the glass curtain wall. We used ginkgo to create an inward-looking landscape on the second floor, but of course did not give up the opportunity to dialogue with the external landscape. The two vertical windows with a height of 4.8 meters on the southwest façade of the community center create a guided outward-looking view, fully perceiving the view and state of the old street.
Rooftop looking over the canal The roof of the community center is a slight curl, both to form a harmonious and different way of dialogue with the common form of the old street's sloping roof, and to make the roof terrace experience more relaxing and natural. In fact, the perception of this curl starts from the interior space on the second floor. In order to make this perception clear and real, the form of the interior ceiling on the second floor does not smooth out the change in elevation of the roof, but follows the curve of the roof and raises a curve leisurely in the interior as well.
For the smoothness of this curve, we spent a lot of time solving the alignment of the bridges and ducts.The change in ceiling elevation also follows a small mezzanine on the northeast side, and creates a kind of confrontation and dialogue between the second floor and the mezzanine. The height of the roof was carefully measured during the design. The elevation of the main terrace was controlled within 10 meters, which is just high enough to cross the ridge of most of the houses in the old street and form a distant view, but not so high as to oppress the surrounding houses in terms of volume and block the sunlight.
However, the height of 10 meters is not enough to see the Grand Canal clearly, so we reinterpreted the form of tiger window on the roof and turned it into a secondary terrace that can be used for people.The height was raised to 13.5 meters, so that the view can easily cross the whole old street and the busy Grand Canal can be seen in the distance. Bache originated from the Grand Canal, which is the root of Bache. We hope that on this roof, people can feel the presence of the Grand Canal and see the roots of a canal town.
At the same time, we can also joyfully perceive on the rooftop that the future campus of Soochow University, which has been completed on the other side of the canal, will be the source of vitality for Bache Street as a future academic town. Standing on the roof of the community center, it is both a look back in search of our roots and a look ahead to open up the future.‘Where did Bache come from and where will it go?’, our follow-up question seems to have been answered.
