In contemporary architecture and urban design, there is great emphasis on creating flexible open plan spaces. Expressions like multi-use or multi-purpose are often used to further describe this ambition. But the term ‘flexibility’ itself often implies ‘uncertainty’. What exactly does flexibility or multi-purpose mean? It is a paradox between randomness and order.

Randomness can be seen as the flexibility toward the possibility given to design. Randomness is acknowledgement of chaotic condition which is given while design purpose is usually acknowledgement of order which is a goal. Hence, randomness can’t always be random, certain aspects of such contradictory elements must be controlled with relevant methods.

Expressions like multi-use or multi-purpose are often used to further describe this ambition. But the term ‘flexibility’ itself often implies ‘uncertainty’. What exactly does flexibility or multi-purpose mean? It is a paradox between randomness and order.

Randomness is acknowledgement of chaotic condition which is given while design purpose is usually acknowledgement of order which is a goal. Hence, randomness can’t always be random, certain aspects of such contradictory elements must be controlled with relevant methods.

context & background

The randomness nature of street vendors, juxtaposed paradoxically with the act upon normalizing the main streets from the discomfort caused by street vendors themselves, calls upon the idea of Centralized Street Vendor. Centralized street vendors can be a new destination for people to make transactions and gather in the area. This purpose is mainly inhibited by the lack of shaded area at the most part of the site.

This idea tries to also open-up the possibility for the neighbourhood to have a recreational open space which they lack. Recreation in urban open space may include active recreation such as organized sports and individual exercise or passive recreation, which may simply entail being in the open space. Time spent in an urban open space for recreation offers a reprieve from the urban environment.

An area or environment must be balanced, well ordered but no less enjoyment. Play is a range of voluntary, intrinsically motivated activities normally associated with recreational pleasure and enjoyment. Less serious and outside the ordinary structure of behaviour. Stressful daily life needs activity to release the tension and activity needs place. The place takes its importance as an agent of a healthy environment maker.

idea

Sentra PKL Tambaksari, an informal market-typology located in Tambaksari, Surabaya is going to be the design case. The site is located near a soccer stadium where it was considered as the biggest soccer stadium in Surabaya. Its size definitely makes it a landmark. As a landmark, it must bring the opportunity for the public to gather and to enjoy the place. In fact, the stadium area is becoming desolate by time. There are no active events at noon and at night (fig. 1) there are only a few street vendors selling around the stadium. To prevent this acute desolation and gain the importance of the stadium area, there is a need for a trigger to revitalize the area.

Narrow street is one of the characteristics of Tambaksari area, worth to note is that narrow Street gives more intimacy among the people as good as the passenger with the skin of the building. Therefore, Narrow Street embodies the persistent expression and people in the local area, Kampong area. Crowded neighbourhood is also one of the characteristics of the surrounding. Since its density occupies a lot of spaces, it lessens the possibility to enable urban open space. The existing PKL ensures safety of customers, limited flow of the road as far as environmental hygiene issues. Another major problem is the chosen site is not located at the main street and doesn’t have any visible signs approaching the site. Problem three, PKL itself is traditionally organic or not centered as it has intended. This habit can be unique as the identity of PKL itself, besides becoming a challenge for the design.

design method

Requirements such as raising the quality of living within the area, emphasizing on uniqueness of PKL itself onto the site and the shape of design itself must be recognizable enough to be a unique sign of the area. First and main observed event is a transaction in the PKL area. Thus, this transaction demands shelter to offer conformity. Shelter can be made by various materials; since it is using concrete material, this also gives possibility to put another activity onto the concrete slab.

Further observation on the environment is less amount of public space. The space itself is occupied by housing and the street Events happen on the street dominated by traffic and at the same time pedestrian way. While the street is going to be quiet by the vehicles, some kids often use it as a playing ground. Despite its safety issue, this event gives the exact premise of open space need in the environment. Combining the possibility of another shelter usage and open space need as playing ground is the immediate response to the requirements.

The overall design method is using a very pragmatic approach according to the parameters provided by the requirement from the site and activities. The Force-Based Framework (Plowright, 2014) are used to underlying the rational thought behind the design method for this project. Parametric method is used as a tool to input the requirement of the site and activities as a parameter to generate and drive geometric shape. Both digital and analogue/manual parameters were used by the project. Utilizing both hand drawn sketch and computer software to compose the geometric shape (fig. 2) .

#Program Sketch

Sketching is the first step to visualize the thought and context. This sketch is evolving following the context and later seeing the possibility to generate the concept. The real condition is simplified to its essence subjects and events which happened on the site. There are some considerations for initial sketch (fig. 3) :

1. Transaction

PKL main activity is transaction. There are some minimal physical attributes for this kind of transaction. The most important element is the display. On this display many kinds of goods have been put on. Then the communication and agreement between buyer and seller happen. One display to another is various. So, it gives specific characteristics and nuances.

2. Continuum – Transaction

Transaction itself can be temporary or persisted depending on the needs of buyer and supply of the seller. Since the existing PKL occurs very often, it can be concluded towards persistence rather than temporary. The continuum course of action in transactions later creates more permanent physical attributes and occurrences. The basic effort is putting a roof to give a sign of stability and convenience of behaviour.

3. Adding Value

The roof itself essentially is a slab which has two possibilities, it serves as a roof / a shelter and as a floor – a ground. For the upper floor. It simultaneously provides two requirements with only one solution. Since the upper floor will act as the space for a playground for the kids around the neighbourhood. It will provide an added value to the otherwise no-kids environment street vendor.

4. Synthesize

Since the roof itself has a possibility to be a ground for another purpose and play activity needs place. Therefore, it will make sense to put that ground as a playing activity. Sketch is not in the exact dimension of the site, so it leads to draw the concept onto the site modelling. Site modelling is intentionally excluded from its surrounding to make it easier to evaluate.

#Design

The form of the ground floor follows the shape of the site. Triangle-like shape gives dynamic expression of each side (fig. 4) . Since it is very stable in its correlation amid the side, therefore, to maximizing the square meters, such area is used completely except the area by the offset needed for circulation. Second floor is determined by projecting the ground floor (fig. 5) . This method has many visual disadvantages. The length of the second floor slab is spanned at almost 70 meter long. It is considered bulky, massive, gigantic in size compared to surrounding. There is also structural ineffectiveness with this kind of shape, the action to trim the length of the second floor is needed to compensate for such a problem.

Parameters used to trim the gigantic floor shape are generated by the vegetation occupancy with the consideration of aesthetical, convenience, and accessibility. The result of trimming is the new shape of a single flat floor. This new shape has many advantages such as flexibility, unique, and intriguing both visually and physically (fig. 6) . Circulation within this building between ground floor and upper floor flows seamlessly with the provided ramp. Seamless circulation brings convenience to passengers for both circulation between the floors and enjoying the building as recreational activity.

Structural consequence will be a major challenge of this new shape. Organic like slab shapes have more complex column arrangement since the ground floor is almost an exact triangle. The differences of shape between the floors create a significant impact for every endeavour. Using the regular grid will generate rigid boundaries, especially for the beam and column, and not compatible enough with the organic like shape of the second floor, since it will be too inefficient for the dimension of the beam considering its consistency versus the irregular shape of the floor.

#Solution for the Challenge of the New Shape

The column placement is the key action to determine the structural grid of the beam (fig. 7) . Since the main idea is to give notion of less perceived boundary while the second floor is also an irregular shape, then proposing a random grid of structure for column placement is a reasonable decision. Random grid is generated by parametric approach, using the same imaginary radius and intersection of the radius. The result is random placement of columns with the same distance to one and another.

Figure 3 shows the technique of column placement using nodes and its radius to intersect one to another. In this script maximum and minimum value is included. This value is determined by structural consideration. Figure 8 shows the column placement, the nodes. The nodes can be connected through the script and this connection later is going to be the triangulation beam.

result

Random placement of columns (fig. 9) is causing the use of triangulation methods for the position of each beam which connects the columns (fig. 10) Triangulation gives more chance to accommodate the peripheral modification and therefore there is no problem to modify the shape of the ground floor. Since the irregularity is the main idea of this design (fig. 11)

As the irregular columns are enabled, there will be endless configuration of street vendor placement. Irregular and various placements will strongly sense by the accommodation of orientation or size which varies to one and another street vendor. A ramp connects the ground floor with the upper floor. A ramp itself will create more fluent and inclusive access for users. Despite its simplicity it will visually contrast with its surroundings. The design will appear simple, seems effortless, lean, but effective, irregular, accommodates randomness and attractive at the same time (fig. 12) .

Figure 13 , Figure 14 , Figure 15 shows some of the examples of the possibilities of space configurations.
