a platform as public space how architecture can deal with the topography to create green space?

Arnaud BAAS AUSD - Architecture and Urban Space design

Abstract

Designing with the shadow is relevant specially in the southern countries like Portugal. A lot of public space are full of vegetation but what about the shadow when the leaves fall? This is where a platform should be useful because it can combine public space as in the common sens and also a shaded space below. So, this platform should be a hybrid because in our future world this kind of architecture should be a mainstream way of designing a building. Also, it is impossible to talk about hybrid without mentioning coexistence as a hybrid is a coexistence and vice versa.

For a coexistence design, the hybrid has to take into account the context to fit perfectly the needs of the area where it will be built. In Almada and Hjällbo, the topography is an important feature of the site. That is why the first big step is the mapping of inclination and shadow. The mapping’s datas have to make the design evident and relevant. To create a hybrid, the design process has always to start with this step. It will allow anchoring the projects on their construction sites.

AlmadaandHjällboreallyneedahybridintervention.

Those cities are like «islands» without any connections to others, so a hybrid architecture would dynamize them and bring life again there. In Almada, the project will invest the free spaces thanks to the demolition of the oil tanks. This could be the perfect place to attract and welcome people coming from Lisbon, on the other side of the river. In Hjällbo, the project will take place in the middle of the forest to create a new walkable connection between Hammarkullen and Hjällbo.

Also, investing the forest will allow the inhabitants to enjoy nature around them.

So, those projects have to be hybrid, deal with the Almada’s and Hjällbo’s context but also has to create kind of a landmark, a place where people want to meet each other and have fun. This place should also be mixeduse to concentrate most of the activities and services that people need and like in one place.

MAdrid

Description: Eurovillas, built in 1968, is located in a small municipality called Nuevo Baztán in the southeast of Madrid. It is kind of a young city (1709) composed of a small historic centre surrounded by modern housing estates development area like Eurovillas.

As you can see on the map on the left, This district is quite far from the Madrid’s city centre, therefore there is no real good connection between this area and Madrid with the public transportation. It was built during the 60’s so in a world of cars, it takes around 40 minutes by car to reach Madrid.

Furthermore, Eurovillas is like an island because it doesn’t have any connection with the existing city and has its own grid of streets. A project like this can work if you have enough diversity in the area but it isn’t here. Most of the dwellings are detached homes for the basic family: two parents and a child.

Everyone has his own private yard with a swimming pool and no one has a direct frontage onto the streets. But the good point is that there is a lot of facilities and services to create a feeling of community like a shopping mall, a big green area and a sport area. But as there isn’t any sidewalk, everyone moves in his own car without really talking each other. The project was really ambitious but the financial issues lead to some mistakes like the lack of sidewalks and landmarks. So it is more a drivable than walkable city.

Strenghts / Weaknesses: Almost all the facilities and Lack of sidewalks services that a community need The internal connectivity is Nopublictransportconnection easy thanks to the urban grid with the city centre There are some bicycle routes

Methodology:

First of all, concerning this assignment, we decided to delimitate our area of study for Almada. So we drew a rectangle that includes all the riverside front and a part of the seaside front. This area was split in three according to major axes, by this way all of us could work on each step rather than just only one.

First we differenced the urban structures in two kinds: on one hand the housing and on the other hand the rest of urban structures. Then we kept on differentiating those realms into several categories and we ended up having eight different urban structural units, listed below.

The housing type: detached and semi-detached houses, continuous row houses with built-up courtyards, and housing estates built after 1960.

The non-housing type: industrial areas, special estates, recreational areas, infrastructural and educational facilities.

As a criteria for the housing categories, we worked on the relation between built and unbuilt lands. For the nonhousing ones, the main focus was on the map and on the 3D model. This allowed us to see what kind of building they are.

Those categories will be shown thanks to transparent colored flat tint above the map. By this way, we can see why this area belongs that particular category.

Then we look into the border between each one of those urban structural units. In the text Morphological patterns of urban sprawl territories, Angelica I. Stan describe five kinds of mechanisms of urban growth towards sprawl: the fragmentation, the juxtaposition, the intercalation, the parasitization, and the randomisation.

To recognize what kind of mechanism occurred, it is important to pay attention to the shape of structural units represented before, but also to the relation each units have with one another. In this way we can clearly see what kind of bounders there are.

The graphic way to do so would be a line between each area that come into confrontation. There are different lines depending on the mechanism: from the straight line to the dotted one.

Finally the space forms. They are once again described in the text Morphological patterns of urban sprawl territories and divided into five types: the clusters, the tentacles, the enclaves, the borders, and the fringes.

For this step, it is crucial to look at the drawing that housings and roads are making. That way you can see what kind of space form a unit is. You also have to pay attention to potential natural or artificial element that would play the role of barrier for the development.

Each space form is represented by several hatches that go on top of the urban structures. At the end, every single one development type is unique. The fact to manage representing all the steps on one map allows to see every information and the diversity of each area.

Analysis:

By analyzing the map, we can clearly see that the city started to grow from the east to the west. Because the connexion with Lisbon is important for the city’s economy. It is also interesting to notice that the older part always expanded behind its industrial harbor and never tried to invest the waterfront with housing or services.

But when some tourist arrived, they decided to invest the west coast to build camping and some housing areas.

About the structural units, in the western part, the major activities are in the city center of Costa da Caparica and Trafaria. We can notice all the different housing typologies that live together in this side, however the detached houses and continuous row housing are predominating.

In addition, industrial infrastructures appear next to Trafaria in the north-coast. This leads to the mechanism of juxtaposition which brings incompatible functions close to each other in different scales. There is also a passive co-existence between segregated communities in the southwest where the development of small groups of housing near agriculture fields produces a lack of communication with nearby entities such as camping and social housings.

At the end of the principal axis of Almada (Highway A38) the density of dwellings decreases. This part has a great agricultural and ecological value. It is characterized by having a lot of farming fields and urban development sprawl. The beaches on the west-coast are another particularity of this part of the city together with the concentration of big recreational areas.

Also, by analyzing the different infrastructure, it looks evident that the Highway A38 divide the city in two parts because it stops most of the connections between the north and the south of the city.

In the northern part, we can notice that the construction of the university didn’t have any impact on the city’s urban structure yet. But the aim is probably to develop the northern part of the city because as the highway divide the territory in the middle, the student will probably live closer to the river and to the connexion with Lisbon.

In the southern part of the city, there is a concentration of detached and semi-detached houses. This Almada’s part is probably the first place where the city expanded.

Concerning the different mechanisms, globally, we can say that in the urban development there is not a lot of randomisation and parasitization probably because this is usually managed by an urban planner: By this way, there are no more space for randomisation and parasitization.

Furthermore, we can observe some examples of fragmentation in the northern urbanizations where there are a lack of collector roads and a lack of connectivity with a discontinuous urban fabric. Moreover, these places can’t expand as they are between the sea and the green areas. The northern urbanizations together with the industrial equipments can be defined as borders. Around the main axis, small dormitory communities appear surrounded by agricultural fields that take the forms of patches.

In conclusion, th western part of Almada has segregated urban developments that have been growing over time but haven’t been consolidated with all the necessary urban infrastructures and services.

There are still a lot of open spaces in Almada, but the city has to densify first its existing urban structure because most of the housing is detached or semi-detached.

Why this area for the platform ?

By investing this area, the platfarm would be able to use the waterfront, which is a big lack for Almada.

The inclination on this area is very interesting and diverse, from flat to almost 65° of inclination.

On this area, there is not a lot of shadow just during the sunset so it should be interesting to create some.

CHARACTER Is the design specific to the scheme?

As part of the million program it stands out with nice detailing. It is clearly defined by the classic million program planning.

1

Does the scheme exploit existing buildings, landscape or topography?

It is deliberately ignorant of existing buildings, topography and landscape

The existing topography was flattened out and the run of Lärjeån was changed during the construction of the area.

0

Does the scheme feel like a place with distinctive character?

The orientation and height of the bulidings and the modernist function separated planning gives this area a distinctive million program character. This is visible in fwWor example the skolspåret area.

1

Do the buildings and layout make it easy to find your way around?

Buildings are not oriented towards the street, making it difficult to recognize streets and perspectives and find your way.

Hjällbo was the first of the northern suburbs that were constructed in the 60’s and was considered a model for later million homes developments.

If the area was to be densified, attention could be put into clarifying streets and courtyards in order to create a more readable hierachy.

0

Are streets defined by a well-structured building layout?

Short ends of buildings are oriented to the streets. Planners were mpore focused on light and ideals of the green, rather than street structures.

STREETS, PARKING & PEDESTRIANS Hjälbo traffic situation is a good example of SCAFT planning ideals.

The stategy is largely critisized for causing segregation but does ensure green and carfree areas.

Does the building layout take priority over the streets and car parking, so that the highways do not dominate?

The area is splitted by the highway. At the same time the area itself is designed for the pedestrians

0,5

Orange indicates parking spaces. They occupy the street frontages to the main roads.

Many million program suburbs are now planning to build dwellings on top of parking spaces.

Is the car parking well integrated and situated so it supports the street scene?

No as there are located in the street frontage and in the public spaces

0

Both pedestrian paths and bike lanes are well developed within the area, but only connect over the highway in two points.

Are the streets pedestrian, cycle and vehicle friendly?

The pedestrian paths are priority inside the area and not close to big streets.

0,5 Map of bike lanes through the area.

Does the scheme integrate with existing streets, paths and surrounding development?

No. It is an almost isolated island cutted of by the infrastructure and the forest.

0

Are public spaces and pedestrian routes overlooked and do they feel safe?

Some of the public spaces are not overlooked by dwellings at all. The functions are highly seperated. We have not enough information about lighting

A densification strategy could be to strengthen the links between Hjällbo and surrounding areas. Development could take place along the connecting paths and streets through the forest in order to make these connection feel more safe.

DESIGN & CONSTRUCTION: Is public space well designed and does it have suitable management arrangements in place?

It is uncleared which spaces are public. The mall appears closed

0

Do the buildings exhibit architectural quality?

Part of the scheme is considered to be of high architectural quality. They were marketed as ideally beautiful, modern and clean at the time of construction. These houses make up a small portion of the entire scheme, which displays the drearyness and repetition associated with suburbs of the later 20th century.

0,5

Do internal spaces and layout allow for adaptation, conversion or extension?

As the buildings are constructed using a rigid prefab load bearing structure, the interior partitions can probably easily be changed. The area is not dense in terms of building footprint, and thus there is space for extention of the scheme.

We are not entirely sure if the construction methods for all buildings of the scheme - an answer for this would require more technical research.

1

Has the scheme made use of advances in construction or technology that enhance its performance, quality and attractiveness?

It was considered attractive and used innovative technology when it was built. Probably the architecture aged better than the ideals behind it.

1

Do buildings or spaces outperform statutory minima, such as building regulations?

They were designed based on research and regulations, and all perform according to swedish standard.
