Traffic Flow

Fig 23.Traffic Flow in urban form of Afri-Cola

The traffic in the urban form of Afri-Cola house is fast flowing thought most of the roads. The highway and the major roads have fast moving traffic. The old Roman road being more feasible for the pedestrians thus has a slow traffic flow.

Moreover, the roads on the left of the highway have slower traffic. Whereas the tertiary roads on the right have a free fast traffic flow.

The buildings along the highway were mostly built after the second world war when the international style dominates around the world, that the buildings basically followed functionalism with limited decorations on the facade.

The introduction of the highway did change the shapes of the courtyard of the urban blocks within the targeted area, in the old Roman district, the shapes of the courtyards are most irregular due to the accumulation of buildings from different era, while the urban blocks, newly developed after the construction of the highway, were planned with regular shapes of courtyards for more efficient uses, for example, as a parking lots for cars.

The sequence of the urban form is also shown in the road system of the targeted area, from radical road system in the old Roman district to the grid system that was developed after the second world war. Overall the road system is planned under the urban structure of Cologne, the ring system along The Rhein, that we can see the gird system is distorted slightly to fit the context.​

Fig 29. Map before war - 1885

After the war, the plots were sub-divided into smaller ones and the roads were made more defined. The port was converted into a park. The Roman road still stood as one of the main roads.

The railway line was extended and made wider, effectively changing the plot shape and size in the surrounding.

Fig 30. Map post war - 1950

The current situation in the area is a continuation of further division of blocks. The plots are divided into subplots with different typology of buildings.

The highway runs paralle to the Roman road through the block of Afri-Cola and divides the block above and below it into two different parts

differenciated with the sizes of the buildings in the map. The post war structures as seen above are seen in the form of small grains linked next to each other defining perfectly the shape of the block. Where as the modern and post modern designs of the buildings can be observed from a change in the size with larger plot size and are more often scattered rather than being continuous.

23

Mutation of the Urban Tissue

Fig 33. Urban grain in the area surrounding Afri-Cola

For the demonstration of how the postwar reconstruction mutated the urban tissue two streets in the study area were chosen: the Eigelstein street, which remains from the ancient Roman civilization, and the North-South Axis, whose year of construction is after the WWII, in the 1950s.

Three aspects of both streets were analysed: the volumes, the entrances, and the facades.

24

Volumes

Fig 34. Volumes of buildings in the urban form of Afri-Cola

As a consequence of a wider road, the buildings on the North-South Axis are higher and wider than those located in the ancient Roman road.

The Eigelstein street is characterized by small volumes, whose width clearly reflects the variety of the plots. Only one block of this street contains more than 10 types of buildings (or 10 different volumes), while in the same block, there are only three buildings facing the Turiner Street. On one hand, the volumes on the Eigelstein street are juxtaposed, resembling a puzzle. The buildings also tend to have “new” volumes added on the backyards. On the other hand, volumes on Turiner street are more massive and tend to have a “final shape”. There is virtually no room for minor interventions that would somehow “bother” the original form.

25

Entrances

Fig 35. Entrances of buildings on the Roman road and the highway

The car as a defining element of the relationship between the street and the architecture provided new types of accesses to the buildings. Instead of a door directly opened to the street, some buildings on the Turiner street have parking areas as a transition space for the entrance. It is remarkable that for those cases, the parking entrance does not directly face the Turiner street but is placed on secondary roads, which are perpendicular to the highway. Thus, the traffic may not be interrupted or slowed by stopping vehicles.

26

Entrances

The protagonist is the car rather than the pedestrians as it occurs in the Roman Road. The lack of openings in the ground floor, which on the contrary are much more frequent on the Eigelstein street, also reveals that Turiner street is not a place to stay but to pass by.

Conclusion

By taking Afri-cola building as an intervention,

​

three different scales of researches explicitly show the mutations between architecture and urban context that somehow explain how the city was formed meanwhile how the architecture were designed. The urban block of the chosen building is relatively simple but unique compared to the urban tissue around that the big advertisement board gives the urban block an identity and reacts to the highway in front of. The urban tissue around Afri-cola haus is very diverse since it is cut into two parts by the newly built highway after the second world war, that one parts of the urban tissue belongs to the old Roman historical district while the other part were mainly built after the second world war and has modernist style. The research of the urban form can be seen as a regional study of the Cologne city that is not just focus around the building but scale up to the whole city development, which included wider research aspects. Four proposals as the reflection of the previous researches, we found out that the discontinuity from the Roman historical district to the river side for bikes might be a possibility to improve the integration of the urban context, therefore based on four different themes, all the proposals are aim to provide a better cycling environment in the city.
