Four study areas were chosen in this report because they appeared to embody characteristics that were typical of many other neighborhoods in the city. In each of these areas a single block was chosen for data collection that was representative of the wider neighborhood. A wide range of measures was taken in an attempt to record the essential attributes of each block objectively and for comparison with the other study blocks. These measures included many of standard tools of urban planning and urban design: population density, building coverage, parking ratios, street widths; as well as a few unusual measures: frontage per entrance, historic population estimate, median parcel size.
Because the study collected a wide range of data points it is possible to see how the differences and similarities of the neighborhoods shows up in the numbers. These are all dense, urban neighborhoods, and as such they do have much in common. However each is composed of a different type of buildings, the physical attributes of which give the neighborhood much of its character. Can those attributes be measured in order to understand the why the qualitative differences one perceives when visiting are so clear?
Many of the measures are not helpful for distinguishing between neighborhoods. Some vary little, some move arbitrarily, some provide us with context without revealing anything about the study block itself. Some of the quantitative measures show little difference between the neighborhoods.
There were a few measures that showed important differences between the neighborhoods related to the form of the neighborhoods themselves. Several of these show a clear direction of change: number of parcels, median parcel size, building count, parking ratio and vehicle traffic mode. These measures all move in one direction with building age from Indre By to Sluseholmen. This seems to reflect the centralization of development decision-making and resources into fewer hands over time as well as the rise of automobile ownership.
A few other measures of the form of the neighborhood showed something a little different. Street-level shop count, building coverage, block size, courtyard size - these measures all move in a certain direction in parrallel with building age, until the Sluseholmen study block, where the direction is reversed. Sluseholmen was designed to recreate some of the feel of a historic neighborhood, so it makes sense that this is reflected in the measurements. Clearly, whether intentionally or not they’ve recreated a few of these aspects.
Are these measurements really getting at the most important differences between these places? Building coverage is a crude measure, and the success street-level shops are dependent on the qualities of a neighborhood at least as much as they help to shape it. The grain size of a place - which shows up in block size and courtyard size, is clearly important, and in this degree Sluseholmen shows real progress. Still, we hardly know anything about a place if we just know that it has small blocks. What are the qualities that these measures are hinting at, and what are they obscuring?
Further Research
Several dynamics revealed themselves during the course of the research which seemed to have strong effects on the quality of different neighborhoods depending on the type of building that predominated. The effect of these dynamics on the built form of different cities and neighborhoods could provide rich areas for further study.:
1. Centralization/decentralization of planning, design, construction and ownership
The number of decision-makers at each level of the creation and maintenance of residential buildings changes drastically over the range of neighborhoods studied. In the case of the Welfare Era building there was an exceptional degree of centralization. This tended to have the effect of maximizing those values prioritized by the bureaucracy, apartment size, integration with infrastructure, and efficiency of construction.
In the case of the Golden Era townhouse individual building owners made decisions about the design of their buildings, but their decisions were based on a common framework of vernacular design as well as design-plans made available by the court architects. The street and parcel grid were essentially inherited from medieval times, and construction outfits would have been small groups of craftsmen and laborers. The devolution of decision-making authority to more actors and to traditional practices seems to create a more complex built landscape, while centralized planning can provide structure and coherence. The situation in which many actors are making decisions within an overall strong frame work seems to result in the most successful neighborhoods.
2. Orientation outwards/inwards
A marked difference between the 19th century neighborhoods and the 20th-21st century neighborhoods lies in the orientation of their buildings. In the Golden Era and Industrial Era building types the building is clearly oriented towards the street to the public: street-facades are more ornate, living-rooms face the street, while courtyards were cluttered with refuse, human waste, and poorer-quality buildings and plain facades.
Welfare Era buildings take a sharp swing in the opposite direction. Ostentation is abandoned in favor fairness and elevation of human dignity in the form of improved living conditions for all. These buildings turn inwards, focused on modern dwelling quarters and spacious courtyards. Livability Era buildings generally maintain this orientation away from the street, although ostentation in the form of architectural avant-gardism has made a comeback. These buildings are designed for residents to take pleasure in their homes, not to go out into society searching for something.
This shift in orientation is preserved in the built landscape of the neighborhoods composed of these different types. It seems no accident that the most lively nightlife zones are located in neighborhoods composed of elements built to engage with society.
3. Specialization of function and class
There is a strong chronological trend towards increasing specialization in the building types described. The Golden Era type is vertically stratified by class, with servants living in attics and wealthy families on the first floor. Shopkeepers and pub-keepers are operating out of the cellars and light industry or animal husbandry is taking place in the courtyard. The Industrial Era type generally maintains these arrangements, though industry is starting to move to specialized districts and the poor are more often constrained to the crowded back buildings in the courtyard.
Welfare Era buildings by contrast are enormously specialized by function and class. They are made of identical dwelling units with identical prices. They are built to provide the best possible housing and this is nearly the only thing they do. While the Livability type makes concessions to the mixing of uses, they are nearly as specialized as the Welfare Era type especially in terms of socio-economic class, as these buildings rarely contain subsidized units.
4. Purpose of creation
Buildings of each type were created for different purposes, the effects which were expressed in their design and location. Golden Era townhouses were built by wealthy families to establish their stake in the city. The Industrial Era type was built to turn a profit. The Welfare Era type was built to advance society (and sometimes to develop voting constituencies in suburban jurisdictions). The Livability Era type was built both to turn a profit for developers and to strengthen the city financially.
The purposes behind the creation of each other neighborhoods profiled is revealing too. Like the Golden Era bourgeois, the hippies of Christiania sought to establish their stake in the city. Nyboder was built to strengthen the power of the state, while the urban renewal projects in Norrebro were an attempt by the state to change an existing neighborhood for its own good. City planners and citizens should be conscious of the motives behind their planning and building projects as these will likely be permanently expressed in the form of the built environment they create.
