AbstractIn this paper I will investigate spatial scale as one vital aspect that needs to be more
carefully addressed in discussions on sustainable urban forms. First, I discuss problems of
spatial scales in the light of recent urban transformations, focusing on the Malm-Lund
region. Second, I discuss the discourse of sustainable urban forms, pointing at some scale
related problems that need to be more carefully addressed .In the third, and main part of
the article, I discuss plans and projects of urban development in Malm, focusing and
elaborating on three tendencies of scale stabilisation: territorial, geometrical andhierarchical. Concluding, I suggest that if we want research on sustainable urban forms to
inform us on how to build better urban environments, we need to think of it is as a tool for
integrating issues and problems that formerly were specialised or sub-optimized,
counteracting splintering urbanism; one foundational issue of such an effort would be a
multi-scalar approach that does not handle scale as a pre-given entity.

1. Introduction
The idea of applying the concept of sustainable
development to that of urban and architectural
form has increasingly been addressed and
discussed by researchers, planners and architects
during the last decade. The issue of sustainable
urban form has, however, both in discourse and
practice, been a problematic one, leading to
different and contradictory results, e.g. in
discussions for and against the compact city (Frey
1999, Jenks & Dempsey 2005, Kaido 2005). The
progress of the field is often quite contradictoryand complex, but nevertheless implemented in
different guidelines and directives (Williams et. al.
2000).
One core issue is that of methodology. How do
we find and define sustainable urban forms?
How do we investigate the question? How should
we even pose the question? To actually judge
whether a certain urban form is sustainable or not,
does not seem to be an easy task. To some extent
the problem echoes the old modernistic dilemmaof function and form. Both problems are set up as
a relationship between cause and effect, between
urban form and outcome. I do not contest that
there could be some stable relationships between a
set of activities or relations agreed upon as
sustainable, and a certain urban structure. This
relationship is however not so easily generalized
in terms of such dichotomies as nature-culture,
object-subject or form/function (cf. Latour 1993).
In this paper I will investigate spatial scale asone vital aspect that needs to be more carefully
addressed if we are to talk about sustainable
urban forms. I will specifically look at the scales
at which different sustainable urban forms are
implemented and discussed (in research as well as
in planning). The argument of the paper is based
on the notion that urban forms participate in the
production of effects on different scales (they are
multi-scalar), and that these effects might vary
accordingly. If we want to discuss the meanings
and effects of built form, scale is thus an issue of
key importance. The paper uses the concept of
scale as related to urban form, taking its cue
primarily from urban morphology but indirectly
also from scale as discussed in a more eclectic
architectural discourse (by such diverse authors
as Rasmussen 1957, Gehl 1980, Boudon 1999,
Lawson 2001). Although the aspect of
architectural and spatial scale has been widely
discussed in architectural theory the actual
impacts of built environment as analysed through
different scales has rarely be studied (although see
Yaneva 2005). I will here use Caniggias and
MaffeisArchitectural Composition (being one of
the classics within the field of urban morphology)
to define scale as: different level of complexity
of the components internally arranged to construct
a whole (Caniggia & Maffei, 2001 (1979):245).
Although my field of interest is that of an urban
morphologist, I will use the perspective of actor-
network theory (Latour 2005), and regard spatial
scale as continuously produced by different
collectives (in, what can be called, an ontology of
becoming). The description of Caniggia & Maffei
thus suits me fine since, components is abstractenough to include actors (and actants) of different
sorts: social, material, political, etc.
My urban-morphology-perspective on spatial
scale differs from the scale analysis and theories
developed lately, largely within the field of
political geography (Marston 2000, Brenner 2001,
Swyngedow 2000, Randles & Dicken 2004,
Collinge 2005, to mention a few). Although I do
agree with some points made in this quite
heterogenic field of research: e.g. that scales arenot pre-given, but produced by human
interactions, social relations and political actions
I also think it is important to stress more heavily
that materialities, forms, shapes, artefacts, etc. of
different kind are indispensable co-producers of
such scales and scale-related effects. This, in turn,
often means that scalar outcomes are non-direct,
unintended and even unpredictable (cf. Randles &
Dicken 2004). Keeping this in mind, the politics
7/29/2019 Setting the ScSetting the Scale of Sustainable Urban Formale of Sustainable Urban Form

of space must be discussed not just by analysing
intentions and discourses, but also by taking the
issue of form and materiality more seriously.
The aim of the paper is to investigate research
and planning discourses on sustainable urban
form, posing the question: at what scales are these
sustainable urban forms discussed and
implemented? First, I give a short introduction to
the primary context of the paper: the region and
the expanding urban landscape,1 as well as the
discourse of sustainable urban forms. In the main
part of the article I look at Malm and some of the
UD projects planned there during the last decade
in order to discuss three tendencies of scale
stabilisation that seem to be reproduced in the
discourses and plans that I have analysed.
2. The scale of the urban
landscape
Although perhaps seldom addressed as a subject
of its own, scale has always been one of the main
issues of urbanity and urban form debate. The
French architect and theorist Phillippe Boudon
even regard it as the key concept of an
autonomous architectural science, a field that he
refered to as architecturology (Boudon 1999, cf.Lundequist 1999). Today regional scale seems to
be an issue of growing importance in a much
larger context than that of architectural research.
The transformation of towns and cities to urban
regional landscapes has been going on all through
the 20th century, starting with the trends of
suburbanization, garden cities, etc., in the
beginning of the century. Lewis Mumford
1 Sustainability and scale have been addressed at muchlarger scales at other places, e.g. discussing howpolitical issues can be set at a global scale,depoliticiszing or repudiating the activites taking placeat a national or local scale (Baeten 2000). Although theeffects of the built environment indeed might take us toa global level (and a network context) I constrainmyself in this paper to a regional context (See Law &Mol 2002, on different spatialites and contexts from anANT-related perspective). See also Marcotullio &McGranahan 2007 on scaling urban environmentalchallenges on both local and global levels.
commented in the 1930s seeing how motor ways
and railroads enabled a non-hierarchical region
where: no single centre will, like the metropolis
of old, become the focal point of all regional
advantages: on the contrary the whole region
becomes open for settlement (Mumford 2005
(1937), p. 96). Although this transformation of the
urban structure was noted early on, it did not
become thoroughly conceptualised until the
1990s (partly due to a vast number of influential
hierarchical conceptualizations, e.g. Christallers
central place theory, The Chicago School ring
model, The Athens-charter zoning systems,
NewmansDefensible Space, SCAFT). Today,
however, we are witnessing a conceptual
production discussing these urban transformations
at the scale of the region in terms such as e.g.
Zwischenstadt(Sieverts 2003),Netzstadt(Oswald
& Baccinin 2003), citta diffusa (Boeri 2003),
lurbanisme des reseaux (Dupuy 1991), the
network city (Abrechts & Mandelbaum 2005), the
regional city (Calthorpe & Fulton 2001), and
splintering urbanism (Graham & Marvin 1998).
These conceptualizations, and to some extent also
mappings (Boeri 2003, Abrams & Hall 2005) of
urban landscapes, networks and nebulae implythat regional scale is rapidly becoming an issue of
growing importance (and where Boeri et. al. 2003,
even plays with the idea of seeing the whole of
Europe as an urban region). New regional
developments, infrastructures and politics also
affect and involve the everyday life. People
commute more and longer, tourism is an ever-
growing industry, and new institutions are
established at new scale levels. In the end, this
does of course also affect spatial planning, that hasto come to terms with a new context where
distance has more to do with time than kilometres
and social process such as urbanisation,
greenbelts, investments, centres etc, seem to be
scaled up (this planning shift has sometimes been
refered to as shift to network planning, Hajer &
Zonneweld 2000, Albrechts & Mandelbaum 2005,
cf. Healy 2005). Planning and strategies for
development are still very much treated as

territorial issues set within the frames of a hard-
edged container, (Healy 2005: 151), not fully
dealing with the fact that a lot of relations,
problems and phenomena are more and more
enacted on new and multiple scales. Even though
the scale of the urban landscape is increasingly
conceptualized and discussed by researchers as an
empirical phenomenon, it has not yet reached its
potential, one could argue, in more normative
texts, in planning visions and in new ideas on how
to build. To some extent this is also a result of
with how planning practice is organized with
responsibilities hierarchically divided at different
levels of scales, often focused on intra-territorial
issues and different fields of interest, such as an
organization might lead to the optimisation of
isolated elements, areas or aspects, but could have
harder to cope with the multiple relations of the
urban landscapes (cf. Healy 2005).
3. Sustainable urban form in
research
What is sustainable architecture, sustainable urban
design or form? InAchieving Sustainable Urban
Form (2000), Williams et. al. conclude that
sustainable urban forms are characterized bycompactness (in various forms), mix of uses and
interconnected street layouts, supported by strong
public transport networks, environmental controls
and high standards of urban management
(Williams et. al. p. 355.). Compactness and
concentration of the built environment to transit
nodes are two of the most common statements
(and can for example also be seen in Swedish
reports such as SOU 1997:35 and Boverket
Vison 2009, cf. Westford 1999, 2004).
In research on sustainable urban forms (Jabareen
2006, Frey 1999, anthologies such as Jenks et al
1996, Williams et al 2000, Jenks & Dempsey
2005) there seem to be some kind of agreement on
the themes that are relevant (summarised above).
But what kind of forms are sustainable? Looking
at the discourse from the perspective of
(morphological) spatial scale, three things come to
mind.
First, and perhaps most striking, is the lack of
differentiation when it comes to the notion of
form. The key themes for sustainable urban form
is often represented as e.g. a formless statistical
number of density, number of uses, or distances
(one-dimensional form), discussing some wanted
effects characterised as sustainable, rather than the
urban forms that could accommodate for them.
Using Kevin Lynchs definition of urban form as:
the spatial pattern of the large, inert, permanent
physical objects in a city (Lynch in Jabareen
2006:39), one can note that the notion of pattern
or shape is seldom addressed at all in a more
concrete manner. The differentiation of form is
often quite weak, listing some ideal models (such
as Jabareen listing four idealised models) rather
than discussing different morphological aspects.
Discourse on sustainable urban form surprisingly
seldom takes its cue from urban morphology,
though there are of course exceptions (notably
Scoffman & Marat-Mendes 2000, and to some
extent also e.g. Westford 2004 & Frey 1999). To
illustrate the problem of neglecting form, we can
take the example of density. Density does ofcourse fluctuate with scale, changing borders and
perimeters of the place also changes density. Even
within the same borders the same density or floor
space ratio could very well represent totally
different building typologies and ways of life (cf.
Jenks & Dempsey 2005). For diagrams on how
different building types relate to number of
storeys, floor space index, and density ratio, see
Rdberg & Johansson (1997:75), and Bergshauser
Pont & Haupt (2007).Second, although scale is addressed, it is often
done in a quite simplistic and hierarchical manner,
where scales are set by administrative borders or
typological area classifications. Furthermore, most
discussions seem to focus either at the scale of the
city (e.g. the compact city) or at a
neighbourhood scale. Some look at the region, in
discussion of e.g. polycentric versus monocentric
models (Frey 1999, Okabe 2005). However,
7/29/2019 Setting the ScSetting the Scale of Sustainable Urban Formale of Sustainable Urban Form
5/10
Setting the Scale of Sustainable Urban Form 5(10)
changing scales, jumping surging scaling up and
down, lies in the very heart of the design process.
(Yaneva 2005). This kind of scaling (done in
architectural practice) often take a more
phenomenological approach, producing scales
from the perspective of lived space: how does this
particular building affect the skyline, the life on
the street, the view from the park, the light in the
rooms of the building next door, etc. Just setting
the height or the width of the building could
immediately affect all of these scales and of
course many more. Sadly, this activity of scaling
is not yet much verbalized or conceptualized in
discourse. In what networks is this building (or
parts of the building) an actor/actant? What roles
does it play in different scales? Mixed uses within
a city district does not per se mean that people
walk or cycle that has to do with other things
like urban design, spatial structure, but also with
scale. At what scale are these activities mixed, at
the level of the building, the street, the block, the
district, is the mix to some extent repeated on
several streets within the district or the located to
one street, or a mall?
Third, there seem to be a tendency of favouring
certain aspects, such as density and mixed use,looking for a one-rule model. Whereas, e.g.
Jabareen, develops a matrix for the evaluation of
particular suggestions, one could argue for the
possibility of several futures and pathways (Guy
& Marvin 2000). The possibility of scaling
problems and solutions differently, together with a
diversity of social interest, etc. seem to suggest
that there could not be one optimal solution. Thus,
a discussion on sustainable urban form need to
take a more heuristic trail, addressing a pluralityof important issues and methods rather than
producing one-rule-models, one-liners or optimal
solutions.
4. Three tendencies of scale
stabilisation
In the following I suggest and discuss three
tendencies of scale stabilisation found in
sustainability planning and discourse. My
empirical material mainly consists of plans and
programs for Malm urban development during
the last decade. These tendencies are not to be
read as a critique toward the planning going on
but as a suggestion for issues that need to be
conceptualised and elaborated on further.
Malm is a Swedish municipality, working quite
consciously and ambitiously with aspects of
sustainability and how to implement them in
planning. Malm has been acknowledged
internationally for its sustainable urban
development in Vstra hamnen and the Housing
exhibition Bo 01 of 2001 (State of the World
2007, Giddings et. al. 2005). Malm is also a good
city for a discussion on scale, since it is very much
part of an ongoing urban development and
transformations at the scale of the region,
involving scalar shifts from one hierarchical level
to another, as old villages and towns becomes
transit-nodes for commuters, local squares and
services decline and retail spaces increasingly
appear at inter-district or even interurban levels.
Bo 01 was a pilot-project, trying to build the
city of the future, by focusing on e.g. ecological
sustainability and promoting the compact city. Italso stressed the important role of architectural
and urban design in sustainable development. The
evaluations made (Larson et. al 2003) argues that,
although Bo01 could be regarded as successful in
terms of ecology and technology, the aspects of
social and economical sustainability tended to be
weaker. Sandstedt & st also trace of functional
planning ideology in the effort of planning for a
general user, where socio-economical
stratification and differentiation of the populationare not addressed (Sandstedt & st 2003:164; on
user, cf. Forty, 2000: 312 ff.).
In the complement toMalm comprehensive
plan (2005) one can now see a general and wider
approach to sustainability than the one
accomplished in Bo 01. The focus is now very
much on how to integrate the three aspects of
sustainability, social, economical and ecological.
This integration might cause contradictions as

6/10
6(10) Conference Architectural Inquiries, Gteborg 2008
different aspects of sustainability rely on different
criterias for success. However, the contradictions
of sustainability go deeper still, as the same efforts
might increase a certain aspect of sustainability at
one scale, while decreasing it at another
(Marcotullio & McGranahan 2007). So far such
aspects have been discussed at national, global
and regional level, but not so much at the level of
the urban.
a. Stabilising scale at the level of an area (intra-
territorial bias)
There seem to be a clear tendency in most plans
and planning documents of setting a territory, and
thus a scale at which sustainability is discussed, be
it the city region (Frey 1999), Bo 01 (Dahlman
2003), the municipality (Malm P), or the inner
city area (Malm 2005), and then keeping to that
scale. Bo 01 was, at first, planned to be socially
more heterogeneous, but at one point the city
chosed to look upon the question of integration at
the scale of the municipality claiming that Malm
needed more wealthy tax-payers. They thus
argued for social homogeneity at the scale of the
area to increase a greater heterogeneity in terms of
income at the scale of the municipality (Sandstedt& st 2003:165).
To some extent the planning of Bo01 has focused
on the area as an isolated object of itself. It was
planned as a spatial enclave and the aspects of
sustainability were primarily dealt with as an
intra-territorial issue. Evaluations and discussions
have tended to do the same, focusing on the scale
of the area, or a certain building, not just at an
actantial level, but at the level of a network (cf.
Larsson et al 2003, Dahlman 2003 & Laurell2002).
This intra-territorial fetishism (to put it blunt)
should not be confused with spatial fetishism,
which is much discussed in scale theory. In
Amsterdam Zuidas European Space,
Swyngedouw criticises the tendency of solving
certain social problems by way of territorial
planning, changing focus from comprehensive
planning to projects for urban development
(Swyngedouw 2005:70 f). This, might in turn lead
to a spatial fetishism, treating space in itself
rather than the social relationships that are present
in (and produce) that space (Lefebvre 1991,
Collinge 2005). This is to some extent a critique
of solving problems that are social by spatial
interventions, Following the trail of actor-
network-theory, one could guess that problems are
indeed always both social and material/spatial
(Latour 1003, 2005). Thus leaving the question of
spatial (or social) fetishism aside there is,
however, another related problem at stake here:
that of a fixed scale, delegating sustainability to be
solved within the boundaries of one (or at best a
number of) territories, an intra-territorial bias.
Even though the sustainability of the area at hand
is prioritized in planning, its effects are in fact
multi-scalar.
Indeed, the modernist tendency of
territorialisation, building the city as molecules,
objects, zones or big boxes, is a well known one.
Modernist architects often discussed their
architectural projects and buildings as enclosed,
self-contained systems (Forty 2000:94). Panaeri
et al (2004) points at Le Corbusiers Unite
dHabitation (Paneari et al 2004:116) as ahistorical key example of how the urban
morphology of block and street was transformed
to the single building, reducing city building to the
building of monuments. The issue of sustainability
seems to have triggered a new interest in the
neighbourhood as a unit for the city or urban
region, conceptualising them as TODs, TNDs,
urban villages, or communities of different sorts,
etc. (Frey 1999:41). However, the neighbourhood
as a base for intervention is sometimes too largefor some questions, such as safety, and too small
for others, such as integration and employment
(Lahti Edmark 2004:165ff). As for now, urbanist
issues are mainly described in terms of nodes and
connections reducing the discussion of mobilities
to relationships between nodes and subnodes or
centres and peripheries. Such models still have the
problem of non-differentiation; they set up a rather
homogenous morphology, echoing modernistic
7/29/2019 Setting the ScSetting the Scale of Sustainable Urban Formale of Sustainable Urban Form
7/10
Setting the Scale of Sustainable Urban Form 7(10)
examples such as the Linear city, Broadacre city,
Ville Radieuse, etc. (cf. Dupuy 2005). Such
uniform, standardized ways of living seem even
more utopia now than ever. To host all the
activities of contemporary society, one would
expect differentiation at least at the level of the
region. Regional structure can not be built from
bottom up alone, neither from a few uniform
elements such as centres and sub centres.
Malm planning seems to be more careful in its
attendance to important routes (capital routes)
than planning in general, and also than most
research on sustainability. An explicit focus on
strkplanering, planning around important routes
has been advocated for example in projects in
stergatan, Norra Sorgenfri and Bennets vg
(Malm 2006, cf. Persson 2003). These projects
play important roles on different scales as they
both enhance the local city spaces and connect
different parts of Malm with each other.
Morphological literature often tends to point at
the road structure and the urban grid as important
and generative aspects of urban form (Caniggia &
Maffei 2001, Hillier 1996, Hillier & Hanson
1984). If one adds mixed mobilities to the often
repeated demand for mixed uses (in debates onsustainable urban form), the question of
intermingling scales would be addressed in a more
explicit way.
b. Stabilising the scale to that of the city centre
district (the geometrical bias)
The model of the compact city often explicitly
or implicitly refers to the old European city
cores (cf. Guy & Martin 2000). In the planning
material of Malm we can see a lot of examplesof this, from the planning of Bo 01, explicitly set
up with old Venice as a model, to the large
emphasis put on Malm innerstad in the
Comprehensive Plan and other planning
documents, such as Mten i Staden. At some
points this is not just an intra-territorial bias (as
suggested above) but also the fetishisation of a
special area, grain and thus a scale: Malms
styrka och utvecklingsmjligheter ligger i stor
utstrckning i innerstaden (Malm 2005:28).
According to Malm planning documents, the
Malm work of sustainability focuses on the
integration of all three aspects of sustainability. It
is also stated that Malms most important
contribution to an ecologically sustainable city is
to maintain a compact city; the inner, denser city,
good for cycles and pedestrians. Economical
sustainability is focused on enhancing and
expanding the inner city, it is the stadsmssiga
(urban) businesses that should grow. When it
comes to social sustainability, the main buzz word
isMtesplatser. In the textMten i Staden (part of
the sustainability work through the project Vlfrd
fr alla), good examples of meeting places are
named, and about 80 % of these are located
wholly, or partly, in the inner city.
Discourse on sustainability started a process of
de- and reinsitutionalization (Lundquist 2004,
Hajer & Zonneveld 2001), where a lot of the old
planning issues needed to be reappropriated
within the new discourse. After one hundred
years of deurbanization it does not come as a
surprise that the pro-urban rhetoric of post-
modern urbanism has survived, and beenadopted by the sustainable form discourse.
The fetishisation of the inner city, setting its
spatial scale and extensions as a model, is also
problematic in the perspective of recent changes
of urban development. In a sense it seems as if
the inner city is gradually becoming a district of
consumption (Krrholm 2008) and mono-
functionality. Its role as a live model for mixed
uses is hence running the risk of becoming out-
dated.
c. Stabilising the process of scaling (the
hierarchic bias)
The discourse on sustainability actually still
echoes the Ebenezer Howard triad-perspective, be
it town, town-country and country, or urban-
suburban-rural. There are centrists, decentrists and
compromisers (Frey 1999:27), monocentrists and
7/29/2019 Setting the ScSetting the Scale of Sustainable Urban Formale of Sustainable Urban Form
8/10
8(10) Conference Architectural Inquiries, Gteborg 2008
polycentrists (Okabe 2005). However, a lot of
urbanists of today seem confident in that a simple
hierarchy no longer works as a metaphor for the
city. The urban region consists of a whole range of
overlapping hierarchies and even non-hierarchical
structures. In discourse as well as in planning, one
can sometimes find a tendency of establishing one
hierarchy for the city, setting the process on how
to scale up and down (bias towards a specific scale
hierarchy).In Malm for example there is the inner
city, the districts, and the municipality. Most
hierarchical planning seems to create a focus and
competition between municipalities, since these
make up the strongest nodes of the hierarchical
structure. The scale of the region is still quite
weak in Swedish planning, but at least discussed
and analysed by Lnsstyrelsen and Region Skne.
Latour has always focused on processes rather
than places (2005), arguing that space and times
are constructed in networks of heterogeneous
actants. He has also criticizes the notion of scales,
(other criticism of scale see Brenner 2001,
Collinge 2005):The whole metaphor of scales going from the
individual, to the nation state, through family,
extended kin, groups, institutions, etc. is replaced
by a metaphor of connections. A network is never
bigger than another one, it is simply longer or
more intensely connected. (Latour, 1997:3, cf.Tryselius 2007:68)
The quote could, in a sense, be read as a pleading
for a non-fixed concept of scales, where scales are
produced rather than pre-given. Scale is the level
of complexity set by the size of the network and a
different scale imply a network of a different size.
It is sometimes assumed that cities change in
parts rather that in their entity (e.g. Frey 1999:45).One has to come up with district and build the city
from bottom and up. Caniggia & Maffei suggest
that different scales have different time intervals
of change. Caniggia & Maffei have, however also
pointed to the of scalar change
It might be argued that the old city centre in
some aspects might be loosing its place as a
privileged node in the urban region: the
Mumfordian shift(as we might call it in this
paper) when the old urban and rural centres are
deterritorialized and dispersed. Centres are,
however, also reterritorialized and we might
perhaps also talk of a Caniggian shift(if such an
expression is allowed) where centres de- and
reterritorialize not just geographically but also
hierarchically. Svgetorp-Hyllie is a retail centre
that will not just have impact on the neighbouring
local retail centres. It already has a considerable
impact on all the local retail centres in Malm
where new retail areas now are produced and
enacted at a new and different spatial scales (e.g.
Svgertorp, the pedestrian malls of the inner city,
Pilelyckan, Center Syd, etc.). This also includes a
shift of territorial scales. As the pedestrian
precinct has been territorialized as an urban type
on a scale between the urban core and the street, a
lot of issues, activities and forms, formerly
handled or enacted on certain scales, now seem to
take place at a scale produced by the pedestrian
precinct. New retail is thus established at new
spatial scales affecting the whole field of retail
establishments, destabilising previous structures
and starting the process of finding a new balance
and hierarchic structure at other scale levels(Caniggia & Maffei, Alppi 2006).
5. Concluding remarks
If the discourse on sustainable urban forms could
inform us on how to build better urban
environments, I think it is as a tool for integrating
issues and problems that formerly were
specialised or sub-optimized, counteracting a
splintering urbanism (Graham & Marvin). One
main issue here is a multi-scalar approach. Suchan approach need to address the current tendencies
of scale stabilisation discussed above, including
the problems of scales being territorially,
geometrically and hierarchically fixed and pre-
given.
