To discover and reveal the deeper substrate of the landscape is something the natural sciences alone cannot accomplish.” – Günther Voght
The Department of Urbanism at the Faculty of Architecture and Built Environment, TU Delft considers urbanism as a planning and design oriented activity towards urban and rural landscapes. It aims to enhance, restore or create landscapes from a perspective of sustainable development, so as to guide, harmonise and shape changes which are brought about by social, economic and environmental processes. In this respect we can consider urbanism as an object or goal-oriented interdisciplinary approach that breaks down complex problems into ‘compartments’ or ‘themes’. The core of urbanism is formed by the disciplines of urban planning, urban design, and landscape architecture. Giving shape to the relationship between man and natural landscape is a core task for this disciplines and involves civil-, agriculture-, nature-, and environmental based techniques as operative instruments. However, in order to work together effectively it is important to identify and develop the qualities of the involved disciplines individually. What is the particular nature of landscape architecture as an independent discipline? The presumption is that the answer can be found in a repertoire of principles of study and practice typical for landscape architecture. [1, 2]
Here the focus is on research
and design of the landscape ‘from the inside out’, as it could be experienced
by an observer moving through space. It elaborates on the visual manifestation
of open spaces, surfaces, screens and volumes and their relationships in terms
of structural organisation (e.g. balance, tension, rhythm, proportion, scale)
and ordering principles (e.g. axis, symmetry, hierarchy, datum and
transformation). The basic premise is that the shape of space, plasticity (form
of space-determining elements), and appearance (e.g. colour, texture and
lighting) of spatial elements in the landscape determine the relation between
design and perception. This principle addresses the form and functioning of
three-dimensional landscape space, which creates a spatial dynamic. This might
be the construction of a pictorial landscape composition, the framing of a
landscape or urban panorama, or creating optical illusions. The treatment of space is not only about designing merely, static
images but about the design of a kinaesthetic experience. The images are not
ends in themselves but part of a series of three-dimensional images that draw
together the architectonic or mental image of the composition. Since there is a
causal relationship between seeing and moving the role of movement is of great
The landscape is 'read' as a biography, as a palimpsest that evidences all of the activities that contributed to the shaping of that landscape. Here the concept of the longue durée is crucial, understanding the landscape as a long-term structure, which is changing rather slowly. The physical traces that time has overlaid can reinforce or contradict each other. Knowledge of these layers is one of the starting points for new transformations of the landscape involved, or for adding a new design layer. This principle involves the evolution of landscape over time and elaborates on operations of ‘erasing’ and ‘writing’ history. Operations of erasing history include: complete or partial eradication, etching, excision, entropy and excavation. Operations of writing history include: parcelling, infill, addition, absorption, enveloping, wrapping, overlay, parasitize and morphing. The genius loci, the character of the site, is at the heart of this principle. Examples include the re-development of industrial brownfields, and the conservation and transformation of cultural-historical valuable sites.

Landscape is considered to
be a relational structure connecting scales and spatial, ecological, functional
and social entities. Landscape is viewed as a scale-continuum. The design
involves establishing relationships via the attachment, connection, and embedment
of a specific site or location into the broader context at different scale
levels. A landscape intervention will have impacts on different levels of
scale, hitting interests of stakeholders operating on that level. Although
scale is a matter of grain and radius, it implies that a particular site is
always part of the larger context. Once the extent and grain of the site
(object of study) is determined, the rest is regarded as ‘context’. The reach
of scale is also important, because conclusions on a specific level of scale
could be opposite to conclusions drawn on another level of scale (this is
called: scale-paradox). This principle addresses working through the scales as
an important basic premise, for example for systematic elaboration of planning
strategies (e.g. regional planning and design) and design interventions (e.g.
project-based realization). This might include, for example, the development of
regional park systems as armatures for urban development, or the design of
water infrastructures with regional implications. Thus landscape design
operates on different scales of intervention, or conceptual zones, which
provide a cultural lens to landscape. In sixteenth-century Renaissance Italy
these conceptual zones were defined as: the ‘first nature’, the natural
landscape (wilderness, untouched by man), the ‘second nature’, the cultural
landscape (agriculture, urban development’s, etc.) and the ‘third nature’, the designed
landscape where the former two where absorbed, used and represented.

Here the landscape is regarded as a holistic and dynamic system of systems. The landscape is regarded as a layered entity where different processes and systems influence each other and have a different dynamic of change. In that respect landscape is an expression of the interaction between ecological, social and economic processes. The landscape is considered as a process rather than as a result. Natural and social processes constantly change the landscape, making the dynamics of the transformation a key issue in research and design. The design is like an open strategy, aimed at guiding developments, not a blueprint design. Projects play a role in open-ended strategies, as in staging or setting up future conditions (e.g. manipulating processes of erosion and sedimentation by water or the development of project-based master plans). Operations focus on the interaction between landscape processes and typo-morphological aspects and facilitate social and ecological relationships between natural and human systems. This principle of study and practice elaborates on models for understanding the landscape as system (e.g. layers-approach and systems thinking), and concepts like sustainable urban metabolism and urban ecology. It employs social and ecological processes to create landscapes that serve multiple objectives.
The knowledge reflected by these principles of study and practice forms the core of landscape design and expresses the integrative nature of landscape architecture. It embodies a way of thinking typical for landscape architecture and is visible in landscape architecture theories, planning and design processes and products.
