The design process can be thought of as the use of iterative and cyclical creative problem seeking/solving to identify and analyze ambiguous and complex problems and to conceptualize potential alternative solutions. Given the nature of creative thinking, solutions that demonstrate novel strategies or ideas are highly desirable. But where do such solutions-or ideas- originate?

Conceptual design is the portion of the design process where creative thinking skills- such as ideation- are utilized in the identification and exploration of a wide range of potential alternatives in response to a stated program and/or problem. Creative thinking skills such as ideation rely upon the reciprocal use of divergent and convergent creative thinking skills. Divergent skills are necessary to expand the breadth of potential alternatives beyond the immediate "solution"; convergent skills are necessary to evaluate the alternatives (and cycle into refinements, etc).   Divergent thinking allows the designer to critically examine a given context or problem and to explore a wide-range of creative alternatives that provide unconventional, novel and innovative solutions.  

Critical analysis and lateral thinking are essential to conceptualization as they allow for new perspectives on a problem. These new perspectives requires the designer to serve as a critic and to assume an external position relative to a given subject. This detachment allows for the critical distance so as to examine and question the problem from a variety of perspectives. The use of lateral thinking in the design process enables the identification of multi-various alternative solutions to a problem. Such lateral thinking design methods include first, the conceptual shift of perceived boundaries of a problem, which could also be thought of as changing the rules of the game to allow for a new view of the problem or potential solution; the second method includes the introduction of new information to the problem to expand the realm of potential solutions; the third method is the conceptual re-orientation of the values of a given problem; and fourth, the introduction of other individuals or insights to provide additional insight or perspectives beyond your own. Note that the methods are expansive in that they destabilize the problem framework itself so as to allow for alternative ways of conceptualizing and re-defining the problem. In this manner, the problem itself is problematized.

The Diagram as Method: Systems and Moments.

Within the scope of professional design services, the Conceptual Design phase is the transitional project phase following pre-design services. The work of Conceptual Design relies upon the initial research, analysis and definition of the physical and programmatic contexts to provide the basis of design. Based on the overall project approach and initial programmatic opportunities, conceptual design utilizes creative problem-solving to transform the problems and opportunities identified in pre-design into a set of speculative conceptual alternatives- or solutions- that unveil new site conditions and potential project trajectories. 

Given the divergent thinking of conceptualization, the work of conceptual design is intentionally expansive and the desired outcomes are not "one" solution per se, but rather a set of potential alternatives.  These conceptual alternatives are just that- conceptual in they are typically somewhat general and “blurry” relative to the eventual proposed design solution. 

Given the intent to speculate and conceptualize alternatives, iterative techniques of diagrammatic investigation and representation are essential.  Within design, the diagram is a projective technique utilized to explore, construct and demonstrate the reasoning- the idea- behind a design proposal.  As a method, the diagram allows for the loose and rapid generation of gestural experiments that investigate, project and record landscape complexity inherent to socio-cultural landscape processes and change.   As a milieu, the diagram records an idea and provides the cognitive territory to deconstruct, reassemble and represent speculative landscape systems, moments and programs. The diagram also aligns with figurative representations of the landscape as a set of operations and processes, which as a composite analytique enables the conceptualization of the landscape as assemblage.   The diagrammatic alternatives generated in conceptual design begin to illustrate how the project approach and program are translated into a range of potential outcomes and positions

The work of Phase 01 provided an initial understanding ; the work of Phase 02 provided a Project Approach and Programmatic Opportunities whereby the research and theory are combined into an overall project approach. The research and work of Phase 01 and Phase 02 now provide the basis of design for Phase 03.  

In this phase of work, you will build upon and refine your 3 (or more) potential opportunities for use as the basis of design. These opportunities become the primary point of orientation for design alternatives. Hydrosocial theory provides you the instrument of "detachment" and critical distance necessary for lateral thinking. In this manner, thydrosocial theory becomes a primary critical lens (but not the only lens) to re-imagine potential futures for the project approach and programs identified in Phase 02.

Utilizing techniques of divergent thinking, you will develop diagrammatic, conceptual design alternatives for each of the three project opportunities you have identified and refined.  You will utilize analog diagrams to project, maps and test potential landscape changes. These changes should be thought of and expressed as systems, moments and programs.  You may think of systems as landscape processes or networks- both designed and undesigned- that provide an underlying network within the landscape. For example, systems could be thought of in terms of the movement of water or people in the landscape or proposed or existing systems of infrastructure. Moments are those places and spaces that provide significant and direct visceral or temporal human experiences of the essence of the landscape (phenomenological interpretation of place). For example, one might think of the various proposed or existing experiences as providing particular moments on a site. These could be reinforced through material, spatial or other interpretations. Programs are the menu of proposed activities, uses and supporting elements and infrastructure.

Your work will be propositional and gestural with a necessary degree of abstraction relative to spatial form; in other words, the work will avoid specificity found in traditional methods of precise schematic design representation or site plan graphic symbology.

1) Part A: Analog Diagrams

For this phase of work, you will use three opportunities described in Phase 02 as the basis for conceptual exploration. For each opportunity, prepare 3 different design concepts. For each design concept, go through 5 different iterations, refining the prior concept based on your own critical analysis of the prior concept. After 5 iterations for each, you will have 3 preferred concepts for an opportunity. You will do this for each opportunity. The concepts should be diagrammatic in technique, loose- but legible. The diagrams should consist of systems, moments and programs for the proposed study site and surrounding context.

As a starting point, utilize Google Earth and capture an AXON image of the proposed study site(s). In general, the axon view should be taken at a 65 to 80 degree angle (or “tilt”) as indicated in the Google Earth view properties. You will want to include the subject area as well as a generous portion of the surrounding context. Utilize one of the opportunities as a starting point and develop three different conceptual designs that explore a landscape-specific expression of ONE opportunity. Analyze and critique the three concept and develop an additional three alternatives based on the self-critique of the previous concept. Continue this for a minimum of 5 cycles, for a total of 15 per opportunity. Do the same for two other opportunities, for a total of 45 drawings. Allow the work on one opportunity to inform the other two.  The studies should be completed in soft graphite pencil (2B to 6B) or Pentel Sign Pen atop trace paper (white or canary) laid over the aerial birds-eye or 3D model views. Try to use a landscape format of 8.5x11 and 11x17 or 1920x1080, landscape orientation. This size is intentional is it will not allow you to get too precise.  


Due: 45 analog diagrams, each on a seperate sheet, with your name and date prepared indicated in the lower right hand corner. In the upper left hand corner number the concepts in sequence that they were prepared.  Have these complete before start of class on Friday, October 19th.   On Friday, we will break into small groups of 3 and you will present your work to your peers. After this is complete, you will move into different groups and repeat in round-robin presentation format.

2) Part B: Analog Study Models

Based on the analog diagrams prepared in part A, you will prepare 3 conceptual alternatives. Each conceptual alternative should embody differing and favorable aspects of all three opportunities. The development of the three alternatives will be completed using 3D analog diagramming study models. The analog study models should utilize an aerial photograph - plan view, to scale and encompassing the entirety of your study area(s) and adjacent context. Recommended scales include 1”= 300’, 1” = 500’, or 1” = 1000’ depending on study area.

The aerial should be affixed atop cardboard, foam-core or other study base. Indicate proposed design changes using a mix of analog collage methods. iThe model materials should consist of the aerial photo itself in combination with mixed media of your choice, including chipboard, basswood, wire, mesh/screen products, poly-carbonates, canson paper, sponge, and other relevant materials of your choice. Given the scale of study, there will be a level of conceptual abstraction- this is intentional. No professional model materials such as model railroad trees, foam dust for grass, etc allowed.  NO digital models or laser cut models!

Due: Three, to scale analog study models representing 3 different conceptual design alternatives. Each model should be concpetual, yet professional in appearance. Due Friday, October 26th at start of class. You will present the study models to a guest jury (TBD).
