"Regardless of the differences among their citizens, cities always define their community as against the outside world; a settlement with internal defense walls cannot be called a true community." Community Design and Culture of Cities, by Eduardo Lozano pg 5 Throughout the history of human civilization, no manmade structure has been used to defend territory more than the Wall. Walls have been used to delineate the edges of empires, separate communities, limit migration and provide protection from enemies. As a result, the Wall has become synonymous with imperialism, segregation, racism and isolationism. But what about instances when security outweighs all other concerns? Is there a way to use the wall to maintain defensible space without negatively impacting the greater community? In the case of a military installation located in an urban environment, this is a real issue. Walls which protect the sensitive content within, also serve to divide the community. These necessary physical barriers have the incidental consequence of segregating the servicemembers and government civilians within from the community which they serve. I contend that the thoughtful treatment of these barriers can create a "third place" ripe for interaction between the installation and the surrounding community. By designing retail, educational and cultural spaces along the border, the security of the installation can remain intact while also fostering an active relationship with its surroundings. After all, as Eduardo Lozano states, "a settlement with internal defense walls cannot be called a true community." / Master of Science / “Regardless of the differences among their citizens, cities always define their community as against the outside world; a settlement with internal defense walls cannot be called a true community.” Community Design & Culture of Cities, by Eduardo Lozano pg 5 Throughout the history of human civilization, no manmade structure has been used to defend territory more than the Wall.

Winston Churchill said "We shape our buildings; thereafter they shape us." And this holds true for our cities as well. The intent of this thesis is to develop an understanding of the origins of the city, historic theories of planning, Utopian proposals, the current state of the city, and what the future the city may hold. The City of Aetheria is a world created via poetic imagination, the sublime product of mental activity; as a study intent is to discover the fundamental principles of the city, making explicit the nature and significance of fundamental concepts of urban design theories and utopian ideals while demonstrating the elements of urban form and the effects of urban process through history. Incorporating historical archetypes and typologies of architectural form; the design of the City of Aetheria was an investigational tool to study the Image, Form and Elements of the city. / Master of Architecture

Urban designers do not typically include research or evidence in practice, though the need for an evidence-based approach is becoming increasingly apparent. The way our built environment is constructed affects our health, well-being, and sense of place, as prior research has uncovered. Historically, urban design practice has negatively affected the well-being of urban residents by reinforcing inequitable social and power structures through the design of public space. Some theorists and designers have proposed evidence-based approaches as a response to these concerns. However, the emerging approaches can be disjointed. Tensions arise when deciding between the many types of evidence urban designers can use, and the different ethics they represent. In this thesis, I analyze three existing approaches to evidence-based urban design, including their benefits and their concerns, and ultimately argue that a convergent method is necessary. The conceptual framework I develop is one that responds to concerns of equity and accountability in the built environment, while also maintaining the significance of good design and acknowledging the inevitable integration of technology into society today. / Master of Urban and Regional Planning / Urban design is typically an artistic profession, and conducting or referencing research is not necessarily part of an urban designer's day-to-day. However, the need for a research-backed, or evidence-based, approach to public space design is becoming increasingly apparent. Prior researchers have suggested that the way our cities, neighborhoods, parks, roadways and other public spaces are constructed has an effect on our mental and physical health. Historically, these spaces have been designed to reinforce patterns of social inequity, which has negatively affected the well-being of urban residents. Some theorists and designers have proposed evidence-based approaches as a response to these concerns. However, the emerging approaches towards evidence-based urban design sometimes have conflicting physical and social goals. In this thesis, I analyze three existing approaches to evidence-based urban design, including their benefits and their concerns. I ultimately argue that a new method, which converges the existing methods, is necessary. The conceptual framework I develop is one that responds to concerns of equity and accountability in urban space, maintains the significance of artistry and good design, and acknowledges the inevitable integration of technology into society today.

The map is vitally important for space design. Maps allow designers to record and filter impossibly complex information about an environment. Designers try to capture a variety of aspects of a site through the use of graphic tools like maps and drawings. While there is a long-established conventional graphic language for recording characteristics of a site, this language is often inadequate when one attempts to explore and capture subtler perceptual qualities of urban environments. Many of these perceptual qualities can greatly inform a design and some designers have invented creative mapping strategies to record and analyze difficult aspects of a site. This position paper follows the work of innovative designers who creatively map perceptual qualities of urban landscapes. The theories and practices of these designers have informed my development of new creative tools for mapping my perception of space. The design portion of this thesis takes place in the Mexican War Streets Neighborhood of Pittsburgh, Pennsylvania and results in a plaza for the local Mattress Factory Art Museum. The design phase uses and evaluates traditional perception and representational tools of urban design. New creative maps are used to express what the traditional tools cannot. These creative maps are used to derive the concept for the site design as well as the design of the major site elements and materials. / Master of Landscape Architecture
