Citizen-Led Urban Agriculture And The Politics Of Spatial Reappropriation In Montreal, Quebec, Claire Emmanuelle Bach

Dissertations and Theses

Urban Agriculture (UA) has been practiced in Montreal, Quebec for well over a century. In the last five years or so, a renewed enthusiasm for UA has manifested itself in the form of citizen-led UA projects. The latter are often established in residual spaces, from vacant lots to sidewalks, and alleyways. These more spontaneous and informal UA practices point to a shift in how urban inhabitants perceive and use urban space. Through a case study of informal UA projects in Montreal, QC, this work brings attention to the dynamics surrounding the establishment of citizen-led UA projects, paying special attention to …

Unitized Wall Systems, Ossie Pleasant, Lauren Sanchez, Nick Vipond, Sergio Palleroni, David Posada, Tucker Jones, Zgf Architects

Research-Based Design Initiative

ZGF is working on multiple large towers with short timelines that would benefit from quicker construction, which led us to unitized wall panels from a series of manufacturers. What often makes the construction process difficult is that there are independent organizations with differing priorities that must work together toward a common goal. By decreasing the number of trades, and minimizing construction time, a prefab system might allow earlier occupancy to regain building costs. With direction from discussions with the ZGF team, our efforts were initially focused on the comparison of three specific unitized wall systems: Island Exteriors, Sotawall and Enclos. …

The goal of this research is to develop a quantitative framework for the analysis of the development of urban form …

Cyclist Path Choices Through Shared Space Intersections In England, Allison Boyce Duncan

Dissertations and Theses

In the last several years, there has been growing worldwide interest in making streets safer for all users--pedestrians, cyclists, and motorists. One approach, shared space, is a traffic calming technique as well as urban design concept. This technique strives to fully integrate the roadway into the urban fabric by removing elements such as lane markings, curbs, and traffic signs. By removing these elements and creating a more plaza-like space, these sites become ambiguous and no user group as priority. The technique is relatively new, and the majority of existing research concerns pedestrians only. This mixed methods research focused on six …
