of six capital cities south of the border: Buenos Aires, Argentina; Havana; Lima, Peru; Mexico City; Rio de Janeiro; and Santiago, Chile.
Through maps, photographs, plans, and prints, the show examines how the colonial city, originally shaped by Spanish and Portuguese
regulations, developed during the republican era in response to industrialization, indigenous revivals, and other pressures. Objects on

The city’s façade consultant for the

based Façade Forensics, supported
the approach. In a letter to the city,
Lewis wrote that the building’s defects
“could not be corrected by restoration-
type repairs limited to traditional
preservation techniques.”
Recently, DLR Group did a mock-
up, affixing an aluminum panel to the
building’s exterior. To a surprising
degree, it resembled the original façade,
which might be problematic in its own
right. “I think where the discussion
starts with the Portland Building is
the idea of over-cladding and calling it
preservation,” says Theo Prudon, FAIA,
president of Docomomo US. “You
could call it interpretive restoration, I
suppose. But interpretations of history
are always problematic. When you
go into a historic building, there’s a
process of making clear what you did is
new. I think there is a concern that the
new interpretation will be seen as the
real thing. It’s an age-old discussion in
preservation. How far do you take it?”
Patrick Burke believes that the

needs of the workers in the building.

students to propose a small-scale

National Park Service site. Situated
at an abandoned coal mine in West
Virginia, the property is rich with
historic industrial structures, and
the students were encouraged to use
these as precedents to inspire their
own detail-focused designs.

Collaborators: The City of Toronto; Evergreen Brick Works; the Toronto and Region Conservation Authority
The Rivers
Andrew Hooke’s analysis at the level of the rivers examines how sediment and seed
dispersal can, over time, help to change and reinvigorate the landscape (above and
facing page). Built interventions such as benches, lookout points, and bridges help to
engage area residents with nature. His proposal includes dotting the river itself with
vertical rods containing seeds from a variety of native species that can be dispersed
by the flowing water, augmenting the natural landscape and repopulating local flora
over the seasons (previous spread).
161
The Ravines
Kangning Zhao’s investigation of the ravines in and around Toronto led to a proposal that
uses landscape as infrastructure to help redirect water flow and manage flooding. In order
to encourage area residents to engage with the natural landscape of the ravine, the project
incorporated pathways, benches, meadows, and bike trails. Sculptural interventions will
double as wayfinding devices to help people navigate their way around. A planting strategy
encourages the growth and spread of native flora.

The City
Projects focused on the city level
explored how to foster links between
the natural ravines and the urban
context of Toronto. Hannah Soules
looked into how stormwater runoff
can be reclaimed in a greenway in the
downtown core, bringing both native
plantings and public programming
to the neighborhood (right). Farmers
markets and cafés help activate
the streetscape and encourage the
connections to water. The canal in
Soules’ plan can shift uses depending
on the season—from a landscaped
waterway in the summer to an ice
skating rink in winter (opposite).
