Khedivial Cairo: An Evolved Metabolism …

Khedivial Cairo: An Evolved Metabolism
Now located within a city of 17 million people, the urban structure of Khedivial Cairo was planned when the city’s population consisted of only 350,000 people. The metabolism of Cairo has evolved, along with its structures of social and economic exchange, transportation, urban ecology, and its imagability—or comprehensibility. The 19th century structure of urban spaces requires adaptive reuse to address over development brought on by contemporary densities and movement systems.
Our proposal suggests an ecological urbanism that reconciles the grand civic expressions of the 19th century urban system with the new energies of the functionalist city. This Gordian knot of elevated highways, congested surface roads, extensive automobile parking and sprawling informal markets are integrated into a new open space system that optimizes the city’s intensified energies. The DNA of 19th century urbanism is recombined with a 21st century verticalized urban order that manages an unprecedented magnitude of resource flows in four novel spaces: 1) an extended Opera Mall, 2) an Ataba Square Covered Market Plaza and Flyover Gateway, 3) the Hamdi Seif Al Nasr Multiway Boulevard, and 4) the new Great Lawn of Azbakiyya Garden. These four spaces deliver new ecological services combined with the expansion of urban services towards a new sustainable Cairo.

The metabolism of Cairo has evolved, along with its structures of social and economic exchange, transportation, urban ecology, and its imagability—or comprehensibility. The 19th century structure of urban spaces requires adaptive reuse to address over development brought on by contemporary densities and movement systems. Our proposal suggests an ecological urbanism that reconciles the grand civic expressions of the 19th century urban system with the new energies of the functionalist city. This Gordian Knot of elevated highways, congested surface roads, extensive automobile parking and sprawling informal markets are integrated into a new open space system that optimizes the city’s intensified energies. The DNA of 19th century urbanism is recombined with a 21st century verticalized urban order that manages an unprecedented magnitude of resource flows in four novel spaces: 1) an extended Opera Mall, 2) an Ataba Square Covered Market Plaza and Flyover Gateway, 3) the Hamdi Seif Al Nasr Multiway Boulevard, and 4) the new Great Lawn of Azbakiyya Garden. These four spaces deliver new ecological services combined with the expansion of urban services towards a new sustainable Cairo. Opera Greensward Opera Square is extended into a public greensward with new outdoor performance space, a gateway landmark, and an intermodal transit hub with underground parking. The proposed gateway structure, harboring a dot screen pattern of the former Opera Hall, reclaims the lost civic quality of the square’s eastern edge. Housing a visitor overlook at its top, the gateway provides a new backdrop and staging for performance venues on the greensward and underground access to the metro and automobile parking underneath. Opera Greensward reestablishes a civic anchor recalibrated to the new social energies of a larger Cairo. Ataba Square Covered Market Plaza and Flyover Gateway Recognizing the necessity for flyover expressways to relieve surface traffic, a new “mat building” reorganizes the surface of Ataba Square as a covered pedestrian zone to accommodate spillover market activity. The Flyover Gateway atop the mat structure civilizes rogue highway engineering structures through the mat urban prototype that can be repeated throughout Cairo. This vertical urbanism shapes and shelters a climate-friendly pedestrian landscape underneath while proposing an automobile- scaled landscape above with green roofs and ventilation towers that function as urban lanterns. The mat prototype is an exemplary urban solution since it multiplies the urban surface (and shade), laminating functions of conflicting scales and speeds in the same space. The pedestrianization and enhanced livability of Ataba Square is accompanied by land use changes that favor a mix of residential, office, and live-work functions. Hamdi Seif Al Nasr Multiway Boulevard A new multiway boulevard integrates dedicated flow paths for various transportation modes involving bus, rail, auto, and pedestrian lanes. A cross grain of pedestrian N 1 1 2 3 4 5 5 5 5 6 7 8 9 10 11 12 13 14 15 16 16 16 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 bridges and tunnels establish new connections between Opera Greensward and Azbakiyya Garden. The vegetated multiway boulevard mitigates heat island effects while facilitating improved intermodal transportation services due to the relocation of the bus station and new tram service on the boulevard. This well-regarded street type introduces a resourceful and efficient traffic planning tool complementary to the urban planning vocabulary that defines Khedivial Cairo. Great Lawn of Azbakiyya Garden A new Great Lawn, terminating the axis of 26th of July Street, provides an urban refuge while organizing peripheral cultural programs at a more intimate scale. The northwest quadrant of the four-square lawn is punctuated by a large hill that overlooks Opera and Ataba Squares while making this green landscape visible to those outside of the gardens. The garden periphery is composed of fusion landscapes that celebrate both Arab and Western place- making traditions. Indeed, proposed water features, typical in the most celebrated Arab gardens, will function in tandem with a convective cooling infrastructure located beneath Azbakiyya Garden. The periphery gardens reestablish a well-defined and orderly transition between bustling streets and quiet gardens. The periphery absorbs the casual siting of the metro facilities and relocation of the book market to a shaded plaza at the western edge. Opposite this, a catenary theater structure terminating the axis of 26th of July Street extends the National Theater complex to create both garden and street frontages. The greensward, lawn, multiway boulevard, covered market, and flyover gateway reconstitute a symbolic urban structure to this section of Cairo while solving for the new metabolism of a 21st century Cairo.
