Urban Systems

Definition

Urban systems is the metropolitan hybrid's second intent (Luna 2018): programming conceptualized as network rather than as core or container. The concept's founding move is a prepositional substitution: "Polycentrality would also require conceptualization of metropolitan hybrids as urban systems. This would change the notion of a 'city within a city' to a 'system within a city.'" Where the city-within-a-city (the atrium hotel, the microcosm of metropolitan architecture) internalizes the whole city inside one autonomous shell, the system-within-a-city distributes one programmatic system across many existing buildings — legibility, not autonomy, being the goal.

The concept's case is the Boston 2024 Olympic bid (2014): the city "would need visitor centers, of which there is currently only one, and it would need to build an additional 15,000 hotel rooms in order to bring the count to the necessary 45,000 required by the Olympic committee" — about seventy-five new 200-room hotels. Luna's counter-program: "Instead of building seventy-five new chain hotels, it could address the need for visitor and information centers and the need for hotel rooms by hybridizing both. This would create a network of recognizable information centers, visitor centers, and accommodations that not only benefit tourists but residents as well, rebranding the city by providing a perceptible typology of organization and city navigation." The system is thus a city-branding device built from adaptive reuse: "Through adaptive reuse, a city could brand itself by creating these systems, as seen in Venice for the Venice Biennale, where the whole city functions as a museum by distributing exhibitions in various palaces throughout the city. This encourages visitors to navigate the whole city, as opposed to just visiting key sites, and transforms potentially mundane buildings into part of a bigger agenda."

The concept's infrastructure branch holds that "the majority of disruptions in the urban fabric occur from infrastructure" — obsolete systems "leav[e] empty voids in the urban fabric" — while transportation infrastructure "presents the biggest potential for adaptability and reuse because of their existing structures": Tokyo's highways merged with retail and residential, the High Line's elevated track-to-park conversion, NL Architects' overpass adapted into "a market, flower shop, skatepark, kayak canal, and parking." Urban systems is therefore the continuity programme: maintaining "a continuous urbanity" by converting the fabric's disruptions (train lines bisecting the city, elevated highways leaving underutilized space) into its connective tissue.

Key Thinkers

• Rafael Luna — the concept's theorist: the system-within-a-city reformulation; the Boston counter-program; the Venice Biennale model; the infrastructure-reuse register (High Line, NL Architects, Tokyo).
• NL Architects — the overpass practitioner (no page — see log): the Dutch overpass adapted "into a series of urban programs that activated the space with a market, flower shop, skatepark, kayak canal, and parking."
• Deyan Sudjic — the image/navigation frame (via Luna): systems as "a perceptible typology of organization and city navigation."
• James Corner / Field Operations — the High Line as the concept's best-known built instance (via Luna; see Qureshi 2018 for Corner's reuse theory).

Related Concepts

• Metropolitan Hybrids — the intent's parent concept: "conceptualizing programming as urban systems."
• Interior Urbanism — the concept it reforms: the "city within a city" (Portman's microcosm) becomes "a system within a city" — the urban program distributed across existing fabric instead of internalized in one hermetic shell.
• Polycentrality — the sibling intent: cores (attractors) and systems (networks) as the two programmable formations of the metropolis.
• Programming — the operation: hybridizing two facility-types (information + accommodation; museum + palace) into one recognizable network.
• Adaptive Reuse — the system's construction method: the Venice palaces, the High Line, the overpass — "a city could brand itself by creating these systems."
• Terrain Vague — the system's repair domain: infrastructure voids, "empty voids in the urban fabric" left by obsolete systems.
• Obsolescence — the system's generator: "old infrastructural systems become obsolete" as new technologies arrive — disruption as the raw material of the next system.
• Housing — the network's dwellable node: the visitor-center-hotel hybrid's accommodation half; the micro-housing of the catalyst programme.

Source Support

Sources in the wiki that discuss this concept:

• Metropolitan hybrids: Programming for a thriving urbanity (Luna 2018) — the founding source: the Boston 2024 counter-program, the Venice Biennale city-as-museum, the infrastructure-reuse cases (Tokyo, High Line, NL Architects), and the system-within-a-city thesis.
• Spatial therapies (Qureshi 2018) — the High Line and post-industrial reuse context: Corner's elevated-rail conversion as urban archaeology and reuse's "urban archaeology" register (complementary source).

Open Questions

• Boston lost its 2024 bid — and the counter-program's network was never tested. Do urban systems depend on the mega-event that motivates them (the way the Venice Biennale depends on the Biennale), or can a bid-time system persist as ordinary navigation infrastructure?
• The Venice model "transforms potentially mundane buildings into part of a bigger agenda" — is that empowerment or instrumentalization? The mundane building becomes legible only as system-node; does the concept have a theory of what the building is when the event leaves?
• "A system within a city" is offered as the correction to "a city within a city" — but the atrium hotel's privatized microcosm and the Olympic visitor-network are both branding devices. Is the urban system the interior-urbanism critique's resolution, or its dispersal (the privatized microcosm multiplied into a privatized network)?
• Luna's infrastructure cases adapt transport structures (rail viaducts, overpasses). What would a system look like for the obsolete systems that aren't spatially linear — power plants, data centers, parking structures — and does "system" here name the reused thing or the newly created network?
