Iloilo Processional Theatre

Iloilo's cultural life happens in the open: music, dance, procession, theatre, ritual, food, hospitality. During festivals such as Dinagyang the streets themselves become the venue, with costume and rhythm and crowd turning the whole city into a stage. The brief was to give that culture a permanent civic home without taking it indoors.

The site sits in a tropical climate of heat, humidity, heavy rain, seasonal flooding and wind, on the edge between land and water. Those conditions are treated as design generators rather than constraints: roofs, thresholds, screens, courtyards and landscape are each asked to do environmental, social and symbolic work at once.

The project starts from a question. If precolonial spatial, ecological, structural and cultural knowledge had kept evolving under contemporary conditions, what kind of performing arts centre would it produce now?

Vernacular architecture is treated here not as a historic style but as an intelligence system produced by pressure: generations of adaptation to climate, material and culture, compressed into building knowledge. The design is held against four interacting forces, and the ideas that survive are the ones doing several jobs at once.

Environmental performance

Heat, humidity, rain, flooding, wind, ventilation, shading, ecological resilience.

Structural intelligence

Material logic, joinery, spans, modularity, seismic response, repairability, buildability.

Behavioural culture

Gathering, hospitality, performance ritual, thresholds, informality, communal use.

Symbolic culture

Memory, ancestry, ritual, land and water relationships, craft meaning, civic identity.

A panel of six AI agents was built to apply that pressure: Filipino materiality, form and design, culture steward, environment steward, structure, and Filipino vernacular intelligence. They were never asked to generate forms or images. Their job was critique.

At the centre sits the Vernacular Intelligence Evaluator. Every element gets the same question: what pressure produced this form? A roof must answer to rain, heat, structure, acoustics, gathering or symbolism. A screen must do environmental, social or material work. A symbolic gesture must connect to programme, orientation, ritual, ecology or construction. If an element cannot answer, it goes.

Each decision went to the panel alongside the team's own judgement. A move that satisfied the environmental steward but failed the culture steward went back to the drawing board. Across three rounds of testing the scheme read as structurally dominant: strongest in its visible timber tectonic, weakest wherever the behavioural and symbolic systems were still implied rather than proven. That is the point of the panel. It shows where a formal idea still needs grounding, and where the design is drifting toward the merely picturesque.

Once the agents and the architects were satisfied, the scheme moved out of rough massing and into a procedural pipeline. Using Claude Code and Codex, the design logic was translated into Python for Houdini so that the entire building could be generated procedurally.

That gave the project iterability at full resolution. Any parameter could be adjusted and the whole building regenerated, with roof geometries, shading densities, woven structures, airflow patterns, modular assemblies and acoustic surfaces all tested as variations rather than as single fixed models. Testing against the four pressures could continue at competition resolution instead of stopping at the sketch.

The building is organised as a civic sequence rather than a sealed theatre object, moving from two porous ends that face the city toward a central epicentre of performance. Arrival follows the same logic as performance itself: visitors move through exterior and sheltered outdoor space into a broad civic band before reaching the performance core.

Along the processional route runs a continuous exhibition of traditional garments and festival clothing, keeping the building tied to its cultural function even when no festival is running, so the route works as a living archive rather than a dormant corridor. Behind it sit three workshops: a scene workshop for traditional objects and theatrical elements, a costume craft workshop, and a building craft workshop dedicated to maintaining and repairing the bamboo and woven rattan facade. Craft, repair and cultural transmission become part of the building's everyday intelligence.

The zoning is tripartite: a public zone facing the community, an intermediate social zone acting as foyer and distributor, and the zone that holds performance and production. The middle zone is the hinge, a social room for the city on one side and a functional distributor for the theatre on the other. Not every square metre is treated as conditioned volume; the building encloses only what performance requires.

The first floor extends public movement as an elevated promenade. Bridges over the processional route keep people visually connected to performance from across the building, so gathering, watching and being watched become part of the architecture.

The auditorium is the climax, but the whole journey is treated as performative. City to threshold, threshold to commons, commons to concentrated spectatorship, and beyond that into the operational world that makes theatre possible. The plan is less an arrangement of rooms than an arrangement of states: of access, visibility, collectivity and enclosure.

Urbanistically the building meets its site as an interface. It extends outward through promenades, bridges and landscape, using floodable waterfront steps, terraced bioswales, rain gardens and a sunken mangrove flood defence to offer accessible edges and layered entry conditions that stay active well beyond ticketed hours. It does not simply receive audiences; it structures civic space around itself.
