9 (Material)


Material selection here isn't about achieving an authentic Samoan aesthetic, it's about being honest regarding which materials keep a relationship alive (ʻafa, siapo, local timber, basalt) and which materials are functional concessions the argument openly admits to (ETFE, sealed archive linings), rather than disguising every material choice as equally rooted in place when it isn't.

Explanation

Façade — the ground-level woven zone

This is an important material decision, because it's the only surface a visitor touches. Would use ʻafa (sennit) cordage over a plaited pandanus or coconut-leaf screen rather than a generic "natural fibre" because ʻafa carries its own inherited protocol: traditionally, sennit-making is skilled, gendered, and often communal labour, tied to specific plants, seasons, and knowledge passed between people rather than bought off a shelf. It isn't just a texture choice, it's committing the building to depend on that knowledge continuing to exist and be taught. Ths is the story behind the material, the façade doesn't just look woven, it obligates the institution to sustain weaving as a living practice, or the screen eventually fails and can't be replaced in kind.

The ethical tension worth naming: pandanus and coconut fibre degrade in a few years under UV and salt air, which is exactly why you built the maintenance calendar into design

  • There's a real risk the fibre-replacement labour gets treated as a maintenance cost line rather than a cultural practice, which would quietly convert generative metaphor back into a lashed image kept alive by contractors rather than community.

Façade → the timber rib structure itself

For the exposed ribs glulam ribs would be best for this curved ribbed vault


Façade → the ETFE covering

This is the one non-vernacular, non-local material in the building → manufactured, imported, petrochemical in origin. The building resists carbon-dependent material logics everywhere it can, and concedes at the roof, to deliver reliable weatherproofing at this scale, which is the argument being tested honestly rather than performed.

Interior linings → by ring of exhbition galery moving back in time

  • Outer ring (wrap): timber board lining, warm and approachable → this is contemporary, everyday material, appropriate for the "recent context" content it displays.

  • Middle ring (binding): siapo (tapa) panels as a lining in controlled bays, siapo is made by beating and decorating barkcloth, a practice with its own gendered labour history and its own vulnerability (light-sensitive, fragile). Using it here means the lining itself models the same care and conservation ethic the archive teaches. The story worth telling is that the wall becomes a teaching object before any exhibit label does.

  • Held centre: exposed basalt only, nothing applied over it. Stone lining as the strongest material statement in the building using restraint as the argument.

  • Archive wing (enclosed end): could be more steel mesh lining on the wings, same honesty as the ETFE, protecting the very deep-time material the building exists to hold.

Flooring → main and rings

  • Plantation-grown coconut timber (niu) or locally milled hardwoods rather than ifilele, which is culturally significant but increasingly scarce (specifying a threatened species for a building whose entire argument is about not extracting from the land without relationship would undercut my own position). Coconut timber is a tree already deeply embedded in Samoan material culture (food, oil, fibre, construction) grown on the very land the centre sits on, so the landing is made from the plantation's own regenerative resource rather than imported hardwood.

  • exposed metal flooring (perforated or grated steel) Punched with repeating circular or diamond-shaped holes. This has an open, mesh-like, grid texture that allows light and liquids to pass through you experience some of the basalt plinth below

  • for basalt area, finely grained, matte surface that looks and feels like compressed sand or soft stone suchas sandstone or snadblasted stone, with powder like fine gravel, crushed stone, and exposed natural excavation soil/earth

  • center is pure basalt stones as display (not walking on but to observe)
