Here’s something you don’t expect to sit on: surgical masks. Nearly 10,000 of them, to be exact. But that’s exactly what Design PY created in Hong Kong’s Tai Kok Tsui neighborhood with Tidal Stories, a spiraling urban installation that quite literally traces where the ocean used to be.
The concept is brilliant in its simplicity. Tai Kok Tsui was once a coastal area, but over a century of land reclamation pushed the shoreline further and further away. Today, most people walking through this district have no idea they’re treading on what was once underwater. Design PY decided to make that invisible history visible again through a helical seating structure that maps the old coastline right onto the public space.

What makes this project especially clever is how it tackles two challenges at once. First, there’s the environmental angle. The pandemic left us with a staggering amount of medical waste, and those 9,200 upcycled surgical masks in the installation are just a tiny fraction of what ended up in landfills and oceans. By incorporating them into public furniture, Design PY transforms waste into something functional and meaningful. Second, there’s the cultural preservation piece. Urban development often erases neighborhood memory, but Tidal Stories brings it back in a form people can literally interact with every day.
The installation isn’t just about looking pretty or making a statement (though it does both). It’s actually being used. Elderly residents rest on the benches. Nearby workers grab lunch there. People passing through stop to sit and chat. The design reactivated what was basically a forgotten corner of the neighborhood and turned it into a gathering spot.
But here’s where it gets even more interesting. The metal tabletops aren’t just tables. They’re engraved with references to Tai Kok Tsui’s industrial and coastal past, functioning as both amenities and educational tools. The whole installation doubles as an informal museum, hosting architectural tours and community events that help people understand how their neighborhood evolved from fishing village to dense urban district.
This kind of design thinking feels especially relevant right now. We’re all grappling with questions about sustainability, about how to deal with waste we’ve created, about preserving cultural identity in rapidly changing cities. Tidal Stories doesn’t just answer these questions theoretically. It shows what’s possible when you combine circular design principles with community engagement and historical awareness.
The helical form itself is striking. It curves and spirals through the space, creating natural gathering points and visual interest without overwhelming the neighborhood’s existing character. You can see the installation from different angles as you approach, and each perspective tells a slightly different story about the relationship between past and present.
What’s refreshing about this project is that it doesn’t lecture. It invites. There’s no heavy-handed messaging about environmentalism or preservation. Instead, it creates an experience that lets people discover the layers of meaning on their own terms. Maybe you just want a place to sit. Maybe you’re curious about the unusual materials. Maybe you start reading the engravings and realize your neighborhood used to look completely different. All of these are valid ways to engage with the work.
The use of surgical masks as a primary material might seem gimmicky at first, but it makes perfect sense when you think about it. The pandemic was a collective experience that generated collective waste. Using that waste to create something that serves the collective good completes a kind of circle. Plus, it’s a reminder that design solutions don’t always require pristine new materials. Sometimes the most sustainable choice is working with what we already have too much of.
Tidal Stories proves that urban furniture can be so much more than benches and tables. It can be a history lesson, an environmental statement, a community hub, and a work of art all at once. That’s the kind of multifunctional thinking we need more of as cities continue to evolve.
