That’s actually a really clever idea—kelp farms as green walls could do double duty as a natural filter and a source of nutrition. I’d start by sizing the façade to match the plant’s growth rate, so the structure stays light and doesn’t need a massive support system. Then think about the nutrient delivery; a drip irrigation system that recycles greywater would keep the kelp fed while reducing the building’s water demand. The trick is to keep the plumbing discreet, maybe embed it behind the cladding, so the aesthetic stays clean and minimalist. I’d also run a quick load analysis on the frame, just in case the added mass of the kelp and water is a surprise. It could be a win for both the environment and the building’s resilience, but we’ll need to prototype and tweak the system before committing to a full-scale installation.

Absolutely, let’s start small. Pick a south‑facing wall so it gets the most sun, install a modular panel that can be swapped out, and run a few nutrient trials. We’ll monitor growth rates and light absorption, adjust the mix as we go, and keep everything as light as possible. That way we can iterate fast and see how it fits the building’s rhythm before going full‑scale.
