Duinwaker
Where I learned that a strong concept is not a design.
The question
Design a visitor centre rooted in a single species of the dunes. I chose the duinpieper, a bird threatened by the Dutch nitrogen crisis: acid rain stripping minerals from the soil, nitrogen-loving grasses like bochtige smele smothering the heath and the open sand.
Research → concept
My thinking started from one question: how can a structure give something back to the landscape? An early idea was a limestone form that erodes and returns nutrients to the soil. That shifted into a second question, how can a visitor contribute, which led me to plaggen, the old heathland practice of stripping vegetation to keep the soil poor and open. From there came Duinwaker: a silent festival where visitors trample invasive species and drag dead branches through the sand, disturbing the soil exactly as the landscape needs.
The turning point
I spent so long generating concepts that I left no time to design. My final structure was weak, and I had to resit. In the resit I went back to my very first site sketch (a pile of large branches) and the whole design grew from it. The sketch I made before I knew anything held the answer.
What I learned
Research and concept mean nothing if I don't reserve time to let them become form. This exact weakness, doubting endlessly and never committing to a path, is what the Double Diamond method later gave me a tool to fix.
