Lightweight extensive green roof – Penny Valu lui Traian

The lightweight extensive green roof without an irrigation system is the kind of solution that surprises precisely through its simplicity. It does not promise constant spectacle, nor does it try to appear more than it is. It works by its own rules, adapted to rain, wind, and sun—just as natural vegetation would if left to manage on its own.

The plants, mainly sedum and other resilient species, follow their natural cycle. In spring they emerge cautiously, in summer they burst into color, and in autumn they settle down, shifting their tones. The fact that there are photos from different flowering stages actually tells the story of this roof: it is not static, not mere “decoration,” but a living system that moves in rhythm with the seasons.

The absence of irrigation is not a drawback, but a conscious choice. The vegetation is specifically selected to withstand dry periods with minimal resource consumption. In the end, the result is a roof that asks for little but gives a lot: protection, insulation, and a piece of authentic nature high above the city.
