Light green roof at Kaufland Odăi Bucharest

At Kaufland Odăi in Bucharest, this lightweight extensive green roof tells a special story. It was installed in the middle of winter, with frozen hands, snow-covered structures, and unforgiving temperatures. The kind of project that honestly makes you question twice whether it is worth continuing. And yet, it is precisely here that the true value of a technically and ecologically well-designed solution becomes evident, along with the strength, resilience, and determination of the ODU Green Roof team.

Spring arrived as the final test. The layers settled exactly as intended, the drainage and substrate performed flawlessly, and the vegetation not only survived but came back with strength. The roof, which had appeared inert and lifeless during winter, transformed into a coherent, continuous green surface, free of gaps or compromised areas. This says a great deal about the stability of the system and confirms that this is not a “showcase solution,” but one built to endure.

The photos capture the transformations a green roof goes through over the course of a year. During summer drought periods, Sedum colonies retreat, contract, and conserve their energy. This is not a failure, but a natural survival mechanism. Then spring arrives, and almost overnight, green reclaims the entire surface. In May–June, the roof bursts into a sea of yellow flowers, a clear sign that the system is working properly and that the plants are exactly where they should be.

Beyond aesthetics lies the less visible, yet essential part: protection of the waterproofing, thermal comfort, and that rare feeling of having built something that works with nature rather than against it.
