The extensive system allows for a reduced structural load while providing a stable vegetated surface adapted to challenging urban conditions. Sedum was the natural choice: resilient to drought, wind, and high temperatures, yet capable of producing spectacular blooms during favorable periods.

The extensive green roof discreetly complements this renovation. A system using drought-tolerant plants adapted to the local conditions was chosen precisely to avoid burdening the building with unnecessary maintenance requirements. In a renovation of this kind, there is no room for mistakes: every layer matters, and every detail must function reliably in the long term without compromising the historic structure.

First, we define the vegetation areas, and then the layers are installed according to a recipe that leaves no room for improvisation: protection and filter layers, a drainage layer, and only then the lightweight substrate specifically designed for sedum.

The result is a project that demonstrates how nature can enhance the character of a historic building, transforming rigid architectural elements into a living and welcoming environment.

The extensive green roof installed at the Balvanyos resort was designed from the very beginning as an integral part of the landscape rather than an element added later. The building is surrounded by forest, and the goal was for the green roofs to blend seamlessly into the surrounding greenery rather than stand out. For this reason, a simple and durable extensive system established with sedum cuttings was selected.

We succeeded in transforming the roof of the new kindergarten in Avrig into a living space that blends naturally into the green landscape surrounding the town’s medieval center. The project was designed to respect the spirit of the place while offering children a tangible example of sustainability right above their classrooms.

The green roofs of the new sociocultural center on Șincai Street in Alba Iulia are beginning to take shape, transforming a simple concrete surface into a living space that is much more environmentally friendly.

The implementation of a green roof system on the terrace of a mall located in the ultracentral area of Brașov represented one of the most complex logistical challenges in our recent portfolio.

The vegetated layer is designed as a small ecosystem, not as a perfectly ordered surface. Sedum spreads naturally, with variations in color and texture, while shrubs break the monotony, add volume, and create the feeling of looking at a real garden rather than a roof simply “covered” in green.

The evapotranspiration of 100 m³ of water over a few summer weeks on an extensive green roof provides active cooling that far exceeds the cost of the water and is dozens of times more efficient than the thousands of kW of electrical energy consumed by air-conditioning systems.

From a technical standpoint, the two systems work hand in hand: the roof reduces building overheating, while the green façade functions as a thermal and acoustic filter. In practice, the difference is clearly felt during summer. Not by chance, Penny’s sustainability report shows significant energy savings.

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

This green terrace is not a simple “modern add-on,” but a natural extension of ecological construction and responsible restoration. It supports proper drainage, reduces temperature fluctuations, limits the formation of condensation, and brings nature back to a place from which years of misguided interventions had pushed it away.

The design does not try to be more than it is, but it does its job: it softens the building, adds a layer of greenery to a built-up area, and transforms a technical terrace into an element that truly matters visually.

In a resort like Băile Tușnad, where nature is the main asset, such a roof is not only a practical solution but also a matter of common sense. It reduces the environmental impact of construction, integrates discreetly into the landscape, and demonstrates that it is possible to build in a modern way without breaking the connection with the surrounding nature.

The extensive green roof system with a sedum blanket, installed three years ago, has stabilized excellently and shows vigorous vegetation.

The extensive green roof on this U2 tower block in Timișoara is one of those projects we have literally watched grow before our eyes.

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.

There was no luxury of heavy machinery or large-capacity cranes here. Everything was done by manual lifting, with materials brought up piece by piece, in a confined space with difficult access and careful attention paid to every single step.

For this residential complex, the project quite literally kept our heads in the clouds, as we worked on the 11th floor. The challenge was twofold: we had to install an extensive green roof at height, while also developing the green space below, located above the complex’s underground parking. The two phases were treated as separate projects.

The extensive green roofs on the buildings of the Vivido residential complex were not treated merely as technical surfaces to be solved, but as real components of the living experience.

Small green terrace with sedum vegetation, carried out under the principle: “No green roof will ever be rejected because it is too small.”

2 years, 70 trees, 2,000 shrubs, hundreds of perennial plants, thousands of square meters of lawn, automated irrigation system, green roofs

The clients, who spend a large part of their day in front of a computer, wanted a home that is not only functional but also breathes together with the surrounding nature. Not a cold, isolated villa, but a place that gives rest to the eyes and the mind when you step onto the terrace or look out the window.

At first glance, a multi-storey parking lot seems like the last place you would expect to see greenery. And yet, the project in the Hipodrom area demonstrates exactly the opposite: that urban infrastructure can be functional without being visually aggressive.

The complex was nominated for the National Architecture Biennale Awards, 2025 edition

Located right near the sea, on a building permanently exposed to wind, salt aerosols, and sudden temperature variations, this green roof enters spring in a spectacular way: blooming uniformly, without gaps or "tired" areas.

These are pre-cultivated vegetation mats, primarily composed of succulent species from the Sedum genus. These perennial plants are known for their resistance to harsh climatic conditions, including drought, intense UV radiation, and extreme temperature variations.

In an urban context increasingly suffocated by pollution and concrete, every square meter of greenery becomes a breath of fresh air for the residents of large cities. The innovative project of bus stops with vegetated roofs has proven to be one of the most efficient and sustainable solutions for integrating nature into urban space, successfully transforming simple shelters into true oases of greenery.

Green roofs reduce the heat island effect, improve stormwater management and help capture carbon dioxide. However, their expansion raises a fundamental question: how safe are these systems in the event of a fire and how do they compare to EU and Romanian fire protection regulations?

The future of urban planning is green and blue. Without the systematic integration of green, blue roofs (with meteoric water retention) in the urban infrastructure, Romania will miss a crucial chance to build more resilient, healthier and more livable cities.

The green roofs installed on all hospitals in Stuttgart total approximately 93,000 m², an area that functions simultaneously as insulation, stormwater management infrastructure, ecological support and urban resource for reducing extreme temperatures.

In order to increase the quality of urban life and align cities to European standards, it is essential to expand the green areas considerably in the coming period. Achieving this goal requires substantial investment and a well-thought-out urban strategy, but the positive impact on the health and well-being of communities will make these efforts fully justified.

Our company sets an ambitious goal: to transform the urban space into a greener and more dynamic environment, offering innovative solutions for green roofs, hanging gardens, plant walls and ecological facades. These initiatives contribute to improving the quality of life in cities and promote a sustainable model of urban development.

Due to their layered structure, green roofs act as a natural buffer, absorbing and retaining rainwater before it reaches the drain. Vegetation layers and integrated drainage systems slow down water runoff, thus reducing the risk of flooding.

The answer is categorically affirmative! With an experienced team and the right materials, such a roof can be installed even at low temperatures. In this article you will find out how the installation is carried out during the winter, what aspects to pay attention to and what benefits the projects carried out during this period offer.

On June 6, we celebrate World Green Roof Day, an ideal occasion to highlight the benefits that these sustainable solutions bring to our communities, including the positive impact on younger generations.

Scientific research has proven that the presence of nature in our everyday environment has measurable effects on physical and mental health. Studies show that simply looking at plants or a natural landscape can reduce heart rate, stabilize blood pressure and regulate stress hormone levels.

The owners' idea was clear from the beginning: the building should not stand out or seem forced into a mountain landscape that already has plenty of personality. The roof had to blend into the surrounding green, serving as a natural continuation of the slope and the forest behind it.
