Vertical Gardens: Nature Comes to the City
When thinking about architecture, images of stone, steel and glass usually come to mind. If we add the word ‘city’, a grey picture pops up in front of our eyes. However, the situation is slowly changing, and it is possible that future generations will perceive the cities as green and flourishing spaces. Green zones of cities are conquering the hearts of urban people around the world as vertical gardens are designed not only to infuse concrete jungles, but also to improve living conditions there.
The world of nature and plants have always been closely connected with the state of creativity. In the history of architecture, we see that connection as particularly close, though often indirect, when nature is the inspiration for it, and the shapes and elements it imitates and quotes have a stone, wooden, marble, clay, steel, or glass body. Rings, trunks, stems, green leaves: these parts are usually used to soften, round the strict geometric lines of the masonry and thus bring a person at least a little closer to his roots. In cities, which are essentially an expression of human separation, of distance from nature, such artificial elements of the living world are often the only means of reminding us of the inhuman source of creation.
Space Becomes More Valuable
Greenery began to penetrate everywhere. Trees and shrubs conquer places where life will seem impossible. Due to new technologies, roofs turn into meadows, terraces into gardens, courtyards into parks, and house walls become living paintings. Today, it is important to turn the urban world into a plant kingdom with the supremacy of nature. Green architecture professionals have noticed that any personal or commercial space that suddenly turns green or blooming, and is providing the environment a fresh, colorful, and vibrant feeling, becomes an extremely strong point of attraction. The whole surrounding space becomes more valuable where the green areas intertwine and become an integral architectural element. A vertical garden, also called a plant wall, is a harmonious ecosystem characterized by great biodiversity.
The plant wall begins its life as a two-dimensional space, like a painting that later, as the greenery grows, takes on volume, becoming three-dimensional. Such plant walls consist of three parts: a metal frame, a PVC layer and felt. The metal frame is hung on the wall or built independently. Thanks to this frame, the air acts as a very effective temperature and sound insulation system. Attached to it is a 1 cm thick PVC sheet, which gives the whole structure strength and is waterproof. Finally, a felt made of polyamide is laid, resistant to breakage and highly capillary, thus helping to distribute water evenly. It is in this layer that the roots grow. Tap water, saturated with various nutrients necessary for plants, is supplied to the wall from above. Watering and fertilizing are automated. Plants do not need soil if they have enough water and dissolved minerals, light, and carbon dioxide. A vertical garden usually weighs less than 30 kg per square meter and can be planted on any wall without any height and size limits.
