“Green gabion walls” are simple structures made of gabions (wire baskets) made of galvanized metal mesh and filled not with crushed rock or stone but with soil substrate in which plants grow.
Gabion walls can be free-standing structures but can also be installed along vertical surfaces. They require a foundation on poured concrete plinths and foundations.
Gabion greening :
1) Line the gabion, made of galvanized mesh, with geotextile to protect the soil substrate from spilling out.
2) Fill the gabion with soil substrate.
3) Between the meshes of the mesh, make small cuts in the geotextile, into these cuts plant seedlings of greening “vertical garden” plants.
Application:
Against the walls of buildings, after protecting them from moisture. As free-standing elements – screens, fences.
Disadvantages:
The construction is cheap to implement but takes up a lot of space and is very heavy.

London Paradise Park Children’s Center
The project was a collaboration between the architecture studio DSDHA and landscape architect Marie Clark. Ground cover plants, climbing plants and shrubs were used to green the wall. The wall is greened by 70,000 plants – irrigation is provided by rainwater collected in containers on the roof of the building.
Due to poor maintenance, the vertical garden pictured here no longer exists.
- Zodiak Pavilion in Warsaw.
Individual walls are located in front of the Zodiac Pavilion – Warsaw Pavilion of Architecture in the center of Warsaw.
Destiny:
(a) for local communities
Easy-to-execute object. For construction, I use ready-made gabions or all their systems. You can green individual gabions or create whole walls from them – then they require foundations – such solutions are best commissioned by a specialized company involved in the installation of systems, eg, gabion fences.
Made of rust-resistant and weatherproof galvanized steel, the wall is very stable and durable.
(b) professionals
The system requires foundations.

Variations on:
An interesting example is the construction made of metal tubes (and irrigation system) forming something like a tower, in 2010 this object was located in Versailles on the territory of the royal gardens of Versailles. The construction was most likely made in this way:
– the tower structures integrated into metal tubes have been twisted to support plastic (perforated) flexible tubes which are at the same time a green structure irrigation system,
– plastic tubes are wrapped in tape, which contained the seeds of annual flowers. The plants grew according to the principles of hydroponic cultivation without the participation of land (all nutrients were supplied together with water),
– excess water was collected in the pool where the tower stood, so that it could be reused for watering plants.
