Models of openwork walls by Walter Leitner, a sculptor in Vienna. Such walls are suitable for various applications, including excavating individual exterior wall surfaces, dividing rooms, creating visual separations, and for outdoor use. Exterior applications are made of concrete blocks, while interior applications use gypsum plaster. The blocks are approximately 30 x 30 cm. These types of walls are non-load-bearing. For exterior applications, they can be installed, for example, under eaves or projections.
