Embodiments relate to a plastic wall panel, comprising a hollow body having external walls and defining an internal cavity. The external walls include: a first major side wall, a second major side wall opposite the first major side wall, a minor top wall, a minor bottom wall, a first minor end wall and a second minor end wall opposite the first minor end wall. The minor top wall and the minor bottom wall each define mating structure to mate and align with another adjacent panel so that multiple panels can be tiled together to form at least part of a sound attenuation barrier. The hollow body defines a passage extending between the first and second major side walls and through the first and second minor end walls to receive a reinforcing beam.

A method of additive forming of a 3D object by layering solid base blocks (3) comprises the following steps: a. arranging at least one guiding element (2) oriented in the direction of forming of the 3D object; b. depositing a first layer comprising at least one solid base block (3) in the horizon of the first layer; c. depositing at least one further layer comprising at least one solid base block (3) at a horizon spatially spaced from the horizon of the first layer in the direction of forming the 3D object;
while at least one base block (3) of the at least one layer is arranged in the region of the at least one guiding element (2) and is arranged with at least one cooperating means (4), cooperating with the said at least one guiding element (2).

3D object can also contain various solid base blocks (3). It is advantageous if the first layer is arranged on the base plate (1). It is advantageous if at least one base block (3) is arranged with a fastening means (5), for example an adhesive. It is advantageous if, after step c), the base plate (1) and/or the at least one guiding elements (2) are removed. The 3D object can be strengthened by a thermal process.

A building block comprises a rigid housing defining a chamber and plant fibers contained within the chamber. A construction system comprises a plurality of such building blocks, selectively stackable to form a wall. A method of construction comprises obtaining a plurality of such building blocks, inserting plant fibers into the chamber, and stacking the plurality of building blocks to form one or more walls.

The invention is about a modular foldable brick that enables architectural elements such as stacked walls, arches, corners, doors, windows and wall niches to be constructed at indoor and outdoor conditions that divides, restricts and secures a certain space; Due to the possibility of folding the storing and carrying of this brick is possible at a minimum weight. The brick is connectable within itself and also attachable to others for constructing architectural elements as wall building systems. The foldable brick provides a foldable brick body that forms the outer walls and an inner wall being formed with three techniques; connecting/fixing (A-B groups)/encircling (C group). All three techniques are related to the forming of the detachable wall building system's entity unit foldable and sustainable brick. All these three techniques are used simultaneously.

A modular wall unit for a modular wall system includes a first elongate reinforcement member comprising at least one tubular portion for connecting the wall unit to a further wall unit of the wall system. The wall unit also includes a body at least partially surrounding the reinforcement member along its elongate length. The reinforcement member provides strength to the wall unit and allows a connecting element to engage with the at least one tubular portion. The connecting element can connect the wall unit to a further wall unit. This allows formation of a wall system where multiple wall units are interconnected via the reinforcement members and connecting elements. A kit including a wall unit and one or more plugs for assembling a plurality of wall units, a method for forming a wall unit, and a hanging device for supporting a frame are also described.
