Disclosed is an economical and effective way of producing a double sided decorative wall using facing panels having a decorative face surface, in particular dry cast concrete panels having a regular surface structure, more preferably an embossed surface, most preferably a patterned surface. Further disclosed are wall components and a wall kit for a double sided decorative wall. The facing panels in the wall are stacked in a back-to-back arrangement into a pair of first and second back-to-back walls, which walls are interconnected by connectors which link at least one facing panel in the first wall to at least one facing panel in the second wall for forming the double sided decorative wall. The connecting members can be in individual connectors, or a combination of connectors for linking multiple facing panels or linking facing panels at corners or curves in the wall. The connectors can be of different length to enable the construction of decorative walls of different thickness. A modular wall system for double sided decorative walls forming both straight and curved walls is also disclosed. The system uses facing panels and connectors, wherein all facing panels are of equal thickness, but may have different lengths and may have different widths. The facing panels of the modular wall system all have graduated lengths, each length being a multiple of a base length L. Thus, the facing panels have lengths of 2L, 3L, 4L, 5L etc. To facilitate the formation of walls with corners, such as right angled corners, the facing panels preferably have a depth which is equal to L or a multiple of L. Building the decorative wall of two partial walls of facing panels with intermediate connectors renders the wall more economical than the previously known walls with base blocks and facing panels suspended from the base blocks on one or both sides.
