My main thought behind the overall design of the wall was to match the rectangular pattern of the elevation of the mall, while incorporating the advertisements which do not dwarf the ones on the main facade.
Hence the small size of the bill-boards. Also, the bill-boards can be changed as per the requirement with additions/ subtractions of the number of shops and/or products. The pattern on the wall allows this flexibility in sizes also.
There are two frames of aluminum / mild-steel sections: One frame of flat sections is affixed to the wall. Another frame of box-sections is at a distance of 4'' from the wall. These two frames are connected to each other via 4'' box sections. This allows a gap for accommodating the lights/ back-lights, etc. Also, the box-sections can easily conceal the electrical wiring.
The main wall on which the frames are put is a stepped-one. This creates a playful perspective as opposed to the heavy monolithic mall on the side. The wall is kept blank with dark paint (The shade of darker Aluminum composite panel on the mall facade) to highlight the metal frames, bill-boards and planters in front of it.
The transformer box and the meter box are both semi-concealed with shutters of aluminum channels and perforated sheet metal to allow ventilation. The meter box is having glass panels in the shutter to facilitate reading without opening the lock. The transformer box is semi-concealed from the top also. The patterns of these both match the overall design of the wall.
