The redesign of the Zeilgalerie shopping centre, which opened in 1992 and is renowned far beyond Frankfurt’s city limits, includes a completely new look for the façade and a full makeover of the public areas inside the complex. Due to the paramount significance of the front of the building in terms of typology and how it fits into the urban setting, 3deluxe’s design concept focuses closely on the architectural surface and its deepening in content, structure and materials. As it is the only exterior view of the complex that is enclosed on three sides, the façade facing out onto the Zeil shopping mall is therefore representative of the entire architecture – the perception of shape gets reduced to the perception of space. The building’s use as a self-enclosed and experience-oriented consumer world means that the façade can be completely disconnected from the building’s interior, thus permitting the creation of an independent design concept for this section.
In its function as brand architecture, the Zeilgalerie’s appearance must be able to reflect lifestyle and design trends alike. Here, architecture, which in principle tends to focus on constancy, approximates the dynamic processes of change in fashion and product design. Lighting effects based on complex computer programming help change Zeilgalerie’s look and with the ambiguity involved allows for personal interpretation and identification. Several façade levels of varying designs create intriguing layered effects as well as a visual impression of depth.
The new façade design gives Zeilgalerie a modern and unique appearance that stands out decisively from the architecture of the surrounding department stores. The façade’s unusual black and white colours, its filigree ornamentation and the integrative interaction of architecture, graphic design and light orchestration will create a distinctive character for the building on Zeil.
As a reference point to the existing architecture – designed by Darmstadt-based architects Kramm & Strigl as a stylistic mix of constructive modernity and post-modernity – the building’s characteristic tripartite structure has been preserved. However, an overarching colour scheme and connective architectural elements now combine the three single structures into one visual unit. The façade now features a more uniform look compared to the many parts from which it was formerly composed, thus communicates spaciousness and prestige, corresponding to the building’s use as an exclusive shopping centre.
The existing glass façade of the semi-cylindrical structure on the left is clad with horizontally arranged strips of curved matt-black aluminium panels. Viewed as a whole, they form an aesthetically appealing pattern of lines that, thanks to its irregular layout and the different strip widths, conceals the distances between floor levels. This creates a striking appearance, which is furthermore intensified by the use of dynamic lighting. Moreover, filigree metal ornaments and Alucobond panels screen printed with white dots enhance the design’s complexity.
The glass front of the central structure, which houses the shopping centre’s vertical development, is coated with a transparent printed film. The subtly visible motif is a graphic artwork depicting the location’s urban feel. It turns the glass surface into an imaginary space that evokes inspirational discoveries. The daylight penetrating the film projects the latter’s colours onto the interior, thereby painting interesting light patterns in the lounge areas adjacent to the façade.
The existing façade of the structure on the right, which is composed of multiply folded perforated sheet metal that originally concealed a kinetic light sculpture, will be replaced with smooth cladding made of matt-black aluminium panels and varnished glass. Here, the Alucobond sheets, which equally feature in the left structure of the complex, are not printed but laser-perforated in the same pattern as well as backlit. The renovation concept takes up the original idea of an interactive computer-controlled façade by providing a technologically and artistically innovative media installation at this point.
Light orchestration of the façade
Made up of several levels, the media installation envelops the right structure’s entire façade with a softly pulsating system of ornamental light. A rectangular surface made of doubleglazed glass and measuring approx 260 sq. m. is mounted flush with the Alucobond panels. Behind it, there is a rhombus-shaped grid composed of 310 LED strips. Each of the overall 13,700 light diodes can be controlled separately, thus allowing for a large variety of aesthetic light images: Clear-cut, geometrical patterns flow into the seemingly organic interplay of light and shadow; delicate linear accents alternate with striking, large-scale effects. The LED grid is omitted in the black finish of the rear glass pane, allowing light in the form of sharp-edged lines to emerge. These light diagonals are in turn superimposed by an orthogonal graphic that is printed onto the transparent film between the glass panes. Moreover, from time to time on the surrounding façade areas the dot screen flashes up, providing a visual continuation of the convex structure on the left. On the right-hand side of the building, this pattern has been laser-cut into the cladding sheets, enabling the light from the approx. 2,500 LED modules installed behind it to shine through. The varying interplay of the different design levels makes for a fascinating complexity and atmospheric intensity.
Correspondingly, the cylindrical tower is also illuminated with light: Horizontal lines of light flow softly along the façade strip’s lower edges. In darkness, the building’s tripartite structure is more pronounced – its ensemble character is deliberately emphasized by the illumination. The Zeilgalerie’s light orchestration is to be understood as an artistic and abstract realisation of illuminated advertising, which has long been an inherent part of the architecture of commercial buildings. However, rather than concrete advertising slogans it conveys the urban vibrancy of the location and translates it into atmospheric light images.
