From “boot” to “Medica”, around one fifth of the world’s leading trade fairs are held in Düsseldorf. Now, to ensure that it continues to welcome exhibitors, visitors and conference delegates in style, the Messe Düsseldorf is getting a new public face, turned towards the city, with an imposing entrance and a new exhibition hall and conference centre. Following the northern extension (comprising the new North Entrance, U-Bahn station and exhibition halls) created by sop | architekten in 2004, sop have been commissioned to redevelop Exhibition Hall 1 and the South Entrance.

The core element of the design is an over-dimensioned 7,800m² roof of translucent woven glass fibre. Visible from some distance away, it will reinforce the Trade Centre’s location facing the city between the Rhein and the Nordpark as well as bring together its various functions: new forecourt, generous foyer, new 12,000m² exhibition hall, conference rooms and existing congress centre. The transparent 16.5m-high foyer will be multi-functional, serving both as an entrance to the Messe and as an events venue. The site, which is to cover an underground car park, will open out onto the adjacent Nordpark, thus offering users an outdoor recreation area.

The New Trade Fair South welcomes its visitors in Dusseldorf underneath a spectacular canopy. The 20-metre high, tapered roof is part of the newly designed entrance zone to the south site of the trade fair according to a design by slapa oberholz pszczulny | sop architects. 170 metres in length and 93 metres wide, the polygonal roof made of translucent fibre glass fabric already offers plenty of space for visitors.

Architect Jurek Slapa created a cushion-shaped structure made of fibre glass fabric for this artificial sky which changes its face with the weather during the day and is illuminated in the dark by an exciting light scenography. The roof stands on 19 slender concrete pillars and consists of a geometrically rigid steel structure with 94 uniform diamonds. The actual roof cladding appears extremely light. The upper side is covered with a translucent fibre glass membrane which gives the impression of a cloud with its white, rhombic cells. The polyester fabric on the lower side is transparent, allowing a view through the slender construction up to the cloudlike roof. The shape of the surfaces of the two membranes is created by inner steel arches.

The formTL engineers were involved in the construction project at an early stage. In coordination with the architecture the feasibility of the diamonds was examined first. To examine the concept of the structure and the choice of material, pre-static analyses were carried out which made the necessary load data available to be applied to the steel structure. The choice of material for the two membrane fabrics, the functionality of the structure was also examined, for example with regard to drainage at the edges of the diamonds bays.

After the tender and the awarding to the membrane experts at Temme // Obermeier, formTL was commissioned again. The task this time was to prepare the final approval and workshop design of the membranes together with the attachment system. Part of the task was to develop a seam layout with little waste. For the visual approval, a 1:1 scale mock-up was created on which the execution of the fabric could be coordinated together with the architects. 

The two roof cladding fabrics differ not only with regard to their materiality and transparency. The different materials meet various requirements in terms of load bearing behavior and design: The upper cladding works as weather protection, while the lower mesh fabric is transparent, freeing up a view to the structure and the seam layout. For the cutting pattern generation, various compensation values arise depending on the materiality, so that cutting layouts for both sides of the membrane are applied. Because various angles of inclination also arose from the drainage concept for the diamond structure, 18 different geometries were finally developed for the roof membrane. 

With the reconstruction of hall 1 and the new South Entrance we have given our homebase a complete facelift towards the river Rhine. And have made it even better than before. With more presentation facilities, meeting places, and scope for your business. Because we are keen to give you maximum functionality or, in other words: to help you enjoy your time at the trade fair even more.

7,800 square metres on the River Rhine, with a good view of the Düsseldorf skyline – and all under a 20-metre translucent canopy: this is how we welcome you from now on. After 170 metres you’ll pass through the glass front of the new South Entrance. A few steps further up you’ll find yourself right in the midst of it: the Foyer with over 2,000 square metres of space – an area which is suitable for meeting up and for holding events. Also, it’s definitely worth lifting your eyes and discovering the glass-enclosed meeting room which protrudes into the Foyer above the heads of all trade fair visitors and convention delegates.

Are you still marvelling at the wonderful new views from the Forecourt and the Foyer? Well, be prepared for more. We’re now entering the new Hall 1, right next to the entrance area, along its entire width.
