Grandstand – Dressage Stadium,
Aachen
Site plan scale 1:4000
The site in Aachens Soers district has
specific facilities for all equestrian disciplines
and is internationally renowned.
Here, glamour in the form of celebrities
meets tough sporting competition. A
good example of this is dressage, where
the graceful elegance of each performance
hides the hard work and discipline
that goes into it. Dressage fascinates
spectators – so much so that
tickets for events even at the world’s
largest dressage stadium are generally
sold out a year in advance. For this reason
the Aachen-Laurensberger Rennverein
riding association, which runs the
site, decided to expand its facilities with
another grandstand capable of holding
1200 spectators.
An architectural competition was organised,
which was won by Aachen-based architects
kadawittfeldarchitektur with a design that
can be seen as an analogy to dressage. It
combines formal severity with visual lightness.
Towards the dressage area, the new
grandstand concludes vertically and rises to
the rear. It is designed as a stepped structure
made of reinforced concrete onto which
a projecting steel roof construction has
been positioned. The supporting structure of
the roof consists of a girder grid of welded
steel profiles with a trapezoidal steel sheet
that functions as a flat roof and stiffening
element. In the rear grandstand area, the
structure rests on a reinforced concrete
beam that encompasses the grandstand
slab. The roof loads are transferred to the
ground level and from there via reinforced
concrete circular columns to the foundations
using just four slender steel supports in the
front area. The grandstand is founded on
bored piles that are connected to each
other via centring beams. The underlying
grandstand structure is a solid construction
with a high percentage of prefabricated
components. The seating steps in the
grandstand‘s spectator area are made of
precast concrete. They are placed on
