4 The glass walls on both sides are designed as a
post and beam construction with mutually offset
beams, with a ventilation joint fitted above and
below, and are suitable for retrofitting with textile
sun protection.
5 The functional rooms beneath the grandstand are
clad with an aluminium edge-case system facade
that has a high-quality anthracite-coloured coating.
6 The glass wall below the lower tier separates the
arena from the spectator walkway on the ground
level, and during competitions protects riders and
horses from noise from the reporting and tournament
management offices. In order to provide visual
protection, this all-glass structure is film-printed
with equestrian sported motifs.
reinforced concrete beams that transfer
their loads via cross-walls and round pillars,
made of reinforced concrete, to the foundations.
Glass on both sides provide protection
against wind and the elements. The
functional areas such as the sanitary facilities,
storage and service areas, reporting
office, tournament management office and
a meeting room are located on the ground
level below.
The three-dimensional design is highly innovative.
The grandstand thus does not end
to the rear with a line that is parallel to the
front but instead at an angle. As a result, the
seating rows rise up to their highest point in
the south-east corner. The southern side similarly
does not conclude orthogonally, but
instead opens up to form a representative
staircase. This effect is enhanced by an
up-to-18-m projecting roof structure that
seems to float above. The grandstand‘s
asymmetrical rise means that it too is inclined
and has its highest point directly above
the staircase. This open and inviting effect
is enhanced by the purely white appearance.
The surfaces of the seating areas,
the stairway and the sweeping roof are all in
a uniform shade of white, so as to give the
grandstand structure a clear definition. An
encircling aluminium sheet and the whitepainted
reinforced concrete parapet bring
together the roof line, the grandstand and
the rear outer wall.
The underside of the roof also contributes to
this effect, and is the primary focal point for
visitors. It is created by a paneled ceiling
made of 184-mm-wide aluminium panels
with a recessed covered joint. For increased
safety, the paneled ceiling has been screwed
to the supporting rail. This creates a
longitudinal structure that strengthens the
roof and at the same time bestows it with a
visual lightness.
