Arena Zagrebis the multipurpose
indoor arena located in the south-western part of Zagreb, Croatia, that has primarily
been planned as a central sports hall for hosting the 2009
World Men's Handball Championship.
However, since venues of such capacity cannot be
profitable if capable of hosting only sporting competitions, Arena has been
designed as multifunctional hall with all spatial and functional characteristics
that enable maximal flexibility and provide numerous events. This influence is
mostly present in the flexibility of the grandstand, in preserving sufficient
and various spaces reserved for athletes, other performers and event managers,
in providing simple and fluid visitors circulation from entering point to the
seat on the stand and offer various catering facilities, in dividing the whole
building in smaller mutually independent spatial zones that can be used separately,
in acoustic interventions inside the hall shell and at last in securing
sufficient bearing capacity of steel roof structure capable for suspension of
additional scene equipment.
When experienced in city macro-scale, Arena Zagreb is
positioned at one of the city main high-way entrances, as an extension of Savska
Street - one of the main city traffic line axes as well as an extension of Jarun
Lake - one of the main city recreation zones. Experienced in city micro-scale it
is positioned in the district with huge development plans, representing the
central point of the new planned shopping / entertainment centre surrounded
with new planned residential zones. By recent reconstruction of access roads
the whole area got suitable and well dimensioned traffic connection to the
remaining parts of the city.
This multi-functional venue is
composed of 6 floor levels, covering total GBA of 90.340 m2 on
a 29.540 m2 footprint.
Functional area partition follows the circulation routes of different users. Underground
level is mainly garage space approachable by 2 car ramps with total 956 parking
capacity (additionally, the 3.300 parking places in future nearby shopping centre will be used as
well). On the ground floor the field of play with all necessary athletes-,
performers-, judges-, trainer?s facilities are positioned as well as rentable
office area. The central arena?s
court can be transformed depending on the event.. The 1st floor
represents the main pedestrian approach level with four main entrances to the
venue. The visitors enter the grandstand directly from this level or by rising
to the 3rd floor passing through the circular halls with numerous
catering facilities, which are partly connected to the pedestrian platform and
usable also independently from the venue. The 2nd
floor is reserved for VIP-guests and media stuff having their own fully
equipped spaces with possibility of multi-functional usage also for
conferences, workshops or congresses. The restaurant on this level offers
direct view to the court and can be used during events, but also independently.
The 4th floor is reserved for technical equipment, and is also
connected to catwalks distributed underneath the roof and used for maintenance
of lighting and loudspeaker devices assembled along them. All described zones
are mutually independent and equipped with sufficient number of separated
accesses with very clear user?s circulation system-quick and easy entering and
exiting is secured, and mixing user?s circulation routes is avoided.
Arena Zagreb is also designed for hosting numerous other
sporting, cultural, entertainment and business events such as indoor football, basketball, volleyball, indoor athletics,
hockey, other sporting competitions and also concerts, exhibitions, fairs,
congresses and family shows. In order to adequately accommodate such events,
numerous supporting facilities are provided - catering, sanitary, cloak room,
office and similar spaces; also the small training hall with its own facilities
and smaller multi-functional spaces on the 2nd floor can be used for
mini congresses, workshops and / or lectures.
The flexibility of this venue is most evident by the grandstand
transformability. According to the main seating configuration for handball
competitions (also basketball, volleyball, tennis and indoor football) the grandstand
covers 15.024 seats of which 151 incorporated for disabled spectators. The
lowest part of the grandstand is a zone of 15-row retractable stands (26-row at
the northern side - potential stage position) with 4.556 seats (plus additional
132 free seats at the court level). The remaining part of the grandstand is
fixed and incorporates 10.336 seats divided on lower and upper stand. This
includes 314 VIP seats in front of VIP boxes. For other sports events (table
tennis, badminton, gymnastic, boxing, wrestling...) there is a possibility of
putting additional seats at the court level, and for indoor athletics, all
telescopic stands must be retracted, which reduces the capacity. Cultural and
entertainment events (concerts, exhibitions, fairs?) demand the grandstand to
be transformed in line with the requirements of the event organizer, so the
ground space can be used for additional seating or standing places. If the
nature of the event requires reduced seating capacity, the upper part of the
stand can be enclosed using the suspended textile partitions.
The unique shape of this
building is strongly inspired by its significance in the city context, but also
by its mega-structural characteristics that predefined main bearing elements.
Shaped as a protective rib cage around the building essence ? the court, 86
large pre-stressed, pre-fabricated concrete curved columns form the main
fade, mutually connected by illuminate semi-translucent polycarbonate
envelope that enables various light effects.
The elevated pedestrian access
platform connects the building through several pedestrian ramps and staircases
to the existing surrounding as well as to the neighbouring new planned shopping / entertainment centre, representing by its emphasis the future gathering point.
The example of last Olympic Games in Beijing demonstrates
the spectacular and theatrical context of contemporary sporting events, which
requires adequate spatial response in architectural solutions for hosting
venues. On the other hand, their size in comparison with the standard city
scale, also implicates the significance they have in the global city image.
However, it takes much more: by well designed shaping synergized with
structural requirements and urban context all conditions are fulfilled for iconic
recognition and for access to the list of city emblems. Hopefully Arena Zagreb
achieved that intention!
