DOUBLE SPIRAL WITH TRIANGULAR SUPPORT STRUCTURE

SPORTS HALL IN PRISHTINA, KOSOVO

The new sports hall will be situated next to an existing bus station and its elliptical traffic loop. The proposal by ENOTA & OUD+ Architects puts the building inside this elliptical traffic loop while maintaining the bus station at the focus.

The hall will be positioned on the northeast corner, which preserves the largest possible area for a public plaza serving as a multi-purpose outdoor space used by the neighbouring communities of Kalabria and Dardania. The entire public plaza is free from vehicular traffic. The organic design of various paved and green areas gives the space a recognisable character.

The building is lowered by one floor to hide the service areas underground and to avoid a disproportionately tall building with a doomed roof. The main concourse is easy to reach since it is only one level above ground. This puts the roof only two levels up and makes it accessible to pedestrians, transforming it into an open public space. The arrangement of traffic and communication flows around the building is the main driver for the formal concept. A circular spiral is cut into the surface of the plaza, much like one would cut a piece of paper, and then pulled upward to form a loop of pathways around the building. A split double helix facilitates a large flow of people around the building and upwards, providing external access to all parts of the sports hall. Smaller pockets of public space are created at various intersections of the spiral, allowing the placement of bars and restaurants that serve both the interior and exterior of the hall.

Up to 5,000 seats Inside the hall two seating arrangements will be possible: The smaller one with 3,500 seats will allow for a larger handball

court or three parallel basketball courts. With the help of extendable stands, this seating arrangement can be enlarged up to 5,000 spectators for high-level basketball competitions. This flexibility will facilitate multi-purpose use of the venue (fairs, concerts and smaller sports club activities).

The structure of the building is divided into two parts. The basement will be constructed with perimeter and load-bearing walls in reinforced concrete. Above ground, the façade ramps will be supported by a triangular grid of steel columns that follow the irregular ellipsoid geometry. At the roof level, the steel columns will support a compression ring that carries a tensioned cable roof above the main hall.

LIKE A SKATER’S FLOWING DYNAMIC MOVEMENT

SCA ICE HOCKEY ARENA IN ST PETERSBURG, RUSSIA

The design of the new SCA Ice Hockey Arena in St Petersburg follows the tradition of Constructivism. Architecture firm Coop Himmelb(l)au translates its expressive, open design language into a contemporary context: the filigree framework of its construction, based on Tatlin’s “Monument to the Third International,” is transferred to the flowing, dynamic movement of a person skating around the stadium.

The park is designed for year-round use. It is criss-crossed by two categories of path networks. The first category is straight axes that connect important points in the park and enable quick traversal of the facilities. The second category consists of paths that wind through the park. Various zones for sports and leisure activities are embedded in these path networks.

Without changing the existing planning inside the arena, a second, transparent cladding is created, which serves as a supporting structure for the overlying, dynamically cantilevered roof shaped like a flattened dome. It will be equipped with solar panels on the side facing the sun and with an LED screen above the main entrance.

Structural ring and roof structure A structural ring serves as additional support for the roof structure. The ring geometry is differentiated into four segments, which work within the global structural system, and four segments that support only themselves, as well as allowing large entrance openings. The wall-like steel structures support the roof in four different areas around the stadium building. They will be shaped as straight surfaces or reinforce the folded surface geometry with a second layer of structural elements. A spatial steel truss system based on a bi-axial layout composes the lightweight roof structure. The beam layout respects and adapts to the preexisting structural axis around the stadium bowl. It uses predefined support points. Truss directions are aligned with the main cantilevering directions, which creates a more efficient force flow towards the most strongly cantilevering parts of the roof.

The arena’s filigree construction is only interrupted by arches at those points where the stairs to the ring-shaped plinth are placed. This creates a covered arcade that is protected from wind and rain and that can also be used for merchandising shops and food stands. Balconies, which are attached to the thermal shell within these arcades, connect the functional areas inside the arena with the protected outside space and can also be used as lounges and restaurant terraces outside of event times. A transparent media screen made of LED dots inside the glass envelope will communicate the current events over a large area in the space around the arena.

MULTI-PURPOSE VELODROME IN COLOGNE, GERMANY

The Cologne City Council has taken the decision to have the velodrome converted into an allseason, heated arena for the purpose of establishing a federal and state centre for “cycle sport” by the Kölner Sportstätten (KSS) GmbH.

Owner and project developer KSS had already been granted federal and state funding for the project, after the concept developed by the world-renowned velodrome architects Schürmann (Münster), KSS and the Sports Council of the City of Cologne won the approval of the State of North Rhine-Westphalia (NRW) and prevailed against strong competition.

Excitement amongst German competitive cyclists is already great. The new NRW velodrome will be a sports arena that meets the highest of international standards and where the German national and Olympic teams will also train. Its multifunctional nature means it will satisfy the longstanding need for a sports arena that can hold 4,000 spectators for cycling events (and 3,000 for ball sports). This solution is much cheaper and quicker than constructing a multi-purpose sports arena of a similar size from scratch. The NRW velodrome is scheduled for completion by the end of 2024. The main focus when it comes to usage will be on cycling, which will take priority over ball sports.

Gerhard Reinke, Managing Director of KSS, welcomes the decision: “This is a significant step, not only for cycle sport in Cologne and North Rhine-Westphalia as a whole, but for Cologne as a centre for sport in general. The multi-purpose velodrome will be the new home for many sports, and the KSS team looks forward to a wide range of exciting sporting events.”
