#1 Smoke Ring One of our favourite things about the programme given for the stadium was the requirement to integrate the stadium and the city. Initially, it sounds like a contradiction - a stadium is introverted by it’s nature. For the spectators the focal point is inside the stadium and since the building should house as many seats as possible a tall solid mass is created that does not communicate with the sur- rounding city. Our proposal suggests the creation of a split stadium. Partly cov- ered in ground and partly ﬂoating over the pitch. A volcano and a smoke ring if you may. The ﬁrst ring, as well as the pitch, the park- ing lot and several other functions would be slightly submerged and covered until a height of about 10 meters in artiﬁcial soil, act- ing as a green roof, with only the entrances peaking out of it. Above the top of the ﬁrst seat ring, a 10 meter gap would allow a continuous view of the city through the stadium, from the city into the stadium and from the stadium towards the city. The top seating ring would be concealed in a light-as-possible con- struction, that would appear to be ﬂoating over the hill, making it iconic, memorable and unique. The smoke ring would be ﬁxed on a set of columns that would include the horizontal moment axises – the stairs and the lifts. The top structure would also include the VIP rooms and some of the functions. the sustainable approach taken in this concept is of a more social nature. We look at the connection with the city and the the trans- parency as values of great importance in the relation to the con- text, and enables the community to feel greater connection to the place, that is open to all, not only for the paying crowd, the new sloped terrine created would encourage new uses instead of the conventional carpet of parking lots surrounding most stadiums. This green strip continues the master plan’s intention of creating an urban part, making the mountain a focal point in it.

#2 Chameleon This proposal does not regard the shape of the stadium itself, but an idea in which the facade and roof system take a new role upon themselves. Not only they would protect the spectators from the elements, they would also play an important role in communicat- ing the building’s status and use to the city’s inhabitants. The continuous facade and roof system could be positioned in one of four modes, acting as either an internal roof to cover stadium in case of rain, an external roof to shelter venues outside the stadium, a fully retracted mode, in which the roof covers the entire facade, and a half covered state in which the roof covers the top ring. This multifunctional roof system would act like an extrovert sign, allowing the people of the city to understand by a quick look what is happening at the moment in the building. The envelope itself would be modular and adjustable. The system must enable great ﬂexibility to adopt to changes in geometry. The moving skin would be a platform that could contain photo voltaic cells as well as built in RGB LED lights. By using small tiles and individually controlled LED light, the whole surface, on both of it’s sides could be used as a gigantic display and give unprecedent- ed visual e ects in matches, concerts, urban installations etc’. The internal part of it could emit a constant, balanced, and shadowless lighting when positioned as a roof, that would enable high quality TV broadcasting.
#3 lift! The city of Rotterdam is best known by it’s port. Since the site is located at the sea front, the distinct aesthetics of the cranes and harbor machines makes scene as a contextual choice. The cranes are massive and impressive mechanisms, that were designed to last and are able to carry tremendous loads. We came up with an idea to reuse unused cranes from the port (and other ports as well) to support the stadium and it’s roof, instead of investing huge amount of resources and energy to create new construction. Old cranes of various sizes and shapes could be used to support the seating rings, staircases and the roof. There is also the possibility to use them to lift the pitch upwards to the level of the upper ring in smaller matches when not all of the stadium is in use and even further to the top level in case the stadium is used as a concert hall or just to expose the grass to the sun in an optimal way.
