#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 fl oating over the pitch. A volcano and a

smoke ring if you may. The fi rst 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 artifi cial soil, act-

ing as a green roof, with only the entrances peaking out of it.

Above the top of the fi rst 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 fl oating over the hill, making it

iconic, memorable and unique. The smoke ring would be fi xed 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

fl exibility 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.

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.
