  • 15. Scenario 1. Recognition of the fact that seasonal floodings are unavoidable and hap- pening on a global scale across the whole coastline of Cuba, so the loca- tion at Havana has to be regarded as a local intervention. 2. Exacerbation of the paradoxal su- blime character of the sea, being both extremely beautiful and ex- tremely dangerous at the same time. 3. Recognition of the complixity and en- tanglement of all elements (water, wind, floods, rains) as a system ca- pable of producing emergent effects. 4. Site is considered as intermedi- air between city and sea, hand- ling flows of sea- and rainwa- ter as well as flows of people. 5. Utilizing flooding and salinity for creation of site specific experiences. 6. Creation of specific spaces that ena- ble one to reconsider and experience the relation between man and nature.
  • 16. LOCATION: global scale The chosen intervention site is located along the Malecon boulevard which runs continuously for 8 km connecting the Vedado, Centro Habana and Habana Vieja neighborhoods.
  • 17. Infrastructural network The Malecon boulevard is designed as a ringroad that is connected at certain points to a system of main secundairy roads. These connect to tertiary roads which open up the urban fabric of the city grid. Along the 8 km Malecon ringroad, there are only 4 points where both lanes of the boulevard can be accessed from the secundairy roads, one of them being the intervention site. It is clear that the traffic connectivity is a force that can not be neglected in the design. Legend Malecon open public space secundairy road intervention site tertiary road connection city-Malecon city grid both tra c directions connected to city
  • 18. LOCATION: glocal scale The site lies in front of the hospital and is currently occupied by Parque Maceo. The boulevard running along the Hospital towards the coast is one of the main shopping and public facilities bou- levards of the city, dividing the Vedado and Centro Habana neighbourhoods.
  • 19. Public artery Boulevard Padre Varela is designed as the public artery that serves both Vedado and Centro Habana with public functions. Wal- king up the hill from the sea, the street provides shops for daily neccesities, school, cultural institutions, an occasi- onal bar, some Peso-food vending windows and most prominent, the towering Hospital.

  • 24. LOCATION: local scale The site is bounded by two main car ar- teries and is provided with a important bus stop making it a very public space within the city.
  • 25. Inaccessible island In the current situation, the plaza between the Malecon and San Lazaro is fenced off and only accessible via an underground tunnel underneath the Malecon. In order to acces, first you have to cross the road which makes the fenced off area act like an unaccessible open space, a boundary between the city fabric and the sea.
  • 26. The site is bordered by two very busy roads which make it difficult to acces the space. Furthermore acces to the sea is blocked firstly by the Malecon road and secondly by the wall.
  • 27. Non-representative design “Today, the architectural project is not 2 designed, but negotiated.” Negotiating its way between forces and demands from the sea and the city, the desing will not draw its effect purely from its presence, but from its operative performance within its own context. In- stead of just a representative architec- ture, which is already completed by its own existence, this architecture is an active one, striving to produce effects out of itself. The aim of the design is to actualise virtual qualities inherent in the conditions that exist and the new blurred conditions that get created by the intervention, giving rise to a whole new realisation of becomings. In this active model of coexistence, the fragile boundary between city and sea is not seen as a static line but reconside- red as a constantly shifting zone of di- vergence. It becomes the place where two extremes meet: one the uninhabitable, the unphatomable, the other the epitome of habitation, the pinnacle of human planning and appropriation. Openness versus density. Natural versus manmade. 2 Gausa, Manuel - Guallart, Vicente - Müller, Willy This intermediate place gets affected by - Soriano, Federico - Porras, Fernando - Morales, José (2003) forces from both sides, negotiating the The Metapolis Dictionary of Advanced Architecture: City, demands of both entities into a single Technology and Society in the Information Age, Barcelona, yet heterogeneous multiplicity.

  • 28. Urban intervention related to sea conditions and human behaviour
  • 29. Wind behaviour Winds are an expression of the weather system that produces different conditions that manifest themselves through fluctu- ations in winds but also in varying sea conditions, from very calm to the seasonal Hurricanes and floods. Wind itself is invisible. Only its effects on dynamic mediation subjects like leaves of a tree or water that gets wrinkled can be seen. In other words, wind needs some- thing to act upon in order to make itself visible.
  • 30. Water behaviour Water is both a visible and a tactile me- dium that is essentially formless and pas- sive, only showing particular qualities when interacting with its surroundings. By designing a fixed mediating substrate, potential virtual qualities inherent in water as a medium will get actualised at different moments and places. They will project themselves upon the mediating ar- chitecture in a symbiotic way, generating a blurred field of interaction between the design and the elements that is in a con- stant state of becoming rather than being.

  • 32. Vertical zoning Analogy with ocean tidal pool
  • 33. 1. Spray or splash zone this is the most dry zone, receiving water spray or vapour from the breaking waves only at high tide. This zone oc- casionally gets flooded during storms in 2. High tide zone this zone gets flooded only a few hours a day, when the tides reaches its peak. 3. Mid tide zone mostly submerged, this zone is the bio- tope of small plants and animals that rely on a continuous flow and ebb of the water. This zone is continually in 4. low tide zone almost always submerged, this zone is the biotope of marine vegetation and bigger sealife that rely on water depth

  • 35. Water morphology Inclined tide-flat Calm conditions: will get more and more covered with water as the tide rises. Water flowing up and down this surface creates a thin film that changes the physical appearance of the surface underneath it and shows effects made by sun and wind. Stormy conditions: works as a wavebreaker when the tide lowers and the waveheight reaches 0,8 times the water depth (theoretical breaking point). Inclined wavebreaker Waves will roll up and over this oblique surface and start to break with a forward motion, causing the zone behind this type of wavebrea- ker to flood with water. Vertical wavebreaker The vertical wall will make the wave splash up upon impact, cre- ating a salt vapour splash zone behind it, shaped by windspeed and winddirection. Spray gets produced during high tide, water will only splash over during storms. Declined wavebreaker locks up the wave and redirects it back into sea. No water and no va- pour behind this edge condition.

At low tide, the whole site is accessi- ble, by moving through the folded lands- cape, perspectives and vistas constantly change. At high tide, only a small part of the site is accessible, the main circulation paths and nodes that give access to the programs. Visitors do not have the luxury of moving through the landscape, so they have less visual experience. The folds and main access nodes are dispo- sitioned in such a way that main viewli- nes to the open sea are maintained at all times. Views past the piers are important to understand the intervention as a smal- ler space in a bigger whole.
