The global project comprises the creation of a new botanical garden for the city of Barcelona, specializing in the flora characteristic of homogeneous climatic with the Mediterranean, such as California, Japan, Chile, South Africa and Australia.
The projected garden results from the layout of a triangulated grid which adapts the different formations of vegetation, placing them in "mosaics" (plan) and "transepts" (section), according to the different ecosystems and it tries to formalize the different buildings using the imagery of lightness and transparency. The geometric layout of the new gardens would base itself on botanical and ecosystem issues, as well as in the use of the concept of morphological convergence in vegetation, making it a tool of high scientific value and becoming part of the botanical gardens of next century.
The design is based on the idea of superimposing a triangular grid over the site. This grid would adapt itself to the terrain, unweaving itself at the edges and growing or diminishing in area in accordance with the slope. The orientation of the triangular grid would follow the three principal directions of the topographic lines, insuring that two ends of each triangle would always be at the same level, with zero slope. Other breakdowns of the grid would retain the same structural formation, responding to issues of accessibility, planting.
This irregular geometric order which varies according to the position on the site would allow the following:
- To rationalize the hidden services infrastructure, drainage, water supply...
- Provide the site with a hierarchical network of itinerary's responding to the use and slope, establishing primary and secondary routes related to the work in the garden.
- Confer an order which enables the scientific, pedagogic and ludic exploitation by permitting the ordering of the mosaics of different vegetation communities.
- Set conditions hidden within the project to organize future buildings: herbariums, greenhouses, umbracules, research and service buildings, following the same logic of intervention.
