The first elements, designed as "glass blocks" act as the building’s principal frontage: the window of the Botanical Gardens. Simple in volume, they dominate the entire scheme with a height of 8.40 meters. They shelter three different climates and describe (in terms of scale and volume) the different particularities of the various plant species. The timber skeletal structure offers a great flexibility to the volumes thereby capable of adapting to eventual changes in programmatic requirements.

The Northern facade of this “City of plants”, irregular and set back from the street, underlines the strong image of the greenhouses.

The other components, in contrast, more flexible and modular, stand as a loose assembly of "boxes” and “pebbles". They are set out in a more organic and natural way, connected to one another according to functional requirements.

The "boxes", of timber construction and natural wood panelling, constitute simple volumes, thereby facilitating the museographic design.

The “pebbles” formed in concrete with smooth granite aggregates, shelter independent programmatic functions. Their architecture intends to signal to the visitors on entering the gardens, the particularity of the building and its dedication to nature.

Patios, between the buildings and greenhouses, contribute to the free-flowing arrangement of volumes and create a sequence of perspectives.
