The project by EMBT for COPAGRI within the Expo Milano 2015 stems from the combination of two single domes of equal diameter, but different heights. The two domes together create a flexible and well-structured space that could be further subdivided in order to fit different needs of the internal spaces. The double dome consists of an “origami” of structural glulam elements, joined by steel plates.
The dome is conceived as a variation of the vast surrounding public space: for this reason, the structures present clear permeability and full congruence with the setting. The open nature of the structure is materialized in a reduced use of mechanical systems, in favor of natural lighting and natural ventilation.
The structure is composed of a big three-dimensional grid that gradually transforms in woven branches, as it grows to the open top of the dome. The structural elements become architectural ones, designing both the internal and the external facades as tree branches; the empty spots of the grid enhance air and light permeability, together with visual continuity between outside and inside.
The double dome is a prefabricated structure, made of spruce glulam with zinc-coated steel joints. Numerical control machines cut the structural elements, and they can be easily assembled and dismantled in agreement with COPAGRI’s need of reuse after the Expo, as expressed by the project competition requirements.
