Aggregative Tower





Aggregative Tower


Location: Shanghai

Area: 155 000sqm

Year: 2012


Shaped as an Aggregative Tower, the study for ABC Art Bund Center in Shanghai encloses a network of relationship between spaces, paths and scales.

The system arranges multiple programs in a sequence of open spaces, sloping paths, and floors that together form a continuous exploration of the possibility of the space.

The project includes art district, ateliers, museums, workshops, academy, exhibition spaces, performance halls, libraries, leisure spaces, bookshops, covered and open-air squares connected with the underground system. The structure is shaped using an essential relationship between space, scale, and path:


The square is an empty space full of potential activities, as a space that can be accessed from all direction. In this system anything can happen, as on a stage without scenery, exposed and full of potential, challenging the old method of assign strictly defined functions to space.


Single elements inside the empty space shape the paths and direct the crowd toward the inside of the tower. The underground area is connected to the outside with both physical and visual connection. As a reflection of the outside, the underground is shaped using the continuity of the external elements inward, reversing the logic of the part in an empty place inside.


The higher grade of complexity is the result of the junction, an overlapping composition finalized to evolve its use, where the influences melt and generate integration between elements. In this condition, the un-clear composition is filled with possibilities and attractive complex structure, continuing the exploration inside.


The generated space, surrounded by frames, physical and immaterial barriers represent the spatial bubbles that delimit small realities and creating a small-scale bigness. This is translated into the creation of human-scale spaces, connected to form a sense of unity.


The center is an empty void defined by floor-to-floor ramps and stairs along the perimeter inside, creating a connection between levels. Two central vertical links start from the ground to connect the levels and support the structure in the internal and external void. The elements compress the space inside, and the ramps define the continuity of the path without interruptions, enhancing interrelation between areas with diagonal slab, free plans and creating a continuous exchange between programs, and increasing physical and visual connections, exploring series of new relations.

Absolute space:

The union of many small situations gives the bigness, and the last evolution of the space is the return to a single element and the repetition of a defined and regular shape that multiplies and repeats the same type of space.

The design is abstracting from any substance, bringing a picture of evanescence.
