This paper proposes the use of bio-inspired cellular growth simulations as an architectural computational design tool. A set of cells, which behave similarly to particles, are programmed to divide in order to generate larger geometric accumulations.

Two types of growth systems were investigated: The first type maintains connections of cells to form a manifold topology. Connections are updated at cell division, and a division of the inner cells causes the accumulation to expand and bulge out. The second type is a growth with a floating topology in which the cells can freely rearrange. A division of the peripheral cells causes a marginal growth of the accumulation.

The two systems were tested in the design of two permanent interior installations in an office space. Both simulations could successfully be applied to construct the installations, achieving the functions of atmospheric lighting, integration of ceiling and furniture, and complex yet coherent design quality. Although the algorithm is in its infancy, it shows a potential for further refinement as a design tool.
