london-based architects anthi grapsa and konstantinos chalaris's design proposal for
the 'piraeus tower 2010' competition incorporates plant nurseries into the skin of the abandoned
tower. the brief called for a new interpretation of what a facade can be and do.

at only 2 squared meter of green space per person, 'engineered biotopes' recognizes the lack
of open green space in the city of piraeus. the design uses modern agricultural techniques in
the construction of the tower, essentially becoming a vertical park for not just the inhabitants
but the dwindling species of birds and wild flora. the first two stories accommodate a grid of
glass tubes that nurture seedlings. from a distance, this portion of the tower provides a shimmering
effect, reflecting light onto nearby streets. from floors 3-22, a system of small biotopes house
small vegetation along the surface of the facade. depending on the weather conditions,
each individual modules can be re-positioned by a robotic crane to optimize on sunlight
and water consumption. this continual activity on the tower's facade creates an urban choreography
that establishes a dynamic relationship to the piraeus port where containers and ships are constantly
reconfigured.
