An organism which lives in or on another organism (its host) and bene ts by deriving nutrients at the other’s expense.

Origin: mid 16th century: via Latin from Greek parasitos ‘(person) eating

at another’s table’, from para- ‘alongside’ + sitos ‘food’.

Our parasitic architecture can be de ned as an adaptable, transient

and exploitive form of architecture that forces relationships with

host buildings in order to complete themselves.

Parasites cannot sustain their own existence without siphoning

energy and structure in this case from the surplus supply

demonstrated in host buildings.
