Derrida had a direct impact on the theories and practices of influential architects Peter Eisenman and Bernard Tschumi towards the end of the twentieth century. Derrida impacted a project that was theorized by Eisenman in "Chora L Works: Jacques Derrida and Peter Eisenman". This design was architecturally conceived by Tschumi for the Parc de la Villette in Paris, which included a sieve, or harp-like structure that Derrida envisaged as a physical metaphor for the receptacle-like properties of the "khôra". Moreover, Derrida's commentaries on Plato's notion of "khôra" (χώρα) as set in the "Timaeus" (48e4) received later reflections in the philosophical works and architectural writings of the philosopher-architect Nader El-Bizri within the domain of phenomenology.
