Mónica Ponce de León of Office dA discusses her projects in terms of precision, and geometry. Her office poses the questions: What does it mean to build a building with zero tolerance? How does one achieve precision or the image of precision? How is precision present or absent in an architectural project? For de Leon, both the problem and solution are constructed through geometry.

Ponce de León describes several projects including CNC routed filing cabinets, a carbon fiber table, the Toledo House, and the Witte Arts Building, the Tongxian Art Center, and an intervention at the Mantra Restaurant, "Fabrications" (an installation at MOMA), their proposal for the P.S. 1 Urban Beach competition, and their design for Upper Crust Pizzeria in Boston.
