Library Delft University of Technology | Mecanoo

Delft University of Technology (TU Delft) commissioned Mecanoo to design a library that would be the heart of the university and give a face to a campus the size of a city district. The iconic library of TU Delft, designed with the digital transition in mind, still meets expectations more than two decades after its opening.

A vast lawn opposite the Brutalist concrete auditorium is tilted at one point; the library slides into the resulting space underneath. A cone, the symbol of technical engineering, pierces the lawn and library, attaching them like a pushpin. Landscape, library and auditorium form a new unity becoming the preferred meeting place on the TU Delft international campus.

Upon entering, visitors are drawn to the impressive wall of books that hangs in front of an expansive deep blue background. The columns in the central space not only support the structure but also provide heating and ventilation, and illuminate the continuous metal ceiling that flows across all spaces.

Daylight enters the building through the climate-controlled glass facades, as well as through the cone whose base forms the focal point of the central space. Moreover, the cone shapes different reading rooms on the upper floors.
