To celebrate the start of a seven-month land use review process, Cornell has released preliminary renderings of the first academic building planned for Cornell Tech – the new world-class technology and entrepreneurship campus in New York City that was masterplanned by Skidmore, Owings and Merrill (SOM).

The modern campus strives to rethink academic workspace, prioritize environmental performance, and exploit the unique urban condition of Roosevelt Island. In May, Pritzker Prize laureate Thom Mayne, founder of Morphosis, was appointed as architect of the first landmark building, which will set the stage for the carbon positive campus.

The Rudy Bruner Award for Urban Excellence (RBA) recently launched their 2013 call for entries for their biannual competition which celebrates urban places that are distinguished by quality design and their social and economic contributions to our nation’s cities. The program has continuously served as a catalyst for its winners, advancing their work on both the local and national levels. Excellence exists in every city. It can be found in downtowns, in neighborhoods, in small cities and large ones. These places often transcend the boundaries between architecture, urban design, and planning. They are born through processes of transformation – the renewal of something old, or the creation of something new that resonates in the history of community life. The deadline for submissions is December 10. For more information, please visit here.

A simple gesture like opening the pages of a book became the inspiration for Ghirardelli Architetti in their design proposal for the Daegu Gosan Public Library Competition. By interacting with their intellectual awareness, art, science and history, this can transform into a different state of being, separated from what is happening around us in where we discover leisure, tranquility and food for thought with infinite horizons to explore inside and outside ourselves. Their library design contains this knowledge and makes it available through intriguing spaces and activities, providing at the same time, individual detachment from the daily ritual.

Watch as JA+U takes a close look at the Jun Aoki House at Hanegi Park designed by Japanese architects Shigeru Ban Architects. The short video tours viewers through this intimate and minimalist home, revealing the nuances and features of the design. The house has a number of unique features, the most prominent of which is the semi-arched roof vault on the second level, which also gives a penetrating view through the length of the house. The openness of the architecture is emphasized by the austerity of the material choices. Stark white walls are set against the lush trees and vegetation of Hangei Park, highlighting the contrast between the natural and man-made.
