••• There is (was?) a Post-it war happening on Canal Street between two ad agencies, Havas Worldwide and Horizon Media. You can see a bunch of examples at #canalnotes; the above photo is by @kBostley. —NY1

••• Design charrette for the Water Street arcades: “The Architect’s Newspaper strongly believes these public spaces have great aesthetic, financial and practical value, and should remain public amenities. If the Amendment is approved, the door would be flung open for developers to make similar land grabs of similar spaces across New York City, all on the spurious claim that the spaces are somehow imperfect. To ensure that everyone will have opportunity to consider the full value of these spaces, AN invites all members of the public to participate in a design charrette to recommend creative ways to use the arcades and adjacent plazas that surround the perimeter of 17 buildings along Water Street in the Financial District. The recommendations will be presented to the City Council in June 2016.”

••• “At this weekend’s World Bboy Battle, an extreme break-dancing tournament, hundreds of dancers from across the world will contort their bodies into pretzels, spin on their heads and catch air at heights that will make you nervous. […] Tickets are still available for Sunday’s championships, in which the top 16 participants will compete, at Tribeca Performing Arts Center. 3 p.m.” —New York Times

••• “This Sunday, May 15th at 8am, Dr. Stein Hoff will begin his attempt at rowing across the Atlantic, 120 years after George Harbo and Frank Samuelsen.” The rest of the Broadsheet article is about Harbo and Samuelsen.

••• The latest building to go under his microscope of Daytonian in Manhattan, who has been on a Tribeca tear, is 97 Chambers. “One of the first of the high-end residences on Chambers Street between Broadway and Church Streets to succumb to commerce was the mansion of Dr. David Hosack at No. 97. The doctor, deemed by The New York Times as ‘one of the most skillful and widely known of New-York physicians,’ had been the attending physician at the duel between Alexander Hamilton and Aaron Burr in 1804. Dr. Hosack’s ‘magnificent’ mansion and property ran through the block to Reade Street. In 1857 his estate demolished the house and began construction on a modern loft building—one of the first in the formerly exclusive neighborhood. The unknown architect designed a five-story Italianate structure faced in sandstone. The elegant façade featured classic pediments over the openings and Palladio-inspired grouped windows at the center of each story. A pressed-metal cornice with foliate brackets crowned the structure.”
