The Architect's Newspaper Blog website has reproduced renderings of Daniel Libeskind's planned residential condominium tower that is supposed to rise 54 floors above the 14-story office building at 1 Madison Avenue.

The renderings come from Libeskind's recently published book, "Counterpoint," and the website noted that a spokesman for the developer, Elad Properties, said that the images "were made at least a year ago, for publication purposes, and no longer reflect the current state of the project."

The article on the website includes four renderings, all showing the project "in full," as opposed to the "mid-section" detail that was published recently in an item by Justin Davidson in New York magazine. That "detail" picture, which was reproduced in this column yesterday, did not indicate where the proposed tower "addition" would be cited on the block and its visual relationship with the famous MetLife Clocktower on the same block that is being converted to residential use.

The renderings published November 18 in Mr. Libeskind's book indicate that the tower would rise at the eastern end of the 14-story, limestone-clad One Madison Avenue office building that is on the north side of 23rd Street and extends fully to Park Avenue South. The proposed tower would be setback slightly from the Park Avenue South frontage on the setback of One Madison Avenue. It would have a slanted roof.

In the website article, Libeskind refers to the addition as the "New York Tower" and an accompanying article by Matt Chaban said that "The tower, which would be the city's tallest residential structure, would rise adjacent to the iconic clock tower of the old Met Life Building," adding that "In a city with dwindling room to build - and a growing need for green amenities - Libeskind said the project offers a park-in-the-sky model for the future, with its bands of leafy terraces that ascend the building....Libeskind said that the project is being designed as-of-right, and will not need any special zoning changes."

The rendering published yesterday showed that the glass-clad tower would have curved facades, part of which would be "cut away" to reveal stepped balconies and multi-story columns supporting the top of the tower that "could top out just shy of 937 feet."

The famous, 700-foot-high MetLife Clocktower building, which was designed by Napoleon Le Brun & Sons in 1909 when it became the world's tallest building. It was modeled on the campanile in the Piazza San Marco in Venice.

Elad is the developer and it also has converted the former Gift Building at 225 Madison Avenue to residential condominiums and also has converted a large part of the Plaza Hotel on Fifth Avenue at 59th Street to residential condominiums.

Mr. Libeskind won acclaim for his 1999 design of the Jewish Museum in Berlin and subsequently was designated the master planner for the redevelopment of the World Trade Center site at Ground Zero.

The Clocktower's official address is 4 Madison Avenue and it has long been one of the city's iconic skyscrapers.

MetLife also built the massive, scalloped-sided, limestone-clad office building at 11 Madison Avenue on the block immediately to the north and it was originally conceived as an extremely tall skyscraper whose tall height was not completed due to the Depression. Its foundation and structure can still support an enormous "roof-top addition." Known as the North Building, it was designed by Harvey Wiley Corbett and D. Everett Waid.

It and the Clocktower direct overlook Madison Square Park as does another residential skyscraper now nearing completion, One Madison Park, on the south side of 23rd Street at the foot of Madison Avenue. One Madison Park is a slender glass tower designed by Cetra/Ruddy.
