Peter Pennoyer and Sam Roche have recently unveiled a counterproposal for expanding the New York Public library that preserves the stacks intact and extends the library underneath the Terrace in Bryant Park. Many will be caught up short by the architectural style of the addition which is as unlike the Foster + Partners proposal as oil and water. Critics of the Foster design likened its slick but characterless atmosphere to that of a chain bookstore. Well, the Pennoyer/Roch design certainly doesn’t look like a store, unless it is the late-lamented Scribners Bookstore on Fifth Avenue. More important is that the scheme shows a alternative strategy to enlarging Carrère & Hastings’ masterpiece. Building beneath the Terrace, and adding a floor to the existing stacks beneath the park itself, creates a total area for the entire library of 873,000 SF, compared to only 593,000 SF in the Foster scheme. This exceeds the current total area of the Schwarzman Building, the Mid-Manhattan Library, the Science, Industry and Business Library, and the Bryant Park Stacks (808,000 SF). The cancellation of the Foster proposal opens the door to more such innovative thinking.
