Work began last Friday on the Timber Shed, one of two Admiral’s Row buildings that were slated to be preserved under a 2009 agreement between the federal government and the Brooklyn Navy Yard Development Corporation. (The other nine historic buildings are heading for the scrap heap.) After being reinforced back in 2011, the historic structure lay fallow while plans for a large adjacent supermarket fell apart under a cloud of scandal and got put back together again. More recently, there have been some questions about whether the shed was beyond repair. Andrew Kimball, president of the Navy Yard, assures us, however, that it will be preserved and the removal of bricks is just a part of the stabilization process. The stabilized structure will ultimately be handed over to the developer, Blumenfeld Development Group, who will perform the restoration to national preservation standards that will make them potentially eligible for historic tax credits.
