Block Hall progress
By Carter Horsley   |   From Archives Tuesday, July 5, 2005
Scaffolding now fully surrounds Block Hall, the 7-story Tudor-style building at 21-23 South William Street, that is being converted to about 30 luxury condominium apartments.

Originally erected as a private club, the building at one time was occupied partially by the Italian Alps Restaurant. It is on a handsome street that also houses the very impressive Banca Commerciale Italiana and the Wall Street Inn. The building also fronts on Stone Street, an official historic landmark district of 19th Century buildings, many of which house restaurants and caf?

When completed, the building will have a rooftop garden and a fitness center. Its apartments will have high ceilings and appliances by Viking, Miele and Liebherr.

The building was acquired in early 2004 for about $4.5 million by the Kennelly Development Company from the Block Hall Development Company. The 25,000-sq. ft. building had been owned since 1967 by John Herzog, who in 1988 founded the Museum of American Financial History.
