Indeed, the former five-story office building is being converted to residences. Oh, not just the existing five floors -- developer Ron Shoshany is adding 14 stories to the structure. Work was approved for this spot in September 2004.
In any event, we just can't imagine how this is going to look... aside from really out of place. For starters, 65 Liberty Street next door is the former Chamber of Commerce of the State of New York. (Now home to the International Commercial Bank of China.) It's a A Beaux Arts landmark erected in 1901. A faux-op for next door then.
By the way, Joseph P. Day, real estate auctioneer and broker, bought 67 Liberty for his business in July 1919.
UPDATE: I found a rendering over at Newman Design.

As the copy there reads:
"Located in lower Manhattan, 67 Liberty Street Condos is a 19 story luxury residential rental building. The property was converted from a five-story commercial building into a 19 floor residence through creative application of zoning regulations. The design plan retained the skin on the first five stories, thus preserving the existing zoning, setbacks and utilizing the maximum FAR. As a result of the building’s narrow architecture, an interior scissor stair was designed."
