Just found this place being advertised by Corcoran – http://www.corcoran.com/nyc/Listings/Display/2586025.
It’s classified as S1 (single family + Store). It’s also listed as a single family on the Corcoran site but it’s listed as a multifamily on Streeteasy – http://streeteasy.com/nyc/sale/876507-multi-104-roebling-street-williamsburg-brooklyn.
There are photographs showing at least 3 separate kitchens and the Corcoran description reads -
Single Family Brick Townhouse w coffee shop,finished basement and 4 income producing apartments translates to real estate perfection.
