New York's 'skinniest house' sells for $2m

A townhouse dubbed New York City's skinniest house has sold for $US2.1 million ($A2.27 million).

The red, 3m-wide, 12m-long brick building in Greenwich Village was built in 1873 on land used as an alley between homes.

The townhouse was listed for sale last August at $US2.7 million.

The two-bedroom, two-bathroom home last sold in 2000 for $US1.6 million

A plaque on the narrow Bedford Street home notes that poet Edna St Vincent Millay once lived there; as did anthropologist Margaret Mead.
