The Building at 104-106 Hancock Street is an historic cottage at 104-106 Hancock Street in Cambridge, Massachusetts. The 1-1/2 story wood frame cottage was built in 1839 for Isaac Livermore on land once belonging to Judge Francis Dana, and was among the first to be built after Dana's old mansion burned down. The cottage is basically Greek Revival in form, but has Gothic Revival features, including a lancet-arched louver in the side gable. It is similar stylistically and in date of construction to the Ephraim Atwood House, next door at 110 Hancock Street.
