The Hammond House is an historic house located at 9 Old Orchard Road in the village of Chestnut Hill in Newton, Massachusetts. With an estimated construction date of 1645-1730, it is believed to be the oldest house in Newton. It is also a rare example of a First Period house that was started as a single cell (three bays with chimney behind one bay), that was expanded to five bays later in the First Period; such expansion usually took place later in the 18th century, during the Georgian period. The house has been extended multiple times over the intervening centuries; the original core now lies just east of the main entrance.[1] The original house was built by Hon. Ebenezer Stone when he moved from the Stone homestead at Mount Auburn in Watertown.[2]
The house was listed on the National Register of Historic Places in 1990. In the early 2020s the house was remodeled, a project that entailed removing most of the historic interior finishes and the creation of a non-historic contemporary aesthetic.[3]
