Typical of the early architecture of the colonial period, the construction of the Jonathan Green House is functional and straightforward.

[4] When originally built, the house would have been located near the seventeenth century borders of Charlestown and Malden, Massachusetts, in what is now Stoneham.

Pairs of pin holes in the front girt indicate the use of single-story studs and earlier, possibly asymmetrical, window placement.

[5] Currently, the main block is two and a half stories high, five bays wide, and one room deep, with a central chimney, a granite foundation and clapboard sheathing.

The centered entrance had been framed by simple pilasters and topped by a modest entablature (no longer extant).
