One of the oldest extant homes in Wilton Center is this Revolutionary-era Georgian house. The home was likely built in the 1770s and has a sloping saltbox roof at the rear. The house was the property of the Blanchard Family to this day. The house shows the more rural, vernacular Georgian style common in small towns in New Hampshire from the 1700s.

what is that roof type of structure over the front door?
It does not look like it is part of the original house.
Can you enlighten me?

Good eye! The little entry portico looks to have been added in the late 19th or early 20th century. About the time when Wilton was becoming a summer cottage/home destination for the natural scenery and clean air
