The Lucas–Johnston House (also known as Augustus Lucas House) is an historic colonial house in downtown Newport, Rhode Island.
History of building
Dendrochronology surveys were conducted on the house showing that the trees felled in its constructed were from Circa 1650, Summer 1714, and Winter 1759/60. An architectural and dendrochronology study concluded that
"the house has two interior chimneys, but they are placed front to back rather than side to side [as was normal in eighteenth century Georgian style houses]... the rear chimney, with its kitchen fireplace, is the one with more age. The foundation walls appear to be of one unified build rather that parts of an earlier building combined with a later construction. Exterior walls, particularly on the north and west walls are studded construction and also have brick nogging. Both of these techniques are quite uncommon for Newport...There are a couple of strange datings ranging from 1618 to 1634...while nothing dating from the first quarter of the 18th century shows in the results, with the exception of a single felling of 1714."[2]
