DISTRICT
In the District Data Sheets attached to this
nomination, vernacular houses have been described by their floor plan;
stylistic designations have been used only for those buildings that possess individual
decorative details derived directly from high-style architecture at the time of
their installation. Numerous
timber-frame buildings have undergone alteration by the removal and replacement
of their original chimneys; in these cases such buildings have been described
by their apparent original plan (if exterior evidence exists) or merely as
timber-frame vernacular if their original plan is unclear due to later
alterations.
Since most buildings in the District do not have
identified historic names, this category on the Data Sheets has been left blank
in the cases of buildings constructed as free-standing single-family houses;
other unnamed buildings have been identified by building type, specifically,
double house, row house, apartment house, commercial block, school building and
fire house.
The contributing status of structures has been
assigned based on the retention of pre-1930 designs. Buildings, which clearly major
identifiable elements of their original (pre-1930) designs, have been designated
as contributing [C].
Structures which appear to pre-date 1930 and which are similar in scale
and materials to their neighbors, but which have undergone major alterations
such that their period of origin cannot be readily determined, have been designated
as minor contributing structures [MC]. Finally, those structures
built after 1930 have been designated as intrusions [
