Re-creating the appearance of visible features of
the historical structural system, such as post and beam
systems, trusses, summer beams, vigas, cast iron columns,
above-grade stone foundations, or loadbearing brick
or stone walls. Substitute materials may be used for
unexposed structural features if they were not important
to the historic significance of the building.
The interior of the Hall of the Governor's Palace in Williamsburg, Virginia,
was re-created in its entirety, including decorative
features and finishes.

Re-creating a historic floor plan or interior spaces,
including the size, configuration, proportion, and relationship
of rooms and corridors; the relationship of features
to spaces; and the spaces themselves.
Duplicating the documented historic appearance of
the building's interior features and finishes, including
columns, cornices, baseboards, fireplaces and mantels,
panelling, light fixtures, hardware, and flooring; and
wallpaper, plaster, paint and finishes such as stencilling,
marbling and graining; and other decorative materials
that accented interior features and provided color,
texture, and patterning to walls, floors and ceilings.
Installing modern mechanical systems in the least
obtrusive way possible, while meeting user need.
Installing the vertical runs of ducts, pipes, andcables
in closets, service rooms, and wall cavities.
Installing exterior electrical and telephone cables
underground, or in the least obtrusive way possible.
Changing the documented appearance of visible features
of the structural system.
Altering the documented historic floor plan or relocating
an important interior feature such as a staircase so
that the historic relationship between the feature and
space is inaccurately depicted.
Altering the documented appearance of interior features
and finishes so that, as a result, an inaccurate depiction
of the historic building is created. For example, moving
a feature from one area of a room to another; or changing
the type or color of the finish.
Altering the historic plan or the re-created appearance
unnecessarily when installing modern mechanical systems.
Installing vertical runs in ducts, pipes, and cables
in places where they will intrude upon the historic
depiction of the building.
Attaching exterior electrical and telephone cables
to the principal elevations of the reconstructed building,
unless their existence and visibility can be documented.
