The Standards are neither technical nor prescriptive, but are intended =
to promote responsible preservation practices that help protect our =
Nation's irreplaceable cultural resources. For example, they cannot, in =
and of themselves, be used to make essential decisions about which =
features of the historic building should be saved and which can be =
changed. But once a treatment is selected, the Standards provide =
philosophical consistency to the work.=20

The four treatment approaches are Preservation, Rehabilitation, =
Restoration, and Reconstruction, outlined below in hierarchical order =
and explained:=20

The first treatment, Preservation, places a high premium on the =
retention of all historic fabric through conservation, maintenance and =
repair. It reflects a building's continuum over time, through successive =
occupancies, and the respectful changes and alterations that are made.=20

Rehabilitation, the second treatment, emphasizes the retention and =
repair of historic materials, but more latitude is provided for =
replacement because it is assumed the property is more deteriorated =
prior to work. (Both Preservation and Rehabilitation standards focus =
attention on the preservation of those materials, features, finishes, =
spaces, and spatial relationships that, together, give a property its =
historic character.)=20

Restoration, the third treatment, focuses on the retention of materials =
from the most significant time in a property's history, while permitting =
the removal of materials from other periods.=20

Reconstruction, the fourth treatment, establishes limited opportunities =
to re-create a non-surviving site, landscape, building, structure, or =
object in all new materials.
