From the article (see the sidebar):
"There are four sets of guidelines," said Stevenson.
"Preservation, which is stabilizing and keeping the components of the building as they are in this moment in time.
"Restoration, which is when you pick a period to take your building back to; for a museum-quality restoration, you would take your building back to 1880 and take away modern additions and that sort of thing.
"Rehabilitation, which is the most common thing that is done; you preserve the historic character and features, but you make it workable in today's environment and make some interior changes. You might renovate some spaces and change the use.
"Reconstruction, which is when you have enough evidence to rebuild something that has disappeared.
The Crocker Church and Bidwell-Wood structures in Sarasota will be restored to a specific time period (to be determined).
