Historic (Preservation)

From an almost $40 million restoration of Alfred I. du Pont’s mansion and garden to painstakingly restoring a state capitol building’s ornate dome to renovating a museum listed on the National Register of Historic Places, Wohlsen’s craftsmen are able to make today’s work look just like it was done more than a hundred years ago.
