No matter that Alexander Hamilton’s country home, the Grange, is 206 years old. Until now, it had been in a perfectly contemporary Manhattan real estate bind: not enough space.

What to do? Move, of course.

So on Saturday, the two-story, 298-ton wood-frame house will be rolled conspicuously — and slowly — from its cramped site on Convent Avenue to an appropriately verdant new location a block away in St. Nicholas Park, facing West 141st Street. That is as close as it can get these days to the rural setting for which it was originally designed.

Once new foundations are completed, a yearlong, $8.4 million restoration and reconstruction will undo decades of unsympathetic alterations to the house, known formally as the Hamilton Grange National Memorial.

Stephen Spaulding, chief of the architectural preservation division in the National Park Service’s Northeast region, said the 500-foot move on Saturday should take three to six hours.

But in a sense, the journey has taken almost half a century. In 1962, President John F. Kennedy authorized the Interior Department to assume ownership of the house on the condition that it be moved to a suitable location.
