The Clock Building being constructed in the northeast quadrant of Public Square is expected to be complete by the end of October and be open by Jan. 1, the developer said.
The brick portion of the building will be painted a sandy buff color called old bone, said developer Kurt Cushwa.
Once complete, the Clock Building will wrap around the corner, including 6-8 E. Washington St., an already-existing building.
Cushwa said the new brick portion will be painted to keep it historically accurate with other 1830s buildings in the square.
It wasn't until around 1910 that brick buildings were no longer painted because they were being made more rigidly with portland cement mortar, Cushwa said.
In the 1830s a lime mortar being used made the brick softer so it needed to be stained to make it water resistant, he said.
