He went to Wilmington, North Carolina, in 1839, where he first supervised construction, and then received his first independent commission to design the Wilmington Custom House in 1843.

This led to numerous commissions in Savannah, including the Andrew Low House, the Mercer House, Massie Common School House and the Green-Meldrim House.
