Gabriel Manigault, a rice planter who studied law in London for a short time in 1777, became Charleston's most accomplished amateur architect. He introduced the Adam style to Charleston which brought curved walls, elaborate plaster work, and new color schemes, like bright blues, yellows, greens, and pinks. He designed elegant houses for himself and his brother Joseph, the hall for the South Carolina Society, a building for a branch of the First Bank of the U.S. (now Charleston City Hall), and the Chapel of the Charleston Orphan House.
