Santo Spirito, started around 1434 and finished in 1482, was designed by Brunelleschi. This church follows the basic Latin cross plan, as did S. Lorenzo. However, there are some differences in the two churches. Santo Spirito has more of a sculptural feeling, the side chapels are more open, they also have columns and pediments. Instead of using pilasters for the niche wall Brunelleschi has put in Corinthian columns. The ceiling is flat, with octagon like patterns while S. Lorenzo has square coffers.
