A couple in Chicago bought a 19th-century church and turned it into a private home and event space for the community.

Jacoby said this is his favorite space in the house because of the elements that still remain. The altar, for example, still has the original fresco, which is painted onto a canvas and then hung on the ceiling. Plus, there are two stained-glass windows that hint at the building's past.

The best part, Jacoby said, is seeing people react to the space.

"We love seeing the home through other people's eyes," he said.
