Pillot Building, Historical building in Houston, United States.

The Pillot Building at 1006 Congress Avenue is a replica completed in 1990 of an 1857–1869 commercial building erected by Eugene Pillot. Its cast iron front, a feature of the original, is partly built from original columns, sills and lintels. The two-storey facade stands in Downtown Houston.

Eugene Pillot (1820-1896) built the structure between 1857 and 1869 at 1006 Congress Avenue, and it was listed on the National Register of Historic Places on June 13, 1974. After severe damage in the 1980s, it collapsed during reconstruction in 1988. A replica incorporating some original cast iron columns, sills and lintels was completed in 1990 and removed from the National Register in 1994.

The building's name comes from Eugene Pillot (1820–1896), who built it between 1857 and 1869; its cast-iron front was a talking point in a city of brick and timber. Tenants over the years included a dry goods merchant and professional offices, so the address mixed retail and desk work in one structure.

The replica stands at 1006 Congress Avenue in Downtown Houston, on the same site as the original. It is a street-facing facade, so it is seen from the sidewalk rather than entered. Look for the cast iron columns, sills and lintels reused from the 1857-1869 building.

When the building collapsed, reconstruction workers carefully salvaged materials from the original structure to use in rebuilding. This effort to recover and reuse original components helped restore the building while honoring its past.
