Unfinished building is Antoni Gaudí's Sagrada Família in Barcelona, a church that has been under construction since 1882, and that is now expected to be complete in 2026. There are numerous unfinished buildings that remain partially constructed in countries around the world, some of which can be used in their incomplete state but with others remaining as a mere shell. Some projects are intentionally left with an unfinished appearance, particularly the follies of the late 16th to 18th century. Some buildings are in a cycle of near-perpetual construction, with work lasting for decades or even centuries. Antoni Gaudí's Sagrada Família in Barcelona,
Church of the Incarnation, Episcopal (Manhattan) 20, 1865. The church rectory was constructed in 1868-69, designed by Robert Mook. Except for its tower and walls, the building was destroyed by a fire which began on March 24, 1882. It was rebuilt and enlarged by David Jardine, with a spire added in 1896 by Heins and LaFarge following Jardine's designs. In 1905-06 the church rectory was rebuilt and received a new facade in neo-Jacobean style designed by Edward P. Casey. It is now the H. Percy Silver Parish House. The building was designated a New York City landmark in 1979, and was added to the National Register
