Portland Public Services Building, Portland, U.S. —
This 15-storey municipal office block was completed in 1982, but due to structural problems it already needs renovations to the tune of $175 million. An early example of post-Modernism in a major city, it attracts diverging opinions, with many supporting its proposed demolition to make space for something new entirely. Yet, in 2011, it was included in the U. S. National Register of Historic Places.
