Planning fallacy
The Sydney Opera House was expected to be completed in 1963. A scaled-down version opened in 1973, a decade later. The original cost was estimated at $7 million, but its delayed completion led to a cost of $102 million.
Woodstock Opera House
Erected in 1889, the Opera House was designed and constructed by Elgin-based architect Smith Hoag at a cost of $25,000. The construction materials are mostly of local origin including limestone, terra cotta, fieldstone, white brick, and sandstone. Its architectural style is a mixture of late Victorian-era tastes combined with Early American, Midwestern, Gothic, and even Moorish elements. The interior is modeled after the showboats of the time, with dimensions and decorations that imitate many of those grand floating theatres.
