Rocane never had zoning laws regulating building heights, so the 1920's setback-style originating from New York as an answer to such laws was adopted in Rocane for purely appearance reasons. The first building representing this style was the 30-story Kansas Bank Building behind the St.Matthews Church and the Old Cemetery. The Kansas Bank Building was constructed in 1922 and with its height of 381 feet (116 m) it was the first building in Rocane to break the 100 meter mark. It was Rocane's tallest building from 1922 to 1929.
The most important lot available for commercial use, the northeast corner of Main and Market streets, was occupied by a 5-story building from the early 1870's. It was owned and used by the Rocane Board of Trade. By 1920's that building was utterly outdated and far too small for the Board of Trade of Rocane's bustling commerce. In 1922 that building was torn down and work began on a new Board of Trade building. Work was completed 1924 and the Adler Building had a new neighbour standing at 249 feet (76 m) with 20 stories. Building was named the Hood Building in honor of the founder of Rocane Board of Trade, Robert Hood.
