Worcester Investments, a family-owned company based in Riverside, will seek a property tax abatement for its planned $43 million conversion of the nine-story Executive Plaza Office Building — aka "the Flashcube Building."

Even the names given the period and style of American architecture — modern, mid-century modern, international — seem to contradict the concept that such buildings could be “historic.” Many were built to replace, and in reaction to, the brick and stone structures that dominate historic registers.

Demolition began Monday night, and continued Tuesday morning. The site was once home to several business, most recently Flower's By Jerry, and a gas station a very long time ago. Soon, it will be a six-story building with 92 apartments, and have a ground floor retail space.
