At 10 stories high — with the capacity to support 10 more floors — and 500,000 square feet, the Ellicott Square Building was the largest office building in the world for the sixteen years after it opened in 1896. The building was named after Joseph Ellicott, planner for the Village of New Amsterdam, now the City of Buffalo. It was built at a cost of $3.5 million in less than one year.

The mantra of architect Daniel Burnham was "make no little plans, they have no magic to stir men's blood; think big." Built in the Italian Renaissance style, the exterior of the Ellicott Square Building is made of granite, iron and terra cotta with a veneer of pearl gray brick. The majestic interior courtyard contains a marble mosaic floor designed by William Winthrop Kent. Imported from Italy, the 23 million pieces of marble on the mosaic depict sun symbols from civilizations around the world.

There are broad stairs on either side and a glass roof in an ornamental steel frame provides natural light. The building features ornate globe lamps, intricate columns, carefully proportioned classical features gracing doorways, marble and brass to trim iron and stone.
