When foundation was dug, and then a cast-iron sill was set into a base. A hollow, cylindrical column, were box columns with a core selection the heaviest rolled columns, was bolted perpendicular to the sill, When a pair of adjoining post was in place, a lintel was bolted to line them. The process continued horizontally and vertically, floors were laid, and a new style of building resulted. Interior spaces were a series of self-contained boxes, each an island, entire of itself. Since the units were self-supporting, there was no need for thick walls to support the load of the building, as a result, large expanses of windows punctuated by delicate cast-iron columns created a rhythmic balance outside and well-lit spaces inside.
