UC roofs slanting down from the left, LC roofs slanting down from the right. To have pointed roofs on words use 1 UC followed by 1 LC ; if you want words covered by a 'typical' factory roof-look of the industrial past use only UC or LC.

Numbers, symbols and puctuation buildings are shorter and their roofs slant in both directions from the center; their lower roof corners join any other lower roof corner.

Word space is just that, if you want some decorative item to show gaps or word space use some of the designs shown on symbols, or use the underscore moon. The hanging lamps and sign scrolls are designed to fit on the taller sides of a letter unit.
