Storefront

A storefront or shopfront is the facade or entryway of a retail store located on the ground floor or street level of a commercial building, typically including one or more display windows.

[citation needed] Modern storefronts with display windows developed at mid-century after architectural cast iron became widely available and glass manufacturers began producing large panes of glass at relatively low cost.

[3] Also architects started to experiment with iron columns and lintels at the ground floor level.The combination of these two achievements led to the storefront as we know it today.

[4] The storefronts of commercial buildings are often substantially altered even when other architectural elements remain intact.

[2] Storefronts can also have an area in front of the unit called a "pop-out zone", which is about 500-1000 mm deep.
