One of the most commonly found styles in Colorado residential buildings after
1900, the Foursquare is easily recognized by its square plan and overall simplicity.
The majority of these houses were built during the first three decades of
the 20th century. The typical Foursquare is a two-story hipped roof structure
with central dormer, minimal decoration, broad overhanging eaves with brackets
or modillions, classical frieze with dentils, and a porch with hipped roof
supported by simple Doric columns or square posts. Occasionally, a Foursquare
will feature a shaped gable or will be considerably larger with more elaborate
ornamentation. But, in each case, the basic square plan is predominant.
Here are some designated landmarks in Longmont that are representative of
the Four Square style.
