It comes as no surprise that the
Shakers, who were so fastidious about order and practicality, would invoke those
same ideals when designing and planning their communities. The main buildings at Pleasant Hill were
built perpendicular to each other with those used as communal dwellings oriented to maximize the southern exposure.
At Pleasant Hill, an evolution took
place in the architectural style. Early
buildings dating to ca. 1810 have the typical horizontal proportions and the
small, boxy, widely spaced windows of
the Western Shaker vernacular. While shop buildings continued to be constructed
in this style at Pleasant Hill, subtle high-style Federal influence appeared in
the communal dwellings at an early date. Several communal houses built from
1816 to 1822 at Pleasant Hill have tall, vertical, closely spaced windows, giving
the houses more of the feel of the high style Federal aesthetic.
By 1824, Micajah Burnett, a Shaker
builder and engineer at Pleasant Hill, was experimenting with Federal architectural forms that included
high-style Adamesque elements. Pleasant Hill shop buildings continued to be
built in a plain, conservative style with small widely spaced windows well into
the 1840s. At the same time, Burnett’s designs for dwellings took on more grand
and worldly Federal architectural features. Pleasant Hill buildings with these
features include the fourth Center Family House (1824–1834) and the Trustees’
Office (1839–1841). These two buildings have features like arched and
three-part windows, mullioned fanlights, sidelights, balustrades, interior
barrel vaults, and other graceful ornamental features typical of the Federal
style.
