Colonial

One of the most frequently produced and enduring popular styles in America is the Colonial Revival style.  It can be seen in a seemingly endless variety of forms throughout the state and the country and still continues to influence residential architecture today.  Basically, the Colonial Revival style was an effort to look back to the Federal and Georgian architecture of America ’s founding period for design inspiration.  Less commonly, the Post-Medieval English and Dutch Colonial house forms were an influence on the Colonial Revival style.  This enthusiasm to explore the architecture of America ’s founding period was generated in part by the Philadelphia Centennial of 1876 celebrating the country’s 100th birthday.  This trend was further promoted by the Columbian Exposition of 1893, held in Chicago .

Like most revival efforts, the Colonial Revival style did not generally produce true copies of earlier styles.  Although, in the early years of the 20 th century (1915-1935) there was a real interest in studying and duplicating Georgian period architecture.  Generally, the Colonial Revival style took certain design elements—front façade symmetry, front entrance fanlights and sidelights, pedimented doorways, porches and dormers—and applied them to larger scale buildings.  These colonial era details could be combined in a great variety of ways, creating many subtypes within this style.  In the 1940s and 1950s a more simplified version of the  Colonial Revival style became popular for homes, usually featuring a two story building, a side-gabled or hipped roof, classically inspired door surrounds and windows, shutters and dormers.  Less common are examples of the Dutch Colonial Revival which are distinguished by a gambrel roof, and sometimes a shallow pent roof over the first floor.  Likewise, there are fewer examples of the Colonial Revival style with a second story overhang inspired by the form of Post Medieval English buildings.

The Colonial Revival style was also popular for public buildings, applying common achitectural details of the style to a larger form.  Colonial Revival public buildings include government offices, post offices, libraries, banks, schools and churches.

Sullivanesque

The Sullivanesque style was created by Louis Sullivan  (1856-1924), a prominent turn of the century  architect. Sullivan was educated at MIT and the Ecole des Beaux Arts in Paris and worked for premier Philadelphia architect Frank Furness, before moving to Chicago.    The Sullivanesque style developed in response to the  emergence of tall, steel-frame skyscrapers in the 1890s.  This new building type presented a new design challenge.  Sullivan’s approach was to use ornament and design to delineate a tall building into three distinct parts, an entry level with prominent window and door openings, a mid section with bands of windows with vertical piers, and a top with a highly decorative cornice, often featuring round porthole windows.  Sullivan applied classical design principals to these early skyscrapers.  His tripartite design was distinctive and elegant and shows the influence of the concurrent Art Noveau movement in the decorative panels using geometric forms, curving lines and Celtic inspired entwined patterns.  This elaborate form of ornamentation marks a building as Sullivanesque more so than any other feature.

While several of Sullivan’s early works were constructed in Philadelphia between 1849 and 1860, many of his best-known works are located in the Midwest.  Sullivan worked with and influenced many other significant American architects such as Frank Lloyd Wright,George Grant Elmslie, and William Gray Purcell.  The Sullivanesque style is an urban style, primarily  seen in large cities or regional centers.

Italian

The Italian Renaissance Revival style developed at the very end of the Victorian period of architecture. Like the Romanesque styles and other later classically-inspired styles, the Italian Renaissance Revival style looked to Italy and the ancient world for inspiration. This style developed in direct contrast to the medieval form and appearance of other popular styles of the time, the Gothic Revival, Queen Anne, and Shingle styles. This style and the earlier Italianate style both were modeled on the 16th century buildings of the Italian Renaissance. However, Italian Renaissance Revival style buildings are much closer stylistically to the original form than the Italianate style. This added authenticity was due to greater familiarity with the original buildings—via photographs versus pattern books—and advances in masonry veneering techniques that developed in the early 20th century.

The most predominant feature of this style is its imposing scale and formal design incorporating classical details such as columns and round arches and balustrades. This style can take several distinct forms, but all variations are almost always of masonry (usually stone) construction. One version of the style features a large rectangular building, usually three or more stories in height, topped by a flat roof with a crowning balustrade. Another common feature for this flat roof version of the Italian Renaissance Revival style is a rusticated stone first floor with upper floors having a smooth finish. Porch arcades and porticos are often seen in this  version as well. The other most common form of this style features a hipped roof, often of clay tiles, with broadly overhanging, bracketed eaves. This variation bears some resemblance to the Spanish Colonial Revival style (also known as the Mission style) which was popular in the same period. While having a similar form and tiled roof, the Spanish Colonial Revival style lacks the classical details like columns, pilasters and pedimented windows.

The Italian Renaissance Revival style was first popularized on the East Coast by architects such as McKim, Mead & White as early as the 1880s. This elegant style is seen mostly in up-scale, architect-designed buildings, such as mansions or public buildings. While many examples of this style can be found in Pennsylvania, it is most common in city settings. The 1920s-era State Office complex (North and South Office Buildings, Finance Building, and Forum Building), adjacent to the Beaux Arts State Capitol building in Harrisburg, is of this style.

PA Architecture High Victorian Gothic Style 1860 – 1890

Identifiable Features

1.  Linear decorative polychrome bands of brick or stone
2.  Masonry construction
3.  Stone quoins
4.  Pointed arch (Gothic) windows and doorways
5.  Steeply gabled roofs, often with cross gables
6.  Ornamental pressed brick and terra cotta tiles
7.  Patterned brick chimneys
8.  Corbelled brickwork
9.  Turret with conical roof

high

 

The High  Victorian Gothic style is similar to the earlier Gothic Revival style, but is a more heavier, more substantial version of the style.  The High Victorian Gothic style was used mostly for large scale public buildings like schools, churches, or government offices, but was sometimes chosen for mansions or homes of substantial size.   Always executed in brick or stone, High Victorian Gothic buildings  are distinguished by the use of polychrome bands of decorative masonry.   Stone quoins, pressed brick,  and terra cotta panels  were commonly used.  Windows and doors were accented with brick or stone trim, often in contrasting colors.   The Gothic pointed arch may be present  at windows, entrances, and decorative dormers and cross gables.  Round turrets with corbelled brickwork and conical roofs are common to this style as well.

The High Victorian Gothic style developed in England in  around the mid point of the 19 th century. English architect John Ruskin, author of “The Seven Lamps of Architecture” (1849)  was a major proponent of the style, finding “constructural coloration” superior to superficially applied color.  Initially, this style was inspired by  English medieval architecture, but later it drew from medieval French and German building traditions as well.  The High Victorian Gothic style did not fully emerge in the United States until after the Civil War.  Since this style was most often employed for high-style public buildings or mansions, it was essentially an urban building type.  It was often used for the design of schools and libraries.  One of Pennsylvania ’s best examples of this style  is the Pennsylvania Academy of Fine Arts in Philadelphia , designed by Frank Furness in 1876.

exotica

 

 

 

The Exotic Revival style actually encompasses several different styles, all somewhat rare, but so distinctive in design that they are worthy of mention. There are two periods of popularity associated with the Exotic Revival style, an earlier mid-19th century one when the style was first introduced and a subsequent period in the early 20th century when the style was reintroduced and revived again.   Buildings from the later period especially of the Exotic Revival style are often of grand size and scale and public use, such as churches, banks, theaters and government offices.

The Egyptian Revival style is simply the addition of Egyptian inspired columns and decorative motifs to buildings that are similar to the Greek Revival or Italianate styles in form. Scholarly interest in the archaeological discoveries of ancient Egypt early in the 19th century led to the development of Egyptian-themed buildings. The style attempted to recreate the appearance of Egyptian temples, especially with the use of massive columns that resemble sheaves of sticks tied at the top and bottom. Details refer to ancient Egyptian symbols—the phoenix, the sphinx, and the vulture and sun disk. This style was most often applied to public buildings, banks, prisons, courthouses, offices, and cemetery structures. This style was often chosen for buildings representing eternity and the afterlife. The Egyptian Revival Style flourished yet again for public buildings (especially movie theaters) from 1920 to 1930, often utilizing poured concrete as a building material. The 1835 Philadelphia County Prison (demolished in 1968) was one of the first Egyptian Revival buildings in the U.S., of imposing stone design by architect Thomas Ulrich Walter. Most surviving examples of the Egyptian Revival style are theaters, cemetery mausoleums and entry buildings, and banks.  The entrance gate to the Pottsville Cemetery with its massive columns and use of symbolic funereal decorative details is an excellent example of the Egyptian Revival style.

Another variation of the Exotic Revival is the Moorish or Oriental Revival style. This style, evocative of the Middle East or Far East, is notable for its ogee or pointed arch which appears at windows, and porches. Trim is delicate and ornate, sometimes with a lacey pattern. Some Moorish or Oriental Revival buildings have recessed porches or Turkish onion domes. The style was inspired in the late 18th and early 19th century by the increasing trade and contact with the Far East. The stylized and traditional architecture of this region appeared exotic and romantic. Like the Egyptian Revival, the Oriental Revival became popular again in the 1920s and 1930s.  While employing different decorative details and massing, the YMCA Building and Zembo Mosque in Harrisburg  are both examples of the Moorish Revival style. Chuches reflecting the Eastern European cultural tradion often are designed with gilded Moorish style onion domes. While that is a distinctive Moorish Revival style feature, it may be the only element of that style present in the overall design.

The Swiss Chalet Revival Style is another variation of the Exotic Revival style. Examples of this style appeared in the pattern books of Andrew Jackson Downing, which promoted other Romantic styles. Buildings of this style emulate the appearance of Swiss chalets, with a protruding front facing gable. A distinctive element is the second floor porch or balcony with flat cut out balustrade and trim. Sometimes stickwork or half timbering appears on the wall surfaces as well. The style also has a low-pitched roof with wide overhanging eaves supported by with brackets. This style was considered appropriate for rustic or mountainous settings, but it appears, sometimes in a more vernacular form, in varied settings throughout the state.  Few examples of the Swiss Chalet Revival variation of the Exotic style have been identified in Pennsylvania.

All three variations of the Exotic Revival style are relatively rare in Pennsylvania, but are easily identifiable due to their distinctive details.

second

The Second Empire style, also called the French Second Empire style or Mansard style, was an immensely popular style throughout the United States in the 1860s and 1870s. It was used extensively in the northeastern and midwestern parts of the country. The Second Empire style had its beginnings in France, where it was the chosen style during the reign of Napoleon III (1852-70), France’s Second Empire, hence its name. Well-attended exhibitions in Paris in 1855 and 1867 helped to spread Second Empire style to England and then the United States. The Second Empire style actually harkens back to an earlier time, the 17th century designs of French architect Francois Mansart, for whom the mansard roof is named.  The mansard roof is the key identifying feature of this style and was considered both a fashionable and functional element since it created a fully usable attic space.

In its time, the Second Empire style was viewed as a contemporary “modern” style, rather than revival style, since it was popular in France and the United States simultaneously and its combined design elements did represent a new building form. The style was first seen in America in the 1850s and flourished after the Civil War. It was so commonly employed in that era that it was sometimes referred to as the “General Grant style.”

Perhaps the best-known example of this style in Pennsylvania is the Philadelphia City Hall, built in 1871-1881. While it is distinguished by its crested mansard roof, City Hall has opulent Second Empire details throughout, including dormers with decorative hoods and elaborate columned window surrounds. Examples of the Second Empire style can be found in almost every Pennsylvania town, usually in the form of single residences, duplexes or rowhouses. Second Empire mansions or public buildings are often elaborately detailed, but many other buildings of this style have only the curving lines of the shingled mansard roof to mark them. Other commonly seen details are a bracketed cornice beneath the mansard roof, round arched windows, decorative dormer windows, an iron crest at the roofline, and columned porches or porticoes.

2.  Flat roofs
3.  Masonry wall surfaces
4.  Three part windows or projecting bay windows
5.  Decorative cornices
6.  Steel and beam construction

Commercial Style

The Commercial style reflects advances in construction technology that permitted the creation of very tall buildings, the first skyscrapers in the urban landscape.  This style is sometimes referred to as the Chicago style, after the city where steel-framed, relatively unadorned, utilitarian, tall commercial buildings first appeared in great numbers in the 1890s.  Advances in commercial architectural design in Philadelphia and New York City laid the groundwork for the full development of the Commercial style in Chicago.  William Le Baron Jenney was the first architect to employ the steel frame construction in his design for the Home Insurance building completed in Chicago in 1885.   Other prominent architects who worked in the development of this new building technology included the firms of Adler and Sullivan (Sullivan’s  embellishment of this style became its own distinctive architectural style, the Sullivanesque), Burnham and Root, and Holabird and Roche.  While the style thrived in Chicago at the turn of the 20th century, examples of the Commercial style can be found in many other cities.

Prior to the development of steel frame technology, building height had been limited by the need for massive masonry support walls.  The strength of the steel skeleton allowed for much taller buildings without the bulk of heavy masonry walls.  The invention of the elevator also facilitated the design of tall buildings by making upper floors more easily accessible.  Commercial style buildings reflecting this first wave of skyscraper construction are usually between six and twenty floors in height.  The distinguishing characteristics of this style are a steel skeleton construction, expressed externally as a grid of intersecting piers and cross spandrels, a flat roof with modest cornice, and large bands of windows.  Windows often featured a projecting bay which extended from the ground floor to the top of building.  Another common window type used for Commercial style buildings was the “Chicago window,” comprised of a large fixed central pane, flanked by two narrow casements for ventilation.  The ground floor of Commercial style buildings usually contained large display windows for storefronts.  Some examples of this style employ decorative elements of other popular styles of the era, such as Romanesque or Gothic Revival ornament.  Sullivan’s uniquely curvilinear Art Nouveau inspired ornamental panels led to its distinction as a separate architectural style. Some buildings of Commercial style are very simple in design with no notable ornamentation or reference to past architectural styles.  These bare bones commercial buildings were the precursors of even taller and more simplistic modern skyscraper design.

While the purest description of Commercial style buildings best fits early skyscrapers, many much shorter buildings are sometimes described as Commercial style.  These one to four story brick buildings date from the same era, were designed for commercial use, have large pane windows on the ground floor  and flat roofs, often with decorative parapets.  Early car dealerships and repair shops often take this form with large windows or garage door bays on the ground floor.  This subtype of the style is a more vernacular version that is more prevalent in Pennsylvania than the true high style Commercial style skyscrapers.

PA Architecture Barns and Outbuildings, 1700 – 1930

In a state like Pennsylvania where agriculture has played an enormous role from its founding to the present, barns and other agricultural outbuildings are an important part of the rural landscape. Some of these building types are unique to the region because of traditional ethnic modes of construction or specific agricultural activities, and others are universal and may be found across the country. Outbuildings of all types were developed to meet a wide variety of needs. Oftentimes, farmsteads are made up of buildings from many periods, both historic and modern. This is especially true for working farms which have erected new buildings to better adapt to contemporary farming practices. Farmhouses may take many forms or styles and are usually the nucleus of agricultural complexes. Some reflect a traditional vernacular character like the notable PA German Double Door Farmhouse and others may be high style or low style versions of popular architectural styles. Farmhouses may also be of very simple and utilitarian design, taking common housing forms such as the basic center hall I house, gabled ell house, cross gabled house or even modern ranch house. One important feature of many 18th and 19th century PA Dutch farmhouses is the summer kitchen. These small one room buildings are usually located just behind the main house. As the name implies, they served as a kitchen during the hot summer months, allowing the living quarters to remain cooler. The summer kitchen’s large fireplace could be used for cooking and laundry and other tasks.

Many farm complexes include a tenant house, which is usually a smaller, less detailed and more vernacular dwelling owned or leased by farm workers. Sometimes the tenant house is the older house of the farm, relegated to such use when a newer and fancier main house was built. Sometimes such houses were originally constructed for grown children or others as the family expanded. The “dawdi house” is a term for a home built for family elders, close to the main house, in the PA German tradition. This practice can still be seen on the farms of the Amish.

Likewise, some early dwellings were converted to outbuilding use when a finer or more permanent house was built. There are many examples of small stone or log buildings that may have begun as houses but later became springhouses, sheds or small barns. Other outbuildings were constructed to serve only one purpose, depending upon the type of crops raised and food processing needs on the farm. These outbuildings are sometimes easy to identify since they are specifically designed for just one use, like tobacco drying barns, poultry houses, root cellars, smoke houses and milk houses. Their form is much dictated by their use.

Barns play an important part in the rural landscape and Pennsylvania has many fine examples of many types. One of the earliest types of barns are log crib barns constructed of wooden logs an open interior floor plan and gable roof. One of the most distinctive types of barn in our state is the Pennsylvania Barn, a stone foundation bank barn with a projecting forebay or overhang. Prototypes for this barn can be found in Germany and Switzerland , showing its transplantation from Europe. This type of barn is also called a Switzer barn for that reason. English barns tend to be tall and narrow one story buildings that are not constructed into a bank. However, there are also banked English barns as well. Unique barns with decorative open brickwork patterns can be found especially in the southern portion of the state. Decorative elements associated with architectural styles are also applied to barns in the form of cupolas, pointed arched windows and wooden trim. The Star Barn located in Dauphin County is a recognizable landmark of Victorianized agricultural outbuildings, all featuring a distinctive louvered star pattern in the gable roof end and ornamental cupolas. Round, octagonal or polygonal barns apper with some regularity in the state, but are relatively rare. Thus, barns may be strictly utilitiarian structures or show the influence of various styles and vernacular traditions. With so many barns lost to neglect or demolition or altered for new uses, it is increasingly difficult to know for certain what types of barns were common in specific regions or constructed throughout the state.

PA Architecture Late 19th & Early 20th Century Revival Period 1880 – 1940

The Late 19th Century and Early 20th Century Revival period is sometimes described as the Eclectic Movement in American architecture. The building designs of this era were intended to be more exact versions of earlier architectural styles and traditions. In the preceding architectural periods, elements of various European inspired styles were combined and arranged to create new styles like the Gothic Revival, Italianate, or Second Empire styles. In the Late 19th Century Eclectic or Revival Period, there was a desire to create buildings that were more closely modeled after the original forms that inspired them. Most significantly, for the first time the old buildings of early America were included as the inspiration for architectural style. Interest in American history and a sense of pride in our heritage was spurred by the country’s one hundredth birthday celebrated at the Philadelphia Centennial of 1876. This focus on American tradition was continued at the Chicago Columbian Exposition of 1893.

The two most prevalent styles of this period were the Colonial Revival and the Classical Revival which were inspired by early American buildings of Georgian, Federal, or Greek or Roman Revival style.  Of course those earlier styles had been designed to incorporate stylistic elements of ancient Greece and Rome, so many of same architectural details are common to all. The larger size and scale, and arrangement of details set the buildings of the later Colonial Revival and Classical Revival apart. The Spanish Revival style and to some extent the Tudor Revival style, also looked back to the buildings of America’s colonial period. The Collegiate Gothic style was developed from the earlier Gothic Revival style and the original Gothic style buildings of Europe. The Beaux Arts style and the Italian Renaissance Revival style were all based on historic European design. This period of architecture was the last to focus on the recreation of past forms; in all the architectural periods to come, the desire to make a new architectural statement took precedence.

PA Architecture Late 19th Century & Early 20th Century Movement 1890 – 1930

The late 19th and early 20th century was a period of transition architecturally, marking the entrance into a new era of building. This was the beginning of forward looking architectural design with styles not based on previous building forms. Changes in construction techniques, especially the development of sky scraper technology, and a desire to create houses that fit visually into the natural environment influenced the developing styles of this era. The first style to emerge from this architectural movement was the Sullivanesque style. Named for its creator Louis Sullivan, a prominent American architect, the Sullivanesque style was developed as a design for sky scrapers. Sullivan divided the sky scraper into three parts, an entry level, midsection, and highly ornamented top cornice. This style shows the influence of the Art Noveau movement in the curvilinear lines and complex patterns of the decorative elements. The Commercial style, sometimes called the Chicago style, is a more pared down design for sky scrapers based on a steel frame construction. Sometimes ornamented with elements of other styles like the Romanesque or Gothic Revival, the basic grid design of the Commercial style is still evident.

The other architectural style innovations of this period occurred in the design of residential structures. American architectural force Frank Lloyd Wright created the Prairie style, desiring to develop a new domestic form that fit naturally into the environment of the Midwestern prairie. Wright, along with other Chicago architects known as the Prairie School, designed houses with gently sloping roofs, deeply overhanging eaves, and horizontal emphasis. Vernacular versions of the Prairie style such as the American Foursquare house are far more common in Pennsylvania than pure examples of the Prairie style.

The Bungalow or Craftsman style is another residential style that developed at the turn of the 20th century and became widespread throughout the country in various vernacular forms. Bungalows were first seen in California and were inspired by the English Arts and Crafts movement stressing hand-crafted materials and harmony with nature. Known for their heavy columned front porches, front facing gables, and overhanging eaves, Bungalow style houses often have exposed rafters and other decorative wood trim as well. Pattern books and mail order catalogs enabled the Bungalow style to become very popular in the developing suburbs of the early 20th century. The styles of this period set the stage for even greater change in architectural theory and practice in the years to follow.
