A functionally classified barn is a barn whose style is best classified by its function. Barns that do not fall into one of the broader categories of barn styles, such as English barns or crib barns, can best be classified by some combination of two factors, region and usage. Examples of barns classified by function occur worldwide and include apple barn, rice barn, potato barn, hop barn, tobacco barn, cattle barn (pole barn), and the tractor barn. In addition, some barns incorporate their region into their style classification. Examples include the Wisconsin dairy barn, Pennsylvania bank barn, or the Midwest feeder barn. [1]

Barn Agricultural building used for storage and as a covered workplace

A barn is an agricultural building usually on farms and used for various purposes. In the North American area, a barn refers to structures that house livestock, including cattle and horses, as well as equipment and fodder, and often grain. As a result, the term barn is often qualified e.g. tobacco barn, dairy barn, sheep barn, potato barn. In the British Isles, the term barn is restricted mainly to storage structures for unthreshed cereals and fodder, the terms byre or shippon being applied to cow shelters, whereas horses are kept in buildings known as stables. On the Continent, however, barns were often part of integrated structures known as byre-dwellings. In addition, barns may be used for equipment storage, as a covered workplace, and for activities such as threshing.

Rice barn

A rice barn is a type of barn used worldwide for the storage and drying of harvested rice. The designs, usually specialized to its function, and it may vary between countries or between provinces. Rice barns in Asia appear quite different from rice barns found in other parts of the rice cultivating world. In the United States rice barns were once common throughout the state of South Carolina.

Wisconsin dairy barn

A Wisconsin dairy barn is a style of barn developed presumably in the U.S. state of Wisconsin, but present in other U.S. states, especially further west.

Tobacco barns

Tobacco barns were once an essential ingredient in the process of air curing tobacco. In the 21st century they are fast disappearing from the American landscape in places where they were once ubiquitous. [2] U.S. States, such as Maryland, have sponsored programs which discourage the cultivation of tobacco. In 2001 Maryland's state sponsored program offered cash payments as buyouts to tobacco farmers. [2] A majority of the farmers took the buyout and hundreds of historic tobacco barns were rendered instantly obsolete. [2] As tobacco barns disappear farmer have been forced to change their methods for curing the crop. In Kentucky, instead of curing tobacco attached to laths in vented tobacco barns as they once did, farmers are increasingly curing tobacco on "scaffolds" in the fields. [3]

Maryland State of the United States of America

Maryland is a state in the Mid-Atlantic region of the United States, bordering Virginia, West Virginia, and the District of Columbia to its south and west; Pennsylvania to its north; and Delaware to its east. The state's largest city is Baltimore, and its capital is Annapolis. Among its occasional nicknames are Old Line State, the Free State, and the Chesapeake Bay State. It is named after the English queen Henrietta Maria, known in England as Queen Mary.

Tobacco agricultural product processed from the leaves of plants in the genus Nicotiana

Tobacco is a product prepared from the leaves of the tobacco plant by curing them. The plant is part of the genus Nicotiana and of the Solanaceae (nightshade) family. While more than 70 species of tobacco are known, the chief commercial crop is N. tabacum. The more potent variant N. rustica is also used around the world.

Lath

A lath or slat is a thin, narrow strip of straight-grained wood used under roof shingles or tiles, on lath and plaster walls and ceilings to hold plaster, and in lattice and trellis work.

Design

Design elements which were common to American tobacco barns include: gabled roofs, frame construction, and some system of ventilation. The venting can appear in different incarnations but commonly hinges would be attached to some of the cladding boards, so that they could be opened. [4] Often the venting system would be more elaborate, including a roof ventilation system. The interior would have its framing set up in bents about ten to fifteen feet apart so that laths with tobacco attached to them could be hung for drying. There is no one design that typifies tobacco barns but they share some common elements not seen in other barns. [4] However, tobacco barns do cross over into other barn styles of their day. Some common types of barn designs integrated into tobacco barns include, English barns and bank barns. [4]

Gable Generally triangular portion of a wall between the edges of intersecting roof pitches

A gable is the generally triangular portion of a wall between the edges of intersecting roof pitches. The shape of the gable and how it is detailed depends on the structural system used, which reflects climate, material availability, and aesthetic concerns. A gable wall or gable end more commonly refers to the entire wall, including the gable and the wall below it.

Ventilation (architecture) intentional introduction of outside air into a space

Ventilation is the intentional introduction of outdoor air into a space and is mainly used to control indoor air quality by diluting and displacing indoor pollutants; it can also be used for purposes of thermal comfort or dehumidification.

Cladding (construction) overlapping layer; building element

Cladding is the application of one material over another to provide a skin or layer. In construction, cladding is used to provide a degree of thermal insulation and weather resistance, and to improve the appearance of buildings. Cladding can be made of any of a wide range of materials including wood, metal, brick, vinyl, and composite materials that can include aluminium, wood, blends of cement and recycled polystyrene, wheat/rice straw fibres. Rainscreen cladding is a form of weather cladding designed to protect against the elements, but also offers thermal insulation. The cladding does not itself need to be waterproof, merely a control element: it may serve only to direct water or wind safely away in order to control run-off and prevent its infiltration into the building structure. Cladding may also be a control element for noise, either entering or escaping. Cladding can become a fire risk by design or material.

Hop barns

Also known as hop houses or hop kilns, hop barns were very common in areas of the United States where hops were grown. Hop barns were so common it was said that "every other farm" had one. [5] In New York state's "hop belt" numerous hop barns were constructed between the early 19th century and the beginning of the 20th century. Ostego, Chenango, Madison, Oneida, Montgomery and Schoharie Counties were the primary areas contained within the hop belt. [5] As hops production basically dwindled down to only Washington state, in the U.S., the remaining hop houses elsewhere have begun to disappear. Defunct hop kilns are found in areas where hops production is still ongoing, in Kent, England, for instance.

Kent County of England

Kent is a county in South East England and one of the home counties. It borders Greater London to the north-west, Surrey to the west and East Sussex to the south-west. The county also shares borders with Essex along the estuary of the River Thames, and with the French department of Pas-de-Calais through the Channel Tunnel. The county town is Maidstone.

England Country in north-west Europe, part of the United Kingdom

England is a country that is part of the United Kingdom. It shares land borders with Wales to the west and Scotland to the north-northwest. The Irish Sea lies west of England and the Celtic Sea lies to the southwest. England is separated from continental Europe by the North Sea to the east and the English Channel to the south. The country covers five-eighths of the island of Great Britain, which lies in the North Atlantic, and includes over 100 smaller islands, such as the Isles of Scilly and the Isle of Wight.

Design

The design of hop houses changed significantly over time, as did the area hops were grown in. In New York, for instance, early hop barns were low with some ventilation. [5] Later hop barns evolved into taller, more narrow buildings, often topped with a cupola over the drying kiln area. Later in the history of New York hops production, with farmers focused on more efficient means of production, pyramid shaped barns were built, eventually evolving into multi-pyramid hop barns. [5]

In architecture, a cupola is a relatively small, most often dome-like, tall structure on top of a building. Often used to provide a lookout or to admit light and air, it usually crowns a larger roof or dome.

Kiln oven that generates high temperatures

A kiln is a thermally insulated chamber, a type of oven, that produces temperatures sufficient to complete some process, such as hardening, drying, or chemical changes. Kilns have been used for millennia to turn objects made from clay into pottery, tiles and bricks. Various industries use rotary kilns for pyroprocessing—to calcinate ores, to calcinate limestone to lime for cement, and to transform many other materials.

Pyramid structure whose shape is roughly that of a pyramid in the geometric sense

A pyramid is a structure whose outer surfaces are triangular and converge to a single point at the top, making the shape roughly a pyramid in the geometric sense. The base of a pyramid can be trilateral, quadrilateral, or of any polygon shape. As such, a pyramid has at least three outer triangular surfaces. The square pyramid, with a square base and four triangular outer surfaces, is a common version.

Potato barns and houses

Barns designed to store potatoes are semi-subterranean (partially below ground) to naturally moderate the indoor temperature like a giant root cellar. The potatoes in storage could not be allowed to freeze or get too warm. [6] Potatoes were not mass-produced until the end of the 19th century and so most old potato barns are 20th-century buildings with concrete walls. [7]

Root cellar structure, usually underground or partially underground, used for storage of vegetables, fruits, nuts, or other foods

A root cellar is a structure, usually underground or partially underground, used for storage of vegetables, fruits, nuts, or other foods. Its name reflects the traditional focus on root crops stored in an underground cellar, which is still often true, although a wide variety of foods can potentially be stored, for weeks to months, depending on the crop and the conditions, and the structure may not always be underground.

Buildings to store sweet potatoes are sometimes called a potato house.

Pole barns

A pole barn in North America is a barn that is essentially a roof extended over a series of poles. They are generally rectangular and do not require exterior walls. The roof is supported by the poles, which make up the perimeter of the barn. [8] Walls may be added to pole barns but are not required for structural integrity. The roof can be gabled or hooped. Pole barns are often used for hay storage or livestock shelter, and larger structures are also used for indoor horse stables and riding arenas. This type of barn is not only very common in modern agriculture but is also used for other applications where large spaces are needed, including boat and truck storage, warehouses, strip malls, retail stores, public exhibit buildings at a fairgrounds, and related uses. Residential garages are also built as pole barns because of their quick construction time and efficient use of materials.

The advantages of pole barns include their low cost and their ability to store large quantities of hay or other materials in areas easily accessible by vehicles, machines, and people. [9]

In the United Kingdom a pole barn refers to a type of Dutch barn.

Design

The design of most pole barns is simple. Poles make up the outer walls and support the roof system, usually pre-engineered wood trusses with a roof sheathing. Poles are usually spaced 8' apart, with the trusses bearing directly on the poles. Some variations in design call for truss carrying beams between the posts with trusses sitting on them. The exterior walls consist of girts attached horizontally to the post with the exterior sheathing attached to them. Exterior walls may be finished with corrugated metal, plywood sheathing, vinyl siding, or other cladding. Roof materials are generally corrugated metal but may be finished using any typical roofing product.

Depending on the function of the barn, there can be slight differences in style. For instance, a barn used for storing hay may lack any kind of lower exterior wall, whereas a pole barn used to house livestock would have some form of wall meeting the roof. [10]

History of Pole Barns

In the 1930s, post-frame construction had its start with the development of two key components: availability in rural areas of wood telephone and electricity poles, and corrugated steel sheeting. By using poles embedded in the ground, along with steel roofing and siding, the amount of framing, siding, and foundation material needed to construct a barn was drastically reduced. The columns were literally telephone poles – hence the term 'pole barn'. After World War 2, 'poles' were replaced by solid sawn posts, usually 4×6 or 6×6. The posts were chemically treated to resist decay, greatly increasing the useful life of a building. In the 1950s and 1960s, metal-plate-connected wood trusses were developed, increasing roof spans, eventually up to 100′ (30 m). In the 1970s and 1980s, solid sawn posts were supplemented by laminated 2×6 and 2×8 posts, allowing taller buildings. [11] Since the 1980s, pole barns have been adapted for a variety of uses, including residential garages, retail stores, light commercial buildings, and professional offices. [12] Corrugated metal is still very common, but other exteriors such as vinyl siding, stucco, and cement board are also used.

The National Frame Builders Association is a trade group for the post-frame construction industry.

Rice barns

Rice barns are used ubiquitously in the rice cultivating world for the storage and drying of harvested rice. They are prevalent in many Southeast Asian nations, Laos, Cambodia, Thailand and Indonesia among them. In North America rice barns were especially common in the U.S. state of South Carolina. [13]

Design

Rice barn design varies greatly from region to region and, especially, nation to nation. South Carolinian rice barns were often clad in cypress shingles. [14] In Asia a common barn design is a four pole, open-walled building; a structure that does not resemble the classical image of a barn in any way. [15]

Significance

United States

Barn design, overall, bears architectural, cultural and historical significance, as well as some anthropological and sociological significance. [13] Barn design speaks to two distinct parameters in agricultural history, one being climate and the other being occupation. [13] Different types of barns tell much about what inhabitants of the past cultivated and in what type of climate they did it in. In the United States climate allows regional barn variation to easily be divided along a north/south axis. [13] Design divided along these lines speaks to how farmers responded to the severity of the winter. In the north, where cold, harsh winters are common, buildings were more extensive and spacious, to house animals, crops and vehicles. [13] South and west, in the U.S., where the weather tends to be more mild, barn design focused on smaller more specialized structures such as tobacco barns. [13] It is regional differences in North American climate that produced the major differences in northern and southern American barns.

After climatology the biggest factor in barn design is function. All over the United States barn designs, such as those discussed above, were developed based upon the individual needs of specific crops or livestock. [13]

Truss structure that consists of two-force members only

In engineering, a truss is a structure that "consists of two-force members only, where the members are organized so that the assemblage as a whole behaves as a single object". A "two-force member" is a structural component where force is applied to only two points. Although this rigorous definition allows the members to have any shape connected in any stable configuration, trusses typically comprise five or more triangular units constructed with straight members whose ends are connected at joints referred to as nodes.

Timber framing building technique, construction method using heavy squared-off and carefully fitted and joined timbers

Timber framing and "post-and-beam" construction are traditional methods of building with heavy timbers, creating structures using squared-off and carefully fitted and joined timbers with joints secured by large wooden pegs. It is commonplace in wooden buildings from the 19th century and earlier. If the structural frame of load-bearing timber is left exposed on the exterior of the building it may be referred to as half-timbered, and in many cases the infill between timbers will be used for decorative effect. The country most known for this kind of architecture is Germany. Timber framed houses are spread all over the country except in the southeast.

Framing (construction) in construction, is the fitting together of pieces to give a structure support and shape

Framing, in construction, is the fitting together of pieces to give a structure support and shape. Framing materials are usually wood, engineered wood, or structural steel. The alternative to framed construction is generally called mass wall construction, where horizontal layers of stacked materials such as log building, masonry, rammed earth, adobe, etc. are used without framing.

Saltbox building with a long, pitched roof that slopes down to the back

A saltbox house is a traditional New England style of house with a long, pitched roof that slopes down to the back, generally a wooden frame house. A saltbox has just one story in the back and two stories in the front. The flat front and central chimney are recognizable features, but the asymmetry of the unequal sides and the long, low rear roof line are the most distinctive features of a saltbox, which takes its name from its resemblance to a wooden lidded box in which salt was once kept.

Awning secondary covering attached to the exterior wall of a building

An awning or overhang is a secondary covering attached to the exterior wall of a building. It is typically composed of canvas woven of acrylic, cotton or polyester yarn, or vinyl laminated to polyester fabric that is stretched tightly over a light structure of aluminium, iron or steel, possibly coot or transparent material. The configuration of this structure is something of a truss, space frame or planar frame. Awnings are also often constructed of aluminium understucture with aluminium sheeting. These aluminium awnings are often used when a fabric awning is not a practical application where snow load as well as wind loads may be a factor.

Purlin structural member in a roof

In architecture, structural engineering or building, a purlin is any longitudinal, horizontal, structural member in a roof except a type of framing with what is called a crown plate. In traditional timber framing there are three basic types of purlin: purlin plate, principal purlin and common purlin.

Domestic roof construction the supporting structure of a roof, necessary for its stability

Domestic roof construction is the framing and roof covering which is found on most detached houses in cold and temperate climates. Such roofs are built with mostly timber, take a number of different shapes, and are covered with a variety of materials.

Dutch barn type of barn

Dutch barn is the name given to markedly different types of barns in the United States and Canada, and in the United Kingdom. In the United States, Dutch barns represent the oldest and rarest types of barns. There are relatively few—probably fewer than 600—of these barns still intact. Common features of these barns include a core structure composed of a steep gabled roof, supported by purlin plates and anchor beam posts, the floor and stone piers below. Little of the weight is supported by the curtain wall, which could be removed without affecting the stability of the structure. Large beams of pine or oak bridge the center aisle for animals to provide room for threshing. Entry was through paired doors on the gable ends with a pent roof over them, and smaller animal doors at the corners of the same elevations. The Dutch Barn has a square profile, unlike the more rectangular English or German barns. In the United Kingdom a structure called a Dutch barn is a relatively recent agricultural development meant specifically for hay and straw storage; most examples were built from the 19th century. British Dutch barns represent a type of pole barn in common use today. Design styles range from fixed roof to adjustable roof; some Dutch barns have honeycombed brick walls, which provide ventilation and are decorative as well. Still other British Dutch barns may be found with no walls at all, much like American pole barns.

The tobacco barn, a type of functionally classified barn found in the USA, was once an essential ingredient in the process of air-curing tobacco. In the 21st century they are fast disappearing from the landscape in places where they were once ubiquitous. The barns have declined with the tobacco industry in general, and U.S. States such as Maryland actively discourage tobacco farming. When the US tobacco industry was at its height, tobacco barns were found everywhere the crop was grown. Tobacco barns were as unique as each area in which they were erected, and there is no one design that can be described as a tobacco barn.

Pole building framing

Pole framing or post-frame construction is a simplified building technique adapted from the labor-intensive traditional timber framing technique. It uses large poles or posts buried in the ground or on a foundation to provide the vertical structural support, along with girts to provide horizontal support. The method was developed and matured during the 1930s as agricultural practices changed, including the shift toward engine-powered farm equipment and the demand for cheaper, larger barns and storage areas.

Timber roof truss

A timber roof truss is a structural framework of timbers designed to bridge the space above a room and to provide support for a roof. Trusses usually occur at regular intervals, linked by longitudinal timbers such as purlins. The space between each truss is known as a bay.

Gin gang structure built to enclose a horse mill

A gin gang, wheelhouse, roundhouse or horse-engine house, is a structure built to enclose a horse engine, usually circular but sometimes square or octagonal, attached to a threshing barn. Most were built in England in the late 18th and early 19th centuries. The threshing barn held a small threshing machine which was connected to the gin gang via wooden gears, drive shafts and drive belt, and was powered by a horse which walked round and round inside the gin gang.

McCauley and Meyer Barns

The McCauley and Meyer Barns in Yosemite National Park are the last barns in the park that retain their original characteristics as structures built by homesteaders. The McCauley barn and the two Meyer barns represent different construction techniques and styles of design.

A post is a main vertical or leaning support in a structure similar to a column or pillar but the term post generally refers to a timber but may be metal or stone. A stud in wooden or metal building construction is similar but lighter duty than a post and a strut may be similar to a stud or act as a brace. In the U.K. a strut may be very similar to a post but not carry a beam. In wood construction posts normally land on a sill, but in rare types of buildings the post may continue through to the foundation called an interrupted sill or into the ground called earthfast, post in ground, or posthole construction. A post is also a fundamental element in a fence. The terms "jack" and "cripple" are used with shortened studs and rafters but not posts, except in the specialized vocabulary of shoring.

New England barn

The New England Barn was the most common style of barn built in most of the 19th century in rural New England and variants are found throughout the United States. This style barn superseded the ”three-bay barn” in several important ways. The most obvious difference is the location of the barn doors on the gable-end(s) rather than the sidewall(s). The New England and three bay barns were used similarly as multipurpose farm buildings but the New England barns are typically larger and have a basement. Culturally the New England Barn represents a shift from subsistence farming to commercial farming thus are larger and show significant changes in American building methods and technologies. Most were used as dairy barns but some housed teams of oxen which are generally called teamster barns. Sometimes these barns are simply called “gable fronted” and “gable fronted bank barns” but these terms are also used for barns other than the New England style barn such as in Maryland and Virginia which is not exactly the same style as found in New England. A similar style found in parts of the American mid-west and south is called a transverse frame barn or transverse crib barn.

American historic carpentry

American historic carpentry is the historic methods with which wooden buildings were built in what is now the United States since European settlement. A number of methods were used to form the wooden walls and the types of structural carpentry are often defined by the wall, floor, and roof construction such as log, timber framed, balloon framed, or stacked plank. Some types of historic houses are called plank houses but plank house has several meanings which are discussed below. Roofs were almost always framed with wood, sometimes with timber roof trusses. Stone and brick buildings also have some wood framing for floors, interior walls and roofs.

Tobacco Kiln, Oak Valley

Tobacco Kiln is a heritage-listed kiln at 12 Chisholm Trail, Oak Valley, City of Townsville, Queensland, Australia. It was built c. 1933 by Dick Moyes. It is also known as Flue Curing Barn. It was added to the Queensland Heritage Register on 27 September 2002.

Gothic-arch barn

A Gothic-arched roof barn or Gothic-arch barn or Gothic barn or rainbow arch is a barn whose profile is in the ogival shape of a Gothic arch. These became economically feasible when arch members could be formed by a lamination process. The distinctive roofline features a center peak as in a gable roof, but with symmetrical curved rafters instead of straight ones. The roof could extend to the ground making the roof and walls a complete arch, or be built as an arched roof on top of traditionally framed walls.
