Coping (joinery)
–
Coping or scribing is the woodworking technique of shaping the end of a moulding or frame component to neatly fit the contours of an abutting member. Joining tubular members in metalworking is also referred to as a cope, most English speaking countries outside the United States use the terms scribe and scribing. Coping is commonly used in the fitting of skirting and other mouldings in a room and it allows for clean joints between intersecting members when walls are not square to each other. The other method of fitting these mouldings that is used is the mitre joint. Coping is only used for internal corners. The main reason that scribed joints are used is that timber shrinks in width far more than it does in length, by using a scribed joint rather than an internal mitre joint the effect of shrinkage is minimised. Also it is possible to arrange the scribed joints pointing away from the most common viewpoint, Coping is also commonly used in cabinet making for mouldings and frame components. The rails in frame and panel construction are commonly cope cut to fit the profile of the stiles, the technique is also common in the construction of doors and windows. Scribe joinery is also used in the building of log homes. The shape of the log underneath is scribed into the bottom of a log to be placed on top and this provides a tight seal between the two adjacent logs. It is also used in the building of boats since there is rarely a straight edge. Traditionally, coping would be performed using a coping saw, there are also mechanical means of producing coped joints, including matching rail and stile cutters for the router as used in frame and panel construction.

Lancaster Canal
–
The Lancaster Canal is a canal in North West England, originally planned to run from Westhoughton in Lancashire to Kendal in south Cumbria. The section around the crossing of the River Ribble was never completed, the southern part, from Johnsons Hillock to Wigan Top Lock, remains navigable as part of the Leeds and Liverpool Canal. The planned continuation to Westhoughton was never built, the line of the canal was first surveyed by Robert Whitworth in 1772. In 1791, John Longbotham, Robert Dickinson and Richard Beck resurveyed the proposed line, in 1792 the promoters sought an Act of Parliament urgently, as proposals by the Leeds and Liverpool Canal to alter their route would have affected the profitability of the southern section. John Rennie was appointed as engineer in July 1792, with William Crossley the elder as his assistant, a second Act of Parliament was obtained in May 1793 to authorise the construction of the Glasson branch, so that the canal had a connection to the sea. By 1797 the aqueduct was open, carrying the canal 62 feet above the river, in 1813, work began on the canal north from Tewitfield, which was completed to Kendal in 1819. Construction on the 2. 5-mile Glasson Dock branch began in 1819, with the coming of the railways, the proprietors sought to lease the canal to a railway company in 1860. The canal company then received £12,665.87 per year for the lease of the end of the canal. In 1955, an Act of Parliament authorised the closure of the canal, along with several others, the Inland Waterways Association organised several protest meetings, and the one held in Lancaster led to the formation of the Lancaster Canal Boat Club. One immediate effect was that it was drained of water north from Stainton because of leakage, although it was officially closed, pleasure boats continued to use the section below Tewitfield. Above the locks, a 100-yard section at Burton was drained because of problems with leakage, the route of the canal south from Kendal is still readily apparent, with most of the bridges remaining in place. Although severed by the construction, it was not drained because the channel was used to supply water to a pipeline which ran from the canal near Garstang to a chemical works near Fleetwood. As a result, this section can still be used by small boats, the isolated northern part of the canal was finally connected to the rest of the English canal network in 2002 by the opening of the Ribble Link. Most of the runs through open countryside except where it runs through the City of Lancaster. Most of the formerly occupied by the canal basin is now the University of Central Lancashire. By 1799, the canal was complete between Bark Hill near Wigan and Johnsons Hillock near Chorley, the double-track Lancaster Canal Tramroad was opened in 1803 with three steam-worked inclined planes and a low trestle bridge across the Ribble. The canal was extended north from Johnsons Hillock to Walton Summit through a tunnel at Whittle Hills and this temporary solution become permanent, and the aqueduct was never built. Although this section was the busiest on the canal, income was insufficient to pay for construction of the planned aqueduct, in 1792 the Lancaster Canal Navigation Company obtained an act to link Kendal with Westhoughton

Wall
–
A wall is a structure that defines an area, carries a load, or provides shelter or security. an earthen wall or rampart set with palisades, a row or line of stakes, a wall, a rampart, fortification. While the Latin word murus means a stone wall. English uses the word to mean an external wall and the internal sides of a room. Many languages distinguish between the two, in German, some of this distinction can be seen between Wand and Mauer, in Spanish between pared and muro. The word wall originally referred to defensive walls and ramparts, building walls purposes are to support roofs, floors and ceilings, enclose a space as part of the building envelope, along with a roof to give buildings form, and to provide shelter and security. In addition, the wall may house various types of such as electrical wiring or plumbing. Wall construction falls into two categories, framed walls or mass-walls. In framed walls the load is transferred to the foundation through posts, framed walls most often have three or more separate components, the structural elements, insulation, and finish elements or surfaces. There are three basic methods walls control water intrusion, moisture storage, drained cladding, or face-sealed cladding, moisture storage is typical of stone and brick mass-wall buildings where moisture is absorbed and released by the walls of the structure itself. Sometimes ventilation is provided in addition to the plane such as in rainscreen construction. Face-sealed also called barrier wall or perfect barrier cladding relies on maintaining a leak-free surface of the cladding, examples of face sealed cladding are the early exterior insulation finishing systems, structural glazing, metal clad panels, and corrugated metal. In architecture and civil engineering, curtain wall refers to a facade that is not load-bearing but provides decoration, finish, front, face. Mullion walls are a system that carries the load of the floor slab on prefabricated panels around the perimeter. A partition wall is a wall that separates rooms, or divides a room, partition walls are usually not load-bearing. Partition walls are constructed of materials, including steel panels, bricks, blocks of clay, terra-cotta, concrete. Some partition walls are made of sheet glass, glass partition walls are a series of individual toughened glass panels mounted in wood or metal framing. They may be suspended from or slide along a robust aluminium ceiling track, the system does not require the use of a floor guide, which allows easy operation and an uninterrupted threshold. A timber partition consists of a framework, supported on the floor or by side walls

Tile
–
A tile is a manufactured piece of hard-wearing material such as ceramic, stone, metal, or even glass, generally used for covering roofs, floors, walls, showers, or other objects such as tabletops. Alternatively, tile can sometimes refer to units made from lightweight materials such as perlite, wood. In another sense, a tile is a tile or similar object. The word is derived from the French word tuile, which is, in turn, from the Latin word tegula, Tiles are often used to form wall and floor coverings, and can range from simple square tiles to complex mosaics. Tiling stone is marble, onyx, granite or slate. Thinner tiles can be used on walls than on floors, which require more durable surfaces that will resist impacts, the earliest evidence of glazed brick is the discovery of glazed bricks in the Elamite Temple at Chogha Zanbil, dated to the 13th century BC. Glazed and colored bricks were used to make low reliefs in Ancient Mesopotamia, most famously the Ishtar Gate of Babylon, now reconstructed in Berlin. Mesopotamian craftsmen were imported for the palaces of the Persian Empire such as Persepolis, tiling was used in the second century by the Sinhalese kings of ancient Sri Lanka, using smoothed and polished stone laid on floors and in swimming pools. Historians consider the techniques and tools for tiling as well advanced, evidenced by the fine workmanship, tiling from this period can be seen Ruwanwelisaya and Kuttam Pokuna in the city of Anuradhapura. The Achaemenid Empire decorated buildings with glazed tiles, including Darius the Greats palace at Susa. The succeeding Sassanid Empire used tiles patterned with geometric designs, flowers, plants, birds and human beings, early Islamic mosaics in Iran consist mainly of geometric decorations in mosques and mausoleums, made of glazed brick. Typical turquoise tiling becomes popular in 10th-11th century and is used mostly for Kufic inscriptions on mosque walls, seyyed Mosque in Isfahan, Dome of Maraqeh and the Jame Mosque of Gonabad are among the finest examples. The dome of Jame Atiq Mosque of Qazvin is also dated to this period, the golden age of Persian tilework began during the reign the Timurid Empire. In the moraq technique, single-color tiles were cut into small geometric pieces, after hardening, these panels were assembled on the walls of buildings. But the mosaic was not limited to flat areas, Tiles were used to cover both the interior and exterior surfaces of domes. Prominent Timurid examples of this include the Jame Mosque of Yazd, Goharshad Mosque, the Madrassa of Khan in Shiraz. Other important tile techniques of time include girih tiles, with their characteristic white girih. Mihrabs, being the points of mosques, were usually the places where most sophisticated tilework was placed

Slate
–
Slate is a fine-grained, foliated, homogeneous metamorphic rock derived from an original shale-type sedimentary rock composed of clay or volcanic ash through low-grade regional metamorphism. It is the finest grained foliated metamorphic rock, foliation may not correspond to the original sedimentary layering, but instead is in planes perpendicular to the direction of metamorphic compression. The foliation in slate is called slaty cleavage and it is caused by strong compression causing fine grained clay flakes to regrow in planes perpendicular to the compression. Slate is frequently grey in color, especially when seen, en masse, Slate is not to be confused with shale, from which it may be formed, or schist. The word slate is used for certain types of object made from slate rock. It may mean a single roofing tile made of slate, or a writing slate and this was traditionally a small smooth piece of the rock, often framed in wood, used with chalk as a notepad or noticeboard, and especially for recording charges in pubs and inns. The phrases clean slate and blank slate come from this usage, before the mid-19th century, the terms slate, shale and schist were not sharply distinguished. In the context of underground mining in the United States. For example, roof slate referred to shale above a coal seam, occasionally, as in the purple slates of North Wales, ferrous reduction spheres form around iron nuclei, leaving a light green spotted texture. These spheres are sometimes deformed by a subsequent applied stress field to ovoids, Slate can be made into roofing slates, a type of roof shingle, or more specifically a type of roof tile, which are installed by a slater. Slate has two lines of breakability – cleavage and grain – which make it possible to split the stone into thin sheets, when broken, slate retains a natural appearance while remaining relatively flat and easy to stack. Slate is particularly suitable as a material as it has an extremely low water absorption index of less than 0. 4%. In fact, this natural slate, which requires only minimal processing, has the lowest embodied energy of all roofing materials, natural slate is used by building professionals as a result of its beauty and durability. Slate is incredibly durable and can last several hundred years, often little or no maintenance. Its low water makes it very resistant to frost damage and breakage due to freezing. Natural slate is also fire resistant and energy efficient, Slate roof tiles are usually fixed either with nails, or with hooks as is common with Spanish slate. In the UK, fixing is typically with double nails onto timber battens or nailed directly onto timber sarking boards, nails were traditionally of copper, although there are modern alloy and stainless steel alternatives. Both these methods, if used properly, provide a long-lasting weathertight roof with a lifespan of around 80–100 years, Slate roofs are still used today

Thatching
–
Thatching is the craft of building a roof with dry vegetation such as straw, water reed, sedge, rushes, heather, or Palm fronds, layering the vegetation so as to shed water away from the inner roof. Since the bulk of the vegetation stays dry, and is densely packed - trapping air - thatching also functions as a quite significant insulation material and it is a very old roofing method and has been used in both tropical and temperate climates. Thatch is still employed by builders in developing countries, usually with low-cost, in some equatorial countries, thatch is the prevalent local material for roofs, and often walls. There are diverse building techniques from the ancient Hawaiian hale shelter made from the local ti leaves, Palm leaves are also often used. For example, in Na Bure, Fiji, thatchers combine fan palm leave roofs with layered reed walls, feathered palm leaf roofs are used in Dominica. Alang-alang thatched roofs are used in Hawaii and Bali, in Southeast Asia, mangrove nipa palm leaves are used as thatched roof material known as attap dwelling. In Bali, Indonesia, the fibres of Arenga pinnata called ijuk is also used as thatched roof materials, usually used in Balinese temple roof. Sugar cane leaf roofs are used in Kikuyu tribal homes in Kenya, many indigenous people, such as the Maya, the Inca, and the Triple Alliance, lived in thatched buildings. Evidence of the complex buildings with fiber-based roofing material was not rediscovered until the early 2000s. French and British settlers built temporary thatched dwellings with local vegetation as soon as arrived in New France and New England. In most of England, thatch remained the only roofing material available to the bulk of the population in the countryside, in towns and villages. Commercial production of Welsh slate began in 1820, and the mobility provided by canals, gradually, thatch became a mark of poverty, and the number of thatched properties gradually declined, as did the number of professional thatchers. Thatch has become more popular in the UK over the past 30 years. Although thatch is popular in Germany, The Netherlands, Denmark, parts of France, Sicily, Belgium and Ireland, good quality straw thatch can last for more than 50 years when applied by a skilled thatcher. Traditionally, a new layer of straw was simply applied over the surface. The straw is bundled into yelms before it is taken up to the roof and then is attached using staples, known as spars, almost all of these roofs are thatched with wheat, rye, or a maslin mixture of both. Medieval wheat grew to almost 6 feet tall in very poor soils and produced durable straw for the roof, technological change in the farming industry significantly affected the popularity of thatching. The availability of good quality thatching straw declined in England after the introduction of the harvester in the late 1930s and 1940s

Copper in architecture
–
Copper has earned a respected place in the related fields of architecture, building construction, and interior design. The history of copper in architecture can be linked to its durability, corrosion resistance, prestigious appearance, for centuries, craftsmen and designers utilized these attributes to build aesthetically pleasing and long-lasting building systems. For the past quarter century, copper has been designed into a wider range of buildings, incorporating new styles, varieties of colors. Copper clad walls are a design element in both indoor and outdoor environments. Some of the worlds most distinguished modern architects have relied on copper, architect Frank O. Gehry’s enormous copper fish sculpture atop the Vila Olimpica in Barcelona is an example of the artistic use of copper. Copper’s most famous trait is its display from a metallic colour to iridescent brown to near black. Architects describe the array of browns as russet, chocolate, plum, mahogany, the metal’s distinctive green patina has long been coveted by architects and designers. This article describes practical and aesthetic benefits of copper in architecture as well as its use in applications, interior design elements. Copper has played a role in architecture for thousands of years, for example, in ancient Egypt, massive doors to the temple of Amen-Re at Karnak were clad with copper. In the 3rd Century B. C. copper roof shingles were installed atop of the Lowa Maha Paya Temple in Sri Lanka, and the Romans used copper as roof covering for the Pantheon in 27 B. C. Centuries later, copper and its alloys were integral in medieval architecture, the doors of the Church of the Nativity at Bethlehem are covered with plates of bronze, cut out in patterns. Those of Hagia Sophia at Constantinople, of the 8th and 9th century, are wrought in bronze, bronze doors on the Aachen Cathedral in Germany date back to about 800 A. D. Bronze baptistery doors at the Cathedral of Florence were completed in 1423 A. D. by Ghiberti, the copper roof of Hildesheim Cathedral, installed in 1280 A. D. survives to this day. And the roof at Kronborg, one of northern Europes most important Renaissance castles that was immortalized as Elsinore Castle in Shakespeare’s Hamlet, was installed in 1585 A. D, the copper on the tower was renovated in 2009. For years, copper was reserved mainly for public institutions, such as churches, government buildings, Copper roofs are often one of the most architecturally distinguishable features of these structures. In the 21st century, the use of copper continues to evolve in the indoor environment and its recently proven antimicrobial properties reduce pathogenic bacterial loads on such products as handrails, bedrails, bathroom fixtures, counter tops, etc. These antimicrobial copper-based products are now being incorporated into public facilities as well as in residential buildings because of the health benefits. As an architectural metal, copper provides excellent corrosion resistance, Copper surfaces form tough oxide-sulfate patina coatings that protect underlying copper surfaces and resist corrosion for a very long time

Romanesque architecture
–
Romanesque Architecture is an architectural style of medieval Europe characterized by semi-circular arches. There is no consensus for the date of the Romanesque style, with proposals ranging from the 6th to the late 10th century. It developed in the 12th century into the Gothic style, marked by pointed arches, examples of Romanesque architecture can be found across the continent, making it the first pan-European architectural style since Imperial Roman Architecture. The Romanesque style in England is traditionally referred to as Norman architecture, each building has clearly defined forms, frequently of very regular, symmetrical plan, the overall appearance is one of simplicity when compared with the Gothic buildings that were to follow. The style can be identified right across Europe, despite regional characteristics, Many castles were built during this period, but they are greatly outnumbered by churches. The most significant are the great churches, many of which are still standing, more or less complete. The largest groups of Romanesque survivors are in areas that were less prosperous in subsequent periods, including parts of southern France, northern Spain and rural Italy. According to the Oxford English Dictionary, the word Romanesque means descended from Roman and was first used in English to designate what are now called Romance languages, Romance language is not degenerated Latin language. Latin language is degenerated Romance language, Romanesque architecture is not debased Roman architecture. Roman architecture is debased Romanesque architecture, the first use in a published work is in William Gunns An Inquiry into the Origin and Influence of Gothic Architecture. The term is now used for the more restricted period from the late 10th to 12th centuries, Many castles exist, the foundations of which date from the Romanesque period. Most have been altered, and many are in ruins. By far the greatest number of surviving Romanesque buildings are churches, the scope of Romanesque architecture Romanesque architecture was the first distinctive style to spread across Europe since the Roman Empire. In the more northern countries Roman building styles and techniques had never been adopted except for official buildings, although the round arch continued in use, the engineering skills required to vault large spaces and build large domes were lost. There was a loss of continuity, particularly apparent in the decline of the formal vocabulary of the Classical Orders. In Rome several great Constantinian basilicas continued in use as an inspiration to later builders, the largest building is the church, the plan of which is distinctly Germanic, having an apse at both ends, an arrangement not generally seen elsewhere. Another feature of the church is its regular proportion, the plan of the crossing tower providing a module for the rest of the plan. These features can both be seen at the Proto-Romanesque St. Michaels Church, Hildesheim, 1001–1030, the style, sometimes called First Romanesque or Lombard Romanesque, is characterised by thick walls, lack of sculpture and the presence of rhythmic ornamental arches known as a Lombard band

Astragal
–
An astragal is a moulding profile composed of a half-round surface surrounded by two flat planes. An astragal is sometimes referred to as a miniature torus and it can be an architectural element used at the top or base of a column, but is also employed as a framing device on furniture and woodwork. The word astragal comes from the Greek and Latin for vertebra, an astragal is commonly used to seal between a pair of doors. The astragal closes the gap created by bevels on one or both mating doors, and helps deaden sound. The vertical member attaches to a stile on one of a pair of sliding or swinging doors. Exterior astragals are kerfed for weatherstripping, an astragal may also be known as a “meeting stile seal”. It is sometimes confused with the wooden trim that divides the panes of a window or door

English Gothic architecture
–
English Gothic is an architectural style that flourished in England from about 1180 until about 1520. As with the Gothic architecture of other parts of Europe, English Gothic is defined by its arches, vaulted roofs, buttresses, large windows. The earliest large-scale applications of Gothic architecture in England are at Canterbury Cathedral, many features of Gothic architecture had evolved naturally from Romanesque architecture. This evolution can be seen most particularly at the Norman Durham Cathedral, English Gothic was to develop along lines that sometimes paralleled and sometimes diverged from those of continental Europe. Historians traditionally divide English Gothic into a number of different periods, Gothic architecture continued to flourish in England for a hundred years after the precepts of Renaissance architecture were formalised in Florence in the early 15th century. Many of the largest and finest works of English architecture, notably the medieval cathedrals of England are largely built in the Gothic style, so also are castles, palaces, great houses, universities, and many smaller unpretentious secular buildings, including almshouses and trade halls. Another important group of Gothic buildings in England are the parish churches, historians sometimes refer to the styles as periods, e. g. Perpendicular period in much the same way as an historical era may be referred to as the Tudor period. The various styles are seen at their most fully developed in the cathedrals, abbey churches, according to the originator of the term in 1817, Thomas Rickman, the period ran from 1189 to 1307, Rickman based his defining dates on the reigns of certain English monarchs. In the late 12th century, the Early English Gothic style superseded the Romanesque or Norman style, during the late 13th century, it developed into the Decorated Gothic style, which lasted until the mid-14th century. With all of early architectural styles, there is a gradual overlap between the periods. As fashions changed, new elements were used alongside older ones, especially in large buildings such as churches and cathedrals. It is customary, therefore, to recognise a transitional phase between the Romanesque and Early English periods from the middle of the 12th century, although usually known as Early English, this new Gothic style had originated in the area around Paris before spreading to England. There it was first known as the French style and it was first used in the choir or quire of the abbey church of St Denis, dedicated in June 1144. Even before that, some features had been included in Durham Cathedral, showing a combination of Romanesque, by 1175, with the completion of the Choir at Canterbury Cathedral by William of Sens, the style was firmly established in England. The most significant and characteristic development of the Early English period was the pointed arch known as the lancet, pointed arches were used almost universally, not only in arches of wide span such as those of the nave arcade, but also for doorways and lancet windows. It also allows for greater variation in proportions, whereas the strength of round arches depends on semicircular form. The barrel vaults and groin vaults characteristic of Romanesque building were replaced by rib vaults, the arched windows are usually narrow by comparison to their height and are without tracery. For this reason Early English Gothic is sometimes known as the Lancet style, although arches of equilateral proportion are most often employed, lancet arches of very acute proportions are frequently found and are highly characteristic of the style
