A roundhouse is a type of house with a circular plan, usually with a conical roof. In the later part of the 20th century, modern designs of roundhouse eco-buildings were constructed with materials such as cob, cordwood or straw bale walls and reciprocal frame green roofs.
Roundhouses were the standard form of housing built in Britain and Ireland from the Bronze Age throughout the Iron Age, and in some areas well into the Sub Roman period. The people built walls made of either stone or of wooden posts joined by wattle-and-daub panels, and topped with a conical thatched roof. These ranged in size from less than 5m in diameter to over 15m. The Atlantic roundhouse, Broch, and Wheelhouse styles were used in Scotland. The remains of many Bronze Age roundhouses can still be found scattered across open heathland, such as Dartmoor, as stone 'hut circles'.
Early archeologists determined what they believed were the characteristics of such structures by the layout of the postholes, although a few timbers were found preserved in bogs. The rest has been postulated by experimental archaeology, which has tried different techniques to demonstrate the most likely form and function of the buildings. For example, experiments have shown that a conical roof with a pitch of about 45 degrees would have been the strongest and most efficient design. According to Peter J. Reynolds fire would have been lit inside for heating and cooking, there could not have been a smoke hole in the apex of the roof, for this would have caused an updraft that would have rapidly set fire to the thatch. Instead, smoke would have been allowed to accumulate harmlessly inside the roof space, and slowly leak out through the thatch. [1]
Many modern simulations of roundhouses have been built, including:

Much of the earlier supposition was confirmed or denied at a stroke by the finding of a set of Bronze Age roundhouses at the archaeological dig at Must Farm in Cambridgeshire, UK, where samples of all the materials, from posts to walls, to roof were all found, collapsed and charred, but still in situ after 3,000 years.
That Roundhouse is an early example of a modern roundhouse dwelling which was built in Pembrokeshire Coast National Park, Wales without planning permission as part of the Brithdir Mawr village which was discovered by the authorities in 1998. [4] It is constructed from a wooden frame of hand-cut Douglas Fir forest thinnings with cordwood infill, and reciprocal frame turf roof based on permaculture principles mainly from local natural resources. It was subject to a lengthy planning battle including a court injunction to force its demolition before finally receiving planning approval for 3 years in September 2008. [5]

Trulli (singular: trullo) are houses with conical roofs, and sometimes circular walls, found in parts of the southern Italian region of Apulia.
A palloza is a traditional thatched house as found in Leonese county of El Bierzo, Serra dos Ancares in Galicia, and south-west of Asturias; corresponding to Astur tribes area, one of pre Hispano-Celtic inhabitants of northwest Hispania. It is circular or oval, and about ten or twenty metres in diameter and is built to withstand severe winter weather at a typical altitude of 1,200 metres.
The main structure is stone, and is divided internally into separate areas for the family and their animals, with separate entrances. The roof is conical, made from rye straw on a wooden frame. There is no chimney, the smoke from the kitchen fire seeps out through the thatch.
As well as living space for humans and animals, a palloza has its own bread oven, workshops for wood, metal and leather work, and a loom. Only the eldest couple of an extended family had their own bedroom, which they shared with the youngest children. The rest of the family slept in the hay loft, in the roof space.
The Taganrog Round House is a residential apartment building in Taganrog, Rostov and was the first round house built in the USSR. The building is a modern round house built in 1929 and inhabited on 7 November 1932. The shared toilet was outside the house, about 20 meters from it. [6] Plumbing and sewerage were equipped in the apartments of the house only in the early 1960s. By the 80th anniversary of the round house in October 2012, major repairs were carried out, and the anniversary itself was marked by a celebration held in the courtyard by the tenants of the house. [7]
Roundhouses were a common form of architecture in some Native American Tribes. Traditional roundhouses were often used for ceremonies "and provided a large work area during inclement weather." [8] The Chaw Se' Roundhouse in California's Indian Grinding Rock State Historic Park is designated with state historical marker #1001. [9]
Modern roundhouses are being built such as the one at Dancing Rabbit Ecovillage near Rutledge, Missouri, built of cob. [10]

The African round hut is still in use.
Raun Haus roundhouses are still in use in Papua New Guinea and are very similar to the ones built in western Europe. [11]
The Igloo is a temporary roundhouse built from ice.
In archaeology, a broch is an Iron Age drystone hollow-walled structure found in Scotland. Brochs belong to the classification "complex Atlantic roundhouse" devised by Scottish archaeologists in the 1980s.
Thatching is the craft of building a roof with dry vegetation such as straw, water reed, sedge, rushes, heather, or palm branches, 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 insulation. 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 local vegetation. By contrast, in some developed countries it is the choice of some affluent people who desire a rustic look for their home, would like a more ecologically friendly roof, or who have purchased an originally thatched abode.
A barn is an agricultural building usually on farms and used for various purposes. In North America, 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, cow house, 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. In mainland Europe, 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.
Jarlshof is the best-known prehistoric archaeological site in Shetland, Scotland. It lies in Sumburgh, Mainland, Shetland and has been described as "one of the most remarkable archaeological sites ever excavated in the British Isles". It contains remains dating from 2500 BC up to the 17th century AD.
A blackhouse is a traditional type of house which used to be common in Ireland, the Hebrides, and the Scottish Highlands.
Cordwood construction is a term used for a natural building method in which short logs are piled crosswise to build a wall, using mortar or cob to permanently secure them. This technique can use local materials at minimal cost.
Navan Fort is an ancient ceremonial monument near Armagh, Northern Ireland. According to tradition it was one of the great royal sites of pre-Christian Gaelic Ireland and the capital of the Ulaidh. It is a large circular hilltop enclosure—marked by a bank and ditch—inside which is a circular mound and the remains of a ring barrow. Archeological investigations show that there were once buildings on the site, including a huge roundhouse-like structure that has been likened to a temple. In a ritual act, this timber structure was filled with stones, deliberately burnt down and then covered with earth to create the mound which stands today. It is believed that Navan was a pagan ceremonial site and was regarded as a sacred space. It features prominently in Irish mythology, especially in the tales of the Ulster Cycle. According to the Oxford Dictionary of Celtic Mythology, "the [Eamhain Mhacha] of myth and legend is a far grander and mysterious place than archeological excavation supports".
Natural building or ecological building is a discipline within the more comprehensive scope of green building, sustainable architecture as well as sustainable and ecological design that promotes the construction of buildings using sustainable processes and locally available natural materials.
A hut is a small dwelling, which may be constructed of various local materials. Huts are a type of vernacular architecture because they are built of readily available materials such as wood, snow, ice, stone, grass, palm leaves, branches, clay, hides, fabric, or mud using techniques passed down through the generations.

The Low German house or Fachhallenhaus is a type of timber-framed farmhouse found in northern Germany and the easternmost Netherlands, which combines living quarters, byre and barn under one roof. It is built as a large hall with bays on the sides for livestock and storage and with the living accommodation at one end.
The Geestharden house, also called the Cimbrian house, Schleswig house, Slesvig house or Southern Jutland house due to its geographical spread in Jutland, is one of three basic forms on which the many farmhouse types in the north German state of Schleswig-Holstein are based. The other two basic designs are the Gulf house and the Low German hall house. By far the best known variant of the Geestharden house is the Uthland-Frisian house, which is also referred to as the Frisian house (Friesenhaus).
Rumah adat are traditional houses built in any of the vernacular architecture styles of Indonesia, collectively belonging to the Austronesian architecture. The traditional houses and settlements of the several hundreds ethnic groups of Indonesia are extremely varied and all have their own specific history. It is the Indonesian variants of the whole Austronesian architecture found all over places where Austronesian people inhabited from the Pacific to Madagascar each having their own history, culture and style.
The hall house is a type of vernacular house traditional in many parts of England, Wales, Ireland and lowland Scotland, as well as northern Europe, during the Middle Ages, centring on a hall. Usually timber-framed, some high status examples were built in stone.
In archaeology, a hut circle is a circular or oval depression in the ground which may or may not have a low stone wall around it that used to be the foundation of a round house. The superstructure of such a house would have been made of timber and thatch. They are numerous in parts of upland Britain and most date to around the 2nd century BC.
