A number of different styles have been developed across the world; some of them are relatively new, while others have a history of centuries (if not millennia).
Typical of the Third Imperial Period (300-564 AB) and early Iron Period (564-730 AB) in Ilocan, as well as modern Ictzecco and Roamu. Polygonal stones and ashlar are used extensively, as are trapezoidal doorways. Temples and palaces are trapezoidal pyramid shapes with platforms atop them, carved with exquisite friezes and surrounded by large courtyards.
Inspired by the simplicity and elegance of the new abbeys of Llegramu (themselves derived from peasant houses), popular in Durnhão since the late Proselytization Period (650-700 AB). Multi-storey houses with simple balconies, arches between exterior columns, tiled roofs, and exteriors in bright hues (typically one hue per house) but no niches for statues—a simpler use of techniques in older styles. Used in residences, workshops, government buildings, and abbeys.
Found in Duway, Girradjaw, and Arumandjee since the late League Era (300-498 AB), still very popular. Buildings are quite spartan outside and in, but decorated in delicately contrasting colours as a show of understated wealth, around a central courtyard. Plain glass windows are a true luxury item; plain white pillars, only slightly less so. Typical of large urban homes and newer government buildings.
Found in Einir, the oesg (plural wysg) is an enclosed, fortified building, typically circular or rectangular, with a wide courtyard and rooms built into the central structure. Functions as a fort and living space in one. Typical in rural areas, as well as in the design of older cities.
Used across the history of Nukambi, but most popular during the Kamirran Era (977-638 BC). Buildings are tall and airy, decorated with stained-glass windows and glass mosaics depicting nature and mythological scenes; when glass is not useable, painted stones or wood are very much in vogue. Used primarily on temples and public palace areas, but also in some private homes.
Practiced by the people of Yashdar during the Rajjid Period (835-512 BC). "Compass domes"—domes surrounded on four sides by barrel-vault passages—are the most popular architectural element, in large part due to the skill needed to design them; houses tend to be high and flat-roofed, accessible via the street. Stone, clay, and wood all see much use.
Inhabitants of Verna's mountainous regions have been living in caves since prehistory, but the first real sunyari ("making of a place") architecture, where artificial caves are carved out of the landscape to make homes and temples, appeared in the early Classical Age (981-650 BC). Sunyari is quite popular with Ashkas of the Vesudonta School.
A vernacular style of architecture found in the marshes of eastern Yashdar, the susuna itself is a large building made of reeds, used by the Tharrabad as a guest-house and village hall. The long barrow-style structure inspired by this is also called susuna, although it was most popular during the Formative Era (3500-2000 BC) and is today mostly found in ruins.
Practiced by the ancient Truzithans (1600-753 BC), the houses and temples tended to be circular, with conical roofs and (typically) columns around the central structure. Once made from wood and thatch, later buildings were constructed from local limestone and marble, with ceramic tiles on the floors. This style would inform the later Voerian and Einirian schools of architecture.
Found in temples and houses of various sorts across Sayintha, uppujektha ("the making of a mountain by building") relies on multi-tier pyramid shapes atop relatively low, flat buildings. Stone is often preferred for such buildings, although pagodas of wood are not uncommon.
Typical of the late Iron Period (730 AB to the present day) in Ilocan, Acuitlan, and Palpan. The trapezoidal pyramid shapes of old are maintained, but hollowed out and painted a brilliant white (yoquitzah means "whitening" in Motzalac), with large windows and balconies facing south. Roofs are tiled rather than thatched.
