Torogan
View on Wikipedia

A torogan (lit. 'resting place' or 'sleeping place') is a type of pre-colonial vernacular house of the Maranao people of the Philippines.[1] A torogan was a symbol of high social status. They were very large buildings and served as the residence to a datu of a Maranao community, along with his retainers and their families. Nowadays, concrete houses are found all over Maranaw communities, but there remain torogans a hundred years old. The best-known are in Dayawan and Marawi City, and around Lake Lanao.
Description
[edit]Torogan are massive structures built entirely without using nails. Instead, they use fitted joints and fiber lashings. They are usually the biggest structure in a village. They are elevated from the ground on large wooden columns, not all of them load-bearing. There are usually around 25 columns, but very large torogan can have as many as 56. Each column is made out of a single huge tree trunk, often transported over long distances from forests. The raising of the columns are individually celebrated by feasts. The corner (tukud) and front posts and the middle (tapuwilih) row of posts are intricately carved in okir designs painted in bright primary colors. Each post is supported at the base by five or six large boulders for protection against earthquakes, with one directly beneath it to prevent direct contact with the ground and inhibit rotting and termites. Each is usually capped at the top end with larger-diameter stone boulders that prevent vermin from entering the house.[1]

Beams and a wooden floor (lantay) are then laid over the columns on which the main structure is built. The end of the beams (which are built facing east) are decorated with large wing-like carved wooden slabs called panolong (literally "prow"), which are representations of the same designs on the prows of the traditional Maranao boats (awang). They deliberately give the entire structure the appearance of a floating royal vessel held up by several canoes. The panolong are usually intricately carved with niyaga (also transcribed as naga or niaga, a mythical sea serpent) with open mouths, and other flowing okir designs. Each panolong has a different design, with the sixth one usually having a curling piyako (also pako or piako, "fern") motif. Smaller and less intricately carved panolong may also be found on the front left and front right sides of a torogan, especially those owned by powerful leaders. Carvings are also found beneath the window sills and on window and door frames. The narrow windows and doors are traditionally opened and closed by sliding them to the left or right along a wooden channel, a design type called sinongod. These are traditionally "locked" with pieces of wood that prevent them from sliding open.[1]
The main floor (poro) has a square floor plan. It has no permanent partitions and no ceiling, and thus appears as a large hall. It is used both for sleeping and other activities. During night time, mattresses (made from straw and woven mats) and pillows are brought out and the interior is separated into "rooms" for sleeping by hand-embroidered colorful cloth dividers, rattan or split-bamboo screens, and thick bed curtains (kolambo, which also serve as mosquito nets) for privacy. These are usually hung from horizontal cloth sheets hung directly from the rafters, thus forming tent-like structures. Multiple families live inside a torogan, with the main "rooms" being that of the leader and his family. Indentured servants and slaves and their family have "rooms" in the back near the kitchen area, while the family in charge of protecting the leader have their "rooms" near the entrance. A kulintang ensemble is also usually present near the leader's bedroom. Each "room" is bordered inside the cloth dividers with rows of wooden chests, brassware (gador), porcelain (solang), and other furniture which serve as containers for personal belongings (including weapons), artwork, food, and water. The actual walls of the torogan are also decorated with various types of patterned woven cloth.[1]
During daytime, most of the beds and dividers are cleared and the space is used for working (like weaving textiles), eating, praying, or meeting visitors. Activities are usually kept to a minimum early in the morning when some "rooms" are still up, but gradually become busier as all the occupants wake up. A kitchen area is located at the back of the torogan, with the floor about half a meter lower than the rest of the space. It contains a rectangular bamboo platform called the bantolang filled with earth and ashes that serves as a fireplace. Each bantolang can usually hold two datola, which is an arrangement of three small rocks on which cooking vessels are placed. On top of the bantolang is a bamboo rack called the tapaan, which is where fish or meat is smoked for preservation. Baskets with covers (called balengkat) are also hung on horizontal bamboo poles (tabak) on one side of the kitchen, and are used as food storage. Water for cooking and drinking is stored on bamboo containers called laya which are hung on the kitchen walls. Torogan are usually built near the shores of Lake Lanao, so the bathroom and toilet facilities are on adjacent structures (most notably the diamban, which is a platform built over the water used for bathing). The torogan also has an internal bathroom which is simply an enclosed space with a narrow slit on the floor and a clay jar of water. [1]
Torogan have a distinctively shaped hip-and-gable roof made from thatched palm leaves. The flaring edges taper shallowly towards a steep central gable aligned to the east. The central gable is supported internally by vertical posts called pulaos bungan, which in turn is supported by the intricately carved central beam of the roof called the tinai a walai (literally "intestine of the house"). The torogan was also surrounded by a wide open space called the lama, where other activities are also held. The lama commonly had a horse-racing track crossing it, called the paso-ay. The area beneath the main floor is called the dorung, which is also used for various purposes like storage or keeping domestic animals.[1]
Cultural significance
[edit]Torogan are pre-colonial and date to before the conversion of the Maranao people to Islam (which happened during the Spanish colonial period). They were of great importance to Maranao communities and were symbols of wealth and power. They primarily served as the residence of the leader of a community, ranging from village leaders (datu) to the sultans of the federation of Maranao states. Audience with the leader is usually done inside the torogan. Most visitors speak with the leader from the lower part of the bed nearest to the door (an area known as the dasigan). Favored guests, on the other hand, are usually invited to sit or lie down on the mattress itself (the sendigan), which is regarded as a place of honor. Torogan and their grounds also serve as the community social hall where feasts, weddings, games, funerals, meetings, and other social and cultural activities are held.[1]
Conservation
[edit]
The Kawayan Torogan, built by Sultan sa Kawayan Makaantal in Bubung Malanding, Marantao, Lanao del Sur, the last remaining habitable torogan, was declared as a National Cultural Treasure by the National Museum of the Philippines in 2008.[2]
There are also existing torogans in various locations in Lanao such as the Dayawan Torogan of Marawi and Laguindab Torogan of Ganassi. All are in need of massive funding for their rehabilitation. These collection of torogans from various towns in Lanao are being pushed to be included in the tentative list of the Philippines in the UNESCO World Heritage List.[3]
A torogan built in 1873 in Lanao del Sur for a Maranao nobleman, Togoran I Sabino Lakowa, has also been purchased and restored by the private park and resort hotel Las Casas Filipinas de Acuzar in Bataan, and is now part of the Casa Maranao exhibition. Like other similar purchases, this has been met with some criticism due to the relocation and commercialization of heritage houses. However, Las Casas Filipinas has defended the relocations as the only way to restore and preserve the heritage houses for future generations, which in most cases were neglected and decaying in their original locations.[4][5]

Torogan
View on GrokipediaOrigins and Historical Context
Pre-Colonial Development
The Torogan emerged among the Maranao people inhabiting the region around Lake Lanao in Mindanao, Philippines, as a distinctive form of vernacular architecture predating widespread Spanish influence in the 16th century. Rooted in the Austronesian building traditions of elevated, post-and-beam structures, it served as the primary residence for elites within a kinship-based society characterized by independent barangay units led by datus.[4] This hierarchical organization, with datus holding authority over extended families and resources, necessitated larger dwellings to accommodate communal living and display prestige, distinguishing the Torogan from smaller, simpler commoner houses used by non-elites.[5] Prior to the full Islamization of the Maranao, which intensified in the 17th century following initial contacts in the 1450s via Sulu traders, Torogan design incorporated animist cosmological elements through motifs depicting natural forms and mythical creatures like the sarimanok, symbolizing spiritual protection and ancestral ties.[4][6] Oral traditions preserved in Maranao folktales link these houses to royal lineages, portraying them as embodiments of datu power and communal harmony, though lacking precise dating due to the absence of pre-colonial written records.[7] Archaeological parallels with other Austronesian elevated houses in Southeast Asia suggest continuity from earlier migratory patterns, adapted locally to affirm governance structures amid inter-barangay alliances and rivalries.[8] Construction techniques emphasized resilience to the Lanao region's seismic activity and seasonal flooding from the lake, featuring massive wooden posts from durable hardwoods sunk deep into the ground and flexible bamboo framing to absorb shocks, as evidenced by enduring examples and ethnographic accounts.[1][3] The steep, thatched roofs of cogon grass or nipa provided ventilation against tropical humidity while repelling heavy rains, reflecting pragmatic adaptations informed by empirical observation rather than imported designs. Early Islamic influences post-14th century, transmitted through trade, began integrating non-figural geometric okir patterns, yet the core form remained tied to indigenous animist priorities of harmony with nature and elevation above earthly perils.[9]Key Historical Examples and Sites
The Dayawan Torogan, located in Barangay Dayawan, Marawi City, represents one of the oldest known examples, originally constructed around 1740 as a royal clan house for Maranao elites.[10] It endured through various historical episodes in Lanao but ultimately deteriorated due to age, environmental factors, and neglect by the late 20th century.[10] The Kawayan Torogan in Bubung Malanding, Marantao, Lanao del Sur, built by Sultan sa Kawayan Makaantal, exemplifies a well-preserved historical site and the last remaining habitable torogan of its kind.[2] Declared a National Cultural Treasure by the National Museum of the Philippines in 2008 via Museum Declaration No. 4-2008, it underscores the architecture's cultural significance and the need for ongoing rehabilitation to maintain structural integrity.[1][11] Several other torogans in Marawi City, some over a century old, highlight the regional concentration of these structures prior to modern disruptions. The 2017 Siege of Marawi inflicted extensive damage across the city, compromising the historical integrity of remaining sites through destruction of surrounding heritage contexts and physical impacts on buildings.[12]
Architectural Design and Features
Structural Elements
The Torogan features a stilt-elevated design, with the structure raised on massive wooden posts crafted from whole tree trunks, typically positioned to lift the floor approximately two meters above ground level. This elevation provides protection against flooding in the low-lying regions of Lanao del Sur, allowing water to pass beneath without damage to the living space. The posts, numbering between nine and twelve depending on house size, support the entire load through interlocking joints rather than nails, enabling flexibility during seismic activity.[1][13] Internally, the Torogan employs an open-plan layout devoid of permanent walls, forming a single expansive room measuring roughly 8 to 19 meters in length. Hardwood posts and beams, including a central tie beam known as the tinai a walai or "intestine of the house," bear the structural weight and connect to king posts that uphold the roof framework. This post-and-beam system distributes forces evenly, minimizing stress concentrations and enhancing overall stability without reliance on rigid partitions.[14][15] The roof consists of wide, steeply sloping gables covered in thatch, often from cogon grass or bamboo, which facilitate rapid runoff during heavy rains prevalent in Mindanao. These expansive eaves extend outward to shield walls from prolonged exposure to tropical downpours, while the pitched angle promotes ventilation beneath. The nail-free assembly of lashed fibers and fitted timbers allows the roof to sway independently during earthquakes, reducing the risk of catastrophic failure compared to inflexible modern concrete roofs that can crack under lateral forces.[16] Empirical evidence of the Torogan's resilience is evident in surviving examples that withstood typhoons and seismic events in the Philippines, where traditional wooden flexibility outperforms rigid materials by absorbing shocks through movement rather than resisting them. Post-disaster assessments highlight how elevated, jointed designs mitigate flood and quake damage, as rigid concrete structures often collapse under similar conditions due to brittleness.[3][17]Decorative and Symbolic Motifs
The panolong, wing-like protruding beams extending from the front and sides of the Torogan, serve as the most prominent decorative elements, typically numbering seven or more and carved with intricate okir patterns combining floral motifs and representations of the naga, a mythical dragon or serpent.[18] These designs, exclusive to elite structures like the Torogan, symbolize power, rank, and leadership, distinguishing the residence of a datu or sultan from ordinary dwellings and reinforcing the owner's elevated social status through visible opulence.[18][1] Okir carvings adorn both exterior and interior surfaces, featuring stylized motifs such as the S-curved naga for protection and authority, pako lungat fern leaves denoting growth, and floral elements like obarobar evoking beauty and abundance, drawn from pre-Islamic animistic reverence for nature while adapted to Islamic prohibitions on idolatry through geometric abstraction.[19][19] The naga motif, in particular, evokes guardianship against evil, blending indigenous cosmological beliefs with post-conversion Islamic geometric influences evident in the curvilinear yet non-figurative styling.[19][1] These motifs, executed in hardwoods by skilled Maranao artisans, not only enhance aesthetic appeal but also encode cultural identity, with the Torogan acting as a repository for virtually all known okir variations, underscoring the structure's role in displaying hereditary prestige without overlapping functional supports.[1] Vibrant colors such as red and yellow, applied in some preserved examples, further align with Islamic symbolic associations, amplifying the motifs' role in communal rituals and elite assertion.[19]Construction Methods and Materials
Traditional Building Techniques
![Model of a Torogan][float-right] The construction of a Torogan relied on nail-less joinery techniques, employing interlocking timbers, wooden pegs, and lashings to assemble the structure, ensuring flexibility and durability against environmental stresses such as earthquakes and floods.[3][20] This method demanded high skill from master carpenters, referred to as panday, who led the process using knowledge passed down through generations via oral tradition rather than written blueprints, resulting in regional variations while maintaining fundamental principles for structural integrity.[21][22] The building process began with site selection on elevated, well-drained terrain to mitigate flooding risks, followed by the erection of foundational posts secured on boulders or half-buried stones for stability and seismic resilience.[3][23] Assembly involved hierarchical teams of artisans under the panday's direction, often spanning several months of labor-intensive work commissioned by elite patrons such as datus, with community participation incorporating rituals to invoke prosperity and protection.[1] Post-assembly, the structure's robustness was traditionally verified through physical tests, such as staging mock conflicts inside to assess load-bearing capacity and joint security, underscoring the empirical approach to ensuring longevity in a seismically active region.[3] This communal and skill-based methodology not only facilitated the Torogan's endurance but also reinforced social hierarchies, as the panday's expertise and the patron's resources determined the scale and refinement of the final edifice.[1]Sourcing and Use of Materials
The primary structural elements of the Torogan, including its elevated posts and beams, were constructed from durable hardwoods such as narra (Pterocarpus indicus) and yakal (Shorea astylosa), harvested from forests proximate to Lake Lanao in the pre-colonial Maranao homeland.[24][25] These species were selected for their density and load-bearing capacity, with narra exhibiting natural resistance to decay and insect damage due to its extractive content, enabling the house's longevity in tropical conditions.[26] Roofing materials comprised thick thatch layers of cogon grass (Imperata cylindrica), gathered from surrounding wetlands and grasslands, which provided effective waterproofing and thermal regulation without requiring processing.[1][3] Auxiliary components like walls and lashings utilized locally abundant bamboo and rattan, ensuring all resources aligned with the Maranao's self-reliant economy prior to colonial influences.[27] This reliance on indigenous, renewable sources underscored the Torogan's environmental integration, minimizing transport demands and fostering sustainability through cyclical harvesting practices.[28] However, despite the inherent durability of selected hardwoods, vulnerability to termite infestation and fungal degradation in high-humidity settings posed long-term risks, as evidenced by accelerated wood breakdown in untreated tropical timbers.[29][26]Cultural and Social Role
Symbolism of Status and Power
The Torogan functioned as a tangible manifestation of Maranao social stratification, accessible solely to the ruling elite comprising sultans and datus, thereby encapsulating their genealogical superiority, authoritative command, and material affluence in a patrilineal kinship system.[30][16][10] Erection of a Torogan demanded substantial communal labor and resources, restricted to those of paramount lineage, which visibly differentiated noble residences from the simpler abodes of commoners and reinforced hierarchical distinctions through architectural prominence.[10][31] Its expansive dimensions, frequently exceeding those of vernacular houses, enabled the housing of retainers and dependents, projecting the datu's or sultan's prowess in patronage networks and resource allocation as markers of unchallenged dominion.[32][31] Profuse ornamentation, including okir carvings on panolong projections, served as codified emblems of prestige, with the complexity and vibrancy of motifs—often evoking protective serpentine guardians—betokening the elite's monopolization of skilled craftsmanship and symbolic capital.[30][33] While the sultanate framework, introduced via Islamization commencing in the 14th century, amplified the Torogan's association with monarchical titles, its foundational design and status-conferring role persisted from antecedent pre-Islamic warrior aristocracies, attesting to resilient indigenous power paradigms amid exogenous influences.[5][34]Community and Ritual Functions
The Torogan functioned as a central venue for major social events among the Maranao, including weddings, feasts, and death rituals, where extended kin, allies, and community members gathered in its expansive interior to accommodate large assemblies.[30] [5] These occasions often featured communal merrymaking with traditional music ensembles such as kulintang gongs and bayok chants, reinforcing social bonds through shared participation.[30] In governance and conflict management, the Torogan served as the site for dispute resolutions presided over by sultans or datus, hosting assemblies like bitiara for community welfare discussions and mediation of inter-clan tensions, including practices akin to resolving rido feuds via elder councils.[5] [30] Ethnographic accounts highlight its role in maintaining clan cohesion by providing a neutral space for negotiation and reciprocity, such as katatabanga mutual aid, amid historical patterns of inter-group conflicts in Lanao regions.[5] Ritual practices within the Torogan invoked ancestral and spiritual elements during events like enthronements and funerals, with spatial arrangements including separate upper chambers (lamin) for women reflecting traditional seclusion norms that segregated genders during ceremonies.[1] [30] These functions underscored the structure's utility in preserving Maranao adat customs, as documented in sultanate-era ethnographies from the early 20th century onward.[5] ![Model of a Torogan illustrating communal spaces][center]Preservation and Challenges
Threats to Existing Structures
Torogans, constructed primarily from hardwood timbers such as narra and yakal, face significant biological degradation from termite infestations and fungal wood rot, exacerbated by the humid tropical climate of Mindanao. Termites, prevalent in the Philippines due to abundant cellulose sources and soil moisture, bore into structural posts and beams, compromising load-bearing elements over time.[36][37] Wood rot further accelerates deterioration through moisture accumulation in poorly ventilated or exposed sections, leading to fungal decay that softens timber and invites collapse.[21] Neglect stemming from post-20th-century urbanization has intensified structural weakening, as Maranao families increasingly relocate to concrete dwellings in expanding cities like Marawi, abandoning traditional houses without maintenance. This shift prioritizes modern materials over wooden ones, resulting in unchecked exposure to environmental elements and loss of artisanal repair knowledge.[38] The Dayawan Torogan in Marawi exemplifies this, having deteriorated into a state of advanced decay after abandonment, with its timbers succumbing to weathering and lack of intervention despite its historical significance dating to the 18th century.[39][10] Human-induced damage from armed conflicts compounds these risks, as seen in the 2017 Marawi siege, where intense urban fighting between government forces and Islamist militants destroyed or endangered cultural sites in the Maranao heartland, including Torogans exposed to shelling and arson. Land disputes among heirs or communities have also prompted demolition or repurposing of unoccupied structures, further eroding the remaining inventory estimated at fewer than a dozen intact examples by the early 21st century.[40] Despite inherent design resilience—such as elevated stilts mitigating ground-level moisture and termite access—the dominance of concrete construction in urban areas has severed intergenerational transmission of preservation techniques, rendering surviving Torogans increasingly vulnerable to irreversible decline.[3][21]Conservation Efforts and Outcomes
The National Museum of the Philippines declared the Kawayan Torogan in Barangay Bubung Malanding, Marantao, Lanao del Sur, a National Cultural Treasure in 2008 through Museum Declaration No. 4-2008, recognizing it as the last standing pre-colonial example of Maranao royal architecture and urging immediate rehabilitation to prevent further deterioration.[1][2] This status aimed to facilitate funding from bodies like the National Commission for Culture and the Arts (NCCA), with officials such as anthropologist Jesus T. Peralta noting its potential to secure resources for preservation.[2] Earlier efforts included a 1993 resolution by the National Historical Institute (now National Historical Commission of the Philippines) highlighting the deteriorated state of a Torogan house built by Datu Pimbarat in Buadi Amito, Pompongan-a, and calling for conservation measures and restoration to halt its decline.[41] Local and community-driven initiatives have supplemented state actions, such as volunteer-led repainting of okir designs on Torogan structures in Davao City's Kadayawan Village in July 2023, preparing them for cultural festivals and demonstrating grassroots involvement in maintenance.[42] Outcomes remain mixed, with partial successes overshadowed by persistent challenges. The Dayawan Torogan in Tuca, Lanao del Sur, which had severely decayed by 2011 due to neglect by preservation agencies, underwent restoration by 2018, restoring some structural integrity and okir elements.[39][10] However, the Kawayan Torogan, despite its 2008 designation, exhibited ongoing deterioration as of September 2024, prompting renewed calls for government or private intervention amid reports of bureaucratic delays and inadequate funding that have hindered comprehensive repairs.[43] These cases underscore a shift from traditional community self-reliance in upkeep—rooted in familial and royal obligations—to reliance on state mechanisms, which have proven inconsistently effective in delivering timely outcomes.[2]Modern Adaptations and Legacy
Contemporary Revivals and Influences
In recent years, the Bangsamoro Autonomous Region in Muslim Mindanao (BARMM) has incorporated Torogan-inspired elements into public infrastructure, notably through the construction of barangay halls that adapt traditional Maranao architectural features for administrative use. These projects, initiated around 2023, feature prominent panolong (projecting house beams) and okir (curvilinear motifs) carvings on facades, drawing from the royal Torogan's symbolic grandeur to foster cultural identity in community governance spaces.[44] [45] For instance, the Balindong Barangay Halls in Lanao del Sur, designed by Architect Gloryrose Dy Metilla, blend wooden frameworks with concrete for durability while retaining elevated structures and intricate carvings, executed under BARMM's Ministry of Public Works leadership.[45] Similarly, the Nunguan Barangay Hall in Pikit, Cotabato, explicitly draws inspiration from Torogan proportions and ornamentation to integrate indigenous aesthetics into modern functionality.[46] These adaptations extend to educational and tourism initiatives aimed at countering urbanization's erosion of traditional knowledge. Replicas and scaled models of Torogan houses appear in regional museums and cultural centers, such as those promoted by Mindanao heritage programs, to educate visitors on Maranao craftsmanship and history.[47] Such displays, often using lightweight materials for portability, have gained traction post-2010 amid tourism pushes in BARMM, highlighting okir motifs and structural elevation to attract domestic and international interest while preserving intangible cultural elements.[44] However, these contemporary revivals face scrutiny over authenticity, as scaled-down versions in barangay halls—typically 10-15 meters wide versus the original Torogan's 30+ meters—inevitably dilute the imposing scale and communal spaciousness that signified datu status.[45] Modern substitutions like steel reinforcements for hardwood further deviate from vernacular post-and-beam systems, potentially compromising the flexible, earthquake-resistant qualities inherent in traditional designs, which elevated floors and tied joints allowed survival in seismic events up to magnitude 7.[3] Despite this, architects advocate for Torogan-derived models in disaster-prone areas, citing their proven resilience—evidenced by surviving 19th-century quakes—as a basis for hybrid builds that could inform resilient housing in the Philippines' typhoon- and fault-line regions, provided fidelity to load-distributing principles is maintained.[3]Comparative Architectural Insights
The Torogan shares functional similarities with other Southeast Asian stilt houses, such as traditional Malay dwellings, in its elevation on massive wooden posts to resist flooding, deter vermin, and promote natural ventilation in humid tropical climates.[3][48] This elevation, often 2-3 meters high in Torogan structures, parallels the stilt foundations in Malay houses, which similarly elevate living spaces above ground level to mitigate seasonal inundation and soil moisture.[3] However, the Torogan's scale sets it apart, with its expansive single-room interior spanning up to 20 meters in length and featuring steeply pitched roofs rising to 10 meters or more, enabling communal gatherings for elite families—contrasting the more modular, compact layouts of typical Malay houses designed for nuclear households.[1] Aesthetically, the Torogan's okir motifs—intricate, curvilinear wood carvings depicting stylized flora and naga (serpentine) elements—emphasize permanence and cultural specificity in architectural embellishment, differing from the transient, dye-based batik patterns prevalent in Indonesian and Malay textile traditions, which prioritize wearable symbolism over structural integration.[49] These okir designs, executed in hardwood panels without metal fasteners, underscore the Torogan's reliance on joinery for seismic flexibility, a principle echoed in Sub-Saharan African vernacular architecture, where interlocking wooden frameworks in structures like Ethiopian rock-hewn adaptations or West African granary systems prioritize elastic resilience over rigid masonry to withstand environmental stresses.[50] Analyses from 2025 highlight these parallels as outcomes of convergent environmental necessities rather than diffusion, with both traditions favoring lashings and pegs for durability in resource-scarce settings.[50] In contrast to the colonial-era bahay kubo, a ubiquitous Filipino vernacular house for commoners, the Torogan demonstrates enhanced elite symbolism and structural longevity through its nail-free assembly of rattan-tied beams and posts, which absorb shocks from earthquakes and typhoons more effectively than the bahay kubo's lighter bamboo framework.[9] While both employ stilts for flood elevation—typically 1-2 meters in bahay kubo—the Torogan's larger footprint and panultihan (decorative end-beams) project datu authority and wealth, critiquing the bahay kubo's constrained scale and utilitarian focus, which limited it to agrarian households without comparable hierarchical display.[9][51] This durability edge stems from the Torogan's use of durable hardwoods like narra, lashed for flexibility, versus the bahay kubo's reliance on perishable nipa thatch and bamboo, rendering the latter more prone to rapid decay in wet conditions.[1]References
