# Bahay kubo

The báhay kúbo, kubo, or payág (in the Visayan languages), is a type of stilt house indigenous to the Philippines. Often serving as an icon of Philippine culture, its design heavily influenced the Spanish colonial-era bahay na bato architecture.

## Etymology

The Filipino term báhay kúbo roughly means "country house", from Tagalog. The term báhay ("house") is derived from Proto-Malayo-Polynesian *balay referring to "public building" or "community house"; while the term kúbo ("hut" or "[one-room] country hut") is from Proto-Malayo-Polynesian *kubu, "field hut [in rice fields]".
The term "nipa hut", introduced during the Philippines' American colonial era, refers to the hut version of bahay kubo. While nipa leaves were the thatching (pawid) material often used for the roofs, not all bahay kubo are huts or used nipa materials.

## History
### Classical period (pre-Hispanic era)

Distinction between each tribes and cultures' style may have been more visible during the pre-hispanic period. Different architectural designs are present among each ethnolinguistic group in what is now the Philippines and throughout the Southeast Asia and Pacific as part of the whole Austronesian architecture.
They were designed to endure the climate and environment of the Philippines. These structures were temporary, made from plant materials like bamboo. The accessibility of the materials made it easier to rebuild when damaged by a storm or earthquake.

### Hispanic era

The advent of the Spanish colonial era introduced the idea of building more permanent communities around church and government centers.
Christianized peoples such as the Tagalogs, Visayans, Ilocanos, Kapampangans, Bicolanos, Cagayanons, Mestizos, Criollos, Chinese and Japanese were send to live in the lowlands. This established a community with most population of Austronesian origin, each having their own distinct traditions of Austronesian architecture, dating back even before the Hispanic period. They collectively evolved a style of construction that soon became synonymous with the lowland culture architecture known as bahay kubo.
Appearance varies from simple huts, later known by the Americans as nipa huts, to mansions like bahay na bato. Architectural designs and furnishings varied from standard Filipino, Chinese, Americas, European to eclectic.
The new community also setup made construction using heavier, more permanent materials desirable. Some of these materials included bricks, mortar, tiles and stone.
Finding European construction styles impractical in local conditions, Spanish and Filipino builders quickly adapted the characteristics of the bahay kubo and combined it with Spanish architectural style.

#### Bahay na bato

Bahay na bato developed from the bahay kubo with noticeable Spanish influence. Its design evolved throughout the ages but maintained its nipa hut architectural roots. Its most common appearance is like that of stilt nipa hut that stands on Spanish style stone blocks or bricks as a foundation instead of wood or bamboo stilts.
The bahay na bato, followed the nipa hut's arrangements such as open ventilation and elevated apartments. It was popular among the elite or middle class and integrated the characteristics of the nipa hut with the style, culture, and technology of Spanish architecture. The differences between the two houses were their foundational materials. The bahay na bato was constructed out of brick and stone rather than the traditional bamboo materials. It is a mixture of native Filipino, and Spanish influences.
During the 19th century, wealthy Filipinos built houses with solid stone foundations or brick lower walls, and overhanging. Wooden upper story/stories with balustrades. The ventanillas and capiz-shell sliding windows were both native Filipino influences on the design. The thatched nipa roof (pawid) is often replaced with Spanish-style curved clay tiles known as teja de curva.
Bahay na bato had a rectangular plan that reflected the Hispano-American Antillean architectural style integrated with traditional Philippine style. Today these houses are more commonly called ancestral houses.

## Characteristics

The hut was typically made of local building materials found in nature such as wood, bamboo and cogon grass. Similar to modern Feng shui, vernacular and superstitious reasons for the materials are considered.
The bahay kubo was elevated above ground or water on stilts as protection from pests, predators and floods, and usually consisted of one room where the whole family would dine, sleep and do other household activities; thus, access to the hut was by ladder. The roof was made of palm leaves smoked for waterproofing and consisted of long steep eaves to allow water to flow down more easily. The windows to the hut were large to allow cool air in. Similar conditions in Philippine lowland areas have led to characteristics "typical" of examples of bahay kubo.

### Bubóng (roof)

The traditional roof shape of the bahay kubo is tall and steeply pitched, with an apex called the "angkub" and long eaves descending from it. A tall roof creates space above the living area through which warm air could rise, giving the bahay kubo a natural cooling effect even during the dry season. The steep pitch allows water to flow down quickly at the height of the monsoon season while the long eaves give people a limited space to move about around the house's exterior when it rains. The steep pitch of the roofs is often used to explain why many bahay kubo survived the ash fall from the Mt. Pinatubo eruption, when more 'modern' houses collapsed from the weight of the ash.

### Sílong

Raised up on hardwood stilts which serve as the main posts of the house, bahay kubo have a silong (the Tagalog word also means "shadow") area under the living space for a number of reasons, the most important of which are to create a buffer area for rising waters during floods and to prevent pests such as rats from getting up to the living area. This section of the house is often used for storage, and sometimes for raising farm animals, and thus may or may not be fenced off.

### Silíd (living space)

The main living area is designed to let in as much fresh air and natural light as possible. Smaller bahay kubo will often have bamboo slat floors which allow cool air to flow into the living space from the silong below (in which case the silong is not usually used for items which produce strong smells). A bahay kubo may be built without an atip (ceiling) so that hot air can rise straight into the large area just beneath the roof and out through strategically placed vents.

#### Dingdíng (walls)

The walls are always of light material such as wood, bamboo rods, or bamboo mats called "amakan", "sawali", or “kalakat” in Cebuano. As such, they tend to let some coolness flow naturally through them during hot times and keep warmth in during the cold wet season.
The cube shape distinctive of the bahay kubo arises from the fact that it is easiest to pre-build the walls and then attach them to the wooden stilt-posts that serve as the corners of the house. The construction of a bahay kubo is therefore usually modular, with the wooden stilts established first, a floor frame built next, then wall frames, and finally, the roof.

#### Dungawán (windows)

Bahay kubo are typically built with large windows, to let in more air and natural light. The most traditional are large awning windows, held open by a wooden rod. Sliding windows are also common, made either with plain wood or with Capiz shell-panes which allow some light to enter the living area even with the windows closed. In more recent decades inexpensive jalousie windows became common.
In larger examples, the large upper windows may be augmented with smaller windows called ventanillas (Spanish for "little window") underneath, which can be opened for ventilation to let in additional air on especially hot days.

#### Batalán

Some bahay kubo, especially those built for long-term residences, feature a batalán ("wet area" or "pantaw") distinct from other sections of the house—usually jutting out somewhat from one of the walls. Sometimes at the same level as the living area and sometimes at ground level, the batalán can contain any combination of cooking and dishwashing area, bathing area and, in some cases, a lavatory.
Batalán used for cooking and washing dishes were known as banggéra in Philippine Spanish (also bánggerahán or pingganan). It is named after the bangá earthen water-jars which are placed on a jutting structure of spaced bamboo or wooden slats.

#### Kamálig

A granary detached from the house where harvested rice is kept.

### Construction materials

The walls of the living area are made of light materials. Posts, walls, and floors are typically made of wood or bamboo and other light materials. The thatched roof is often made of nipa, anahaw or some other locally plentiful plant. Thus, making it easier for the nipa huts to be moved if needed.

## Cultural significance

A nipa hut is an icon of Philippine culture as it represents the Filipino value of bayanihan, which refers to a spirit of communal unity or effort to achieve an objective.

### Arts

A famous folk song, "Bahay Kubo", is often sung in schools, and is about a small house surrounded by vegetables, reading thus:
   Bahay kubo, kahit munti, ang halaman doon ay sari-sari: singkamas at talong, sigarilyas at mani, sitaw, bataw, patani,
   Kundol, patola, upo't kalabasa, At saka mayroon pang labanos, mustasa, sibuyas, kamatis, bawang at luya. Sa paligid-ligid ay puno ng linga.
The song is a generalization of what a nipa hut would have looked like during the pre-colonial era: a house surrounded by locally cultivated plants. This does not take into account the early and diverse variants of native royalties, particularly those of the Mindanao region which has heavy Islamic architectural influences.

## Legacy

American architect and engineer William Le Baron Jenney visited the Philippines for three months in 1850. He noticed that during a storm, bahay kubo structures are very "light and flexible"; they only seem to dance and sway through storms. This inspired him to emulate the flexibility of bahay kubo in 1879 when he built the first lighter building. In 1884, he built the Home Insurance Building in Chicago, the first metal-framed skyscraper in the United States. Because of this, he became known as "The Father of Modern American Skyscrapers", and the Home Insurance building would become the predecessor of all the modern skyscrapers in the world, showing how important the bahay kubo is in history.
The bahay kubo also inspired architects such as Francisco Mañosa and Leandro Locsin by incorporating elements of the bahay na bato into their own designs especially seen in Cultural Center of the Philippines, National Arts Center, Coconut Palace, and Light Rail Transit stations.
