Bamboo (Bambuseae) is a tribe of flowering perennial evergreen plants in the grass family Poaceae, subfamily Bambusoideae, tribe Bambuseae; although, the forestry services and departments of many countries where bamboo is utilized as a building material consider bamboo to be a forestry product, and it is specifically harvested as a tree exclusively for the wood it produces, which in many ways is a wood superior in strength and resilience to other natural, fibrous building materials.In fact it is often referred to as a tree by cultures who harvest it as wood. Giant bamboos are the largest members of the grass family. In bamboos, the internodal regions of the stem are hollow and the vascular bundles in the cross section are scattered throughout the stem instead of in a cylindrical arrangement. The dicotyledonous woody xylem is also absent. The absence of secondary growth wood causes the stems of monocots, even of palms and large bamboos, to be columnar rather than tapering.Bamboos are some of the fastest-growing plants in the world,due to a unique rhizome-dependent system. Certain species of bamboo can grow 35 inches within a 24-hour period, at a rate of 3 cm/h (a growth of approximately 1 millimeter (or 0.02 inches) every 2 minutes). Bamboos are of notable economic and cultural significance in South Asia, Southeast Asia and East Asia, being used for building materials, as a food source, and as a versatile raw product. Bamboo has a higher compressive strength than wood, brick or concrete and a tensile strength that rivals steel.
The word bamboo comes from the Kannada term bambu, which was introduced to English through Malay.
Construction
Further information: Bamboo construction
Bamboo, like true wood, is a natural composite material with a high strength-to-weight ratio useful for structures.
In its natural form, bamboo as a construction material is traditionally associated with the cultures of South Asia, East Asia and the South Pacific, to some extent in Central and South America, and by extension in the aesthetic of Tiki culture. In China and India, bamboo was used to hold up simple suspension bridges, either by making cables of split bamboo or twisting whole culms of sufficiently pliable bamboo together. One such bridge in the area of Qian-Xian is referenced in writings dating back to 960 AD and may have stood since as far back as the third century BC, due largely to continuous maintenance.
Bamboo has also long been used as scaffolding; the practice has been banned in China for buildings over six stories, but is still in continuous use for skyscrapers in Hong Kong.In the Philippines, the nipa hut is a fairly typical example of the most basic sort of housing where bamboo is used; the walls are split and woven bamboo, and bamboo slats and poles may be used as its support.

Bamboo is a versatile building material that is strong, renewable, and environmentally friendly. It can be used for structural and non-structural building elements like walls, floors, ceilings, trusses, and more. Bamboo is graded based on traits like straightness, taper, and nodes. Proper selection of mature bamboo with a minimum diameter and wall thickness is important. Foundations can include direct ground contact, rock footings, or incorporating bamboo into concrete. Floors and walls are constructed using bamboo panels, joints, and infill. While bamboo construction has benefits of affordability, sustainability, and cultural acceptability, it lacks natural durability and is susceptible to insects without treatment.
This document provides details about the River Song Apartment housing project in Kollam, Kerala. It was designed by students from the School of Architecture. The project consists of a villament block and 6 split-level villas situated on a hillock overlooking valleys. Emphasis was placed on minimizing the building footprint and maximizing open green space. Sustainable design principles like optimal ventilation, natural lighting, and reuse of materials were incorporated.
Wattle and daub, willow weaving, thatch, cob, and lime mortar were traditional building methods used in Britain. Wattle and daub involved weaving wooden lattices and filling them with mud or clay. Willow weaving was used to make fences, furniture and even house walls by twisting willow branches. Thatch used reeds or straw as roofing material. Cob construction used a mixture of soil, straw, and water to build walls. Lime mortar was composed of limestone, sand, and water to bind bricks and stones before modern cement was available. These methods required locally available natural materials and skills passed down over generations.
The document summarizes Charles Correa's incremental housing project in CBD Belapur, India. It describes the project's low-cost housing typologies designed around communal courtyards. Housing was organized into clusters of 7-12 pairs of freestanding homes arranged around shared spaces. This allowed residents to independently modify their own homes over time. While many original structures have been replaced, the hierarchy of community spaces remains intact decades later. The project demonstrated high-density affordable housing built at a human scale with simple materials. However, maintaining common spaces and adapting to changing aspirations have presented challenges over time.

There are two main types of bamboo: sympodial and monopodial. Sympodial bamboo grows in dense clumps and produces new culms from the outer layers, while monopodial bamboo spreads via underground rhizomes and produces individual culms. In India, sympodial bamboo makes up over 67% of the bamboo stock and includes common species like Dendrocalamus strictus. The document provides statistics on bamboo growth in India between 2000 and 2005 and details on characteristics of different bamboo species.
Bamboo has a long history of diverse uses. It was used in early light bulbs, phonographs, and as reinforcement in concrete. Today, over a billion people live in bamboo houses. Bamboo is one of the strongest and most versatile building materials - it is very strong yet lightweight, flexible, and a rapidly renewable resource. Bamboo can be harvested much faster than trees, within 3-5 years, and continues regrowing thereafter without killing the plant. It has numerous environmental benefits including being very effective for erosion control, soil improvement, carbon sequestration, oxygen production, and watershed management. Bamboo also has many traditional and current uses for materials, tools, medicine, food, and more.
Bamboo House is located in Uppal. It is an organization based in India that works with bamboo. This document appears to be a thank you note from Bamboo House acknowledging the recipient.
There are two main types of bamboo: sympodial and monopodial. Sympodial bamboo grows in clumps and produces culms faster, while monopodial bamboo spreads via underground rhizomes.
