  • Background:
    Bamboo provides millions of households across the world with employment and building materials. It is often used as a fast-growing alternative to timber or other building materials, and its products can have a low or even negative carbon footprint across their lifecycle. Well-designed bamboo structures are known to withstand earthquakes and tropical storms remarkably well.

In recent years, the global modern bamboo construction sector has made remarkable achievements: hundreds of large commercial projects are built of bamboo. However, the capacity building of bamboo construction professionals lags behind the resources’ potential. IBCC2019 is an international competition aimed at university students of architecture, civil engineering, landscape and other construction related courses from across the world. The competition’s objective is to invite students to explore the potential construction applications for both bamboo poles and engineered bamboo products.


The 2019 Beijing Horticultural Expo will be held in Beijing, China from 29th April to 7th October, 2019. At this event INBAR will have a 3000 m2 Garden, which will house our own 1000 m2 Pavilion. The pavilion will be built from round bamboo poles and engineered bamboo products. INBAR believes that this an excellent opportunity to raise public awareness about bamboo’s potential in construction. And the IBCC2019 is a corner stone of this initiative.

Depends on a global expert group, INBAR Construction Task Force, which includes 28 bamboo construction experts from 18 countries, INBAR sincerely invites young students across the world to create bamboo houses in Beijing, China during 2019 Beijing Horticultural Expo.


This year’s competition is inspired by the 2019 Horticultural Expo and requires entrants to design the prototype for a multi-functional garden building with:

○  A construction area of 9 square metres (3 metres by 3 metres), as well as projection area no larger than 16 square metres (4 metres by 4 metres), including cantilever structural elements such as canopy. Plat concrete foundation is available for each project.

○   The building should be one or two stories, able to operate as an office, warehouse, educational space or relaxation suite such as drink corner.

○  The indoor temperature should remain pleasant throughout Beijing’s summer (around 23-28°C) without resort to mechanical ventilation or artificial cooling.

○  The building should be easily demountable, transportable and reusable; and though it is a temporary structure, the long-term durability of the structural members should be pursued. Detailing that keeps these members dry, drained and well-ventilated needs to be considered to achieve this goal.

○  The building is to be made mostly from bamboo poles and/or engineered bamboo products. A limited amount of other non-structural materials may be used, but only with the aim of enabling or enhancing bamboo’s potential, or where clearly bamboo is inappropriate. It should be assumed that only Phyllostachys pubscens (Moso bamboo) is available for bamboo poles, unless otherwise agreed with the organising committee. Engineered bamboo products available will be announced by the organising committee. The design strength values of engineered bamboo can be estimated as (if no data from manufactures available, in MPa):

Bending strengthCompression strengthTension strength
Shear strength along bamboo stripsElastic modulus E

○  The total budget for all building materials is US$10,000, and should not be exceeded. It must be buildable by a team of four people over three days (three 8 hour periods).

The three winning designs will be built at the Horticultural Expo 2019; therefore, the above points must be carefully observed.
