Bamboo teams are sized depending on each project between 6-22 craftsmen.
Depending on size, design and function of the building, it usually takes:
- Ground area: 0-100m2: 1 month.
- Ground area: 100-200m2: 2 months
- Ground area: >200m2: 3-6 months
1 – First meeting and review of the project based on architects drawings for a first estimation and timing of your project.
2 – Architectural drawings (1 – 6 months). Please look at partners to meet with the architect the most adapted to your project.
3 – Structural studies and small scale models in order to ensure stiffness, durability and define together the best options for your project. (2 weeks – 4 months) A related quotation as well as estimated planning of construction for the bamboo building will be proposed at this stage.
4 – Once contracts are signed and deposit done, we will prepare the bamboo material and teams, transport of material (1 – 2 months)
5 – Bamboo construction (1 – 6 months). The foundations should be built with a local contractor or partners before installing the bamboo structure. Electricity and plumbing can be prepared as well. (1 – 4 months)
- Bamboo columns
- Roof bamboo structure
- Finishing on bamboo structure
6 – Delivery of the bamboo structure, interiors and landscaping
7 – Grand Opening!
Bamboo poles have a natural layer of silicate on the top skin which protect against fire. The borax – boric salts used for the treatment add an extra protection.
For specific requirements an extra coating of fire protection can be applied on top of the bamboo poles.
Here are the 2 products we propose to applied (non exhaustive):

In order to comply with Indonesian legislation and standards of construction (SNI 1727: 2013), a wind speed of 140,8km/hrs (39,1m/s) for strength design and 115,2km/hrs for serviceability design are considered. For projects outside of Indonesia, the local standards for wind speed will be applied.
As the bamboo is light and flexible, bamboo buildings are more resistant to earthquakes in comparison with other types of buildings. The coefficient of Fail Safe (Express the ability to withstand very strong external accidental stresses) will be 2,5 superior for bamboo than steel and timber structures and 5 times more than concrete buildings.
Depending on the category and location of the building, a seismic verification would be needed. For Indonesia, the level of importance regarding earthquakes is given on the national maps (SNI 1726: 2012). For other countries, we will comply with local legislation regarding earthquakes when required.
We calculate the bamboo structure following international bamboo standards developed by INBAR (International Network for Bamboo and Rattan) based on Eurocodes calculation for timber structures. A 3D structural model including wind forces simulation is done to ensure the stability of the structure.
As bamboo is a natural material, it is usually allowed to build bamboo buildings in agroforestry areas. In addition, IMB processes are usually 50% cheaper than regular buildings in Indonesia.
For all permanent construction, a building permit is required (IMB in Indonesia). The legislation and procedure will differ for each individual location/area. It usually takes 2-3 months to get the building permit once all the drawings have been submitted.
Once the bamboo quotation is approved, we require a deposit of 40-50% of the total cost in order to prepare material and teams. The balance is divided in between the other parts of the bamboo building depending on the size of the project and work to be done.
Will have to be done by a general contractor and are at the charge of the client. The foundations will have to be sized regarding loads on bamboo structure supports and soil tests analysis.
When planned during the design, electric cables and sockets can be integrated in the bamboo columns. The electricity and plumbing have to be sized and installed by a professional to avoid any further damage in the integrity of the building.
