The special houses are tailored to perfectly rest on their foundation, carefully set in the earth’s natural contour, so that they have minimal impact on the environment. We create to scale structural models made of hand whittled bamboo sticks instead of blueprints. These models are redone in 3D line in computer programs for our engineers to study and confirm that the building adheres to our strict codes.

completion to ensure structural integrity and longevity. Bamboo like any natural fiber, has to be protected from the sun as well as the rain. The over hanging roof and tilting structural columns are designed to take care and protect the villas for the long term. To prevent humidity that will create moisture, our structural beams are secured by steel and concrete to a large river rock stones. These are in turn secured within the earth’s foundation by steel rods reaching down several meters, as it is determined by our team of structural engineers.

Why does our company use bamboo as one of the main material in building; because of its strength, beauty, and flexibility. Another reason we use the magnificent bamboo is because it has a four year growth cycle and contains carbon sequestration capacity. It is the most environmentally conscientious building material conceivable. In a world of retro fitting or redesigning traditional items and materials to be slightly less ‘bad’, we
decided to be unique and to wipe the slate clean and start fresh. Though bamboo has traditionally been used throughout Asia in short term structures, new treatment methods have given it a capacity to live a longer life. Our engineers, architects and designers have created a completely new vocabulary. Not only is bamboo good for the environment, it also helps the people living in that space connect to nature which then enhances quality of life.

— There are 1,500 species of bamboo that can be found in Asia, Australia, North and South America and Sub-Saharan Africa.
— Bamboo’s tensile strength is 28,000 pounds per square inch versus 23,000 pounds per square inch for steel.
— The fastest growing plant on the planet, it grows at 2 inches an hour and can be grown in damaged soil
— One clump can produce 200 poles in just three to five years.
— Bamboo can release 35% more oxygen than equivalent stands of trees. — Some bamboo even sequester up to 12 tons of carbon dioxide in the atmosphere. — Bamboo can also lower light intensity and protects against ultraviolet rays.
— The largest species of bamboo can reach 130 feet in height. — Some species of bamboo develop flowers after 65 or 120 years.
Strength
With the compressive force of concrete and the strength to weight ratio of steel.
Renewability
With very little attention, a bamboo shoot can become a structural column within three years, and that building could stand strong for a lifetime.
Sustainablility
With its three year growth cycle and carbon sequestration, it is a uniquely efficient and responsible resource. Even sustainable timber can’t begin to compare with bamboo as a conscientious building material.
Long Life
Though bamboo has traditionally been used throughout Asia, new treatment methods have given it a longer lifespan. Our company choosen bamboo, selectively harvested from local sources, is treated ecologically, then lab tested to confirm its durability and integrity.

Q U E S T I O N S
hat kind of bamboo is used to build your houses and where does it come from? ‘Petung’, Dendrocalamus Asper, which comes from Bali and Java. It grows in small clumps along the river valley, usually on privately owned land, so we purchase our bamboo from hundreds of individual farmers. How much bamboo is required to build an average-sized villa at Green Village? Our 300sqm houses at Green Village Bali contain +8100 running meters of bamboo structure or approximately 1200 poles. An additional +3000m is used in interior finishing. Does bamboo lose its form after a while? Bamboo is a flexible and tensile material with the strength equivalent to steel. We account for the flexibility in the engineering process and work to ensure bamboo is maintained.
Is it easy to access a large quantities of bamboo trees? Yes, bamboo is plentiful in river valleys in Asia, and the clumps regenerate each year. Bamboo is ready for use as a building material at age three to five years. What are the new treatment methods that can give bamboo a longer life? Our main treatment uses a boron solution that suppresses the glucose inside the bamboo and renders it inedible for insects. Does it include the use of chemicals, or is the bamboo treated naturally? The bamboo is treated naturally with boron, a chemical element found in nature. It is only slightly more toxic than table salt and it is safe to use in a family home. What is the life span of bamboo? Structural performance of our structures based on our engineers’ calculations is a minimum of twenty five years. If the bamboo is chosen well, treated properly, designed carefully and maintained, it can last a lifetime.

How well does the bamboo survive in the sun and rain? Our houses are designed and built to avoid prolonged sun and rain exposure. It is also coated with a weather resistant coating. What kind of maintenance is required in the long run? Properly treated and selected, mature bamboo in a well-designed structure does not require significant structural maintenance. The bamboo should only be treated once, before construction begins; additional treatments against insects are not necessary. The roof of a bamboo house must be maintained to protect the columns from prolonged rain contact and direct sun exposure; poles that are exposed should be monitored and protected and joints reviewed every few years to confirm they remain secure. Recoating both structural and interior bamboo every two to four years will improve its appearance and longevity, and we anticipate that the quality of and technology behind coatings will advance over time, including waterproofing and UV resistance. Has the company done any Life Cycle Analysis on the bamboo products? We work with testing labs in Jakarta and Singapore. Test results confirm our bamboo density and treatment absorption.

ur bamboo is carefully selected from the river valleys and mountains of the islands of Bali and Java in Indonesia. It takes just a few months for a new bamboo shoot to reach its full height, and in three years it becomes timber ready for harvest.
Harvest
We harvest from clumps that, once established, grow a new generation of shoots each year. Our company takes great care to ensure that only the mature poles are harvested, creating an incentive for the bamboo farmers to allow the younger shoots to grow to maturity for subsequent years’ harvests.
Treatment
In the past bamboo buildings were susceptible to termites and Powder Post Beetle infestations that would eat the bamboo to dust. Our bamboo is treated with a boron solution, an naturally salt solution that renders the bamboo indigestible to insects. It has a toxicity level just 1.5 times greater than that of regular table salt. The solution is reused in a closed loop system ensuring minimal impact on the ecosystem.
Design
Our design process occurs on the land and for the land. The houses are tailored to gently rest on their foundation, carefully set in the earth’s natural contour, so that they have minimal impact on the environment. Instead of blueprints, we create to scale structural models made of hand whittled bamboo sticks. These models are replicated in 3D line in computer programs for our engineers to study and confirm that the building adheres to our codes. Our architects and engineers then follow the project in depth through completion to ensure structural integrity and longevity. The dramatic overhanging roof and tilting structural columns are designed to protect the villas for the long term. To prevent moisture, our structural beams are secured by steel and concrete to large river stones. These are in turn secured within the earth’s foundation by steel rods reaching down several meters, as determined by our team of structural engineers.

n an initial conversation we’ll define design and build requirements with you including space, site, size, location and any key features such as landscaping, material palettes, while estimating budget and timing. This conversation can happen onsite, in person at our office or email.
Masterplanning
Our master planning reveals opportunities for landowners, which may not have been considered. This is an inherent part of our process which helps our clients realise the potential of their site, prioritising permaculture and landscape aspects of the process.
Concept Design
We prefer to design on the land, for the land. We consider every aspect, from the flow of the wind over the site, to the angles of the sun throughout the day and how they’ll interplay with each space. We interpret the clients each area of the home, how they like to move through a space. We design a flow from room to room that connects with the most
inspiring structural forms, that fit with the land. We construct temporary platforms and walkways across the site, wherever possible, building a satellite design office to work from, and later tracing the shape of roofs with light weight bamboo frame works, drawing in the air. We develop the design at 1:100 or 1:50 scale by making a bamboo sketch model using sticks of bamboo to capture the form. It continues with the land and landowner until we capture the fullest.
Design Development
As we develop the concept into a detailed design we finalize all technical and construction aspects, preparing a Tender Package for construction. The bamboo structural blueprint is delivered as a 1:100 or 1:50 scale model where bamboo sticks represent each column, beam and bundle, each scaled with diameters corresponding to the desired bamboo type and supplemented with detailed drawings. Our interior architectural design and custom furnishings are integral to the structural design and are developed

in parallel. Costings and logistics are analyzed, and we coordinate with consultants, where needed, for key expertise. Our company is well versed in designing and building with bamboo in climates similar around the broader of Southeast Asia, construction in cooler climates will require further consultation.
Contract Documentation
We collate contracts with vendors providing other aspects including the development including landscaping, additional interior features, furniture, pool and other complementary vendor items.

Construction on Site
Once all planning is finalised and agreed upon, construction commences with our skilled bamboo builders and craftsmen from PT Bamboo Pure. Our architects and designers follow up with site inspections and coordinate with clients for site visits as needed. For construction outside Bali, we will ascertain early on if there is a bamboo industry or skilled trades people in the region, or harvestable bamboo and treatment facilities and plan accordingly.

SHARMA SPRINGS RESIDENCE Sharma Springs is the tallest bamboo structure built in Bali. The main building has six levels, four bedrooms, a spacious living room with an excellent view, and a 15 meter long tunnel entrance. The structure is supported by a central tower, which holds a smaller inner tower. The inner tower is the secret to its majestic height. The design was inspired by the petals of the lotus flower. Each room has a different theme based on the desires of the client. The property also includes: an entry building, a guest house, a storage cave, a riverside yoga pavilion, an outdoor spa and a poolside barbecue all surrounded by beautiful permaculture gardens. Sharma Springs was designed for the
Sharma family as a jungle fantasy escape. It is a 6-level, 4-bedroom 750 sqm home overlooking the Ayung river valley, built almost entirely of bamboo. The entry to the house is via a dramatic tunnel-bridge that brings you directly to the open air living, dining, and kitchen spaces on the 4th level. The staircases circle around the central tower to the levels below: kids play room, as well as four bedrooms and a library that each enclose for air conditioning with full length spinning glass windows. The sixth floor look out has sunset views over the Ayung river valley and Green Village. Master metal smiths custom built the shower stalls, stone carvers from Java carved boulders into counter slabs. Our team also custom designed each item of the furniture for this house.

Set within a rural landscape along Bali’s ayung River, Green Village is a planned community based on design concepts and sustainable established by the artisans and craftsmen that built Green School. All homes here are designed and built entirely from bamboo around the natural contours of each plot and feature rare riverfront locations as well as elevated plats featuring views of the Green School and Bali’s volcanoes. Building the houses does not entail any destruction of the surrounding rainforest and no dug foundations or retaining walls are needed, making the housing project especially low impact on the environment. The multi floor structures rest on bamboo poles anchored into the rock of the river bank. The sides of the houses have been left open thereby merging the interiors with the natural surroundings and allowing a gentle breeze to flow through them, keeping
the internal temperature down. Homeowners play a significant role in custom designing their houses to suit their lifestyles. One of the customized villas, for example , features design accents and finishes created as a result of collaborative efforts between the client and the design team. These include naturally black bamboo flooring , hand-hammered copper bath fixtures, custom pieces from Ibuku’s home furnishings line and a lagoon shaped swimming pool set against the backdrop of the coconut grove and river below. Each house measures around 3,230 sqft and contains around 26,000 ft of bamboo or approximately 1,200 poles. An additional 9,800 ft is used in interior finishes.

AURA HOUSE The land along the ridge at Green Village has always been a place we have looked forward to designing. It has unique terraced contour, a shady forest with a sense of mystery, and protected river views. Each of the three sites speaks to us differently. The third and final of the sites at Green Village feels like you’re in a Pleistocene forest, in a grove of giant black palms. Just two bedrooms, Aura is like a fallen star or a little golden jewel built of the purest blonde bamboo and woven the way a bird would.
