A house in harmony with nature is much more than a house; it is a continuation of the spirit of nature within us.

Houses for a new quality of life

GEON is always striving for sustainable solutions to common problems. This is especially true when it comes to affordable housing construction with a focus on quality of life. Natural building materials grow in many regions of the world, like Africa. Harvesting these raw materials and processing them to innovative building materials not only leaves a positive ecological footprint. I creates valuable local jobs and strengthens local economies. And the best part is that houses built with these natural materials provide a much healthier living environment with for a higher quality of life.

GEON has developed a remarkable sustainable housing concept with a negative CO2 footprint using hempcrete and bamboo.


Bamboo exhibits remarkable properties that make it ideal as a structural construction material. Its very strong fiber imparts bamboo with a compressive strength twice that of concrete and a tensile strength close to that of steel. The high sheer stress of bamboo means it can be bent without breaking.

Bamboo is a member of the grass family with a high tolerance for marginal land and is among the fastest-growing plants in the world. Some species can grow nearly one meter per a day!

Advantages of Bamboo as a Building Material

  • Tensile strength: Bamboo has higher tensile strength than steel because its fibers run axially.
  • Fire Resistance: Capability of bamboo to resist fire is very high. The presence of significant amounts of silicate acid and water, allow it to withstand temperatures of up to 4000 °C.
  • Elasticity: Bamboo is a preferred material in regions prone to earthquakes activity due to its elastic features.
  • Weight: Bamboos is a very light material, making handling, transportation and construction easier.
  • Safe: Bamboo is a non-toxic organic material that poses no danger to health

When implemented correctly, these natural materials are cost effective and easy to use while imparting many desirable properties to the final built-up structures. This has the potential to transform the construction process as it is sustainable with a negative CO2 footprint.


The sustainable, eco-friendly alternative to traditional building materials like concrete or clay bricks.

Hempcrete is an entirely natural composite made by mixing lime and hemp in proportions adapted to the task at hand. It may also include small amounts of sands, pozzolands or cement to shorten curing times. Hempcrete is a highly versatile material and among the best performing, non-toxic, ecological and renewable materials available. Unlike steel and concrete, it has a negative carbon footprint. Hempcrete absorbs up to 165 kg of carbon per cubic meter during manufacture.

Hempcrete is an excellent insulator and moisture regulator, and pulls CO2 from the air and emits oxygen, helping with indoor air quality. It is non-toxic and resistant to mold, insects and fire. Hempcrete is energy efficient and even has a higher thermal resistance than concrete. The material also has excellent acoustic attenuation properties.

Hempcrete is very versatile in its application. It can be cast to bricks or formed to hempboard, but can also be cast in situ or sprayed. It can be used to build insulating walls, as well as for linings, screeds and renders.
