Prefabricated and modular options are great ways to save money. They also offer many benefits (less waste, less mess and easy modifications later). This is one of the most economical building options that we have seen this year. It’s also known as a “domehouse” and can be constructed for as low as $3500.
Inflatable concrete is the construction method for these “binishells”. They inflate the pneumoform (a balloon), and then place steel bar around the balloon shape to provide structural reinforcement for the final structure. They then pour concrete on top of it and it hardens. This creates steel reinforced concrete in the form of the balloon. They can make all kinds of shapes, including bubble-shaped ones or round ones. Then they make these small residential-style dome homes.
Dr. Dante Bini, an architect, pioneered the inexpensive building method in 1964. His son, Nicolo, also developed the binishell method.
They use them for all kinds of purposes. Yes, they can be used for residential, commercial, resort, recreational, or educational purposes.
As you can see, the build time for these materials is short and easy. Not much labor, either. However, you will need to have some experience with rebar and be able to pour concrete. You will also need the special items, such as the balloon “pneumoform”, which can be re-used.
You can also remove concrete slabs when you are done using them. It is also an option for disaster relief housing. To see more of Binishell’s work, find them in the Building Homes and Living directory. These dome houses can be viewed in detail. There are also other options that may be available to enhance the idea.
