A geodesic dome is a spherical structure made of triangular or polygonal facets that distribute the stress within the structure. It is a type of tensegrity architecture that uses tension and compression to create stability. Geodesic domes are efficient, lightweight, and durable and can be used for various purposes, such as housing, factories, observatories, or entertainment venues. The geodesic dome concept was first developed by Walther Bauersfeld, a German engineer, in the early 20th century. He used it to build a planetarium for the Carl Zeiss Optical Company; however, the term was coined by Buckminster Fuller, an American inventor and visionary who popularized and patented the design in the 1950s. He envisioned geodesic domes as a solution for the post-war housing crisis and a way to promote environmental awareness and social harmony. Geodesic domes have many advantages in terms of sustainability, materials, and costs. They can be constructed using renewable or recycled materials like bamboo, timber, or plastic. They also use less material and energy than conventional buildings and can withstand harsh weather conditions and natural disasters. Building a geodesic dome varies depending on the size, location, materials, and additional features, but it is generally cheaper than a traditional house. In the United States, average prices for geodesic domes typically range from $50,000 (45,500€, £43,500) to $500,000 (455,000€, £435,000), while in Europe, the average prices for geodesic domes typically range from $43,600 (40,000€, £34,800) to $436,000 (400,000€, £348,000).
What is a geodesic dome?
A geodesic dome is a spherical shell structure based on a geodesic polyhedron. It is a type of building characterized by a lattice-shell construction, where rigid elements called struts distribute the structural load throughout the dome. Geodesic domes are known for their strength-to-weight ratio, allowing them to withstand heavy loads despite their lightweight design.
