What is a geodesic dome house? History, Benefits, and More

Geodesic dome houses are spherical structures based on geodesic polyhedrons. In mathematical language, a geodesic is the shortest path between two points that never moves sideways, while a polyhedron is a 3-D shape with a flat outward face surface. Why make a house in this shape?

The structure's interlocking triangles make it durable and futuristic. Instead of using curved surfaces, it is a series of interconnected lines that form a curved shape. The design of geodesic domes is based on Architect Buckminster Fuller’s idea of doing more with less. He applied his technological knowledge to ensure the dome was comfortable and energy-efficient.

This article explores its history from ancient times to its modern revival. We will discuss the pros and cons of these structures, the factors to consider before building, and how to build dome homes.

History of Geodesic domes

Dome Structures in Ancient Times 

Early dome structures include dome-shaped huts made from reeds, saplings, and red clay. The Innuit people in the Arctic also built igloos from ice blocks. Like cob houses, these structures were present in ancient times, specifically in the Middle East, India, and the Mediterranean.

However, older humans didn’t refer to them as geodesic domes because the term was formed in the modern century, the 1920s. Natural space and domes were typical in the Roman Pantheon. 

Romans built large-scale masonry hemispheres that required heavy wall supports. This concept also extended to Byzantine Architecture, the Constantinople building style. Byzantine builders developed a method to raise geodesic domes on piers, allowing lighting and communication from four directions.

They used inverted triangular masses of stones curved vertically and horizontally. The structure's highest point rested on four piers, and the joined sides formed arches over the openings of the four faces of the cube. The bases of the structure also met in a circle, forming the foundation of the dome. 

A prominent dome building in Greece is the Pantheon. It is a large dome supported by walls of cylindrical columns. The Pantheon unites Roman and Greek architectural styles. It has an opening at the top of the structure that serves as the primary light source. The oculus also reduces the dome's weight on the foundation.

Dome architecture went out of style from the 12th to the 16th century because of Gothic architecture. However, it regained its popularity during the Baroque and Renaissance periods. Furthermore, humans reimagined dome architecture in the 20th century by inventing geodesic dome homes.

The Growing Popularity of Geodesic Dome Homes in America

Walter Bauerfeld, chief engineer of Carl Zeiss Optical Company, designed the first geodesic dome after World War I. He built a geodesic dome planetarium for his planetarium projector, but it wasn’t called a geodesic dome then. He designed a 16-meter polyhedron with 20 faces with 3,500 metal rods and wood.

In July 1926, The Wonder of Jena, a geodesic dome larger than the planetarium, opened to the public. As mentioned earlier, we didn’t call the structure a geodesic dome until around 1948, when Buckminster Fuller created the term geodesic from his field experiments with Kenneth Snelson, an artist at Black Mountain College.

The legacy of Richard Buckminster Fuller

Richard Buckminster Fuller is another pivotal figure who contributed to the popularity of geodesic dome structures. He was an architect, cosmologist, engineer, inventor, and mathematician who focused on solving housing problems by recreating nature’s coordinate system in all spheres, from molecules to planets.

He lectured the world on the efficiency of geodesic domes. Understanding nature’s own coordinate system meant he understood that gravitational forces aren’t linear. They are spherical. Richard developed the geodesic dome in 1947 and built the first practical application of the geodesic dome home in 1953. He patented it in 1954.

In 1959, he moved into a geodesic dome house near Southern Illinois University and lectured at Inglemoor High School in 1970. He also lectured at the University of Washington in 1972, the First Congregational Church in 1979, and Shoreline Community College in 1980. 

In 1977, he developed the Fly’s Eye Dome and the Pinecone Dome. Because his designs were better than all the architectural structures around the time, Buckminster Fuller received the Bucky Gold Award from the American Institute of Architects. He also published books like Domebook 1 and 2 and workshops that taught people the construction process of a dome structure.

Today, his legacy lives on through the Buckminster Fuller Institute, which continues to innovate to solve global issues from shelters to climate change.

Benefits of Geodesic Dome Homes

• Geodesic dome builders use few materials during construction, making it easy to move around. 
• They don’t use concrete for construction. Instead, they use glass, wood, metal, and polycarbonate building materials to build the geometric components of geodesic domes. These building materials are easy to lift, ensuring the easy assembling of your home at your desired location. Natural Spaces Domes, a geodesic dome-building company, has patented connection hardware for easier installation.
• According to Pacific Dome, another company, the separate parts of their dome house are packed in a box truck. It shows just how easy transportation is during construction compared to other structures.
• Instead of cold air hitting a flat wall, the dome shape has a concave interior that creates natural airflow. It also acts like a headlight reflector that reflects interior heat, preventing radiant heat loss. Overall, it saves heat and reduces energy costs spent on air conditioning.
• They provide natural light. The light comes in through their panels, saving electricity until nighttime. 
• Unlike traditional homes, it efficiently improves the relationship between indoor spaces and nature. Geodesic domes are great for gardens, an art studio, or a music room.  
• It uses a few materials to create a living space with less surface area. Dome homes have no corners, making more room for activities. 
• Geodesic domes require low maintenance because they are made from durable materials that can withstand outdoor weather like heavy snow, high winds, and rainfall. They are suitable for people who live in areas with high winds because they can withstand wear. You can also clean geodesic homes made with glass and polycarbonate materials by wiping them with water, mild detergent, or power washing. 
• Some geodesic dome home builders use bioceramics to construct these domes, which makes them fire-resistant. A geodesic dome home is an excellent housing option for people who live in areas regularly ravaged by wildfires.
• Another benefit of geodesic homes is their versatility. You can use them as shelters for living, work, and studio space. Uses for geodesic domes also include weather observatories, glamping tents, retreats and community spaces, and children’s playrooms. You can customize dome homes to suit your needs and taste. 
• You can also deconstruct geodesic dome homes quickly and transport them to another space. 
• Their aesthetically pleasing features are another plus. 

Cons of Geodesic Dome Homes

While geodesic domes have incredible benefits, they also have disadvantages. Constructing a dome home can cost a lot because they are unique structures that are less common than conventional building structures. So, the construction labor will cost you. 

Another thing that might cost you money and energy is getting building permits. Depending on the location of your land, you might need them. Some areas have strict building codes and regulations that make it challenging to build unique structures.  

Also, installing some features we enjoy in traditional homes in dome homes can be challenging. An example is chimney installation. It is difficult to include chimneys and fireplaces. Installing fire escapes in larger domes will also cost a lot.

Furthermore, because of its spherical shape and panels, rooms and divisions within a dome home are not easily created. It will be difficult for you to get off-the-shelf fitting materials because most of the materials in the market are for right angles for traditional homes with square and linear structures.

Dome owners might also encounter leaking problems if the builders don’t install them properly. Sometimes, people install domes themselves without adequate knowledge or employ the services of an unskilled dome builder. 

Factors To Consider When Building A Geodesic Home

According to Shelter Structures, a specialist company in mobile and modular space solutions, here are some things to consider before building geodesic domes: 

1. Consider the purpose and diameter of your dome house before buying a geodesic dome kit. Domes above 20 meters are great for large-scale social gatherings, events, and art exhibitions, while 10-20 meter domes work best for small concerts, outdoor weddings, and corporate events. Geodesic domes below 10 meters are suitable for greenhouses, Airbnbs, hotels, campgrounds, and workspaces. 
2. Your budget is crucial as it determines dome homes' size, design, and quality. Geodesic domes below 10 m are more affordable for those with limited budgets.
3. You must also use high-quality materials like PVC, polycarbonate, and pre-drilled frame tubes. Ensure that everything is labeled correctly and that you have all you need. You'll need tools like thick ropes, a tape measure, a step ladder, electric and adjustable wrenches, and a utility knife. You'll also need a hammer drill if the structure is on a concrete foundation.
4. Consider the local building regulations and permits you might need. There are varying zoning laws and building codes that can affect your construction. Ensure you have all necessary permits to avoid unnecessary stress.

How do you build geodesic homes?

The frame structure of geodesic domes is one of the most crucial parts of the structure. The dome’s structure is self-supporting with interconnected triangles, which form a series of hexagons, reducing the materials used. 

Connect the various parts of the structure with bolts, nuts, zip ties, and special connectors. Use bolts and nuts for larger domes. Some structures already come with pre-cut holes to help you join them accurately. Zip ties work well for small geodesic domes, especially if they are temporary structures.

After setting up the structure, the next step is to add openings for windows and doors. You must plan these fittings properly because fitting them into a spherical structure can be challenging. 

Consider ventilation, natural light, and the dome layout before marking the locations of the windows and doors with chalk or tape. Along the markings, create openings for doors and windows. Some geodesic kits come with a pre-drilled door, which makes fittings easier.   

Let's not forget the covering for your dome. You can use many covering materials, including PVC (polyvinyl chloride), polycarbonate panels, tarpaulin, and canvas. Canvas has good insulation, breathability, and water resistance qualities, while tarpaulin is UV-resistant, waterproof, and lightweight.

Tarpaulin is excellent for temporary domes, but polycarbonate panels are more suitable for permanence. They are lightweight, durable, and resistant to UV rays. PVC covers can also withstand harsh weather conditions and ultraviolet rays. However, you'll need to sew it together to make it leak-free. 

You need to consider how to attach the covering to the structure securely. Thread cords or doors through the turkeys on the edges of your covering. You can use straps and buckles to allow flexibility to tighten and loosen the covering as needed. You can also use clips to grip the covering to the spherical structure. However, they are only suitable for temporary use.

Conclusion 

Geodesic homes have unmatched energy efficiency and can still withstand heavy snows, winds, and storms. Given their futuristic aesthetics, believing they were developed about 100 years ago is challenging. 

A dome house makes adequate use of the available space. Most dome home builders use PVC, polycarbonate panels, glass, and canvas to build domes. Some use concrete, which makes concrete domes much more expensive. If you want to be one of the dome people, consult expert builders to construct your dream home.
