How to build a geodesic dome

So, you want to build a geodesic dome? Great decision! You’ve chosen one of the best house designs available. Not only will you gain equity in your home faster than any other design, with proper planning and detailing, you can also achieve the second highest strength-to-weight ratio in the construction world: not bad for a self-built home.

Geodesic domes were invented by Buckminster Fuller in the 1940s, and were originally made of triangles. That’s right, only triangles, not hexagons like most people think. The advantage of triangles is that they are much easier to assemble—all you need is a bunch of straight sticks, some paracord, and presto! You’ve got yourself a geodesic dome. Here’s how I build one myself.

How to build a geodesic dome

A geodesic dome is a type of structure that uses triangles to form the surface and has been around since the 1950s. The shape of the dome is created by connecting hexagons to pentagons, which are then connected to triangles. The result is a strong structure that can be used for shelter, such as an observatory or home. This article will explain how to build a geodesic dome out of card, board and 2x4s.

Step One – Make Your Plans

The first thing you need to do is make your plans for your geodesic dome. You can use a program like Autodesk 123D or SketchUp to design your own dome or you can use someone else’s plans as long as they are in either PDF or DWG format so that you can import them into CAD software for viewing purposes only. There are plenty of resources online where you can find free plans for building domes out of card, board and 2x4s. These plans will help you determine how large your dome will be when completed so that you don’t make any mistakes when cutting pieces out of cardboard or using them in other ways during construction phase later on down the roadCardboard Geodesic Dome : 7 Steps (with Pictures) - Instructables

How to Build a Geodesic Dome out of Cardboard, Board and 2x4s

You can make a geodesic dome out of cardboard, board and 2x4s. This is an easy project that doesn’t require any special tools or skills. All you need is some cardboard and wood, along with a few other basic supplies. Cardboard is typically used for packaging materials, but it makes an excellent material for constructing a geodesic dome because it’s strong and durable. The most common type of cardboard used for this purpose is corrugated board, which consists of several layers of cardboard glued together at right angles to form a sheet. Corrugated board can be purchased at most home improvement stores.

Step 1: Cut Your Cardboard into Squares

The first step in building your geodesic dome is cutting the corrugated cardboard into squares using a utility knife or box cutter blade. You’ll need 12 squares measuring 12 inches by 12 inches each (for a total of 144 square inches). Each square should be cut from one side only so that it has one flat side and one rounded side (or “corrugation”). If you’re using standard sized sheets of corrugated board, then each square should measure about 1/4

This is the easiest way to build a geodesic dome. It is based on the 2×4 Geodesic Dome plans by Robert Lang, an engineer who has been building domes for over 30 years.8 Reasons to Build a Geodesic Dome — Ginkgo Farms

How to Build a Geodesic Dome

The basic design consists of 2x4s arranged in a hexagon with 3/16″ plywood between them. The resulting shape is a truncated icosahedron – 20 equilateral triangles around the outside connected by 12 pentagons in the middle – with a triangular hole in each face.

A geodesic dome is a structure in which the shape is derived from a network of triangles, hexagons and pentagons. The triangles create a spherical surface and the pentagons provide a lot of strength to the structure.

Geodesic domes were developed by R. Buckminster Fuller (1895-1983) during World War II as a result of his interest in building inexpensive housing for soldiers. The geodesic dome is one of the most efficient structures for its total weight, because it uses material efficiently by distributing loads evenly throughout the entire structure.

The easiest way to build a geodesic dome is with cardboard or foam core board. It’s important that you use something that will not warp or buckle when wet or when exposed to sunlight over time. You can also use 2x4s or plywood if you want a sturdier version that will last longer than cardboard or foam core board.

You’ll need:

Cardboard/foam core board (1 sheet per person)

2x4s (for each person)

Scissors/knife/box cutter


This is a guide to building a geodesic dome from scratch, with instructions for the most common size (a 12-foot diameter) and an octagon as an example. The design shown here has a 2’x4′ door opening, but larger ones can be built by increasing the size of the panels used.

The first step is to choose the size of your dome. The plans below are for a 12-foot diameter dome with a 2’x4′ door opening. There are several ways to calculate the size of your dome:

The radius of your dome = 6 feet (2×3), so make sure you have at least 4′ between each seam when laying out your panels. If you want a bigger door, add 6 more inches per side; if you want more room inside the dome, add 6 more inches per side as well. For example, if your door is 18″ wide and you want more room inside the dome than outside it, then build an 18″ wide door (which will leave you with extra space on either side).
