During this geodesic dome course we built a wooden dome on our home site with the intention to create a space for visitors and friends. The dome has a diameter of 4,3meters and a height of 3,65meters. We will cover this dome with yurt canvas and we are currently designing an elevated roof section for air circulation and are looking for windows and doors to add to the structure. We are planning for 4 south facing windows in the bottom part of the structure
Before starting the geodesic dome course we prepared the foundations and the floor. Making all the concrete blocks and the supporting beams level which did take us more time than we had expected. We also added some supporting beams between the main beams to better support the floor. The floor was constructed with tongue and groove. We used 22mm x 14cm x 250cm. We started working out from the middle after having made a centerpiece, which helped to hold all the beams in place. The supporting poles for the dome were put up on top of the finished floor. In our case they were 150cm long. In a future project we might make the poles a bit longer to allow for a second floor or a mezzanine in the dome.
Our geodesic dome course began with an introduction to geodesic domes and some of the options one can choose to build such a structure as well as information on where to find the necessary measurements and angles and materials. Next we went on to the practical part of preparing the wood and the metal connectors for the actual construction process. We used an angle grinder to clean the wood and but the metal connectors into 6cm long pieces. We used a chop saw to cut the required angles into the wood. Next we pre-drilled holes into the wood and did the same with the metal connectors. We could have done all of the work with battery run power tools but our generator did help us use multiple tools at the same time without having to be charging up batteries all day.
Once all the preparation work was completed we went on to put the dome together. Armed with 2 drills the work advanced quickly and we didn’t need longer than 2 hours to put the structure together. Lastly we hoisted the dome onto the existing structure of floor and poles and ended the workshop.
The next day we went out to the neighboring town to buy 7 x 9 meters of greenhouse plastic to protect the dome from rain and humidity. The wind however got under the plastic and lifted it off the dome. We therefore decided to cover the walls with some plastic tarp that we had on site. The dome is now wind and waterproof and we have started using it as a space for storing tools and wood but also as a greenhouse for the baby plants.
It doesn’t look very nice and even in February it gets extremely hot inside but this is just a temporary solution until we get the yurt canvas.
We are in the process of ordering the yurt canvas to cover the structure and we look forward to creating a space as cosy as our current yurt.
