What is the maximum dome size?
The maximum diameter will depend on the type of dome you are building.
Domestar F1: Ideal up to 4m with posts of approximately 2.04m, but possible up to approximately 5m in diameter, meaning posts of approximately 257cm.
Domestar F2: Approximately 6.60m in diameter, meaning posts of approximately 174 and 198cm.
Domestar F3 (all models): Ideal for diameters under 8m (uprights of approximately 159, 155 and 133cm) but possible up to 10m (uprights of approximately 200, 196 and 168cm)
Domestar F4: suitable for domes between 6m and 12m in diameter. Ideal for around 9–10m in diameter.
What is the difference between a 3V dome and a 3V Kruschke?
The main difference is that the ‘classic’ 3V dome is not a flat-bottomed dome, whereas the Kruschke 3V calculation formula allows for a flat-bottomed dome.
Similarities:
Both models require:
- the same number of Domestar connectors (but these are NOT the same connectors)
- the same number of wooden struts and screws
- roughly the same total amount/length of timber for a given diameter and height (a difference of a few centimetres: compare using our calculators)
Although the assembly process will differ for the two models (the instructions are different), the difficulty of assembly will be the same. With the 3V Kruschke models, you just need to take great care to ensure one type of connector is correctly oriented.
Differences:
- the flat base for the 3V Kruschke model
- For the 3V Classic dome, you only need 3 different lengths of uprights, whereas for the 3V Kruschke you need 4 different lengths. The cuts are no more difficult; there are just 4 measurements instead of 3.
- For the Kruschke 3V model, care must be taken with the orientation of the Domestar 6A connectors.
Is there a ‘Kruschke’ version of the 2V model?
The 2V model always has a flat base as it is exactly a half-sphere. So there is no specific Kruschke model as it always has a flat base.
The “problem” with the 3V models is that they are cut into 3/7 or 5/7 sections (or 4/9 and 5/9 according to the literature), which is always less than or more than half a sphere, hence the flat base/non-flat base issue.
Building a Giant Dome Aviary: Which Domestar Kit to Choose?
Do you dream of a majestic space for your birds? The geodesic dome is the ideal structure for an aviary: exceptional weather resistance, unrivalled flying space and an aesthetic that enhances your garden.
But when faced with our range of Domestar connectors, one question often arises: which kit is best suited to my project? Here is our comprehensive guide to help you make the right choice.
1. Understanding ‘Frequency’: The secret to the shape
Before choosing your connectors, you need to understand two key concepts: Frequency (V) and Division (1/2, 3/8, 5/8).
Frequency (V1, V2, V3, V4)
The higher the frequency, the more triangles the dome has.
-
A V1 dome resembles a faceted crystal (few struts).
-
A V4 dome is almost a perfect sphere (many short ribs). The larger the dome, the more advisable it is to increase the frequency to maintain a solid and aesthetically pleasing structure.
The Layout: What height for what diameter?
This is where you determine the profile of your aviary. For the same ground diameter, the height will vary:
-
1/2 dome: This is an exact half-sphere. The height is equal to half the diameter.
-
3/8 dome: The dome is ‘flatter’, ideal if you have height restrictions.
-
5/8 dome: The dome is “slender”, exceeding the half-sphere. This is the preferred choice for aviaries as it offers immense vertical space for the birds to fly.
2. Which Domestar model for which aviary size?
Here is a comparison to help you choose based on the scale of your project:
🟢 Domestar V1: The small aviary or dome shelter
-
Ideal diameter: Up to 4m (posts approx. 2.04m).
-
Maximum: Up to 5m possible (uprights approx. 2.57m).
-
Why choose it? Quick and easy to assemble with just 11 connectors.
🔵 Domestar V2: The perfect balance
-
Standard diameter: Approximately 6.60m (posts of ~1.74m and 1.98m).
-
Why choose it? It’s the ultimate versatile size for a spacious garden.
🟠 Domestar V3 (All models): For large spaces
-
Ideal diameter: Under 8m (poles from ~1.33m to 1.59m).
-
Maximum: Up to 10m (poles from ~1.68m to 2.00m).
-
Why choose it? The V3 offers a magnificent curve. Note that we offer Kruschke (Base Plate) options for a perfect finish at ground level.
🔴 Domestar V4: The monumental aviary
-
Diameter: Between 6m and 12m.
-
Ideal: Around 9–10m.
-
Why choose it? With 91 connectors, it is the most robust structure and the closest to a perfect circle. Ideal for bird parks or enthusiasts.
In summary: Which kit for my aviary?
-
Want some height? Go for a 5/8 model (available in V3).
-
Do you want a simple dome? The V1 and V2 are your best options.
-
Are you aiming for a structure with a diameter of 8–10m? The V4 or V3 5/8 are best suited to support the weight of the mesh.
Expert tip: The larger your aviary, the greater the weight of the mesh and the wind load. Don’t hesitate to opt for a higher frequency (V3 or V4) to increase the number of fixing points for your netting or mesh!
And above all, don’t neglect the ground anchors!
