Most of the time, I design geodesic structures in AutoCAD. To streamline the process, I use an Excel-based script that exports the grid directly into the active drawing, with precise pipe rotation alignment relative to the connector node axis. The script was developed by a good friend, who generously shared it with me.

This particular frame uses a custom connector of my own design — more details on that will be shared in a future post.

The resulting structure features a carefully optimized configuration:

• 7 distinct types of struts, each tailored to its specific geometric role within the dome.
• 4 unique connector hub types, designed to accommodate varying angular demands at different grid intersections.
• A dedicated doorway assembly, integrated into the dome’s curvature to maintain structural integrity without compromising accessibility.

The base row is fully uniform and assembled using a single type of strut, greatly simplifying logistics and installation while enhancing stability and aesthetics.

This configuration balances manufacturing efficiency with design precision — ideal for glamping applications that require both durability and visual impact.

Now it’s time to focus on the shell. The material selected is a high-performance Blackout PFH membrane manufactured in France — known for its durability and UV resistance, ideal for glamping structures.

Seam allowances have been precisely planned at 25 mm, positioned along the lower left side of each panel, following the "direction of water flow" principle. This ensures reliable waterproofing and simplifies the welding process.

The final pattern layout was carefully optimized to match the dome’s geometry and outdoor performance requirements.

Interior Draping of the Geodesic Dome

Designing the dome's interior requires a different production approach — fabrication through sewing. The textile layout includes an inward offset slightly greater than the radius of the structural struts. This ensures proper clearance and avoids tension at the contact points.

• Seam allowances are set at 20 mm, distributed evenly around the perimeter of each fabric segment.
• The selected material is heavy-duty Oxford nylon with a single-side PVC coating, weighing approximately 480 g/m², offering strong durability and waterproofing.
• The fabric is secured at the structure's node points, using threaded rivets pre-installed in the hubs.
• Along the perimeter, I use standard hook-and-loop tape (Velcro) of 50 mm and 25 mm width, enabling easy assembly and maintenance.

This draping solution provides a comfortable and refined interior space while maintaining the dome’s geometric fidelity.

Additional Interior Unit Inside the Dome

In addition to the shell and structural elements, the project includes a compact multifunctional cabin built into the dome’s interior. This custom module features:

• A bathroom with shower, offering full essential comfort.
• A small kitchen area, suitable for cooking and food storage.
• A dedicated storage closet, for organizing belongings or equipment.
• An additional sleeping space above the cabin, designed for two guests — perfect for families or group stays.

This interior module is conceived as a self-contained unit and will be covered in detail in a future update.

For now, here are a few images from the test assembly before delivery to the client.

Building such a structure is more than a technical challenge — it’s a journey through engineering exploration, creative problem-solving, and strategic design thinking. Every element of the dome, from geodesic calculations to the integration of interior modules, demands meticulous attention and a balance between aesthetic vision, durability, and utility.

Despite its complexity, the process is profoundly rewarding. Ideas come to life in tangible form — evolving from sketches to a fully realized space ready to welcome guests.

On the economic side, geodesic frames are among the fastest-returning structural solutions for glamping and ecotourism. Their energy efficiency, ease of transport, and quick assembly make them ideal for launching commercial ventures with swift and impactful ROI.

We all are living under the dome.
