1. Efficiency & Stability

The shape of the geodesic dome allows for the creation of the largest possible volume and enclosed space with minimal building materials while ensuring maximum stability.

In other words: Achieving an even greater volume with less material while maintaining the same or higher stability is simply not possible. Especially in terms of height and the associated volume, a large enclosed living space can be created.

The cost-benefit ratio is therefore unbeatable.

2. Aesthetics & Well-being

A hemispherical dome integrates seamlessly into any environment. The height and volume create a wonderful sense of freedom. Shapes influence our well-being and should be considered in architecture and natural landscape planning. The GEODOME offers a more organic alternative to conventional right angles and rectangular structures.

3. Construction

The structure consists of an internal framework (steel and wood) and an outer shell (ETFE film), which are connected. The film protects the interior from rain and wind. At the same time, it creates a new living space where both the house and garden are covered by the GEODOME.

4. Ventilation / Cooling / Heating / Climate Regulation

The dome has a centrally located roof opening, which can be electronically opened by 40–60 cm, as well as four large double doors (optional gates). Additional underground pipe cooling is also possible.

As warm air rises and escapes through the roof opening, it automatically draws in fresh, cooler air through the open doors or underground pipes. Even with closed doors, there is no stagnant air, as there are no corners where air could accumulate. The free air circulation evenly distributes heat within the GEODOME space.

Thanks to wind protection, blinds can be installed outside the windows of the inner building, efficiently blocking sunlight in summer and preventing the interior from overheating. Clay, wood, and straw regulate humidity and temperature inside, creating a pleasant indoor climate. Once plants and trees are integrated into the dome, the system naturally regulates itself.

Electrical ventilation systems, air conditioning, and filters are not necessary and are not part of our concept.

Our goal is to be simple, cost-effective, efficient, low-maintenance, and durable!

Experiences from similar projects show that the climate zone inside the GEODOME remains consistently above the local climate. In Germany, for example, this means a Mediterranean climate year-round. Combined with a 400 m² floor area, this opens up numerous possibilities for self-sufficiency (permaculture). There is ample space, and creativity knows no bounds.

5. Light & Shade

A translucent outer shell combined with minimal construction materials ensures optimal use of natural light and solar energy for plants, people, and energy generation.

The film allows a large portion of radiation in the UV, visible, and IR spectrums to pass through. Large areas can be shaded cost-effectively using sun sails, or by printing specific areas of the film. Interior-mounted modules (photovoltaic/solar panels) can further contribute to shading and energy efficiency.

6. Acoustics & Soundproofing

Compared to glass, polycarbonate, or acrylic, ETFE surfaces significantly reduce echo inside the building. Sounds from outside the dome are softly muted within.

7. Stability

Geodesic domes are considered earthquake-proof. Their hemispherical shape also provides excellent aerodynamics, allowing them to withstand even high wind speeds with ease.

8. Self-Sufficiency

The GEODOME is ideal as an “autonomous bio-cell,” creating all the necessary conditions for self-sufficient living. The climate can be regulated, enabling the year-round cultivation of fruits, vegetables, herbs, and berries. Kiwi and grapevines can thrive along the multi-story house walls inside the dome.

• Water Storage: The large surface area of the dome’s shell allows for efficient rainwater collection. With proper storage tanks, one can go months without rainfall. In combination with a filter system, the collected water can be used as drinking water or for domestic use (irrigation, washing machine, etc.).

• Heat Efficiency: In winter, the exterior walls of buildings inside the dome cool down much more slowly, as they are no longer in direct contact with outside air. A compost system inside the dome can generate passive heat, as microbial decomposition reaches temperatures of 60–70°C.

• Energy Production:

  • Photovoltaic and solar modules inside the dome ensure a steady supply of electricity and hot water.
  • A hydrogen fuel cell system can generate enough hydrogen during summer to power the home throughout winter.

9. Quality of Life

High ceilings automatically create a sense of spaciousness, openness, and freedom. The tall dome also allows for generous interior ceiling heights of 2.70m–3m, making for comfortable living.

During winter, life inside the dome continues as usual. Plants, herbs, flowers, and trees contribute to well-being with their scents, shapes, and colors. Harvesting from one’s own indoor garden is a major advantage and fosters a personal connection with nature.

10. Advantages for the Inner Building

Cost savings on:

1. Roof structure (rafters, tiles, battens, gutters).
2. Windows (single or double glazing is sufficient).
3. Heating system and heating costs.
4. The GEODOME shell allows for thinner interior walls, reducing construction costs.

Additional benefits:

1. The top floor can always be used as a rooftop terrace.
2. A large winter garden enables year-round growth and self-sufficiency.
3. The absence of overhanging eaves allows more sunlight to enter the interior.
4. The entire house is structurally protected from weathering (windows, doors, facade).
5. Significantly fewer thermal bridges, leading to lower heating costs.

It is also entirely possible to first build the dome and then construct the inner house weather-independently—a significant advantage for construction workers.

Traditional heating and air conditioning systems are not planned for the inner house. Baseboard heaters combined with wood-clay-straw walls and ceilings provide comfortable indoor temperatures. With intelligent window placement, heating may not be necessary at all.
