Domes - The Sustainable homes of the future


Our company Biodomes designs and builds custom, one of a kind glass and metal geodesic domes. We offer over 20 different models that can be sized and customized in a number of ways. The brand new technology we use enables us to offer the highest quality domes, from both the structural and aesthetical point of view. Our company uses only the best high end materials like steel or aluminum alloys and laminated security glass that can be single, double or triple glazed. Our goal is to create structures whose function is as important as their form, buildings that are beautiful and functional at the same time.

Earth sheltered, glass geodesic domes represent the ultimate sustainable eco home of the future and the timeless design and alluring aesthetics of geodesic domes offer unsurpassed versatility, from the ultimate sustainable eco home to a futuristic geodesic glasshouse; from a visitor attraction piece to a recreational space; from an indoor pool to a stellar observatory; from a classroom to a science lab - the possibilities are endless. 

Aside from their natural beauty, domes also have many structural advantages. Geodesic shelters have been built around the world in varied climates and have proven to be the strongest and most efficient human shelter ever conceived.

Geodesic domes are extremely strong for their weight due to their omni triangulated surface that provides an inherently stable structure, with a natural resistance to external factors like earthquakes up to 8.5 on the Richter scale, winds up to 320 km/h due to the aerodynamic shape and loads up to 20 tones per point of structure.

The picture gallery above presents the Pollux dome model, it is our first dome built that was designed as a greenhouse for exotic plants in a temperate climate. It has a diameter of 5 meters and a height of 2.5 meters above ground and a total height of almost 5m due to its below ground interior. All features are custom made, done to customer specifications, starting from the round door that provides excellent ventilation during summer, the stone walls that act as thermal mass during winter, the magnetic shades that protect from the summer heat and the round grass steps that provide a very comfortable and green entrance.

Geodesic domes utilize the power of natural geometry to make incredibly efficient structures. Geodesic domes are three-dimensional structures using stable triangles approximating spheres to create multiple load carrying paths from point of load to point of support. Triangles are the strongest shape because they have fixed angles and don’t distort very easily. The triangle is the only arrangement of structural members that is stable within itself without requiring additional connections at the intersection points to prevent warping of the geometry. In other words, apply pressure to one edge of a triangle, and that force is evenly distributed to the other two sides, which then transmit pressure to adjacent triangles. That cascading distribution of pressure is how geodesic domes efficiently distribute stress along the entire structure.

The spherical design results in highly efficient and effective air circulation in both summer and winter. Less surface area makes these buildings less susceptible to temperature changes, and thus, inexpensive to heat and cool as compared to rectangular homes. The aerodynamic exterior means that cold and warm air flows around the structure instead of forcing its way into the interior.  They mirror the suns path thus maximizing solar gain all day, all year and they also distribute perfectly heat and sounds.

There are two reasons domes are energy efficient. The ambient airflow inside the dome is continuous, with no stagnant corners, requiring less energy to circulate air and maintain even temperatures. The energy required to heat and cool a dome is approximately 30% less than a conventional building. The second is the high volume-to-surface-area ratio, requiring less building materials to enclose more space. The lower the ratio of a building’s outside perimeter to its enclosed living area, the less energy is required for building, heating and cooling. The sphere has 25% less surface area per volume enclosed than any other shape. The dome combines the inherent stability of triangles with the advantageous volume-to-surface-area ratio of a sphere. The larger the dome, the more efficient it becomes. This is demonstrated by doubling the diameter, which encloses eight times the volume. 


 We offer over 20 different geodesic models and each can be made in different sizes, varying form 6 meters (area of 28m2) to over 20m diameter that has a 320m2 square meter interior. Our company uses only the best high end materials like steel or aluminum alloys and laminated security glass that can be single, double or triple glazed. All the domes that we build require a foundation and are non-movable structures that can't be sold in a kit format. Our company handles every aspect of the design and construction process in order to offer a turn-key dome/house. We also build earth sheltered domes like in the image above, as well as the newest dome models that have hexagons instead of triangles. 
We are based in Carei, Romania, and can build anywhere in the European Union.
