Star Portal (Rhombic Dodecahedron)

The Star Portal design by Gregg Fleishman is a rhombic dodecahedron shape, made with no metal or fasteners, held up by feet and contains an inner floor for meditation.

Gregg has dedicated nearly three decades to studying the rhombic dodecahedron. This polyhedron, closely linked to the cube, comprises a central cube and extensions into adjacent cubes, forming two cubes by volume. The extensions are pyramidal with faces inclined at 45 degrees, resulting in coplanar diamond faces.

These diamonds have a width-to-length aspect ratio of one to the square root of two. This ratio not only defines the diamond faces but also the dihedral angles of related cubic polyhedra, also known as "The Lost Triangle of Pythagoras"

The rhombic dodecahedron is a fascinating geometric shape that has garnered attention in various fields, including architecture. This polyhedron consists of twelve rhombic faces, and its unique properties make it a compelling choice for a meditation chamber, having energetic and aesthetic potential, along with infinite structural applications.

One of the most notable characteristics of the rhombic dodecahedron is its ability to tessellate three-dimensional space. This means that multiple rhombic dodecahedra can fit together without any gaps, which can be advantageous in creating efficient and aesthetically pleasing structures. The tessellation property allows architects to explore innovative designs that maximize space while maintaining structural integrity.

In terms of structural efficiency, the rhombic dodecahedron exhibits a high degree of strength relative to its weight. This is due to its symmetrical nature and the distribution of forces across its faces. Research indicates that polyhedral structures, including the rhombic dodecahedron, can withstand significant loads while minimizing material usage, potentially leading to cost savings in construction.

Furthermore, the rhombic dodecahedron's geometric properties can enhance the aesthetic appeal of a building. Its unique shape can create visually striking facades and interior spaces, contributing to a building's overall character. Architects have increasingly incorporated such geometric forms into their designs to create iconic structures that stand out in urban environments.

In addition to its aesthetic and structural advantages, the rhombic dodecahedron can also facilitate natural light distribution within a space. The arrangement of its faces allows for innovative window placements, which can enhance the interior environment by maximizing daylight penetration. Studies have shown that well-lit spaces can improve occupant well-being and productivity, making this geometric form not only a design choice but also a functional one.

The rhombic dodecahedron presents a multitude of opportunities for architects and designers. Its ability to tessellate, structural efficiency, aesthetic potential, and capacity for natural light distribution make it a valuable geometric form in contemporary architecture. As the field continues to evolve, the integration of such unique shapes will likely play a significant role in shaping the future of architectural design.
