The shape of a space changes how the people inside it feel, think and behave. Most
buildings are designed the other way round: the shape is whatever the construction method
leaves behind. We wanted to start from the shape and work outwards, and see whether a
building designed that way could still be practical to make.
The dome geometry isn't a style choice. It's what happens when the volume you want to be
inside comes first and the structure is asked to serve it.
Whether that works is a question the built domes answer. They stand at Tsitsikamma and
Rosemary Hill: designed, engineered and built by us, on ground conventional construction
finds difficult, and lived in through real seasons.
Simple parts, interlocked.
The kit is a finite family of panels, joints and openings. No component is more important than another, none is redundant, and the same set assembles into every model in the range. Load travels through the geometry, so nothing extra has to be added to hold the structure up. That is the same logic nature uses, and the reason a dome can be light enough to sit on ground a conventional build can't economically reach.
That's what makes remote work possible. Lightweight components, a small crew, light equipment: mountain sites, conservation corridors, deep forest. Weeks on site instead of months.
Designed and engineered in-house.
GeoModular (Pty) Ltd was founded in 2025 by Steven Joubert, an electrical engineer who leads the design, and Vian Chinner.
We hold our own CAD and engineering files, so the design work, the structural detail and the build sequence sit in one place. We work as design-and-licence partners or as turnkey developers, depending on what a project needs.
