OSA · A home without decades of debt is not a utopia. It is an engineering challenge.

Owning a home is not just about money. It is also about how we build. For centuries, we have favored rectangular boxes.
Earth provides the materials. The sun provides the energy.
Efficient geometry and open-source plans can reduce material use and costs.
The next step is to start building differently! With the help of Artificial Intelligence (AI) and newly developed digital tools, we can put this knowledge into practice.

The core of the problem

Conventional thinking says "affordable housing" is an unsolvable problem. But the question is asked backwards.

Why is owning a home so expensive? Several factors drive the cost: inflated land prices, often pushed higher by legal restrictions, bureaucracy with unnecessary permits and fees, middlemen extracting value at every step, and mortgages that turn home ownership into decades of debt repayment.

These are rules and systems created by humans, not laws of physics. With an engineering approach and open-source building plans, we can break that cycle.

The problem with boxes

A rectangular building is not always wrong. In crowded cities, it made efficient use of small plots, shared walls, and buildings placed side by side more practical. The problem arises when we treat that urban compromise as the only possible form of shelter.

The rectangular room, the square house, and the cubic apartment block are forms that became widespread because space was scarce. They became so familiar that we stopped questioning where they came from.

Yet the Earth is vast. Outside dense urban grids, we have open space, sunlight, and nature. Why build in the shape of urban constraint out in the open?

We build boxes because we have always built them. Not because they are always the best form.

The box
  • Sharp corners collect structural stress
  • Flat roofs fail under load
  • Maximum material for minimum strength
  • Poor thermal efficiency
  • High waste in construction
  • Expensive to build and maintain
  • Disconnected from natural forms
The dome
  • Stress distributed across entire structure
  • Strongest shape known to engineering
  • Minimum material for maximum strength
  • Superior thermal performance
  • Less waste, faster construction
  • Lower long-term cost
  • Found throughout nature

A geodesic dome encloses more volume per unit of surface area than any other structure. It distributes stress so evenly that it actually gets stronger under load. Buckminster Fuller understood this in the 1940s. The question is why we are still building boxes in 2026.

The shoulders we stand on

Fuller spent his life proving that “doing more with less” is not idealism but engineering. Fresco spent his life designing the cities and structures of a post-scarcity world. Both were ignored by mainstream architecture and housing industries. Both were right.

OSA was founded to continue their unfinished ideas. Using open-source approaches, sharing knowledge, and with the help of Artificial Intelligence (AI), it explores and presents overlooked building technologies that could contribute to realizing every person's basic right to a safe and accessible home.

How we get there

Not through political parties, not through street protests, not through the next election, left or right. We propose an “anarchist approach”. No passive submission to authority. It is time to build a new model that makes the current one obsolete.

01
Open designs, freely sharedEvery dome design, every Blender file, every calculation is published openly. No patents. No paywalls. The knowledge belongs to everyone.
02
Start with something small and prove feasibility.Let it be a dome for a kennel, an outdoor cat shelter, a greenhouse, or a workshop. Every small dome we build proves that the idea can be realized. What people see in practice often changes minds faster than arguments.
03
AI helps coordinate work and support decisions.These decisions once depended mainly on individuals in leadership positions. Leaders are not the problem. The problem arises when a system depends on one person’s knowledge, judgment, integrity, and personal taste. Parametric design, open-source software, and collected human knowledge are not replacements for human creativity. They are amplifiers. We use every available tool.
04
Open-source, portable, and system-agnosticOur open-source software and bootable systems are not tied to one type of computer or operating system. They have been tested on laptops, servers, and different hardware architectures. The capabilities of an average modern laptop often exceed those of yesterday’s most powerful server. This includes servers designed for edge computing. OSA supports the open-source operating systems FreeBSD and Linux, as well as hardware architectures including ARM and x86. Our designs work with local materials, local builders, and local conditions.
05
Reuse knowledge and materials. Build to last.We reuse materials instead of throwing them away. We build for a long service life. The plans stay open, so that those who come after us can improve them.

The right to repair

The right to repair is older than any regulation. A hundred years ago people built with wood, stone, and brick, and these houses still stand. When a roof leaked, they repaired it themselves.

No authority granted this knowledge. It passed from parents to neighbors, from hand to hand, for centuries. The modern system has largely pushed it out of everyday life.

This does not mean that safety regulations are unnecessary. It means that we must distinguish between rules that genuinely protect us and rules that primarily collect money.

The right to repair one's own home is not granted by any act. We carry it with us. We already demand this right for phones and tractors. A home deserves it just as much.

Two projects, one mission

Buckminster Fuller developed the geometric and structural language of geodesic domes. Jacque Fresco offered a vision of an automated, resource-balanced social system.

Fuller contributed the geometry. Fresco offered the vision. OSA adds open plans, local fabrication, and a digital assistant for people who want to build.

Today, OSA asks a practical question: how do we bring open plans, local fabrication, and modern digital tools directly to an individual builder or small community?

OSA — Geodesic Domes

Parametric 3D models built in Blender using geometry nodes. Freely downloadable .blend files. Start with a 9-metre dome.

The vision: open-source housing that scales from a small dome to a family dwelling. Superior strength, thermal efficiency, material efficiency, construction speed. Long-term: designs that can be built anywhere, by anyone, with local materials.

Clawdie — Digital Assistant

Clawdie is designed as a local digital assistant on this path, running on FreeBSD. It can assist in understanding blueprints, adapting parametric 3D models, comparing materials, and organizing construction.

Note: Structural and engineering calculations must always be verified by a qualified professional.

Join the transition

OSA has no membership, no fees, no application form. If you share these principles, you are already part of it. Build something. Share it. Make the box obsolete.

This server

osa.clawdie.si runs on FreeBSD 15, nginx, and Let's Encrypt. Entirely open source, self-hosted, zero corporate cloud dependency. It is itself a small act of what OSA means in practice.

Fork this idea. Improve it. Build on it. The manifesto is the starting point, not the destination.
