Eco-Home Mob Build At Boulder Mountain Guest Ranch, 2017


In June of 2015 Marcin Jakubowski, founding partner of Open Source Ecology (OSE), came to boulder Mountain Guest ranch to demonstrate how to operate one of his co-collaborative inventions, an earth brick press machine. We purchased the Compressed Earth Brick Press (CED) for many reasons…for the materials it produced, how sustainably it produced the end materials, and the intention of the machine.

“The CED Compressed earth blocks have many advantages as a building material: by making theuntitlfffed building materials from the readily available dirt on the building site, they eliminate the need to transport bricks from elsewhere, reducing financial cost and environmental impact. CED’s are very strong and insulate well against both heat and sound, making for very energy-efficient building. Best of all, the material they use is already on-site and does not need to be and can be purchased — quite literally, dirt-cheap!” opensourceecogolgy.org

The CED takes a simple concept of using clay/silt/sand to make bricks by tightly compressing the materials…and wha-la! The simplicity of the CED is just one many advantages including price, around $9,000. The CED can make up to 5,000 bricks in an 8 hour period.

fffffSo what do you do with one of these machines if you are a private owner able to produce that many bricks in one day…share! Create an open source in communities for information and material resources.

BMGR has many of the same principles as Open Source Ecology. Learning of the similarities has been a heart-warming, confirmation that it takes a compassion to build community.

Open Source Ecology “derived their organization’s name from a concept which refers to the integration of the natural, societal, and industrial ecologies- Open Source Ecology- aiming at sustainable and regenerative economics. Convinced that a possibility of a quality life exists, where human needs are guaranteed to the world’s entire population- as long as we ask ourselves basic questions on what societal structures and productive activities are truly appropriate to meeting human needs for all. At the end of the day, the goal is to liberate our time to engage in exactly that which each of us wants to be doing- instead of what we need to do to survive. All have the potential to thrive. Today, an increasingly smaller percentage of the world’s population is in this position.fffffff

It was inspirational and an honor to host Marcin, such a brilliant and compassionate person and to know that his and OSE’s intention is to use their resources to give back, contribute, create a positive change. Principles we also endear.

Eco-Expandlable Home Mob Build:

In fall of 2017 Boulder Mountain Guest ranch will host a 5-day workshop. a “Mob-build” for a modular seed-home (the core of an expandable home) loaded with ecological features.

This workshop is intended for everyone who is interested in exploring the rapid building of environmentally-friendly homes (no previous building experience required). Blending modular wood panels with Compressed Earth Block construction. The goal is to demonstrate that quality housing can be built with multi-purpose flexibility using module-based designs and parallel building for optimizing design evolution. Our goal is reducing the duration of construction by a factor of 20 compared to industry standards, at ⅓ the cost of conventional housing. This design process involves a rapid parallel swarm workflow with a large team using simple-to-follow documentation created with Agile and Waterfall methods prior to build.

  • Making and installing a hydronic heating system (open source stove with pellet burner, control panel, and in-floor heating)
  • Making and installing a thermoelectric generator(experimental, version 0.1)
  • Making a super-efficient refrigerator with open source electronics
  • Designing and making a rooftop rain water collection system (w/ first flush diverter and rainwater cistern)
  • Making a water filtration system(experimental, version 0.1)
  • Making a biogas digester (experimental, version 0.1)
  • Building and installing modular plumbing panels(experimental, version 0.1)


Why? A Beneficial Paradigm Shift:

Human housing is not a luxury it is a basic need, one that on a global level could be increasingly supplied with ease and efficiency and most importantly within the process of regenerative construction. The countless collaborators upon whose shoulders this Vision stands – imagine a world of innovation accelerated by open, collaborative development – to solve wicked problems – before they are created. We see a world of prosperity that doesn’t leave anyone behind. We see a world of interdisciplinary, synergistic systems thinking – not the isolated silos of today’s world.  but a means for humans themselves to evolve. The creation of a new world depends on expansion of human consciousness and personal evolution – as individuals tap their autonomy, mastery, and purpose – to Build Themselves – and to become responsible for the world around them. One outcome is a world beyond artificial material scarcity – where no longer do material constraints and resource conflicts dictate most of human interactions – personal and political. OSE seeks to provide tools that in theory would help remediate material resource conflicts and deficits on both global and local levels.


untitleggdMarcin Jakubowski – Marcin was trained as a fusion physicist. He left academia right after finishing his Ph.D. to start a farm – in Missouri. For the last 7 years, he has been working on the Global Village Construction Set – a set of enabling tools and machines for building regenerative infrastructures. Marcin is passionate about creating the Open Source Economy – a new operating system for Earth. See Marcin’s bio.
