History & revisions
Track every change from sketch to field modification.
Humanity's next frontier isn't another planet.
It's finishing this one.
The open platform for construction knowledge — explore, adapt, and share the projects that shape the built world.
Open building knowledge
Explore open projects with full revision history.
Build together
Every plan gets history, contributors, issues, and a changelog.
Track every change from sketch to field modification.
Collaborate in the open — with attribution.
Surface problems and document releases.
The ecosystem
Static downloads stop when you download. Colemus compounds.
Find a project in the open knowledge base.
Create a local variant for climate, codes, materials, and budget.
Move from documented knowledge to site, with professional review when required.
Document field notes, open items, and release notes for the next builder.
Learn from others
Browse by building type.
Single-family, ADU, and compact dwelling projects with revision history.
Build locally
Adapt projects for climate, codes, materials, and budget.
Track jurisdiction-specific notes, permit paths, and community-documented compliance discussions — not guaranteed approval.
Hot/dry, cold/humid, coastal, alpine — fork variants with documented envelope and structural adjustments.
Regional material swaps with open BOMs and supplier notes from builders who've been there.
Cost-scoped variants with community comments on value engineering and trade-offs.
AI-assisted adaptation is on the roadmap — never a substitute for professional review.
Professional layer
Open knowledge stays open. Connect to licensed professionals when permits or stamps require it.
Why it matters
Every great civilization built upon the knowledge of the one before it. Colemus exists to accelerate that process.
Affordable housing pressure demands reusable knowledge, not reinvented drawings.
Construction expertise is trapped in local silos. Colemus makes it findable, adaptable, and improvable.
Platform vision
Open projects today. Smarter adaptation and permitting connections next.
