Architecture
with a carbon receipt.
Sustainable Architectural Fabrication — Architecture with a carbon receipt.

Overview
Every project we make comes with a material passport: composition, embodied carbon, and end-of-life pathway. Our default materials draw on recycled aggregate, bio-composites and closed-loop polymers.
Engagement
- Scale
- All project sizes
- Lead time
- No added lead time
- Materials
- Recycled PETG · PLA-X · Cellulose bio-composite · Mycelium (R&D)
Capabilities
What we do.
- Recycled and bio-composite specification
- Embodied carbon accounting per project
- Closed-loop take-back program
- Low-waste additive-only fabrication
Deliverables
What you receive.
- Material passport per project
- Embodied carbon report
- End-of-life plan
Process
How this discipline is made.
Step 01
Baseline
We measure the embodied CO₂e of the conventional spec before proposing an alternative.
Step 02
Substitute
The material stream is replaced with a bio-composite or recycled polymer of equivalent performance.
Step 03
Passport
The finished project ships with a signed material passport and take-back plan.

Questions
Asked often.
- Do you have LEED / BREEAM documentation?
- Yes — we supply EPD-style documentation ready for sustainability consultants.
- What's the carbon delta vs. concrete?
- Typically 40 – 70% lower embodied CO₂e per m² depending on material choice.
- Can we specify recycled content only?
- Yes — we can commit to 100% post-consumer feedstock on request.
- What happens at end of life?
- We take the piece back into feedstock, or hand it to a certified regional recycler.
