What is Aircrete?

the revolutionary material

Aircrete is a lightweight, insulating cement mix made by blending cement with foam. It’s affordable, easy to shape, and ideal for building strong, beautiful, energy-smart domes and structures.

  • Lightweight, insulating walls — easy to cut, carve, and finish
  • Resource-friendly — uses less cement per volume than dense concrete
  • Beginner-friendly methods with step-by-step training to guide you
  • Compatible with reinforced, engineer-approved designs

Aircrete opens the door to a new way of living: walls that are fire- and pest-resistant, sculptable into organic shapes, and built to last.

Why Choose Aircrete?

Strong & Sustainable

Combined with the Domegaia method, aircrete structures are fire-resistant and earthquake-resistant — all while using less material than traditional building styles.

Energy‑Smart

Aircrete’s cellular structure creates natural insulation, helping interiors stay cool in hot climates and warm in cooler ones — reducing energy use and increasing comfort year-round.

Design Freedom

Curve it, carve it, and create — from arched doorways to round windows, niches, and skylights, Aircrete adapts to your imagination, giving you freedom to shape unique spaces.

Cost-Efficient

Made from widely available materials, Aircrete keeps building simple and affordable. With our tools and training, you save on labor while learning to build smarter, lasting structures.

Beginner Friendly

With step-by-step courses, architectural plans, and digital or on-site coaching, anyone can build successfully with confidence.

Accessible Anywhere

Aircrete can be made almost anywhere in the world. We provide the education, tools, and professional services to help you succeed from start to finish.

Higher ROI

Resistant to pests, fire, and mold, Aircrete structures require less upkeep than traditional buildings — saving money on maintenance and lasting for generations.

Frequently Asked Questions

How do I know which services I need?

You don't need to figure it out alone. Just fill out our Project Inquiry Form or book a free 15-minute Discovery Call. We'll guide you through what support fits your project best.

Can I purchase each service separately?

Yes—but we bundle services based on your project’s scale and needs, since most builds require more than one area of support. You don’t have to commit to everything upfront—you can start small and add more as your project evolves.

Can you help if I already have architectural plans?

Yes! We can review and adapt your existing plans to suit Aircrete construction. We’ll help you avoid common pitfalls and ensure your plans are ready to build.

How much does it cost?

Pricing depends on the scope and complexity of your project. We offer starting ranges for each service tier, and once we understand your goals, we’ll provide a clear estimate. No surprises.

What’s included in a custom design package?

Each design package is unique to your need but can include custom floor plans, 3D visuals, dome-to-dome triangulation drawings, layout planning, and suggestions for plumbing, electrical, and passive cooling.

How long does the process take?

Timelines vary by service and project scale. Small design projects can be completed in 3–4 weeks; larger projects may involve multi-phase timelines. We’ll map it all out clearly with you.

Can you help me with permitting if I live outside USA?

Yes. We assist with local code research, zoning insights, and referrals to local engineers or architects as needed. We’ll help you get the paperwork right.

Can I work with my own builder or team?

Absolutely. Our role is to set you up for success, whether you're DIY-ing or working with a local team. We can also help you find vetted builders if needed.

Do you offer support during construction?

Yes. We provide consulting and project management options throughout the build. That can include progress reviews, and remote support.

We’re the global leaders in Aircrete dome building—with decades of experience, engineer-backed methods, and a community of builders in over 30 countries. We don’t just sell plans—we guide you through a full process designed for real-world success.
