ANCIENT ROOTS,
MODERN OVENS.

INTRODUCING: Opus One

Mortarless. Modular. Made-to-Last.
A true retained-heat oven engineered for versatility, serviceability, and decades of use. U.S. Patent Pending.

The problem: We want amazing outdoor meals but . . .

We don't want a huge permanent commitment.

Traditional masonry retained-heat

  • Large project:
    Specialists, easy to mismanage
  • Permanent:
    Fixed layout and function
  • Cracks/maintenance:
    Inevitable with mortar
  • Sunken cost:
    Hard to recover on resale

We don't want the portable compromises.

Live-fire only metal ovens

  • Demanding to run:
    Constant tending
  • Limited range:
    Bread and roasts are hard
  • Small & slow:
    Tiny pies, long recovery
  • Durability:
    Components fail, deteriorate

You've done the research.
You know what real retained heat can do.
Retain the heat, skip the concrete.

Founder's NOTE

I'm Jim. I've spent 20 plus years making the most reliable VW engine swap system on the market. VW Vans and Alloy Ovens may seem like worlds apart, but as I like to joke they're almost the same thing: both are exterior sheet metal and internal combustion.

Outdoor cooking might be my favorite thing, and I wanted a real retained-heat wood oven without the scale and pricetag of a home addition. So I built what I couldn't find: a low-hassle, true retained-heat oven that can move with you. I'm ready to build yours.

Opus One: the modern brick oven

The culmination of 6 years of design and four generations of prototypes.

How we retain the heat

MORTARLESS MASS

Goldilocks-zone thermal performance with stamina and stability. Pay attention to your guests not your oven.

STAINLESS SHELL

The tight gaps, overlaps, and multi-layers of the stainless outer shell and cassette core manage flow instead of mortar. Result: true retained-heat efficiency of a mortared oven, minus the failure points.

INVITE-ONLY DEMOS

Small-group bake sessions and private virtual walk-throughs.

Six years. Four generations. Hundreds of hours of instrumented fires. We set out to preserve the soul of a brick oven and redesign everything that made it fragile and permanent.

THE FLUE

THE FLUE

Moving the flue further from the operator isn't just nice for not getting smoke in your face, it also has additional function. It allows better firebrand (ember) settleout, and provides room for catalyst inserts if needed to satisfy local regulations. Because we did it correctly, all this happens while not degrading the flow and draft, and without changing the traditional front vent location relative to the dome.

SOMETHING ABOUT COVID AVAILABILITY

SOMETHING ABOUT COVID AVAILABILITY

During covid lockdowns, brick was hard to get, and we had to switch suppliers. This is when the reality of "standard" bricks sizing, huge variation in size that the mason is responsible for working with became apparent. So we collected all the size variants we could find and designed the mortarless cassettes to accommodate the differences.

JOIN FOR EARLY DEMOS

Four generations of prototypes. Rear-service access. Brick-by-brick replacement. Interchangeable fuel modules.

FIELD TRIALS

Select chefs and trade partners are putting the oven through its paces. Their feedback shapes the final spec and is shared with our launch community.

TRADE FEEDBACK

Pilot sessions with installers and designers to refine spec language.

PERFORMANCE LOGS

Instrumented temperature profiles from soak through bake-down.

"A LEGACY PIECE, NOT A DISPOSABLE APPLIANCE"

Built to be repaired, not replaced. An outdoor centerpiece designed to serve for decades.

Alloy Oven Opus One — U.S. Patent Pending.

WHY ALLOY VS. TRADITIONAL BRICK OVENS

Patent-pending stainless rib-and-spar frame with replaceable brick cassettes. No mortar, no curing cycles, no vulnerability to over-firing or moisture. Fires reliably after rain or even flooding, without covers or special procedures.

  • MORTARLESS, MODULAR ARCHITECTURE.

    Mix brick densities and suppliers to balance heat-up speed with multi-hour retention. Optionally upgrade with space-age Pyrogel® insulation for unmatched thermal efficiency and safer exterior surfaces.

  • TUNABLE RETAINED-HEAT PERFORMANCE.

    Wood & gas by default, with door-module options for charcoal, pellet, and even electric. Swap or combine fuels to match weeknight convenience or all-day wood-fired sessions.

  • INTERCHANGEABLE FUEL SYSTEMS.

    Replace individual bricks or cassettes, not the oven. Modular construction and rear-door access reduce downtime and extend usable life for decades.

  • LIFETIME SERVICEABILITY.

    True retained-heat performance without permanent construction. Assemble with basic tools, then relocate without demolition, cranes, or contractors.

  • TRANSPORTABLE AUTHENTICITY.

    A front-origin duct flows over the dome to a rear insulated chimney, improving draft, settling embers, and keeping the outlet farther from the cook.

  • ENGINEERED EXHAUST PATH.

    Sleek stainless form and engineered weather resistance. Crafted to elevate outdoor kitchens while withstanding rodents, freezing temperatures, and the elements.

  • REFINED, WARM-INDUSTRIAL DESIGN.

    Traditional brick ovens reflect the limits of their era. Alloy preserves their authentic ratios and cooking performance, but applies modern engineering to deliver greater value, precision, and durability without the old constraints.

FAQ

Have a look at most frequently asked questions.

CAN I MOVE IT?
Yes. Assemble with basic tools; relocate without demolition or cranes.
IS THIS A “PIZZA ONLY” OVEN?
No. Pizza, bread, roasts, and bake-downs on stored heat are where it shines.
IS IT WEATHER-SAFE?
The engineered shell keeps the elements out; mortarless design makes it more reliable than the postman.
WHAT IF A BRICK CRACKS?
Swap the brick. That’s the point of the cassette system.
WHAT FUELS DOES IT SUPPORT?
Wood & gas first; modules for charcoal, pellet, and electric are in development.
HOW MUCH DOES IT WEIGH?
Depends on how you decide to tune your bricks, but up to 1 ton. Under 150 pounds without the bricks.
