The Fornidos manufacturing center at Gateway South in St. Louis, with the Gateway Arch behind it — Gateway South, St. Louis · Coming fall 2027

Our homes start in our factory.

Fornidos is the first major manufacturing tenant at Gateway South, with a planned 55,000 sq ft plant just south of the Arch. Production is starting now in temporary facilities in Hazelwood.

Every panel is built indoors, to the same standard, then shipped flat to the job site.

As seen in

We don't build homes. We make them buildable.

Our panel system was evaluated once by the International Code Council, so it can be built in city after city. You choose the plan. Your crew builds it. It permits, inspects and finances like any other house.

Four panels. Every home.

Every Fornidos home is built from four ICC-ES evaluated panel types, made in the factory and shipped flat, ready to set with standard equipment and a local crew.

Fornidos floor panels framed with engineered I-joists

Floor Panels

Floor panels make up the foundation of each home. Each panel arrives framed, insulated and decked, ready to set on piers, footings or a basement.

Three types of framing: engineered I-joist, 2x10 lumber or Cold-Formed Steel
Insulation installed at the factory
All wood pressure-treated
Designed to meet the International Residential Code

Exterior Wall Panels

The weather-tight envelope of the home. Exterior walls close in the house, finished inside and out before they leave the factory.

4" or 6" walls, 8 or 9 ft tall
Lumber or Cold-Formed Steel framing
Energy efficient, insulated to meet or exceed code for your climate
Energy-efficient vinyl windows and doors installed
Siding outside, drywall inside

Interior Wall Panels

Every room, framed and finished in the factory. Interior walls arrive with drywall installed, ready for paint and trim.

Drywall installed and ready to finish
Pre-hung interior doors included
Walls lock into the layout in hours, not days
Lumber or Cold-Formed Steel framing
Built-in chases (open channels in the walls) so your licensed local trades can run wiring, plumbing and ductwork, and local inspectors can check it

Roof Panels

The roof sets in sections, closing the home in fast against the weather.

Trusses, insulation and roof decking in one panel
Drywall ceiling installed
Engineered for wind, snow and seismic loads across most of the country

Energy efficiency, built in.

Designed to help builders deliver higher energy efficiency, with the insulation and air sealing done before the panels ship.

R-15 + R-6Walls, with continuous insulation

Evaluated once. Ready for plan review.

Two independent reports from the International Code Council Evaluation Service (ICC-ES) are why a Fornidos home can be permitted like any other new house.

ESR-5284

The panels are evaluated.

An ICC-ES Evaluation Report on the wall, floor and roof panels, under the 2024, 2021 and 2018 IBC and IRC. It publishes what each panel can carry, so a building official can look it up instead of re-checking every panel.

EER-5284

The whole house is evaluated.

An Equivalency Evaluation Report under the residential code for one- and two-story houses built from those panels, inside its engineered envelopes. Every Fornidos plan is drawn inside one.
