Affordable steel modular housing, manufactured at scale, delivered where America needs it.

Steel in. Finished modules out. Set on site.

What ARQIX is

The product.

Volumetric steel modules on standardized chassis. Homes and apartments, from single-family to mid-rise, fully fitted out before they ship. Engineered once and repeated, which is what keeps them affordable.

The standard.

Every ARQIX module is built inside a state-recognized industrialized buildings program. Third-party inspectors from an Approved Testing Facility verify construction in the plant, before the module ever ships. Units carry the state insignia on arrival, engineered to the International Building Code and national fire and structural standards.

Platform

Partner factories build. ARQIX engineers, governs and delivers.

Two steel chassis, one kit of parts, and the deployment classes that set how each building is engineered.

The chassis logic

Two chassis carry every product.

The 13′ × 40′ chassis carries the compact home and the townhomes. The 13′ × 30′ chassis serves the two bedroom compact home and the multifamily line. Both are welded steel, 11′-0″ high, drawn from one structural schedule and one kit of parts.

Standardization is the affordability story, and it is structural rather than a number. The box is engineered once and repeated. The document set a reviewer sees on the second project is the one they saw on the first. Factory production runs in parallel with site work rather than after it, so the months a project spends under construction are fewer.

Deployment classes

Class L and Class H.

The building height sets the class. The class sets the sprinkler design, the rated assemblies and the protection the factory applies before the module ships.

Class L

Up to 4 stories

Single family homes, low-rise stacking, small-lot and garden apartments.

Designed to NFPA 13R sprinkler provisions
Designed to 1-hour rated assemblies

Class H

Over 4 to 10 stories

Mid-rise apartment buildings where high-rise code provisions apply.

Designed to IBC high-rise provisions
Designed to NFPA 13 sprinkler provisions
Designed to 2-hour rated assemblies
Fire-resistance protection applied as factory scope

Class descriptions are design intent at the platform level. Assemblies, ratings and package content are documented per project through the applicable state program.

Products

Three families. One platform.

Compact homes, townhomes and multifamily, all drawn from the same steel chassis and the same kit of parts. One kit, repeated, is what makes the product affordable to build at volume. Open a family to see its models, plans and renderings. Pricing is per project, on request.

Compact homes

A whole home in one or two modules.

Single storey, flat roof, delivered finished and set on a prepared pad in a day. The one bedroom is a single 13′ × 40′ module. The two bedroom mates two 13′ × 30′ modules side by side, wet cores back to back, so the home makes one utility connection.

One bedroom

520 SF · one 13′ × 40′ module · 1 bed, 1 bath

Two bedroom

780 SF · two 13′ × 30′ modules mated · 2 bed, 1 bath

Renderings are illustrative and do not depict delivered ARQIX projects.

Specification

The numbers.

Models	One bedroom, 520 SF. Two bedroom, 780 SF.
Modules	One 13′ × 40′ chassis, or two 13′ × 30′ chassis mated
Footprint	13′ × 40′, or 26′ × 30′
Module height	11′-0″
Program	1 bed, 1 bath or 2 bed, 1 bath. Standard bath program, with accessible options available.
Structure	Welded steel chassis. Noncombustible primary structure.

Site scope

What the site provides.

The module arrives finished: structure, envelope, mechanical, electrical and plumbing, fixtures and interior finishes installed under factory quality assurance. Foundation, utility connections and site finishes are site scope and are defined per project. The two bedroom adds a site roof kit spanning both modules.

Accessible layouts are designed for at the platform level. The requirements that apply to a given home are confirmed at the project level, with the local jurisdiction.

Priced per project.

ARQIX quotes a defined program on a defined site. There is no list price, because the site scope, the delivery distance and the unit count are what set the number.

Plans

Both models, laid out.

The one bedroom puts sleeping area, three-quarter bath, linear kitchen and living area inside a single 13′ × 40′ module. The two bedroom opens the mated pair into one living, dining and kitchen room, with two bedrooms, a full bath and a laundry and utility core on the other side.

One bedroom · 520 SF

Two bedroom · 780 SF

Plan views are illustrative. Layouts and finishes are confirmed at engineering release for each project.

Townhomes

Modules stacked, two and three high.

The same chassis stacked vertically and run in a row to the parcel. One, two and three bedroom models, each delivered finished, set and stitched on site. The three-high configuration is the governing structural case for the family.

One bedroom

Two storeys · upper balcony

Two bedroom

Two storeys · two stacked modules

Three bedroom

Three storeys · three stacked modules

Kitchens, baths, stairs, flooring and glazing are installed indoors, then inspected before the module leaves the floor.

Living, dining and kitchen

Taller buildings carry fire-resistance protection applied as factory scope, so the module arrives with the protection the building requires.

About

A manufacturer, built product first.

ARQIX Modular designs, engineers and delivers volumetric steel modular housing for the Eastern United States, from Washington, DC.

The thesis

Every serious attempt to industrialize housing has failed the same two ways, and usually together. The factory was built before the orders existed. And no one built a product: every job was a custom project, so the factory never became a production line.

ARQIX was formed around the opposite order. The product came first: two standardized steel chassis, one kit of parts, one quality system, drawn into a single platform standard. Production runs through established modular manufacturing partners under ARQIX-controlled documents and independent inspection. Capacity is added when demand documents say to, not before.

ARQIX is a manufacturer, not a developer. It makes affordable housing for the market that site-built construction serves least well, and it is delivered through the review structures that already exist: the state program for the module, the local jurisdiction for the site.
