BOXABL expands offerings with ‘kit-of-parts’ modular platform

BOXABL is moving beyond its flagship Casita accessory dwelling unit with a Phase 2 product lineup that uses three standardized modules to configure more than 20 different home and apartment types, the company announced Tuesday.

The Las Vegas-based modular manufacturer launched a beta online catalog and configurator on its developer webpage that shows how the same core “boxes” can be combined into ADUs, single-family homes, estates, townhomes, garden apartments up to three stories, HUD-code homes, ranch plans and workforce housing.

The tool is an early version, but it marks a shift in BOXABL’s strategy from a single pre-set unit to a system intended to compete with conventional site-built housing across multiple price points and product types.

From one Casita to a full system

Phase 1 of BOXABL centered on the 361-square-foot Casita studio unit, which is factory-built, shipped folded and installed on site in under an hour, according to the company. The company has also announced the 120-square-foot “Baby Box” built to RV code for no-foundation setups.

Phase 2 applies the same manufacturing approach to a broader catalog. BOXABL said its R&D has focused on using just three standardized box sizes to generate the most common residential configurations and architectural styles. Those modules are combined on a structural grid to create:

• ADUs: studios to two-bed units for rental, multigenerational or flex space
• Single-family homes: floor plans aimed at the largest share of the market, including a 2,400-square-foot detached home highlighted in the catalog
• Townhomes: attached and standalone configurations oriented for light and privacy
• Garden apartments: multifamily buildings up to three stories
• Estates and ranch homes: larger and single-level plans targeting move-up and aging-in-place buyers
• HUD housing and workforce housing: manufactured and community-scale options

The firm said all products are designed around steel construction, 10-foot ceilings and factory-installed finishes, including appliances, large windows and tall doors. Units are manufactured in a controlled environment and shipped for on-site installation.

Why this matters 

For builders, BOXABL’s Phase 2 move is less about a single ADU product and more about a potential building platform. The company’s pitch is that by standardizing a limited set of modules, it can offer:

• Repeatable assemblies across product lines. The same boxes can be used in entry-level SFR, build-to-rent townhomes, small multifamily and ADU infill, which could simplify design, procurement and training for builders that work across multiple asset classes.
• Factory-controlled timelines. Off-site steel construction is positioned to reduce weather delays and quality variability, which may appeal in markets facing labor shortages and tight schedules.
• Permitting flexibility. Because the catalog spans HUD-code, workforce and conventional residential categories, developers may be able to match modules to different regulatory paths, though approvals will vary by jurisdiction.</li>

Housing professionals are watching whether industrialized construction can materially reduce build times and hard costs at scale. BOXABL is positioning its system as a way to unlock volume production through standardization, similar to auto manufacturing, while still offering multiple plan options to buyers and communities.

Early-stage platform, regulatory caveats

The Phase 2 catalog is described as a “beta” tool, with floor plans, configurations and finishes set to be updated and expanded as the platform develops.

The company also cautioned that commercial availability of Phase 2 products depends on regulatory approvals, manufacturing readiness and other conditions detailed in its SEC filings. That means timelines, pricing and delivery capacity are still variables for builders or developers considering the system for near-term projects.

The announcement comes as BOXABL pursues a merger with FG Merger II Corp., a special purpose acquisition company. The SPAC deal, if completed, would provide additional capital for scaling manufacturing and product development. Transaction details are outlined in filings with the Securities and Exchange Commission.

For now, the new catalog serves primarily as a signal to builders and land developers that the company intends to be a broader housing systems provider, not just an ADU maker. The next test for the platform will be real-world projects that can validate cost, cycle time and code compliance at scale.
