What do Elon Musk and prefab homes have in common? For now at least, a prefab house called Boxabl is Musk’s abode, which, rumor has it, he lives in near SpaceX ground zero in Boca Chica, Texas after selling off nearly all of his real estate holdings.
The 20x20 small prefab home might be commonly known as an accessory dwelling unit (ADU) or perhaps a guest house, but in the Boxabl world, it’s referred to as Casita. Unlike other small prefab houses, Boxabls have a unique, flat-pack design that allows them to break down to 8.5 feet in width and be delivered onsite via truck, train, air or ship.
The main materials in the prefab home are steel, concrete and EPS foam, specifically chosen for their durability. They don’t degrade like other building materials, so the structures are built to last a lifetime. Not only are Boxabls rated for hurricane-strength winds, but because there isn’t any wood or sheetrock that could be damaged by water, the prefab homes won’t grow mold or deteriorate due to moisture from floods.
In addition, the company said, “Nothing is fireproof. But Boxabl was engineered with fire resistance in mind. The interior and exterior of the structure is clad with non-combustible materials. We think this means flying embers that spread forest fires won’t ignite your Boxabl.”
There are several costs involved in getting a Boxabl set up, including the Casita itself, starting around $50,000. From there, you’ll need land, a foundation and utilities to plug into. You’ll also pay a delivery fee, but the company can hook you up with certified builders to unfold the Boxable for you in your desired location, which takes less than a day. However, the building will save you money in the long run, because it is extremely energy-efficient. Each tiny home relies on a small air conditioning system as needed and has high R value insulation, a tight building envelope and limited thermal bridging to keep the space fairly temperature controlled.
The small prefab home comes wired and plumbed, so it’s ready to accept solar power or any other energy source the buyer chooses. The prefabricated design, complete with nearly everything you need to open the door and move in (including a full-size refrigerator, stove, dishwasher and washer/dryer) is also seen as an option for temporary shelters that can be preloaded with supplies and delivered quickly for emergency response. Currently, there are no customization options, and the company is only taking orders while it completes a manufacturing plant.

Inside the Casita: The Compact Modular Home Redefining Modern Living
The term casita traditionally evokes a small, self-contained dwelling—often modest in scale, but rich in purpose. In the contemporary modular housing landscape, however, the Casita has taken on a distinctly high-tech meaning. Popularized by Boxabl and widely discussed after reports that Elon Musk resides in one, the Casita represents a new generation of ultra-efficient, factory-built living.
Boxabl’s Casita is the company’s flagship model: a fully prefabricated studio-sized home designed to deliver maximum functionality within a minimal footprint. More than a compact shelter, it is conceived as a complete, high-performance residence that arrives nearly finished and ready to live in.
One of the most compelling aspects of the Casita is how much functionality it delivers within a tightly controlled footprint. To better understand how space and systems are allocated, the table below outlines the core interior zones and their primary features, highlighting the efficiency-driven logic behind the layout.
| Area | Key Features | Design Purpose |
|---|---|---|
| Kitchen | Refrigerator, oven, microwave, dishwasher, dual sinks, cabinetry, integrated dining table | Full-service cooking and dining without sacrificing floor space |
| Living Area | Space for sofa and coffee table, adjacent to media center | Flexible social zone that can be reconfigured with bedroom layout |
| Bedroom | Separated by media unit, adaptable orientation | Privacy within an open-plan footprint |
| Bathroom | Shower and bath, sink, countertop, backlit mirror, sliding door | Space-efficient hygiene and comfort with residential-grade finishes |
| Utility Zone | Washer, dryer, ironing space, HVAC controls | Consolidated daily functions for streamlined living |
Together, these elements illustrate how the Casita prioritizes thoughtful zoning over sheer size—demonstrating that modular living is less about downsizing expectations and more about designing with intent.
A Fully Equipped Interior in a Compact Frame
Despite its small scale, the Casita is laid out with the logic of a much larger apartment. The kitchen is fully outfitted, featuring a refrigerator, oven, microwave, dishwasher, dual sinks, built-in cabinetry, and a dining table that seamlessly connects with the countertops. The result is a space that feels integrated rather than compressed.
Opposite the kitchen sits the bedroom, with the entry door acting as a subtle spatial divider. A built-in media center provides an additional layer of flexibility, allowing the bedroom to be visually or functionally separated from the living area, which accommodates a couch and coffee table. The configuration is adaptable, with the option to flip the living and sleeping zones as needed.
Smart Use of Space and Comfort
Adjacent to the kitchen, the bathroom continues the theme of efficiency without sacrifice. It includes a shower and bath, sink with countertop, a backlit mirror, and a sliding door that conserves space while maintaining privacy.
Elsewhere in the Casita, everyday necessities are thoughtfully integrated: an on-site washer and dryer, a designated ironing area, and centralized temperature control. With ceiling heights reaching approximately 9.2 feet (2.8 metres), the interior avoids the cramped feeling often associated with small dwellings, instead offering a sense of openness and light.
Built Differently, Built to Last
Unlike conventional homes constructed with timber framing, nails, and on-site assembly, Casitas are manufactured using a combination of steel, concrete, foam insulation, and laminated panel systems. This industrial approach results in a structure engineered for resilience.
According to Boxabl, the Casita is designed to withstand hurricane-force winds, resist mold, and tolerate flooding and heavy snow loads—performance benchmarks rarely associated with homes of this size. The materials and construction methods prioritize durability and long-term efficiency alongside speed of delivery.
Factory-Finished, Site-Ready
One of the Casita’s defining features is the extent of its factory completion. Electrical systems, plumbing, and HVAC are all installed before the unit leaves the manufacturing facility. When it arrives on site, the home is unfolded, secured to its foundation, and connected to utilities—dramatically reducing construction time and on-site labor.
In an era marked by housing shortages, rising construction costs, and a growing appetite for flexible living, the Casita offers a glimpse of what modular housing can achieve: compact, efficient homes that challenge traditional assumptions about how—and how quickly—we can build.
Frequently Asked Questions About the Boxabl Casita
What exactly is the Boxabl Casita?
The Boxabl Casita is a factory-built, modular studio home measuring roughly 375 square feet. It arrives folded for transport and unfolds on-site into a complete, code-compliant dwelling with a kitchen, bathroom, and living/sleeping area.
Is the Boxabl Casita considered a tiny home?
While similar in size to many tiny homes, the Casita differs in that it is built to modular housing standards rather than recreational vehicle (RV) codes. This distinction often makes it easier to permit as an accessory dwelling unit (ADU) or permanent structure, depending on local regulations.
Can the floor plan be customized?
The Casita’s floor plan is standardized to support mass production and quality control. Structural changes are not typically available, but owners can personalize finishes, furniture, and interior styling to suit their preferences.
How comfortable is the Casita for full-time living?
For individuals or couples who value efficiency and minimalism, the Casita can function comfortably as a full-time residence. High ceilings, full-size appliances, and a proper bathroom help it feel more like a compact apartment than a temporary shelter.
What utilities does the Casita require?
The Casita connects to standard residential utilities, including electricity, water, sewer (or septic), and internet. Requirements vary by site, and preparation of utility hookups is typically handled before delivery.
Does the Casita need a foundation?
In most permanent installations, the Casita is placed on a prepared foundation such as a slab or piers. Foundation requirements depend on local building codes and zoning regulations.
How energy efficient is the Boxabl Casita?
The Casita is designed with insulated walls, roof, and floor assemblies to meet modern energy standards. Its compact size naturally reduces heating and cooling loads compared to conventional homes.
Can the Casita be moved after installation?
Yes, the Casita is technically relocatable. While it can be moved, doing so requires professional handling and coordination, especially if utilities and foundations are involved.
Is the Casita suitable for families?
The single-room floor plan is best suited for one or two occupants. Families typically require additional bedrooms and storage, which the Casita is not designed to provide.
How does the Casita fit into long-term housing strategies?
The Casita is often used as an ADU, guest house, rental unit, or transitional housing solution. Its standardized design and rapid deployment make it appealing for addressing housing shortages and expanding residential density without large-scale construction.
The Boxabl Casita Floor Plan: Compact Living Reimagined
In an era defined by housing shortages, rising construction costs, and a growing appetite for simplicity, the Boxabl Casita has emerged as one of the most talked-about compact homes in recent memory. At just under 400 square feet, the Casita’s floor plan challenges long-held assumptions about space, comfort, and permanence—offering a carefully engineered alternative to traditional residential construction.
More than a novelty, the Casita represents a broader shift in architectural thinking: one that prioritizes efficiency, repeatability, and thoughtful spatial design over sheer square footage. To understand why this floor plan has captured such attention, it’s worth examining how every inch is planned, how the spaces function together, and where its strengths—and limitations—truly lie.
Understanding the Boxabl Casita Concept
The Boxabl Casita is a prefabricated, foldable housing unit designed to be shipped efficiently and deployed quickly. When unfolded on site, it reveals a complete studio-style home with integrated kitchen, bathroom, living area, and sleeping space. The floor plan is fixed, highly optimized, and engineered for mass production.
Unlike custom tiny homes, the Casita’s layout is intentionally standardized. This allows for predictable performance, faster permitting in some jurisdictions, and consistency in construction quality—attributes rarely associated with small-scale housing.
Floor Plan Overview: One Space, Many Functions
At first glance, the Casita floor plan appears deceptively simple: a rectangular volume divided into three primary zones. But its effectiveness lies in how those zones overlap and support multiple daily activities without feeling chaotic.
- Main living and sleeping area: A flexible open space designed to accommodate a sofa, bed, or convertible furniture.
- Kitchen wall: A linear galley-style kitchen with full-size appliances compressed into a single plane.
- Bathroom core: A fully enclosed wet-room-style bathroom positioned for efficient plumbing runs.
This zoning minimizes circulation space, ensuring that nearly every square foot contributes to daily living rather than hallways or transitional areas.
Spatial Efficiency and Ceiling Height
One of the most surprising aspects of the Casita floor plan is its ceiling height. Higher-than-expected ceilings visually expand the interior, counteracting the small footprint and improving daylight distribution. This vertical generosity allows the space to feel less like a trailer and more like a compact apartment.
Large windows further enhance this effect, establishing a strong connection to the outdoors and reducing the psychological weight of compact living.
Kitchen Layout: Compact but Complete
The Casita’s kitchen is designed as a single, efficient wall. It includes a refrigerator, cooktop, sink, microwave, and storage—all scaled for everyday use rather than compromise. This is not a camping kitchenette; it’s a functional cooking zone intended for real meals.
The linear configuration keeps plumbing and electrical systems consolidated, reducing both manufacturing complexity and long-term maintenance concerns.
Bathroom Design: A Self-Contained Core
The bathroom occupies a surprisingly generous portion of the floor plan, reflecting a deliberate prioritization of comfort. Featuring a full shower, toilet, sink, and ventilation, it mirrors the proportions of a conventional apartment bathroom rather than a recreational vehicle.
By concentrating all wet functions into a single core, the Casita maximizes efficiency while minimizing the risk of water-related issues elsewhere in the unit.
Comparing the Casita to Traditional Studio Apartments
| Feature | Boxabl Casita | Typical Studio Apartment |
|---|---|---|
| Square Footage | ~375 sq ft | 400–600 sq ft |
| Construction Method | Factory-built, modular | Site-built |
| Kitchen | Full galley wall | Varies widely |
| Bathroom | Fully enclosed | Fully enclosed |
| Deployment Time | Days | Months or years |
Furniture Strategy and Daily Living
The Casita floor plan assumes intentional furniture choices. Convertible sofas, wall beds, and integrated storage allow the primary living space to transform throughout the day—from lounge to bedroom to workspace.
This adaptability is essential. The floor plan performs best when residents embrace minimalism and flexibility rather than attempting to replicate the storage density of larger homes.
Natural Light and Visual Expansion
Window placement in the Casita is strategic rather than abundant. Each opening is sized to frame views, admit daylight, and maintain privacy without excessive heat gain. This balance supports thermal efficiency while enhancing livability.
The result is a space that feels intentional and calm, not cramped or overexposed.
Comparison: Casita vs. Tiny Homes on Wheels
| Aspect | Boxabl Casita | Tiny Home on Wheels |
|---|---|---|
| Mobility | Relocatable, not road-driven | Road-legal |
| Ceiling Height | Residential-scale | Often constrained |
| Bathroom Comfort | High | Variable |
| Code Compliance | Modular housing codes | RV or local codes |
Practical Guide: Is the Boxabl Casita Right for You?
The Casita is best suited for homeowners seeking a guest house, ADU, backyard rental, or minimalist primary residence. Before committing, evaluate zoning rules, foundation requirements, and utility connections in your area. Consider how much storage you truly need and whether a studio-style layout aligns with your daily habits.
Those who value speed, predictability, and efficient design often find the Casita compelling. Those seeking customization or multi-bedroom layouts may not.
Long-Term Livability and Adaptability
While the Casita’s floor plan is fixed, its use cases are not. It can function as a short-term rental, remote office, aging-in-place solution, or transitional housing. Its neutrality allows occupants to project their own lifestyle onto the space without architectural friction.
This adaptability may prove to be one of its most enduring strengths.

When we began our initial research and development in 2017, we asked ourselves why housing wasn’t being mass produced at a factory like almost every other major product category in the world. We began developing a building system that had the potential to solve that very problem. Through our patented production process, we’ve been able to create a platform that allows for modular, prefabricated homes that are produced at scale in a factory and can fold up for transportation to the final installation location. Because of this, we believe the Casita has the potential to bring high quality, affordable homes to the mass market in ways that have never been done before.
While we believe the Casita, our 19ft x 19ft 361 sq ft studio style home, is going to kickstart the affordable housing revolution, we also have big ambitions on how we plan to build the world. At our core, our patented manufacturing process will allow our products to be scalable to allow people to construct their dream house in many different configurations. Our Casitas can be stacked and connected to create larger structures, and we are in the process of exploring the addition of larger base units to our product lineup to create even more possibilities for what people can build using BOXABL as their base.
The potential impact of our products will go way beyond just the individual consumer. We believe that there is limitless potential on the large-scale development side of things where entities such as housing developments, governments, workforce housing projects, and tribes will be able to utilize our products to deploy their potential projects effectively, efficiently, and at scale. We are just getting started!
