Tatami is a sustainable, affordable, and infinitely adaptable building system that is revolutionizing the way the world thinks about housing–and how the world lives.



A modular system of prefabricated standardized building components, Tatami is designed to be a fast, precise, and affordable way to build.

Innovation inspired by tradition

Tatami takes inspiration from—and shares its name with—the gridded system of tatami mats at the heart of traditional Japanese architecture. A single tatami, whose dimensions are based on the human body, is a unit of measurement as well as a base module that generates the three-dimensional layouts of rooms. Similarly, Tatami’s rational, modular grid system allows a wide array of two- and three-dimensional arrangements, as units can be connected both vertically and horizontally.

The Tatami system is designed with smaller grids and micro-modules within each building unit, which allows for precision and flexibility in designing interior layouts and exterior elements like the windows, doors, and skylights.

Fast and functional

Tatami is designed to save time and minimize costs at every stage of the building process, from design and permitting to shipping and on-site installation. All building components are shipped via standard cargo containers—like flat-pack furniture or a large kit of Lego bricks. Typically, a small (30m²) Tatami unit can be erected by two trained installers in a single day.

Variety and flexibility

A variety of Tatami components package functional elements like windows, skylights, and even sleeping and reading nooks into standardized and prefabricated modules. These modules plug into—and can be detached from—the overall Tatami structure to meet to occupants’ needs now and in the future.

A green building material

Tatami’s environmentally friendly mass timber structure offers an affordable, renewable, and quick-to-assemble building material with the strength of steel and concrete and the environmental benefits of originating from sustainable forests. All Tatami structural members and components are recyclable and reusable in other Tatami units.

Japanese tradition meets
American innovation

Tatami brings together the spirit of creativity and revolutionary thinking that has put California at the cutting edge of architecture and technology with New York City's legendary vision, ingenuity, and determination, as well as the reverence for quality, precision, and craftsmanship that has been a hallmark of Japanese design for centuries.


Tatami is the creation of a collaborative team of internationally recognized creative and intellectual partners working to rethink, from the ground up, a global approach to housing in the 21st century.

Delivery time for a Tatami house is six months. That timeframe will be reduced to 30 days once our automated production facilities are fully operational.


Tatami is currently accepting architect-customized commissions. However, a revolutionary e-commerce platform that will allow customers to configure their own housing solutions will launch in late 2019. Available both online and in our showrooms, the platform will offer full user-driven customization through an immersive and photorealistic virtual reality experience.


Mass-market US availability is expected to launch by the end of 2019, followed shortly thereafter by Japan. In the near future we anticipate rolling out internationally across 50 major metropolitan areas around the world, including Paris, London, Singapore, Dubai, Hong Kong, Mumbai, Madrid, São Paulo, Milan, Moscow, Kuala Lumpur, Seoul, and others.


In the ongoing search for solutions to the world’s housing needs, architects, developers, builders, entrepreneurs, and government agencies have looked repeatedly to modular and prefabricated construction.

Why Tatami?

Tatami's promise of being faster and more affordable than traditional one-off buildings has appealed to those who seek to equalize socio-economic disparity and inequality and make homes affordable and accessible to the widest possible audience worldwide.

It’s certainly not a new idea. In the United States, the catalog and department store company Sears, Roebuck sold “kit houses” by mail order from 1908 to 1940. Offering more than 300 models over the years, the Sears Modern Homes included most—but not all—the materials required for customers to erect their house in the roughly 30,000-piece kit that arrived at their doorstep. In the 1920s, the visionary architect and philosopher Buckminster Fuller proposed his famous Dymaxion House, which could be mass-produced, flat-packed, and shipped around the world.

After World War II, prefabrication and modular building again captured the imagination of visionaries around the world, from the more pragmatic high-tech designs of Norman Foster and Richard Rogers to the utopian fantasies of Archigram. In Japan, the rational and utopian architectural philosophy of the Metabolist movement, which combined ideas about modularity with organic growth processes, led to iconic buildings like the 1972 Nakagin Capsule Tower in Tokyo. Designed by Kisho Kurokawa, the tower featured self-contained and prefabricated capsules that plugged into concrete cores and could be joined together to create larger modules and replaced over time.

Housing with a social conscience

Tatami’s flexibility and price point make it a viable solution for meeting urgent housing needs in a variety of contexts worldwide—from the most basic shelter, including refugee and disaster housing, to accessory dwelling units, multi-family housing, and large-scale developments. Tatami works with small-and medium-size developers as well as municipal, national, and international agencies with the ability to commission thousands of units for a variety of housing needs.

A solution for housing the world

Tatami’s mission is to be a global solution to a global crisis of availability and affordability. Because it is designed to International Building Code (IBC) standards and engineered for the strict seismic codes of Japan and California, Tatami has viability worldwide. The units’ exterior walls can be insulated for any climate, from tundra to the tropics, while a range of exterior cladding options works in a variety of esthetic and even cultural contexts, from the most traditional to cutting-edge modern. And since Tatami components are shipped like flat-pack furniture via standard cargo containers, they can be delivered efficiently and affordably virtually anywhere in the world.

At the forefront of sustainability

Tatami’s technologically advanced mass-wood structure, as strong and durable as steel and concrete, is one of the most environmentally friendly materials available. Sourcing from sustainably harvested forests means its fabrication requires little or no consumption of fossil fuels. All structural components and functional plug-ins are recyclable and can be reused in any Tatami structure.

Empowering people to shape their own futures

Tatami puts power in customers’ hands with a simple, intuitive, and transparent process that lets them design for specific functional needs as well as esthetic style and personality. Tatami’s plug-in elements and range of exterior cladding options create almost limitless possibilities for personalization.

Flexibility for life

Tatami’s functional plug-ins can be swapped out or replaced an unlimited number of times, so one’s home can evolve over time as one’s life changes—you don’t have to move whenever you need more (or less) space. Developers and landlords can refigure multifamily dwellings over time, calibrating the number and sizes of units in response to housing needs or market conditions. Since individual building components can be changed repeatedly over time and structures expanded and contracted, the lifespan of a Tatami structure is—theoretically—endless.


Minimally and efficiently designed with inspiration from traditional Japanese joinery techniques, universal connectors join all vertical and horizontal structural components and plug-ins.

Tatami’s revolutionary kit-of-parts approach to functionality packages windows, doors, skylights, balconies, footers, nooks with built-in furniture, and other functional elements into prefabricated modules that can easily be plugged into—and detached from—a Tatami unit. They are the key to Tatami’s unique approach to standardized customization. The plug-ins are offered in multiple sizes that correspond to fractional widths and heights of a full Tatami module—the mini-grids that allow greater flexibility in proportioning interiors and exteriors than other modular building systems. Prefabricated with the same mass timber technology as Tatami’s overall structural system, the plug-ins can be recycled or reused in other Tatami units.


Mass timber load-bearing columns that contain core functionality allow for specific architectural expression through horizontal and vertical expansion that is infinitely more specific than the stacking of boxes that is commonplace in other so-called modular building. Electrical conduits, ductwork, and plumbing lines are embedded within these individual structural elements instead of in a typical centralized core, thereby allowing vents, lighting, power ports, and plumbing fixtures to be located anywhere they are needed—and allowing them to be relocated easily over time.


Tatami’s renewable, recyclable mass timber structural system is the key to its flexibility and affordability. Mass timber describes a category of lightweight load-bearing solid or engineered wood framing materials, including cross-laminated timber (CLT). As architects and developers have embraced this leading-edge technology and more code agencies and municipalities worldwide have approved its use in construction, mass timber’s popularity has been increasing. Projects built with mass timber, including hybridized systems with steel and concrete, range from low-rise housing and university buildings to luxury residential towers.

Mass timber construction offers a number of benefits compared to other building materials. Prefabricated components are assembled under factory conditions that ensure precision and weather-tightness. Sourcing from sustainably harvested forests means its creation involves little or no consumption of fossil fuels. And mass timber inherently offers excellent fire resistance, thermal performance, and seismic resilience.


Tatami structures can be clad in a wide array of materials and finishes, including wood, concrete, brick, and metal, in a variety of architectural styles. Exterior cladding panels are prefabricated with the appropriate thermal insulation required by local building codes at the project location.

Frequently Asked Questions

How much does a Tatami house cost?

Consumer models of Tatami House come in S (30 m²), M (90 m²) and L (180 m²) varieties that can each be customized. The average price is US $800/m² (approximately $74/sq ft), or $72,000 for M. This does not include the cost of land, permitting, delivery, and assembly.

What is the lead-time from order to delivery?

The current lead time from customized order placement to delivery and installation is a brisk six months, which is dramatically shorter than the one to two years that a professionally designed, traditionally constructed house would take. We anticipate that this will fall to under 30 days once our production facilities are fully automated.

How long does installation take?

Assuming your property has already been graded, the assembly of a Tatami house takes less than one day for S to less than one week for L, with a crew of as few as two professional installers.

Will I have to hire an engineer or other outside consultants?

One of the benefits of Tatami is that the process of homebuilding is easy and completely transparent, with all labor and material costs included with your order. You only need to work with us to customize your house, confirm suitability to local building codes, and organize delivery and on-site assembly through our trusted partners. We offer auxiliary architectural, engineering, permitting, and expediting services in cases of greater complexity.

How does the local permitting and approvals process work?

Our patented modular system reduces the time required for architectural design by up to 12 months, as your will receive construction-ready documents with your completed Tatami order. That allows you to start the permitting and approval process immediately—a process you can choose to undertake yourself or empower us to handle for you. And since Tatami is designed to conform to local building codes, you’ll reduce the lengthy permitting and approvals process required with traditional building methods. (Actual requirements vary by jurisdiction.)

Are Tatami homes legal everywhere in the world?

Tatami is designed according to the International Building Code (IBC), and as such can be adapted for use in most parts of the world. We are working with municipalities around the world to make them available wherever there is a need or desire for them, so please let us know if Tatami is not yet available in your part of the world.

Can I get insurance on a Tatami home?

Absolutely. A Tatami house is built to the highest levels of contemporary architectural design, engineering standards, and construction quality. Insurers will treat it no differently than any other house, and may well offer incentives for their use given their more robust sustainability and safety features.

What kind of site preparation and foundation work is necessary?

Tatami is tested for environmental resilience and designed to be assembled wherever there is graded land. No additional foundation work is required.

Is Tatami available for both metric and imperial measurement systems?

Tatami is available with imperial measurements for the US market and in metric units everywhere else in the world. More importantly, however, Tatami is adapted for variations in climate, environment, and building codes around the world.

How does the lifespan of a Tatami unit compare to a traditional home?

However, since it is designed as a modular system of interchangeable, upgradable, and expandable parts—and individual components are replaceable and recyclable—the lifespan of a Tatami structure is theoretically infinite.

Do I need to work with Tatami to make future changes on my home?

Tatami is sold direct to consumers in order to maintain the highest quality and lowest cost. All components are available exclusively through our e-commerce platform and showrooms worldwide.

Can a Tatami house be disassembled and rebuilt in a different location?

Yes. Tatami is designed to be demountable for maximum adaptability, utility, and sustainability and evolve with you in terms of size, function, location, or other considerations. We endeavor to be there for you however your life changes.
