The Quadrow Story

The Quadrow Modular System was founded in 2015 in Indio, CA by Toshi Ghalebi, an engineer and inventor.   He was inspired to support the Cultivation industry with greenhouses using magnesium oxide boards instead of drywall to provide the cultivation industry with a kit ready grow house that resists mold.

As he continued to research the demand for modular units or ADU’s, he designed modular units that could easily be manufactured using an 8 x 8 cube system. These modular units are also built with magnesium oxide panels that can resist fires, floods and earthquake to be used for residential, commercial education, healthcare and other forms of construction.  The Quadrow Modular System was born to be able to meet the demands of affordable housing on a local, national and global scale in meeting with environmental objectives.

Modular construction refers to the process of taking prefabricated units, which are built off-site and pieced together at the job site or homestead.  The material the company uses to build homes can survive over 800 degrees.The walls are made of magnesium oxide and are supported by steel. Our ADU’s and tiny homes can be retro-fitted with floating devices making these this units favorable to frequent flood areas.

Market Demand

"The market demand and popularity of modular units fit into many housing lifestyle needs, growing industries and cost saving commercial warehouse options."  Toshi Galebi

Modular construction is a hot topic within the industry.  Per the U.S. Census Bureau, the rise of urbanization and population growth means that people are moving into cities faster than ever before, and these individuals need places to live, work and stay.  Hotels and apartments are particularly effective uses of modular construction units. Companies like Google, Starbucks, Marriott and even tech companies like Autodesk, are betting big on offsite construction, investing millions of dollars into the method.

The customer can essentially design to build, and the product comes as a kit ready to assemble. The product comes prepared for easy installation and connection to utilities and infrastructure. Customers can provide a basic rendering of their plan which will be converted into a spec with set pricing. The product is easily altered to fit any terrain and is built to suit the buyer and their specific needs. Quadrow, Inc. has also developed a new optional feature whereby structures can be equipped with collapsible stilts that will allow for floatable options in flood prone areas. This new feature includes utility and water systems that are manufactured using a plex material that stretches, and collapses and will rise to allow for uninterrupted flow of utilities.

Benefits For Homeowners

For homeowners, the prefabricated modular units or ADU’s appeal to the time and cost savings attributes of modular construction. Perfect for retired adults looking to downsize, or Millennial’s looking for affordable housing, as well as the travel adventurer looking for a Tiny Home on wheels and “Off-The-Grid” sustainable housing environmentalists. The modules can consist of parts of a room, an entire room, or an individual unit, which is fitted with other components at the job site for form a complete structure.


Proactive safety planning helps us provide a safe working environment for everyone working on the project, people visiting the job site or working.


To become an industry leader, it is important for us to encourage team work in order to solve any construction challenges and to achieve results.

Benefits For Commercial Businesses

Building costs and set up times can save thousands of dollars in labor costs. Modular construction requires less time and labor to complete. On a typical project where workers erect the building from scratch at the job site, builders must first prepare the site, then lay the foundation, and then begin the actual building process. With modular construction, off-site manufacturers handle the building process away from the project site, meaning that crews can lay the foundation simultaneously. Modular construction is also generally touted as safer than other methods. More akin to manufacturing than typical construction, modular construction processes are much more predictable and repetitive and can be documented, analyzed, and modified to maximize efficiency and safety.
