The Elements for Roof and Realm

Roof and Realm has converted the typical modular home into “THE REALM SERIES”, a series of Architectural Styles to meet your needs and design standards. The main premise is to protect your home from the forces of nature: wind, fire, and earthquakes. Our modular and modular homes are designed to mitigate such forces and keep you and your family safe.

With so many options available, the design possibilities are endless. From custom colors to your pick of trims ranging from siding, stucco, batten board and other materials, Roof and Realm will accommodate any request. 


Though It is impossible to build a fully fireproof home, Roof and Realm has researched the production of making homes fire resistant. Roof and Realm is one of the few modular home builders that recognize the effects of climate change. The increasing intensity of wildfires around the world puts billions of dollars worth of real estate literally in the line of fire.


Earthquakeresistant construction involves the fabrication of a building or structure that is able to withstand the sudden ground shaking characteristic of earthquakes. This type of build is intended to minimize structural damage and human injuries that may otherwise result from less stable structures.


It’s essential that storm-proof homes have strong bones. A popular choice is reinforced steel which is a tough and dense material. When used correctly, it can withstand destructive high winds and flying debris. Steel is favored over wood as a structural option due to its high degree of rigidity.

Roof and Realm is the only home builder to build steel-framed ADUs. We developed a process to protect the environment,
preserve resources, and reduce pollution to provide a new style of construction that is healthy, practical, and efficient.

Why modular

Building modular can offer a range of benefits, including speed, cost-efficiency, lesson the foot traffic on property, high-quality construction, sustainability, and flexibility.

A modular approach would involve:

  1. Factory Production: Modular units are built in a controlled factory environment. Skilled workers construct each module, which includes the framing, exterior and interior, plumbing and electrical work.
  2. Simultaneous Work: Multiple units can be produced simultaneously, with specialized teams working off different sections of each module.
  3. Quality Control: Each module undergoes rigorous quality checks in the factory, ensuring consistency and precision in construction.
  4. Site Assembly: Once the modules are complete, they are delivered and installed on the property. The efficient assembly line process and minimized weather delays cut back the time it takes to build modular in comparison to stick-built homes.
