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 prefab 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.
Fire
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.
Earthquake
Earthquake–resistant 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.
wind
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 PREFAB
Prefab homes are constructed with the same quality materials as stick-built homes. Roof and Realm® homes are built in climate-controlled building facilities. The efficient assembly line process and minimized weather delays cut back the time it takes to build a modular in comparison to stick-built homes.
Details that Matter
Simple Luxury interior designs by Roof and Realm mix style with pleasure and ease for
every aspect of daily life by choosing current materials, finishes, elements, and room designs that are
on-trend while also maintaining inviting softness and utility.
SOLAR READY OR SOLAR INCLUDED
Roof and Realm offers the option of solar-ready homes and includes solar in each structure over 1000 square feet. They can be outfitted to be Net Positive, which means on an annual basis the home will create more energy than you use. All of our homes are designed with the latest in energy standards of your local energy code requirements and also include efficient heating and cooling systems.
