Steel Frame Modular Construction

Modular building is a form of construction where portions of a building are built off-site, preassembled in sections called “modules” and are installed at the job site.  This process is often called “prefabrication” or “prefab construction.”  OneBuild steel frame modules reduce on-site labor by arriving onsite completely finished with unit MEP, drywall, paint, doors and windows, flooring/carpeting, casework, countertops, built-in furniture and media systems, appliances, kitchens and bathrooms.  Module layouts and dimensions are flexible and can be customized to meet the specifications of almost any project, design, or architectural style. 

OneBuild offers many advantages over its competition including:

Higher quality and consistency

Unlike most wood frame modular manufacturers, OneBuild modules are steel frame which is an inherently more accurate and precise building material unaffected by weather and warping, and allows for easier transportation and onsite assembly.  In addition, OneBuild's manufacturing and quality control processes combined with our factory controlled environment result in more consistent construction.  Our use of computer-aided design and manufacturing systems results in greater precision and increased efficiencies. 


Increased cost efficiency

By applying manufacturing discipline to construction processes, OneBuild achieves greater cost efficiency as compared to traditional building.  OneBuild employs a unique application of existing steel frame manufacturing infrastructure that reduces both costs and development timelines.  OneBuild also engages the procurement chain at the source reducing overall material cost.


Faster development timelines

With modular construction, 85% of the project can be completed in a controlled factory environment which eliminates project risks associated with schedules, subcontractors, weather, delivery, and inspection.  Once the building permit is issued and the general site work begins, the factory is simultaneously fabricating the building modules.  This process of parallel site work and module fabrication can shave months from a project's delivery date and reduces on-site disruption


Increased sustainability

Modular construction is inherently greener and more efficient. Modules can be designed to LEED standards, and building in the factory reduces the amount of waste, carbon footprint, and impact on greenspaces at or around the jobsite.  OneBuild has worked on a variety of projects that have been designed to LEED or Built Green standards.


Significant experience in relevant building jurisdictions

OneBuild has supplied over 150k square feet of modular product primarily for the Washington State market, and specifically Seattle.  Our team has received approval from Washington State Labor & Industries (the authority having jurisdiction over factory assembled structures in the state) on multiple modular projects.  Having successfully navigated the modular building approval process in the Seattle/Washington jurisdiction previously, we can effectively and efficiently identify the design and building approval risk areas associated with a modular project and can properly implement strategies to mitigate.  Our team holds substantial building and general contracting experience and understands the issues and risks building in the city of Seattle and Washington state.  Sufficient resources are allocated to each project during design and manufacturing to ensure full code compliance is achieved.  Lastly, OneBuild has the ability to leverage existing relationships with local design and building partners, and has a thorough understanding of how steel frame modules are assembled onsite.
