The modular construction industry has long been heralded for its efficiency, cost-effectiveness, and ability to deliver high-quality homes. However, a recent conversation with a veteran modular builder unveiled a trend that might redefine how we think about prefabricated housing.

This builder, with decades of experience, is now exploring the use of individual components to construct new homes and townhouses. This shift from complete modular units to component-based construction could offer numerous benefits, including reduced transportation costs, fewer regulatory hurdles, and more flexible building processes. He remains anonymous at this time because he doesn’t want his modular factory to know. (understandable)
The Shift to Components
The builder has begun investigating various components such as panelized walls, roof and floor trusses, dormers, and bathroom pods. He is also exploring Structural Insulated Panels (SIPs) for walls and roof systems, discovering the added convenience of pre-installed exterior doors and windows within these panels.
Advantages of Component-Based Construction
One of the significant advantages of building with components is the elimination of mandatory third-party inspections required in modular home factories. This reduction in regulatory oversight can streamline the construction process and reduce administrative costs. By avoiding the need for factory-based inspections, builders can expedite project timelines and avoid the delays often associated with these regulatory checkpoints.

Transportation of modular units often involves oversized loads, necessitating special permits and routes, which can drive up costs and complicate logistics. In contrast, components such as panelized walls and trusses can be transported more efficiently, minimizing transportation costs and the logistical challenges of moving large, prefabricated structures. This efficiency can be particularly advantageous for projects in remote or difficult-to-access areas. Transportation costs are usually built into the quote and rarely fluctuate.
Building with components also simplifies regulatory compliance. Traditional modular construction requires extensive state plan submittals and can face significant backlogs due to the detailed review process. Component-based construction, on the other hand, typically involves fewer regulatory hurdles, allowing builders to proceed with construction more quickly. This streamlined compliance can lead to faster project completions and reduced bureaucratic delays.
The builder’s familiarity with local code enforcement officials adds another layer of benefit. Since he builds primarily within specific regions, he has established relationships with these officials, which can facilitate smoother inspections and approvals. After completing one house using components, he feels confident that local inspectors will be more supportive of this construction method, easing the regulatory burden even further.
The Search for Comprehensive Solutions
While the builder is already impressed with the benefits of component-based construction, he is still on the lookout for a factory capable of building and installing kitchen and laundry pods. These pods would streamline the interior fit-out process, allowing for quicker, more efficient home completions. These could be the hardest components to source.

Why Builders are Considering Components
The transition from modular units to components is not merely about logistics and cost savings. It also represents a shift towards greater flexibility and customization in homebuilding. By selecting and assembling individual components, builders can tailor homes more precisely to the specific needs and preferences of their clients. This modular flexibility allows for greater architectural variety and the ability to adapt to varying site conditions.
Challenges and Considerations
Despite its advantages, component-based construction is not without its challenges. Builders must ensure seamless integration of various components, requiring meticulous planning and coordination. Additionally, while the reduced need for factory inspections and state approvals is beneficial, it places greater responsibility on builders to ensure compliance with local building codes and standards.
Modcoach Note
The exploration of component-based construction by a seasoned modular builder could signal a trend in the offsite industry. By leveraging panelized walls, trusses, SIPs, and pods, builders can enjoy greater flexibility, reduced costs, and streamlined regulatory processes. As this approach gains traction, it has the potential to revolutionize the homebuilding landscape, offering a compelling alternative to traditional modular construction. Builders, developers, and homeowners alike should keep a keen eye on this evolving trend, as it promises to deliver high-quality, customized homes with enhanced efficiency and reduced complexity.
