Custom Prefabricated
Post & Beam Homes
Since 1968, Topsider Homes has specialized in the custom design, engineering and precision fabrication of distinctive custom homes using our proprietary Post & Beam panelized building system. Unlike modular, manufactured or mobile homes, every Topsider home is individually designed for its owner, engineered for its homesite and precision fabricated in our North Carolina facility before being shipped for assembly and completion by qualified local builders. Unlike production prefab companies, no two Topsider homes are alike. The result is exceptional architectural freedom, outstanding quality and a more efficient building process.

What Makes Custom Prefabrication Different?

Most people think of prefabricated homes as standard floor plans built in a factory. Topsider takes a completely different approach. Every Topsider home is individually designed for its owner and engineered specifically for its building site.
Topsider's proprietary post & beam panelized building system allows major structural components to be precision fabricated before shipment, providing high quality, architectural flexibility and efficient construction without sacrificing customization. Prefabrication isn't about producing identical homes more quickly. It's about combining custom architecture with precision fabrication to create a better home from the very beginning.
Understanding what "prefabricated" really means is the key to understanding why Topsider homes are fundamentally different from modular or manufactured homes.
What Is a Prefabricated Home?
A prefabricated home is manufactured in a controlled production environment and shipped to the building site for assembly. Topsider utilizes an advanced panelized building system in which major structural components are engineered and fabricated before shipment, improving quality, construction efficiency and long-term performance. Unlike many factory-built homes, Topsider's panelized approach allows virtually unlimited architectural flexibility while preserving the quality and efficiency advantages of prefabrication.
Once you understand our approach to prefabrication, the next difference becomes obvious—every Topsider home begins with custom design rather than a standard floor plan.

Frequently Asked Questions
What is a prefabricated home? A prefabricated home uses structural components and panels that are precision fabricated before shipment to the homesite for assembly. This approach improves quality control, reduces material waste and helps streamline construction.
Are Topsider homes modular? No. Topsider homes are custom post & beam homes built using a proprietary panelized building system. They are not modular, manufactured or mobile homes. Learn more about the difference here.
Can I customize my home? Absolutely. Every Topsider home is custom designed. You may begin with one of our design concepts, bring your own plans or work directly with our design team. In the end, every home is custom-designed to meet client needs, styles and preferences, building site conditions and local building code requirements.
Who builds the home? Your home is assembled and completed by a qualified local builder or contractor. Topsider provides engineering, technical support and construction coordination throughout the project.
Where can I build? Topsider homes have been built throughout the United States, the Caribbean and internationally. They are especially popular for waterfront, coastal, mountain and other distinctive homesites.
Why choose panelized construction instead of modular? Panelized components are engineered and fabricated for your specific design and building site, so architectural details, rooflines and window placement aren't constrained by a factory floor plan or highway shipping limits the way modular sections are. You get the quality control benefits of factory fabrication with the design freedom of custom-built construction.
