Design details
About This Commercial Building
This commercial building is 50 feet wide, 40 feet long and 12 feet tall, with a Vertical roof style. It is finished in Zinc Gray on the roof, Zinc Gray siding and Galvalume trim. We can build it at this exact size or change any part of it.
The Four Bay Commercial Shop or 4 Car Shop, is a versatile metal building designed for businesses that need multiple access points and efficient workspace. This configuration maximizes operational flexibility by providing four separate entry points for simultaneous projects and improved workflow management.
With four large bay openings, vertical metal roofing, and enclosed walls, this structure accommodates high-volume operations requiring quick vehicle or equipment turnaround. The multiple access points eliminate bottlenecks during busy periods.
Each bay operates independently, allowing businesses to segregate different services or handle multiple customers simultaneously. This design increases revenue potential and customer satisfaction through reduced wait times.
Versatile Business Applications
This Four Bay Commercial Shop is perfect for automotive shops, equipment storage, or service-based operations. Auto repair facilities benefit from dedicated bays for different service types like oil changes, diagnostics, and major repairs.
Equipment storage operations can organize inventory by category or size across the four bays. Service businesses such as fleet maintenance, heavy machinery repair, or specialty vehicle restoration find the layout ideal for complex projects.
The enclosed design protects valuable tools and equipment while maintaining professional appearances for customer-facing operations. Climate control options create comfortable working conditions year-round.
Durable Four Bay Commercial Shop Steel Construction Benefits
Its open layout provides ample room for vehicles, tools, and workstations, while the steel construction ensures strength and long-term durability. The clear-span design eliminates interior columns that could restrict workspace or equipment placement.
Use this design as a base in the 3D configurator to customize the size, layout, and features to match your specific commercial needs. Customization options include door types, window placement, and interior partition systems.
The steel framing resists weather damage and requires minimal maintenance, reducing long-term operational costs while providing decades of reliable service for growing businesses.

Roof styles
Which Roof Style Is Right?
This build has a Vertical roof style. Here is how the three styles compare.
- This build
Vertical roof
Panels run from the peak down to the eave, so rain, snow and debris slide off fastest. It carries the strongest wind rating and is our top pick for most of our service area.
- This build
A-frame (boxed eave) roof
A peaked roof with boxed eaves and horizontal panels for a clean, house-like look at a lower price than vertical.
- This build
Horizontal (regular) roof
Rounded eaves with horizontal panels. It costs the least and works well in milder weather. We do not warranty horizontal roofs on buildings longer than 36 feet.
