When a warehouse is too small, operations choke. Forklifts crash, inventory gets damaged, and efficiency plummets.<\/p>\n\n\n\n<p>Designing a <strong>Custom Metal Garage<\/strong> for your home is no different. It is a personal warehouse project.<\/p>\n\n\n\n<p>Most homeowners make a critical error: they measure their <em>current<\/em> cars and build a box just big enough to fit them. This is what we call &#8220;Just-In-Time&#8221; sizing. It works great for manufacturing, but it is terrible for real estate. Why? Because your inventory (cars, boats, tools, holiday decorations) always grows. Your building footprint does not.<\/p>\n\n\n\n<p>As your Supply Chain Director, I am here to walk you through the capacity planning for your new facility.

When a warehouse is too small, operations choke. Forklifts crash, inventory gets damaged, and efficiency plummets. Designing a Custom Metal Garage for your home is no different. It is a personal warehouse project. Most homeowners make a critical error: they measure their current cars and build a box just big enough to fit them.
