That reminds me of when my neighbors built theirs a couple of years ago. Everyone thought it would just be a place to park the truck, but it slowly turned into the most useful building on their property. They keep lawn equipment in one section, bicycles along one wall, and even set up a small workbench for weekend projects. The advice they always give is not to underestimate how quickly you'll fill the extra space. They originally planned for a smaller building, but after talking through everything they wanted to store, they chose a larger size and have never regretted it. Another smart decision was adding extra windows for natural light because it made working inside much more enjoyable. If you're still comparing options, it's worth thinking about what you'll need several years from now rather than just what fits today.
