I really believe that extended patios are a great way to test the waters for more pedestrian-friendly communities. If they turn out to be successful, perhaps they could be made permanent. However, I do understand the need to put them away when they are not in use and allow for more parking and road use in the winter. That would be an efficient use of space. I have to say, I have never seen an extended patio that didn’t improve the space it’s in. It just makes everything feel more inviting and comfortable.
