In a light earthquake zone. The pillars are reinforced with heavy pipe down the center that is also concrete-filled. As with any such building, it is the roof structure (the rafters and especially the roof sheathing) that reinforce the build and prevent wobble in the supports. This type of construction has a lot less wobble in the support structure (before the roof is added) than a conventional frame building would have, so after I add the rafters and nice, heavy roof sheathing I think it should be "brick outhouse" strong.
