Mockup into the next life

Second Life has this profound ability to allow you to mockup just about any idea instantly. I am a person who gets tired of looking at my storefront and needs change every few months. I’m trying to come up with some ideas for the look of my next storefront. I like the idea of openness and having a feeling of large areas. Still, I try to keep the building within 64 meters square. My last building was built over the skeleton of my sister in-laws building. This next version will purely be me again. For some reason, I like circles. The whole building will be a circle. I think I need real walls though.
