Smaller, relative to this megastructure, because its a new fabrication process - better to see how it performs on a smaller-scale both in terms of desirability (is it pretty - will people happily work/live in it) and structural integrity. Plus there needs to be demand for huge amounts space.

I know people from the engineering side of things who would be interested.

I also know people who may be interested. I put my email in my profile, if you want to look into this, send me a note.
