2011 11/09 I gave (as my FBW 32, revised some from in FBW.Z) how multilevel homes cylinders (having 14 2m levels, with the 8m radius central effective 4*2m "levels" actually being one open volume, being good as an open shared play park central volume in each such homes cylinder), might be well formed most convenient for many to live closer than in Earth city-blocks houses, while having shared inner yards & shared fruits bushes & trees inside between the ends of a homes cylinder. Since a Fullball world is largely an air filled balloon world, all weights within even a much enlarged one will stay virtually zero throughout, (great for most easy air swimming to reach nearby friends).
