Answer 1

When building with less stable/strong materials like mud or straw, round is stronger —no weak pints at corners. But when building with modern methods where strength isn’t an issue, straight lines are easier to have standard materials, fit in gridded lot lines better, make it easier to place furniture and built-in cabinetry/shelving, etc.
