Instead of building a curved wall, an octagonal shape can be used.
AdvantagesDisadvantages
- If combined with top arched windows (Spanish or Morisco style), the building will still seem round and therefore the architectural design will have been achieved.
 - The cost increase is not so high if built with angle blocks.
 
- It is not completely round!
