Below is Zindikasheen's quick guide to house formations and their respective required levels of carpentry, up to level 20 (non-premium limit). If you have a higher skill you shouldn't need a guide hehe. **NOTE: if you do not see a formation here assume it requires the same level as the largest required level for that number of tiles**
