You can only own one establishment, however you can own all of the environments and receive the buff for the level of your establishment. The Buffs do stack. The particulars of how this works is that if you own a Tavern and buy all of the Environments you will receive 200 Health, 200 mana, 2.0 Damage, and 2% luck reroll. If you decide to downgrade to a Cottage, you still keep the environments but the benefit is reduced to 50 Health, 50 mana, 1.0 Damage, and the luck is no longer applied.
Come on, 1k plat for just 200 mana/health...?
