Best Duchy Building for expansion

Military Academies are the best Duchy Building if you’re map painting/conquering a lot. This is because it increases the number of Knights you can wield, making early battles much easier. It also reduced Army Maintenance, meaning you’ll not go bankrupt waging war early.

Best Duchy Building for early game

Leisure Palaces are a fantastic early game choice because of their Realm and Duchy modifiers. The bonus to prestige is incredibly good, and because of the sheer amount of stress in the early game, any way to reduce it quicker is better.

What’s more, the Leisure Palaces improve scheme success chance, making them perfect if you’re planning for lots of intrigue and assassinations.

Best overall Duchy Building

Marches are the best overall Duchy Building at any point in the game. The sheer range of bonuses make them perfect for your most favorable Duchies. A defensive and offensive choice, getting a bonus to supply limit, levy reinforcement rate, and garrison size is huge. And the slow down in raid speed makes it perfect to allow you to react to any hostile invasion.
