Houses in Forza Horizon 5 serve several functions and are as important to unlock as races. Houses can help you unlock active perks and also serve as quick transit stations and a location for you to change your character’s look.
Forza Horizon 5’s houses, with the exception of your first, which is provided to you for free, are unlocked by completing Expeditions. These story-based quests act, requires you to complete a variety of goals in order to eventually establish a new outpost.
To reveal each house on map you must complete an Expedition. Focus on unlocking the first tier of each Adventure as fast as possible to reveal the houses.
