Deep customisation options are also provided, allowing players to decorate every surface freely, from kitchen shelves to ivy on exterior walls. Interior work can be carried out without being shackled to specific house styles or worrying about mistakes. Additionally, there is a greenhouse that can be filled with rare plants discovered during travels. Cozy Builder grants complete access to all interior features, offering an experience where players do not just look at what they have made, but actually live inside it.

Various people live throughout the valley, and the homes being restored belong to these local residents. As spaces are filled up, the villagers become great companions, and every restored house turns into a proper residence for someone. Beyond reconstruction work, time can be spent exploring the hills of the valley, harvesting grapes and olives, and foraging for herbs, wildflowers, and rare plants.

In the afternoons, players can take a break from construction to enjoy activities like cooking, treasure hunting, and jewellery crafting. There are no combat elements, failure states, or time limits, meaning nothing in the valley has to be done in a specific order.
