Here are a few examples of building upgrades:
Expansion rooms: Players can add new rooms to their existing structures, such as kitchens, basements, storage areas, or any other functional space that enhances the building's capabilities. These new rooms could serve specific purposes, such as crafting, storage, or providing bonuses to certain activities.
Defensive upgrades: Walls could have upgrade options like adding spikes, reinforcing materials, or defensive mechanisms to deter intruders or improve the building's defensive capabilities. These upgrades could serve both practical purposes, such as discouraging wall hugging or making it harder to breach, as well as aesthetic purposes to make the building visually impressive or intimidating.
