Player housing needs the Valheim/Enshrouded comfort system.
Every piece of furniture added to your house can add to a comfort level. The rarer the furniture, and the closer some of them are of others, the comfort level can go higher and higher. For example, you could have a table that gets the maximum comfort when close to a maximum of 4 chairs. Some piece of furniture could also add additional buffs.
The higher the comfort, the higher the buff players gets when entering your house. Up to you to balance it. But you could for example split the buff in 2 components. The comfort level dictates the length of the buff. And the actual pieces of furniture dictates the effects.
This could be a very interesting way to diversify a build.
