actually the house does have some of those things you wanted added. not a garden or animal pen tho. I'm gonna write a couple scenes you get in the house and I'm gonna try and put it far down so if you don't wanna know exact stuff it doesn't spoil it for ya.
I'll start with a (currently) one time event, Logan visiting your house after certain events have been completed/done until a certain stage. you also gain the chance to have sex with him but it gives a black heart after.
repeatable event next, Barrel's visit. your just gonna need the house (kinda obvious but like just saying that in case lol) and a certain amount of like with him. he just shows up randomly and you can let him in or not.
and a unique event last, you can get a scene with Feliar if you choose him to watch the firework's with at the end and invite him to your house.
