We have a nice old cottage on the property that we are considering renovating to rent out as a year-round residence. It is already winter-insulated but lacks a kitchen/bathroom/toilet. Can we extend it into this "rendered part" of the house? By the way, what is this type of room called and why does the house have one?
I'm just wondering if it would be bad in terms of moisture to install internal waterproofing on the entire room, put up some wet room wallpaper with a wet room mat on the floor. It would be a fun project for me to learn how to renovate a bathroom. So far, I don't know a thing about it, but I would mostly like to know if it's a bad idea for the house's sake!
