No idea, this house is close to 50 years old and the door is at least 35, but the first time I remember my dad sanding it down was probably around the 18 year mark. There is a huge problem with humidity in the entire section of the city, with most houses developing saltpeter and needed re-plastering the walls constantly.

In my experience, cockroaches very rarely travel through the front door, unless you have a real serious infestation problem on the streets like literally just stepping outside and seeing a cockroach scurry off. Or maybe it's just that my house is too uninviting ...too many spiders, ants and geckos behind the furniture that will predate on them before they get close. After I put some of those sleeves and trapdoor valves in my drains I haven't seen a single one inside in years.
Some people will have these though, but obviously they look incredibly tacky; while yours seem like a major tripping hazard and a major obstacle for moving large furniture in or out; like, maybe there's perks to being a neighbor of Sweden, but just 20 years ago flatpak furniture was a still a novelty here, mostly relegated to dry, monotone, ugly, and cheap office spaces, not homes.
