I put the scene which contains the house and all other materials but the house itself counts: 24.047 polys. And whole scene counts: 110.640 polys. So you can delete all other stuff, it’s up to you.
Doors and windows are funcional and all stuff has been linked to ’’house_base’’ object which is the first flour of the house.
The house inside is empty, there’s no items, models in it.
