[Pymeus]

We solve the junk issue by having save pits instead of save rooms. You can buy permanent fixtures for any part of your house, like furniture, portals, fountains, and various tools, but any loot you want to store has to go in a special container that gets saved across reboots and crashes.

As far as poor quality, house building/alteration is carried out by staff members for exactly that reason. We want our players to exercise their creativity, so mainly we weed out spelling/grammar issues and the really major thematic conflicts. Players can and do get pretty creative with their houses. Town houses are somewhat restricted by the fact that they're in a city, but the manor houses granted to mid-tier nobles can be put almost anywhere and be almost anything; it need not resemble a house at all. Some are valleys, some are labyrinths, one is a tree, and there used to be a ship out by the coast.
