I agree! Although there are already a few furniture pieces that are old european style, they are very few and lacking in a lot of the categories. Curtains is one of them: we need less modern, more detailed curtains. Built-in bookshelf and cuppoards are needed to.
More architectural elements in this style would also help create the cottage core / old european town style. Somebody already made a great post about the addition of trims, moldings and other building features that would help make houses look less “modern” here. There’s also a lack of archs and less modern looking windows and doors, particularly double doors (all of them are so modern they barely fit any building that isn’t a modern appartment).
