I dont like clutter in the sims I dont have any wall hangings or curtains because I use walls Half down to play and any curtains/blinds and wall hangings (apart from wall mirror in bathroom) cause annoyance when playing. Most of my builds are minimal furniture - I am a builder and focus more on the build and floor and wall coverings than any clutter. I am not keen on clutter IRL to be honest either. The only time I used clutter was in a 'messy tiny apartment' for a poor family in San Myshuno - that was one save out of hundreds over the years.
@fruitsbasket101 I agree about the homes being practical! - If I download a property I always have it unfurnished and delete all the trees/ plants/flowers/rocks etc immediately. I wish if you hit 'unfurnished' it would delete all the plants trees and landscaping materials too.
