The styles outlined here are very similar to an ID company. I can't tell if the design are by them but it could also be coincidence. After adding the features outlined, the property seem to have an elevated look (ATAS look)
Style 1 : Add a thin blanket with very funky colors or nice geometry over the sofa.
Style 2 : Add in props like a simple fake wheatgrass plant (bought at Ikea) and a bedside table on the bed
Style 3 : Add in painters tape to create very unique outlines
