I have ADHD. I doubled my productivity going remote and working from a well curated home office.

Charging station for my phone just inside the room, good sitting/standing desk and chair, good laptop, with a dock, 3 displays. A desktop with a vertical monitor I use for teams chat, technical documents, and work management only. Second laptop used for secure prod access tucked under a monitor riser until needed. Whiteboard. Couch with a small station for engineering journaling. I also take video calls from the couch often. Treadmill and elliptical, TV for watching YouTube tech videos while I'm taking a fitness break, bookshelves for my collected engineering journals and useful books. Roughly 275 sqft. Virtual body doubling helps sometimes but is hardly needed.
