One of my good friends has been running a small design studio from home for about 15 years. One tip he taught me was that you still need a “commute”. For him it is a 10 minute bike ride to a coffee shop that is further away. When he comes back he is “at work”.
My other recommendation is a good HiFi! I’m biased here based on my last gig but one of the coolest things about working from home is you can crank the stereo and get lost in the work. 
I’d also recommend getting some big gator board sheets (usually come in 3’x6’ or 8’ I think) so you can pin stuff up and move it all around easily.
