In our L.A. apartment, Matt and I turned the living room into a joint office. It was small but we made it work!
We set my computer up across from the couch and used it as our screen when we wanted to watch a movie together.
Matt was able to keep his boy stuff on one side of the room, and I kept my girlie things over on mine. Our aesthetic was similar enough that the furniture and tech pieces tied the decor together. Add some fresh plants, and it was really nice and homie!
Plus we always had someone to talk to about creative inspiration!
