Work From Home Wednesdays

I like the idea. I think it is on par with Google's 20% time.

Should your startup have mandatory “Work from home Wednesdays?”

ThredUP co-founder and CEO says prohibiting his employees from coming into work one day a week, allows his team to think big picture, and increases productivity. (Just make sure that work from home day isn’t Friday). ..... It’s easy to get myopic at a startup and become too focused on results and milestones instead of taking a step back and thinking about the big picture

I think this can be taken to work from home on Tuesdays and Thursdays. Rent the space out to someone else those two days.
