If you were in Navy Yard this weekend taking in a Nats game, you may have seen a small, rectangular box parked on a stretch of grass with people coming in and out.

No, this wasn’t some new microbrewery or rosé garden. It was actually a tiny home.

But don’t call the Kasita a mobile house, says COO Benji Miller. It’s actually a modular home, meaning that while you can move it if need be, it’s not designed to be transported from place to place. The Austin-based brand was in town for the weekend to spread the gospel of small-scale living. The 400-square foot homes are artfully designed, with the kind of neutral-hued, minimalist aesthetic you’d see in a trendy hotel.
