Most of the main station (exterior) doors are walk-in style. The same goes for most of the scientific outbuildings. A lot of the smaller outbuildings, like the climbing gym, have relatively "normal" doors.
There is a lot of wood construction, because it insulates well, it's light (extremely important for cheap construction), there's no moisture to speak of, and it's easily repaired. A lot of the walls are wood with a ton of insulation and metal cladding [0]. The windows are beefy, though weirdly they were designed in with metal frames which I imagine leak a lot of heat. Most of the interior construction feels somewhere between a corporate and a university space. It was built by government and defense contractors, so there is also a bit of a barracks feeling about it too.
