Can't see the outline of stairs on snowy ground to know where to put them. Particularly troublesome the first time building since I don't know what they'll look like or how much space to take or what orientation will be.

Perhaps green could be used as the okay color for construction instead of white....Green/Blue: construction is possible; red: construction is not possible
