nice base, but why can't you get to the third floor? just build floors towards the existing roof? you already have the stairs. And you cannot build stairs below a roof, because the top of the stairs cannot be blocked. If you puncture a hole through the roof (sledge or pick up/dissemble tiles), then you can fit the stairs (heads up it's not easy to figure where to puncture the roof to align with how you the envision the stairs to be below though)

I tried several times, it turns to red on all locations.
