The opportunity has already presented itself. The chemistry seems to go well between you both, but I would continue to build that foundation of the relationship and friendship. Continue to dive deeper. See where the compatability lies and then keep developing that bond. When that bond feels strong and tight-knit, ask her out.

You want to avoid only going out with her because of the physical sense, when and if things fall by the waste side because there was no strong bond. And that's coming from experience. So keep making yourself known, keep going out on dates and hanging out. Keep her close, but be careful about moving too fast and falling too hard. Take it slow, but not always too slow or too fast.
