All relationships are a risk whether they are professional or personal. Since this is the only at you've found so far that is good enough I think it's worth taking the risk to continue with her. This is comparable other relationships - if you find fault with people so you can avoid the risk of getting hurt, you'll miss our on the good relationships too. Nothing in your life will change. And I think the relationship is bound to grow over time, whether it grow in the way you want it to is something you'll discover in the future. The office atmosphere is a downside for you but life requires the ability to be flexible. I go to an office like that and it's fine. This sounds very promising to me so I would focus on that and just try her for a while.
