They'll do their best, but some of the requirements are incompatible for the covenant as it currently exists.
So she'll have to choose betwen Dedicated Building and Elevated, since none of the independent buildings are 4 stories high.
The Lesser Focus flaw isn't something the covenant can install for her, since it requires the existence of a Lesser Feature, but the raw materials she will need to add those can be provided.
Decaying isn't really something appropriate, since the lab will have just been set up for her. The covenant wouldn't have selected shoddy furnishings and materials.
As for Haunted, Celeste carries that with her. 
So we would end up with: Size +1, Dedicated Building or Elevated (0), Basic (0), Haunted (-1).
I will select a Minor Virtue to complete the lab, if you want. Let this be a surprise when she arrives.
