More Building, Digging... and a Rock

I was away for a week, but things kept moving nicely at the worksite.  The second floor is in, and work should move to adding the roof in the next few weeks.

They are also excavating a space in the garden where the bathrooms will be.

Unfortunately (but not entirely surprising) they ran into some rocky earth.  Digging with jackhammers is very slow going, backbreaking work.  you can see an outline of the rock in the picture below.  The soil above is darker, with roots, and below the whitish area is the result of pulverizing the granite stone.
