@ossobuco,
If my memory serves, the extension of the church into the next block is probably where they will build the "new" subway station in addition to the "main" entrance to Sagrada Famalia.
I remember taking a picture of the subway station on the same block as the church on the left side, but the new extension will be on the right side of the church. I tried to find the picture I took, but couldn't locate it.
