There's a construction trailer on South MacArthur in front of Anatole Apartments along with pallets of bricks. Is something finally being built there? There's also a large warehouse style building being built across MacArthur. I'm guessing that's a spec build?

And yes, the large building just west of MacArthur on SW 13th is a spec warehouse building:
