Looking at the conceptual drawing on the site, I would think they may have acquired the land by the old building where Glen kept all his boats and various other things. Other possibility(or combination of both) is they will need to rip into the mountain/hill that the old building is built on.
Only glaring error I can see in the picture is the pool. That absolutely needs to be a negative (disappearing) edge pool, at least second floor level overlooking the bay and the sunsets. Anywhere else would be a waste of effort.
