Looks like bunkers with typical herring bone drainage, standard. What do you mean by space between?
There are three on the right, and two on the left, and what looks like a lot of space in between them. Not enough for a fairway, so I thought maybe they were two sets of bunkers for two holes, and it would just be rough in between? Maybe one hole goes up and one hole goes down?
I thought they were bunkers (drains for bunkers), but the arrangement seemed odd to me.
