Those look like totally standard "startup with long rows of desks", although lower density than I've seen elsewhere. Trying to get work done in what is essentially an aisle off of a walkway would suck.
I wish there were a list of companies somewhere which sorted them into private offices, shared offices (2-3 people), team rooms (3-15 people), high cubes, low cubes, work areas for teams in rows in bigger rooms, and "one huge room full of every desk, all in long rows".
