It was a lower tier with a drain in the middle of the landing for the hot tub. As with most hot tubs you need to be gain access inside via the side panels. Thus the reason for the trex decking border around the perimeter. The trex has a hidden lift handle, lift them out and access the hot tub for maintenance. If you had pushed the hot tub tight against the paver landing step you'd never be able to gain access. They didn't want an additional step down there that would cause a hazard so that's why we did it this way. Seemed to turn out okay.
