Having made a short visit while passing by, comparing what's mapped and/or appears in imagery versus reality, the whole area has changed and will need to be reworked.

Imagery which is definitely outdated: Bing, Esri World Imagery (Clarity) Beta.
Imagery which appears to have been captured since (most of) the (major) changes (and thus closely matches what's now on-the-ground): Mapbox, Esri World Imagery [regular, not ‘(Clarity) Beta’].

The structures (sheds / greenhouses) between the two parking areas have been removed and replaced with parking, the SW parking area is now a fenced-off staff-only area (& (customer) collection point at the gate). There's a few newer structures, also (not shown in any imagery).

The parking isn't simply an open area; there are modular metal barriers laying out parking aisles & rows. Plus trolley bays & (emergency) assembly point.
