The Lantallian GX-Class Executive Transport was developed during the days of the Old Republic to ferry the rich and famous throughout the galaxy. In order to ensure the high class passengers' safety, it had a spacious hyperdrive-enabled escape pod mounted to the ship's underside.
The comfort of the passengers (and appealing to their refined dispositions) was paramount in its design. As a result, the passenger and crew areas of the ship are entirely separate, removing the need for the two to interact at all.
I saw this ship in The Clone Wars cartoon and absolutely had to plan it out for a small-scale RP a couple of friends and I are playing out.
Sources claim it's a GX-1 Short Hauler (and comparing the exteriors, they look pretty similar), but established deckplans either weren't to a satisfactory scale or didn't show the same ship that was seen in the show.
Most of the design of this is based on screen captures (of which only the escape pod access, cockpit, and adjoining compartment was visible).
