If your game is taking place in around the year 1105 Imperial, remember that anything pre-Maghiz is more or less 2000 years old or more (IIRC). If the station hasn't been crewed for two millennia, but has been abandoned all this time, it's going to be look more like a tomb than a research station. Any gardens and greenhouses have either run wild (if its a closed system) or been dead for a loooong time. Most systems are likely to not function very well if at all - missing the past 2000+ years of maintenance is going to leave its mark even with that TL16+ tech. Any maintenance robots ought to have broken down by now. Of course you can assume some high tech self-repairing and replicating bots, but I'm not sure if those fit Traveller that well. Even the power generator/reactor might no longer function (at the very least be shut down if/when the station was abandoned), it would suit the mood well, if you're looking for an eerie ghost station vibe.
Of course you can ignore all that and just assume TL16+ tech goes on practically forever, even if abandoned, and let everything be just like it was 2000+ years ago.
I've always envisioned Darrians as kinda-sorta Vulcans (of Star Trek) and using their symbology and style could give you inspiration in designing the station. Also the 'orchard' style could be interesting, with organic shapes and designs in even technical devices (rounded instead of hard angles etc.), maybe even using a lot of organic paneling in rooms, etc.
