Red Rocket Overhaul
If you aren't fond of building settlements or you simply don't have the time to commit to the process, take a look at this modification for the popular Red Rocket Gas Station.
It comes with some amazing features including a movie projector, curtains, fireplaces, a warehouse for storage, a set of RVs, and a helipad. It also comes with enough space for your own modifications and decorations.
In addition, the mod features a unique lift system that takes you up to a large perch above the main buildings below. The perch features storage and it's also a great place to spot and/or pickoff enemies from a safe distance.
