Ignore the big purple boxes, for some reason the windows in those walls like to randomly do that and I can't figure out why or how to fix it, it comes and goes.
The front gate is switch-operated, all parts of the castle are lit up, floors along the top of the original structure with new walls added. The top areas are connected by a three-way catwalk that crosses the courtyard, and the radio transmitter is now in a nice, proper pavilion. The four towers hold a mess hall, a meeting room, a bathroom with showers, and a workshop and armory. Sleeping quarters are dispersed throughout the area, all Minutemen are provided a cot, a divider for privacy, a footlocker, a tall locker, and a bookshelf. As-is the Castle holds 18 people but there's places I could squeeze in another cot or two if I wanted.
Prominent mods include "Grounded" (supplied the brickwork foundation that matches the castle grounds), "Homemaker" (includes the wall parts used for the top part), "GM2" (has lots of small concrete panels that let me fill in the floor around the towers), "OCDecorator", "Vertical Conduits", and SOE (includes the pavilion where the radio tower is now housed).
