Just be aware. That's a lie.
Every single one of the plots have beds for settlers. The fact that it doesn't look like a bed doesn't make it any less of a bed.
And if the poster is not happy with these looks, then by all means he can use any of the other addons that add 16 different and themed residential 1x1 plots. Or make his own addon that adds 1x1 residentials.
Sorry, dude, I didn't mean to step on your chops. I also went looking for small internal beds and found Apocalyptic Additions, but for my style of play, the residentials mostly don't fit. Call of Duty works well in a bastion at the Castle, say, 3 to a long wall -- but that level 3 board at the base of the bed kills it for something like a utility room in Sanctuary. I really like Writer, a sensible room for a sensible citizen in a recovering Commonwealth, and I use Espionage a lot as well, though I delete the brick wall that tends to stick thru ceilings. The Brotherhood of Steel one, Patriot?, is nice, but I forced myself to do a BoS playthru only once, long ago, to make sure I still didn't like the sons-of-bitches, so I've not yet actually used it in a settlement. The others...not my thing. The Martial plots, on the other hand...I use several of them on a regular basis.
Yeah, I've been working my way thru kg's tutorials, specifically looking to build interior residentials/leisures that fit into spaces that actually exist in the Commonwealth, like the Utility room in the Sanctuary houses, and those 1-and-a-quarter spaces in the castle, or that wide-enough but not deep-enough space at Taffington Boathouse, by the opening to the kitchen. I like building things, that's why I'm still playing this game, after all.
So, you've had some experience building SS2 plots, yes? I've yet to attempt a Martial plot, but I really need Minuteman Artillery that I can actually assign someone to, where they don't wander away as soon as I leave. It is...deep breath...very annoying. There were a couple available in SS1, not yet ported to SS2 that I can find, so I thought I'd try my hand at it in the mean time. Is it hard to get an artillery piece on an SS2 plot to interact with the smoke grenades, do you know?
