Recently I've thought, that if we are able to buy a base (that obviously was built by someone) then why not to add an ability to build it? But since the engine doesn't support the dynamic maps, there could be another way out. So I suggest to add a recipe (which is in a fact a 6 recipes) that could be obtained by buying a scheme(s), for a very little amount of caps (let's say 500 or 1000 in most of the towns) or available to get via quest. This is how it works:
The player gets a scheme (no matter how he did it - bought, get as a reward or stole it) that adds to his Fix Boy a new recipe. But as it's not that easy to build something big, it would require a collecting following materials:
To build a cave: 3x (http://www.fo2238.fodev.net/wiki/images/3/31/Axe.gif); 1x (http://www.fo2238.fodev.net/wiki/images/1/17/Oknife.gif); 2x (http://www.fo2238.fodev.net/wiki/images/f/f7/Rope.gif); 2x (http://www.fo2238.fodev.net/wiki/images/4/4e/Flare.gif); 3x (http://www.fo2238.fodev.net/wiki/images/3/38/Pump2.gif); 5x (http://www.fo2238.fodev.net/wiki/images/9/99/Metal_trash.gif); 10x (http://www.fo2238.fodev.net/wiki/images/3/3f/Grenadeo.gif); 4x (http://www.fo2238.fodev.net/wiki/images/a/ac/Firewood.gif); 10x (http://www.fo2238.fodev.net/wiki/images/4/47/Brahmin_skin.gif); 3x (http://www.fo2238.fodev.net/wiki/images/b/b5/V15comp.gif)

Every part could be crafted independently, so the player would be able to craft these parts one-by-one and there will no problem with the weight capacity. Also, after crafting of each part, it should become weightless of its weight have to be reduced by 10 or so, because otherwise it would lead to the creation of the alts, which isn't good for the gameplay.
Since it gives a chance to get a faction base for the lone players and the beginner factions, these factions (players) should be able to buy a faction name after they have built a base from the same guy, that has sold them a scheme. But if they don't want to have a name, they can use the base without of it (this way they wouldn't have a chance to participate in Town Control)
It shouldn't be a big deal to implement this, since adding a new recipe doesn't take much time normally.
