Very nice and the price is good, too. As they're quite simple, they could be used for a lot of things, instead of pre-fab slum they remind me of pre-fab field offices. Have you considered making an accessory set for more diversity? A comm dish and/or an antenna array would easily turn these into communication sites, for example. A ladder and a roof hatch would add some nice detail. A set of barricades you could line the roof with would turn these into small guard posts...you get the idea. Great job on these!
