Thanks skeeter!
Concrete houses, now ya got me thinking maybe ya could try scale Structural Insulated Panels?

I'm not going to pretend they'll be as strong or even make any claims about being durable, but they will be cheaper and easier than just about anything. The boards are known to warp or curl if they get too wet. Its paper over foam so make sure your crew gets paid, or that you're there to film the Killdozer action!

It's simply a stack of foamboard (DollarTree), some hotglue(cheapest gun at Lowes). Then just attack it using a snapknife (harborfreight free), straight edge, square, and a childlike concept of what buildings look like. Clear plastic packing trash for windows, if ya get around to it. I wouldn't even worry about trying for properly scaled, a 2,000 sqft house is over 142sqft!

They make White or Black boards. I was thinking about trying some contact paper over the outsides, or lightly drawing on masonry lines, siding lines... i dunno, it's your world, do whatever feels right. Build 2 because everybody needs a friend. Maybe it needs happy clouds.

If you want a city in a hurry, have all the supplies ready to go for a build day. Make the pnwste guys build one while they charge batteries.

For a Single story building scale is pretty easy, hold it like a landscape picture, measure 1/2 top to bottom, cut. If ya like 2 story building, it's ready to rock. Measure a real door, or scale it to action figures.
I like to score & snap like drywall, but if you have a good cutting mat then several cuts through is cleaner but slightly harder on blades. I've been throwing corner braces in for strength and it helps hold angles until the glue sets. Corner braces also help locate flat roofs, and especially add strength if you don't bother with a floor and want to keep the roof removable.

The foam plane builders have a TON of build tricks to steal. You can do cool stuff with them like back-cut both insides of corners at 45 deg so there's no seam on outside. Blunted knife tip keeps you from cutting bottom paper. Peel 1 side paper off for making it into complex curves. The more you can box or triangulate, the stronger it gets.

Part of my idea was from another thread where Frank mentioned having a really cool automated cutting machine that could possibly quickly knock out buildings in hardboard or 1/4" ply. So i make a couple quick&dirty things to test scale, then maybe see if he'd like to fabricate per example...

Hoping to get to show off the suprise 'special feature' of the house next week. (Yeah, why are there switches on that thing anyway?)
