    So, it doesn't actually exist?

    When I built my house, 15 years ago, I had already put down a deposit on the "kit" for the main structure, but I needed a way to build the daylight basement for it to sit on. I found these styrofoam concrete forms:

    Once you learn the system, it is ludicrously simple. You just stack them up like big lego blocks and snap in the rebar. Then you call the concrete trucks to come fill them up. The only tricky part is bracing everything to stay straight and true while the concrete sets. (You have to rent special scaffolding.) If I had known about this stuff before, I would have built the whole house from it. (One house in town was subsequently built entirely this way.) Basically one or two guys with about four tools can do a large house in a couple of weekends. The walls are equivalent to R50 insulation. Exterior siding screws on to the outside of those plastic cross-webs. Drywall screws to the inside of it.

    No zillion-dollar robots needed.

The house was auctioned off with proceeds to be donated to the City of Palm Beach Gardens for a municipal swimming pool. This was believed to be a world record-breaking construction, beating a previous record of 19 hours held by U.S. Homes Corp. The average house normally takes about three months to complete, according to an experienced home builder
