I noticed the very moderate goals set by this builder. 1/2 the time to build the house is great, yes! But 80% of the cost seems... good enough for this year? when it's all they can foresee. As mentioned elsewhere this is in spite of progress in materials and skills needed to install them - and these savings benefit both built-on-site and factory-built. I can see how cutting down on the number of alternate codes would cut down on the cost of engineering in these houses. And perhaps help realize economies of scale. Something not mentioned in this article is that a development with 30-200 units should help on economies of scale but at the same time I can see how it doesn't: Such developments around here always include a lot of differences from unit to unit - perhaps necessary to get the project approved or reach an optimal profit on the finished houses.
