"More square feet for less dollars"
This was the slogan of a house builder I once analysed for a management consulting project on the future of the Australian building industry.
After a week touring display homes, and estimating cost (or costs avoided), I figured out exactly how the market leaders lowered the sticker price while increasing their margins. No matter that the houses quickly fell apart after purchase...
The tricks I remember included:
* No plaster on the wall behind the fridge
* Big mirrors in bathrooms, because mirrors cost about the same as tiles but are much quicker to install.
* Eliminate walls on the ground floor, to give the open-plan look. Except that there's no sound insulation, or heat retention. And the new owners need to buy a lot more furniture, otherwise it looks too empty.
* Make the eaves very narrow, to reduce the size of the roof. Even though the walls now have no shade from the sun, the interior heats up more in summer, and you spend much more on air conditioning.
* Build the house like a big box, up close to the boundary line... Looks good on the plan. Less good when your neighbours' bedroom windows look right into yours. And less good when there's no shade or privacy because the builder cut down the established trees...
I remember both feeling in awe at the cost-cutting ingenuity and disgusted at future problems it would bring the unlucky new owners.
