Yes they do but that is because that is what you dumbasses want. I learned my lesson after building my first two. That if you really cant see it then they wont pay for it. Even if they are told what it has that others dont have then it still does not matter. Tell some dumbass that this house has 6" exterior walls and he does not get it. Tell him the house is wired with many plugs, top hot all the time, the bottom are on a switch and there are 3 switch sets on 3 ways and one switch set that ARE ON A 4 WAY, he says, SO. Show him the trim that is made with a hardwood and is finished with a poly coat, he says, who cares. Yes that is until he is paying his huge electric/gas bills, stubs a toe going to turn on a lamp, or has to walk down a dark hallway to turn off the stair/hallway lights, or 2 years later when the house starts to settle and the wood starts to dry out he sees the chaulk tear apart the huge seems (because it was pine and then panted they could cover up the crappy craftmanship using paint and chaulk).
The moral of that is, if it is your house, build it the way I used to for others. If you are building it for someone else then do it the Pulte way it is the only way you can make a living at it. Most are not willing to pay for things they dont understand and an extra 10 dollars here or an extra 50 dollars there will kill you when you have to sell yours for the same as the Pulte (and EVERY OTHER BUILDERS) house down the street. Quality cost and and most dont want to pay for it.
P.S. 3 way is a light that can be turned off/on by 2 different switches. 4 way is a light that can be turned off/on by 3 switches. I doubt very many people have even seen one, much less have one in there house. It cost 20 to 30 dollars per switch (3 are needed to make one set) compared to a normal switch that runs 59 cents (prices are when I was building).
