For bad quality house built or bought-Whom should we blame?

If there is a house built,completely finished in all aspects where you simply have to move in with your personal belongings,it will be too good.
If that villa happens to meet all your requirements for the house,it will be good
If the house has the best design with professional involvement,good structural design,good workmanship,best materials used for each and every component of the house,it will be almost a dream come true.
But in reality such a dream never happens.Who build houses and sells?People who want to make money building and selling houses.If you do everything about house built correctly with the best design,best quality of materials and labour,may be you as a builder may not be able to compete in the market as your competitors are not much bothered about quality of work.When they offer a lower price,potential client who may not be able to judge superior quality of your work or design will naturally buy lower priced house.
So builder is left with no other alternative other than making compromises at least in areas where lower quality of work cannot be easily noticed.
Even when you are willing to build your house directly from the beginning with development of design,you look for cheaper alternatives.Rather than searching for the more capable designer with better creative talent,you look for some one who can draw plan of house free or with nominal fee.Then you search for a building contractor who quote lowest “square feet cost “knowing very well that the final cost may not necessarily be limited to that figure.
So when you buy a villa or when you construct a house with direct involvement,you are not keen on getting the best.When you really want the best(of course within your budget limitations),you will be willing to take professional guidance and assistance.Fees payable to a professional do not necessarily pull you back to have the house with many compromises on every aspect of construction.
At least you should not simply blame builder in either case.If builders are making compromises it is due to you forcing them to make compromises to remain in business.If you are willing to pay right price for the right quality,things will start improving on both ready built houses and custom built houses.
