Re: slow it down and add costs
as for cost, they cant get into that sort of thing for a few reasons, the first being they are constantly using brand new products which arent out on the market yet.
2) labour rates vary from region to region and company to company. same goes for material costs
as for showing how to do something, its extremely difficult to do such a thing when these projects take place over many months and thye only have 22 minutes a week to document whats been going on at that specific house
