Yes, this is the preferred approach.
General Scale has an effect only at the size of dimension components like text and arrows. You can leave it set to 1. But then you have to correct (enlarge) all the values according to the intended printing scale one by one. Better set General Scale to the inverted value of the printing scale. For example if you want to get your 60x100 feet house onto an A4 or letter sheet, you will need a scale of 1/8''=1' equivalent to 1/96. So set General Scale to 96 and you can leave the other settings in Dimensions as they are out of the box (the true size on paper).
It's best to work in inches for this example. Here is a sample drawing for letter and 1/96 I once have made. You may study the settings. arch_inch_1_96_letter.dxf
