Not really. In the US you can get standard 92-5/8 and 104-5/8 studs, this is the correct length for 8 and 9 foot walls, you can get a house built with any other size walls if you want but it will cost extra. The drywall comes in panels that will fit (4 foot, the other is 4'6). Doors come in standard sizes widths in 2 inch increments, but they all have a standard height. (bi-fold doors have a slightly different set of standard sizes). There is of course some material that needs to be custom fit on the way, but most of the material is already pre-sized.
This is innovation that has already happened and taken a lot of time away from what is needed to build a house. If you want to innovate, you have to innovate on top of what has already been done.
