I understand the basic concept of scratch building and I can build the basic shapes using basswood etc..
However..How tall should a building be so that it is scale height and length?
Where I get hung up is on the detailing part and finding where to get the different types of sidings/windows/lights/railings/steps
All of that is what makes it a great model but where can one find these various supplies?
My next project is a trackside brick warehouse with a RR loading dock and I understand how to build the structure but where do I go from there?
here is an example of what I want to create:

Thanks!
