I am in the final stages of my first scratch built structure. It is a switch tower modeled after the former Niles Tower in Fremont, CA.
I used a plastic core covered with basswood siding. The stairs and windows are also scratch built. The roof is construction paper to simulate shingles.
The next step would be to add a few more details and do some light weathering. Then it is ready to be installed on the layout.
Comments welcome.
