Using Tinkercad I have designs buildings to create a Railroad Town. It started in 2016 when I designed a Train Engine and related train cars. They were all based off the early train designs, when trains ran on coal and steam. Two of the building I designed for my town are, a Saloon and a Sheriff Office (a.k.a. a jail). If anyone was going to spend any time in the jail, and if the town kept growing, they would a Town Hall to provide administration.
The Town Hall often had a clock tower and consisted of numerous details. I incorporated these details by adding large columns and lots of windows.
The clock tower I frame in gold and set the time to after the start of the workday. I duplicated the clock and placed it on all four sides.
Town Halls, in the Railroad Town days, had a bell to signal the town. The building appears to be only one story, and if I put the bell in a tower, it would look out of proportion. Therefore, I placed the bell on the stone platform.
All of the buildings for the Railroad Town are based on the same scale. The doors and windows are approximately the same height. You can see and copy the 3D version at the Town Hall at this link: Town Hall. Sometimes, you learn more about how something is designed by deconstructing it.
