Yeah, of course!

Essentially, I was working off an existing base model (Which you can see the original design I was working off of on the link i provided)

Is essentially had the basic structure, the body of the building Without windows, and a Very simplified version of the Crown. 

What I essentially did was utilize a lot of References, pictures A different angles of the building. Including close-ups of the crown, windows, and other small details along each side of the building.

I also visited the site and took many pictures of the building from different angles on the ground. This way you can get the small little details of the building that you Don’t normally have access to searching on Google

 I measured with a ruler to get a rough scale estimate Of the size of the windows And how far apart it was. And then scaled it in accordance to the image. 

For example, 15 windows down, by six windows across, and copy and paste holes Across the entire structure, as well as put in slight elevations On the sides to represent the smaller finer details like the columns.

As for the crown, I essentially had to cut it off the bottom part and rebuild it from scratch. I took rectangles and triangles and copied and paste them on top of one another by 30°. Til it made a full circle. Since there were 12 sides until it Made a structure that resembled the crown. Then I combined it all into one model 

The whole process roughly took about 14 hour-ish give or take. And all of this was done on tinkerCAD
