Making building cakes, or any scale model of anything, can be a challenge. If you don't get the proportions right the whole thing looks wonky, and for things like cars and animals that can be really off-putting visually.
I started by taking pictures of the entire building by walking around it and making sure that I got a good look at how each wall was designed. The building has overlapping sections on each wall, and each section has different heights. I needed to get a good look at how each piece related to the others. The two sides were the same, but the front and the back were different.
Once I figured out the size of the footprint that cake would have on the board, I started on what the sections of the walls should be. When that was calculated I made a checklist of how many pieces I'd need of each part so that I could make sure to get everything done.
Coming Monday: Part 2, creating the wall sections.
