I failed to mention that I also consciously note when I touch something public. I’m fine with touching anything, shaking hands, etc. I just won’t touch my face or eat food until I’ve washed my hands again.

This is what I do. I just always try avoid touching anything directly with my hands. Knee, elbow, back of wrist, foot…lots of good options if you don’t have a sleeve or something disposable available.

Edit: Sometimes there is also the discrete move of letting someone go ahead of you. Looks polite and they touch it instead.

It looks to me like the building is just on higher ground. Otherwise, damn near the same height.
