If I ever get the opportuinty to design my dream home, I would like it to have a flat roof. I like the look of hard shapes, and I also place importance on standing out from the crowd. I was wondering about the pros and cons of such a residence. I understand that large buildings such as a walmart would need a flat roof for obvious reasons, but even small buildings like gas stations have them. Is there any financial advantage to either? heating costs? maintainace? materials?

I'm writing an essay about my visit to Tijuana, and I'm not sure how to describe the buildings. Not the buildings among the main street, but the ones more in the side areas where there were little vendors set up and the streets were all dusty and all the beggars were. Right now I've described them as clay brick. Is this right or is there a better way? Stucco perhaps?

I know that outside federal buildings, or even off federal property (ie: across the street from the building on the sidewalk), there have been issues about people being detained or questioned by authorities, or even Law Enforcement for photographing federal buildings, even from public property. I don't know what the rules are. What even gives security guards in federal buildings the right to enforce photography restrictions off federal property? How far way from the property do you have to be?

I work in a listed buildings and would like to find out the history of the building and get old photos if possible.
