What is that ‘thingy’ on the roof?

This blog post was inspired by an article that I recently read as well as conversations I’ve had with many clients. Architects (and builders) have names for just about every component or system involved in the design and construction of a building. Most of these terms have been passed down from as far back as the ancient Egyptians to as recent as last week on Winter St, and some we make up as we go.

The author of the article claims that the smartest thing we can do as architects is to stop talking to our clients like they are architects. I vigorously disagree. To dumb down a term or a phrase implies that you are stupid and can’t begin to understand the architect’s  ‘la cosa nostra’ (or more accurately… ‘la nostra piccola cosa‘). Yes, to say to a client (as quoted from the article) “Communicative inheritance, remembered as the true conveyance of cultural integrity, fosters an exchange of the sacred geometrical building blocks.” only showcases the architect’s knowledge and/or use of big words… or simply just their arrogance. But why not teach our clients, or at least familiarize them with the archi-speak that we use in general conversations with each other and the builders we work with? Then guess what happens? Client empowerment, and most notably a trusting relationship.

The following is a quick glossary of arhi-speak terms to educate…  and maybe amuze. And like I said it’s a quick list so I may have missed one or two, but feel free to add.

Blueprints: Not a term we really use anymore, now we just call them drawings? They were called blue prints because the printing process (which involved a lot of ammonia in an under ventilated room) turned everything blue except was was drawn or written, which turned white. Blueprint paper was yellow before the printing process… no kidding.
