"What is my architect saying?" - Architectural jargon busted

From doctors to engineers, they all use slang, abbreviations and terminology that can seem like a foreign language to those people outside their professional circle. Architects are no different and can often be heard waxing lyrical about architectural articulation, facades and fenestration. Or maybe they are talking about the implications on the DPC in relation to the DPM and FFL. If you’re a regular human being you’re probably wondering… “What does it all mean?!”.

If you are employing an architect, just remember that a substantial number of the words that are coming out of their mouth can probably be replaced by simpler alternatives that would be more easily understandable for a lay person. Don’t be afraid to ask the architect to avoid using jargon and abbreviations. Ultimately, you are the client and are paying for the architectural service, therefore it is vital that you understand what your architect is talking about!
