ABC’s of Architectural Millwork

Remember the game telephone? Someone thinks of a sentence, then whispers it to the next person, who whispers it to the next. The design process also passes through several stages, only in this game the players are the client, the designer and the carpenter, and if you are not careful, your vision can end up as discombobulated as that message you tried to pass in the game.

Communicating design does take time, no doubt about it. But it will save a lot more time by reducing the backlash that occurs when craftspeople don’t have a clear understanding of what it is they are supposed to build. Using technical language can greatly limit confusion, especially if supported visually with CADs or sketches. Here are some architecture and design terms that are useful to know:
