Q: Housing? A: Infill.

The exam is beyond ridiculous. Jobbing architects know that the process is as important than the product. Sometimes more so. And nowhere is this more evident than in the missing middle: inserting infill housing into existing suburbs runs the full gauntlet: difficult sites, unrealistic clients, negative Councils, activist NIMBYs, and reluctant banks. It’s a hard slog, mostly well rewarded, occasionally not..
