At Cape Town’s advertising agency Ninety9Cents, the architecture firm Inhouse put in its 2 cents—in the form of the reception area’s shipping container. It’s lined with OSB and furnished to serve as a waiting lounge for clients from the likes of Checkers and Puma. That’s all a nod not only to the harbor, seen from the windows, but also to the creative solutions the agency sends around the globe. The other major intervention is less symbolic than pragmatic. A bleacher-style structure that also houses the kitchen acts as a communication hub for the 200-strong staff, split between three office levels.
