Nice little project. My contact added a rough sketch to the briefing. A supply chain starting with a Manufactory over to a Warehouse and finally a Retail Shop.
first sketch proposal
I prefer one contact over the course of a project. Having to work with several contacts adds to the complexity of a project and usually slows everything down.
colour branding
The final illustrations had to be black and white. This is a test using the clients' brand colours. They specifically asked me to leave out people because this would involve handling actions and therefore could deflect the viewers attention from the supply chain.
The dimensions of the structure are the same for all three applications. The same goes for the delivery / exit gates. Only the roof tops hint the structures' specific function.
