During my recent visit to Medan Indonesia, one impression that struck me was the amazingly rich number of cottage businesses, especially along the main roads. Within a couple of blocks, you can literally find nearly any kind of consumer retail business, grocery or food stand, and even some manufacturing.
Common residential / retail home in suburban Medan. Newer buildings have newer construction techniques, but basic architecture remains the same.
