This seems more like an example of procrastination not technical debt. Technical debt as I understand it requires a previous decision to impeed new decisions/progress because it wasn't done properly the first time.

A better example would be he wants to add a brick chimney to the roof but can't because the roof is made of straw thatch and can't support the weight, so it would need to be rebuilt first out of timber, and then a chimmney can be added.
