Similar to the loft, I built a closet organizer thing.
This closet consists of about $95 in parts and lumber at Home Depot. Like the loft, this was built from scratch and 100% of the cutting was done in the store. They do a good job there.
I drilled a whole bunch of holes so that the shelves would be adjustable. I made sure to do a crappy job so that people would know it was handmade (yeah, that’s the ticket).
There are two closet rods, a set of 12″ deep adjustable shelves, and a set of 8″ deep shelves. The unit as a whole does not interfere with the existing door, light switch, or outlet.
