That's some nice work. In my 2014 the space below the furnace is occupied by the electrical panel. I know they moved it as I've seen photos of the 2015s. I have noticed that the drawer gets warm from heat inside the cabinet. I bought a decorative grating (floor register) and plan to open a vent location on the side of the cabinet to vent the heat build-up.
The shoe storage/laundry hamper is great and something I'll have to add. I see foam insulation on some of the pipes by the water pump. Is this something you added?
