This stream runs about 63 minutes. It opens on a card reading "Hypermine Vanilla VOD" and "Basket Station Second Floor" with no episode number, so the number here comes from the playlist. Last time the first row of stores went up in polished andesite with a granite stripe. This time Basket builds on top of them. Basket is the only player on screen.
A floor three blocks thick
The second floor has to be three blocks thick. Basket wants the same sunken lights as the quartz walkway below, a lamp under glass with a lever beside it, and those need room. A lamp in that layer could even have glass on both sides and light the store underneath too.
Getting up there means climbing, so the beacon gets covered over for now and a few temporary steps go in. Those don't last long. "Here, I got an idea, check this out. Instead of trying to build stairs all the time," Basket hangs ladders on the wall instead. Then the floor goes down over the stores, with torches everywhere in the meantime. "I don't want any spiders making noise."
A walkway with a view
Along the open side, the upper floor sticks out three blocks with a fence on the edge, which leaves "two and a half" blocks to walk on. Where there isn't room for stores, Basket decides the space can be a commons area to look out from, maybe with a bridge across one day. A viewer asks about the stairs up, and Basket confirms they'll be quartz stairs, partly because none of the stone blocks used here come in stair form.
Then the old wall by the rail line comes down and goes back up in the new pattern, granite along the bottom and andesite above. Basket has to be careful here. The destination picker buttons sit on those blocks, a few ladders go missing, and the powered rails have to go back in. One stretch can't change shape at all: it "needs to remain flat because the carts come down from the roof and meet up with it."
Stepping out the overhang
With no stairs for these blocks, the edge of the upper floor can't slope. Basket steps each row out one block past the last instead, "more of an arc." Partway through Basket figures out the off hand: right-click with a block there and it goes in place. "Okay, there we go. It's kind of cool."
From below it looks odd, so Basket tries making every other row granite to tie it to the stripe on the walls. That means building scaffolding up from the ground to reach. Seen from the floor, it works. "Yeah, I like that better than with it without that."
Pistons for the openings
The stepped section has openings in it for the carts, and Basket would rather they weren't open holes all the time. The new plan is to close them, then open them when a cart comes through. Basket grabs sticky pistons, detector rails, repeaters and redstone from the storeroom and starts testing: a sticky piston to move the block, a detector rail to sense the cart, a powered rail that has to stay powered by default. Even better, a cart on any one of them could open them all at once.
It runs into trouble fast. "You can't have rail on top of an extended piston." The fix is to drop the whole section down one block, which Basket says will happen off camera. The newest idea is for a piston to push up a redstone block that powers a line running over every opening. "This may have suddenly become a much more intense project for this time slot."
Building done, redstone not
The stream ends with the hatches unfinished. Basket sums it up: "we did some building stuff and then we did some complicated unfinished redstone stuff." The mall feels much closer to done, though it isn't there yet. The credits run to the end with no gameplay after them.
