The title card reads "Basket Castle Northeast Tower," and Basket is alone on the server, back inside the tower where the birch floors are going in. The old shovel is worn, but instead of repairing it Basket crafts a temporary one from a block of iron, since it won't see much use.
A walk down the floors
The floors are mostly birch, so that's what Basket sticks with. Down here, "this is the kitchen that we're going to make for the room upstairs," with a spot that will eventually be a window and some other room beside it. Another floor has no plans yet. It turns out to be finished already, and the stairs lead down to where Basket ran out of blocks. The next level is going to be "a little floor here with a balcony looking down."
Digging out the dirt
Below that, the inside of the tower is still packed with dirt. The shovel is slow, and there's no haste over here, but Basket wants the dirt gone before it turns into grass. Then the temporary shovel quits: "And there goes that shovel. No warning." The inventory is full too, so the loose stone gets crafted into stone bricks along with a pile Basket was already carrying.
How far down
To make room, Basket sets down a crafting table and a chest at the bottom of the dig. "Yay, all the blocks are saved. Ish." A second shovel breaks soon after, and since there isn't much dirt left, "let's skip the shovel."
The dig is almost down to ground level, though Basket "can still go down down down all the way down to Goblin Town." For now the plan is to build down to the main level, where the road around the castle will run, and maybe go deeper later for storage. A basement might connect to other structures with "secret doors into this tower." Switching the beacon to haste would have finished the job by now, Basket admits. "What's the fun in that, right? We're not in a rush." The walls get filled in where the dirt was, with other blocks to come later for texture.
Three and a half, exactly
The birch runs out, so it's back upstairs for more. The whole floor goes in first, and then Basket works out the room: a doorway, stairs going up, a balcony, and the stairs down starting against the wall. With three and a half blocks per floor, Basket counts it off. "Half one two three. Oh, look perfect. Okay, and this is the floor amazing. It's like I planned it." There was no hidden reason, it "just happened to work out." Then comes the torch spam.
One more window
Below that is the next floor down, and where its stairs go is still undecided. Basket notes "I still want to go further down" before stopping for the day. There's one last job: windows. One goes in on the next level down, "really quick as an ending," and the last look is from outside, with Basket standing in the new window between the cobblestone columns.
