Builder: Mission has started.

Builder: hello

Architect: hello

Architect: begin by placing 2 yellow blocks flat on the ground.

Architect: place them near the center

Builder: place yellow 0 1 0, place yellow -1 1 0

Builder: is this ok?

Architect: yes

Architect: now place 2 more blocks vertically on top of the yellow block on the right

Builder: place yellow -1 2 0, place yellow -1 3 0

Builder: inverse L?

Architect: yeah

Architect: it's an inverse L.

Architect: perfect.

Architect: Now 2 more blocks to the right of the 2 blocks you just placed

Builder: place yellow -2 3 0, place yellow -3 3 0

Builder: like this?

Architect: yeah that's fine.

Architect: place 1 block in the corner

Architect: the corner that isn't the L

Architect: this structure is completely 2 dimensional

Builder: oh

Builder: in the intersection..

Builder: place yellow -2 2 0

Builder: here?

Architect: place 2 more blocks.

Architect: 1 above the middle highest yellow,

Architect: one above the right highest yellow

Builder: place yellow -2 4 0, place yellow -2 1 0

Builder: like this?

Architect: remove that last block

Builder: place yellow -2 1 -1, pick yellow -2 1 -1, pick yellow -2 1 0

Architect: so you see that yellow block that's the highest?

Architect: place a block to the right of it

Builder: place yellow -3 4 0

Architect: we're only building up from this point

Architect: so don't worry about blocks undernearth

Builder: here?

Builder: ok

Architect: now switch to purple.

Architect: looking at the structure,

Architect: place 4 purple blocks each above the two highest yellow blocks.

Architect: 8 purple blocks total

Builder: two towers?

Architect: yes

Builder: of four blocks?

Builder: place purple -2 5 0, place purple -2 6 0, place purple -2 7 0, place purple -2 8 0, place purple -3 5 0, place purple -3 6 0, place purple -3 7 0, place purple -3 8 0

Builder: like this?

Architect: place 2 more towers at the same elevation of the purple structure.

Architect: 3 blocks tall this time instead of 2

Architect: on the side

Builder: which side?

Architect: the sides of the purple structure

Builder: oh

Builder: so 4x4?

Architect: yeah

Architect: so like make a 4 by 4

Architect: but without the top left and top right corner blocks

Builder: place purple -4 5 0, place purple -4 6 0, place purple -4 7 0, place purple -1 7 0, place purple -1 6 0, place purple -1 5 0

Builder: here?

Architect: yeah

Architect: it works.

Architect: 2 more purple blocks left

Architect: place 1 5 spaces above the left most yellow blocks

Architect: left-most yellow block*

Builder: pick purple -1 5 0, place purple -1 5 0, place purple 0 5 0, place purple 1 5 0, place purple 0 5 -1, pick purple 0 5 -1, pick purple 0 5 0, place purple 0 6 0, pick purple 1 5 0

Builder: here?

Architect: that last block you placed is perfect

Builder: pick purple 0 6 0, place purple 0 6 0
