Building slots question - how to unlock without City Districts?

[MeniliteZ]

I've been spamming City Districts to unlock Building Slots on planets but then I saw in a video a point where a guy had 8 building slots unlocked with only 1 City District built. And his capital building wasn't even fully upgraded.

How could that be?

Here's the point in the video if anyone's interested:

I've done a lot of tech. I've only seen 2 that unlocked 1 slot each. That leaves 4 slots unaccounted for.

Also, the wiki doesn't list many techs that unlock slots.

Okay, I've determined he must have the Masterful Crafters civic with those 6 Industrial Districts providing 2 slots. So maybe he has capital upgraded some but not all.

Dang that looks like an awesome Civic.

Fractal seed decision. You get those from a certain astral rift. You are getting nine of these seeds, and every time you consume one of them per planetary decision, you unlock another building slot on that planet.

Other than that, there is (as stated above) tech, certain civics, such as functional archtecture, masterful crafters or agrarian idyll. Also the resort world colony type has all the buildings unlocked right from the start.

Eh? My Resorts don't have the buildings unlocked at the start!

Thanks for the other info though.
