The Chemistry Laboratory building didn't have a requirement in particular. However, thinking logically, he couldn't just make a random building and label it as such.
After all, working with chemicals could get dangerous.
That's one of the reasons why he moved the lab's site to the edge, trying to make it safer for the others, even in the case of something bad happening—like a failed experiment, with dangerous chemical fumes spreading through the air.
"Just like with the workshop, I need good ventilation without allowing dust to enter..." He muttered as he skimmed through the Housing Panel.
However, maybe due to his low level or something, none of the available buildings fit his needs. Not willing to give up, he tried searching again, lowering his requirements a bit, but still got nothing out of it.
"...No choice!"

"I'll just modify one that's available!"
