  • The lab is clearly dimensional-transcendental, meaning its bigger on the inside. Numerous times, the lab has been destroyed, only for a small portion of the house to be gone. This suggests the lab exists in another dimension.
    • This makes it similar to the T.A.R.D.I.S. from Doctor Who.
    • Lab of the Lost implies once Dexter runs out of space, he creates more as he doesn't know the abandoned part of the lab well.
