TechnicalRegister
A building delivered with only its structure, envelope, and main services complete, leaving interiors for the occupier to finish.
The developer handed over the offices as shell and core, so each tenant could fit out to its own specification.
Rarity runs from 0 (a word everyone knows) to 100 (almost never seen outside specialist or literary writing). Level is the word's real difficulty on the CEFR scale, from A1 to C2.
