'no one would live in it' is the definition.
I can't tell whether this defines the answer.

'eco-friendly accommodation' is the wordplay.
'eco-friendly' becomes 'green' (green can mean good for the environment).
'accommodation' becomes 'house' ().
'green'+'house'='GREENHOUSE'

'but' acts as a link.

Can you help me to learn more?

(Other definitions for greenhouse that I've seen before include "Horticulturalists' glass building" , "associated with harmful gases" , "Glass building for rearing plants" , "A place for growing" , "see-through construction" .)

I've seen this clue in The Guardian.
