Folk work in wood hut, ultimately, next to defensive mound (5,3)

'folk work in wood' is the definition.
I don't know anything about this answer so I cannot tell whether it can be defined by this definition.

'hut ultimately next to defensive mound' is the wordplay.
'ultimately' suggests the final letters.
'next to' means one lot of letters go next to another.
'defensive mound' becomes 'rampart' (I've seen this before).
The final letter of 'hut' is 't'.
't'+'rampart'='TRAMP ART'

Can you help me to learn more?
