grange

'farmhouse' is the definition.
(I've seen this before)

'good to roam freely' is the wordplay.
'good' becomes 'g' (abbreviation).
'to' says to put letters next to each other.
'roam freely' becomes 'range' (synonyms. I am not sure about the 'freely' bit.).
'g'+'range'='GRANGE'

'reaching' acts as a link.

Can you help me to learn more?

(Other definitions for grange that I've seen before include "old dwelling" , "US lodge" , "Country house with outbuildings" , "Country-house" , "Ganger in country house with farm buildings" .)
