Mid-to-late 18th century, in the "gothick" style according to the listing. I approve of their spelling. This is definitely the right listing, as here's exactly what we see:
Symmetrical end has an elaborate Dutch gable with a 2-centred arched doorway with panelled door, and matching windows each side with lattice leaded lights. Above is a tripartite window with 2-centred arched heads, central casement with interlacing upper glazing bars and blind outer ones.
