Bryn-y-Parc is a complex arrangement of sub-medieval structures, some timber-framed, some stone-built, which form a court-yard plan, fronting Park Street, close by the late-medieval market square. Its development is unclear at present. However the buildings appear to have developed mostly from the mid 16th century, culminating in the c.1870 vernacular framed finish to the south and east garden facades. Its early 17th century timber and stone built front range has a lateral fireplace, indicating a building formerly of high-status and the panelling to the rear 2-storey parlour/hall and principal-chamber unit confirm this impression.

The present front-range retains the line of a late 16th century cross-passage between hall with lateral fireplace and parlour, which leads into a courtyard. This passage (later enclosed) continues across the courtyard alongside the timber-framed, 16th century, 2-bay wing, past the late 16th century, stone-built, parlour/hall and principal chamber block, to the formerly detached 16th century, stone and timber-framed 3-bay kitchen/lodgings range. The passage continues through this building to access the 17th century, stone-built, stable-range and garden beyond.

An entry passage against the west boundary wall provided separate and later access to the 16th century, kitchen/lodgings range beyond the courtyard.

Photographs taken of panelling prior to the fire inside the 2-storey parlour/hall and principal chamber unit, include a carving of the Annunciation with inscriptions and the arms of the Lloyds of Foxhall.
