According to Cadw, Bron Edda is 'located at the south east edge of the town on a hillside, backing onto the Coed y Wern; at the end of a short lane leading south from the Pont-y-Pandy.'
It is 'one of a number of Gwydir estate cottages built by Lord Willoughby de Eresby c.1845 and conceived in a characteristic and highly stylised pseudo-vernacular style. This estate style represents a fusion between the Tudorbethan popularly employed in this context, and a Picturesque historicising style, ultimately dependant on such earlier examples as the Ty-Hyll, or `Ugly House' near Capel Curig.'
Bron Edda is a 'single-storey 2-window cottage constructed of rough-dressed slate-stone blocks under a slate roof. This has deep verges and eaves, the latter with characteristic shaped corbelling, diagonally-set at the corners, and the former of large slate slab construction. Round, projecting end chimney to the north gable; of 2 stages with a cylindrical stack also of 2 stages, smaller at the top and with plain cornices. Near-centre entrance with slightly-recessed boarded door; modern flanking leaded, wooden mullioned windows with projecting slate cills. Triangular arched-headed window to south gable; plain glazing.'
Grade II listed because it is 'a mid nineteenth century estate cottage of characteristic design.'
