Oleu Ffynnon

Oleu Ffynnon is a symmetrical two-storey, two-window house dating from the 18th century. It features a central entrance and has lower wings on either side; the left wing is likely a service unit, while the right serves as an outbuilding. The house is rendered and whitewashed, standing on a plinth under a shallow slate roof with rebuilt red brick end stacks. It has two-light iron-glazed windows with large panes, and shaped hoodmoulds above the lower storey openings, with the upper storey windows positioned under the eaves. The entrance consists of split doors flanked by windows. At the rear, which is partly visible, there is a tall two-light casement window in the centre of the upper storey, likely a stairlight, and a late 20th-century glazed opening below.

The lower units on either side of the house both have corrugated metal roofs. The right unit is weather-boarded and features a boarded door on the far left. The left unit is rendered and has a boarded door and an iron-glazed window, both offset to the right, with a similar window aligned above. The east gable end of the left unit has split doors offset to the right, accessible from an open-fronted garage. The rear of this unit is constructed of brick and includes a casement window in the upper storey; the lower storey is not visible. The interior has not been seen during the resurvey.
