Description

Bron Heulog is a three-unit baffle-entry house featuring a rear lateral staircase located within a gabled turret that wraps around the oven extending from the main fireplace. A later wing has been added to the north side, east of the staircase turret. The building is constructed of rendered stone and topped with an artificial slate roof, featuring a double mid-chimney made of stone.

The front of the house has four modern dormer windows, three of which align above modern downstairs windows, all of which are of the mullion and transom type with small panes. The main door on the south elevation has wrought iron hinges and is studded with nails. There is a side door on the east side, which is not original, featuring a small rectangular overlight and a gabled hood. Access to the main door is via four steps, with additional steps leading to the side door.

The house is situated on a very tall terrace above the level of the farmyard, where a brick-vaulted well is integrated into the retaining wall. The layout is of the lobby entry type, with a larger fireplace facing east in the main room and an oven to its right. A door to the right leads to the staircase, which has a shaped handrail supported by small turned balusters. A smaller fireplace is reported to be on the left, with a closet located beneath the stairs.
