C16-C17. Hafodarthen consists of a pair of ‘unit’ farmhouses set at right angles to one another. The W house is earliest, possibly with C16 origins as a hall house: evidence of this, according to the R.C.A.H.M.W., is shown in the N gable and lateral walls, which have been raised, and slight structural signs suggesting that the central chimney is an insertion. This house was remodelled to form a chimney-passage plan with unheated inner room and downslope byre c1600, most probably when the E house was built. E house had chimney entry plan, with heated inner parlour. Both houses were eventually connected via a small lobby. Renovated after 1984, when partly derelict. During renovations, a large C18 cowshed abutting the W house was demolished, and the entry to the W house formed within the hall itself, the byre converted to a kitchen. Owned in 1843 by David Phillips, and occupied by Thomas Morgan, the tithe survey showing the farm at 67 acres (27 hectares).


Rubble construction, rendered to N and E (including E house); S gable is whitewashed. Slate roofs. Renewed stone chimneys to centre of W house, and W gable of E house. Velux window to centre of roof of W house, also to rear. W house has five bay lofted elevation. To left is window: door: window, and towards right end, two casements: all windows to both houses replaced in C20, but some protect C17 glazing, such as the N attic gable window, which has diamond mullions. S gable has attic window. E elevation of W house has intermediate lobby between both houses to right; two casement window to left with Velux in roof above. S (front) elevation of E house of two bays with casements to ground floor and two C20 dormer windows above. Junction building has lower ridgeline, with outshut porch having steep catslide roof; dormer above. Rear of E house has small window towards centre, two Velux lights above.


W house originally had chimney passage, with downslope byre, latter now converted to a kitchen, the entry now laterally into the hall. Unheated inner room at N end divided room hall by a post-and-panel partition, which has stop-chamfered posts and chamfered Tudor-arched outer doors, the E one blocked. Hall has close-set beams with deep chamfers and slightly ogee stops. Fireplace has timber bressumer, the flue reversed for stove in kitchen. Chimney stair to left of fireplace entered via timber Tudor-arched door. Tudor-arched doorway from hall into former byre (kitchen). Roof structure of W house consists of upper crucks with notched lapped collars; three sets of trenched purlins. E house consists of hall and similarly-sized parlour, both heated. Closely-spaced joist beams with deep chamfers and stops. Post-and-panel partition with Tudor-arched head to N: like those in the other house, the posts have stops set high up. Chimney stair to right of fireplace.
