Exterior
The house is built across a sloping site and is double-fronted of 2 storeys, built of rubble stone and brick walls, under a slate roof with brick external stack to the L, end stack to the R. The front is brick on a rubble stone sill, painted black and white in the C20 but with a plat band between storeys, and heightening in timber framing. The central replacement half-lit panel door is within a gabled portico, which has wooden Tuscan posts. The posts are said to have been made at Ty Coch for the first Caersws Baptist chapel – and salvaged when the chapel was rebuilt in 1887. Windows are early C20 wood-framed casements replaced in mainly original openings. In the lower storey they have segmental heads but lower L the window it is a 3-light C20 insertion. Upper storey windows are 2-light, beneath the eaves, and there is a small window inserted centrally in the later C20. In the L gable end is a lean-to brick bakehouse. The wall is rubble stone in the lower storey but brick above. The rear is also built of rubble stone, painted white. It has replacement windows which are under segmental heads R and L in the lower storey, but under wooden lintels to the central stair window and inserted window upper L, which is at the level of the original eaves.
In line on the R side of the house is a 2-bay lofted farm range, although only the L-hand bay is integral with the house. This range has a weatherboarded front, weatherboarded and corrugated-iron gable end, and rendered brick rear wall, all under a steep slate roof. In the front wall are two former iron-frame lunette windows combined to create a circular window, said to have been salvaged from Caersws Baptist Chapel. Above it is a boarded loading door. In the gable end is a weatherboarded lean-to, boarded door and small-pane window. The rear is of less interest, with 2 doors and 2 windows, of which the L-hand opened to a feed passage, and loft opening.
The sawmill is built on a sloping site and is founded on a rubble-stone sill. It is mainly of corrugated-iron over a light timber frame, but the east wall facing the house is rendered brickwork, under a corrugated-iron roof. In the east wall are 3 large windows lighting work benches inside, with 4- and 5-light small-pane glazing, and double boarded doors on the L side. At the R end is a small-pane window lighting the stock room and boarded door to a room below it. In the gable end is a small-pane window to the stock room and, on the R, an opening with sliding shutters through which timber passed directly on to the interior rack bench. The W wall has 3 small-pane windows similar to the E wall. Projecting in the centre is a drive wheel for tractor-power take off.
The overshot waterwheel is mounted above a stone wheelpit that is open at one end. The wheel is of cast-iron with replacement pressed-steel buckets, and was cast for J. Davies of Dolgoch, Llanbrynmair, by the Eagle Foundry in Aberystwyth, whose heart-shaped symbol is on the main axle. Power is transmitted by means of a ring gear to a drive shaft that passes over the yard and into the building. The timber water launder was rebuilt c1980s, and there is a short cobbled tail race.
