A single storey lofted cottage, thought to be sixteenth century, with an agricultural building, once a mill of some kind, attached.
The cottage faces north. Its walls, limewashed or roughcast, are of uncoursed stone rubble on a boulder foundation, under a modern gabled roof. The original doorway is now a window. The existing windows are thought to be modern replacements in original openings.
There is a central fireplace dividing the interior into two rooms, both of which show a cruck pair. The present lofts are modern, but a window in the east gable is thought to have lit an original loft.
A single bay building is added on the east end, sharing a common roof. This has an arched opening to the front and an iron drive wheel over a leat at the rear.
Blaenglasgwmuchaf (Blaen-y-glasgwm) is an upland farmhouse of late medieval origin. The house is downslope sited, rubble walled, and retains several cruck trusses with lapped collars and tie-beams. The crucks defined a four-bay range, presumably a peasant hall-house with single-bayed hall. The inserted fireplace has created a house of lobby-entry type with the large fireplace heating the former hall with lofted inner rooms beyond. The former doorway into the cross-passage has been converted to a window. The C17th roof raising is probably contemporary with the inserted fireplace. Blaenglasgwm was part of the Gwydir estate in the early C17th. Plan and description in RCAHMW, Caernarvonshire Inventory, Volume I: East (1956), p.174, mon. 620 and fig. 169, plate 63. NPRN 26032.
