Llwyn-glas is a late eighteenth century stone-built, single-storey, 2-unit, end-chimney cottage with a thatch roof under corrugated-iron. It has wattle & daub partitions and wattle underthatch. There is a central-entry passage with a pantry separating a narrow heated parlour from the larger kitchen with fireplace.
