Blaen Glasffrwd longhouse is a post-medieval structure located in Wales and protected by Cadw under reference CD206. The building belongs to a widespread tradition of domestic architecture found throughout Wales and the Welsh borderlands, where livestock and human inhabitants shared a single elongated structure under one roof, with the byre at one end and living quarters at the other.
The site stands on bedrock of Llandovery age, composed of interbedded sandstone and conglomerate, which would have provided suitable stone for the building's construction and walls. This geology is typical of mid-Wales, where such sedimentary rocks weathered into workable building material for local structures. The valley location at Blaen Glasffrwd would have offered shelter and access to water for both domestic use and livestock.
Longhouses of this type continued in use well into the modern period in upland Wales, representing a practical response to the requirements of pastoral farming communities. The Cadw designation recognises the building's significance as evidence of traditional Welsh rural settlement patterns and domestic organisation during the post-medieval era.
