A ruined rectangular building located with the large area of tin streamworks on the east side of Blacklane Brook, is a possible tinners' building or lodge, to which a post-medieval date may be assumed, though it could possibly be earlier. The uneven walls are constructed from random granite boulders, standing to a maximum height of 0.8 metres. The dimensions are apprximately 5.3 metres by 2.5 metres but the position of the entrance has not survived.

(03/07/2020) Aside from some minor encroachment from Compact Rush there appears to be no significant factors impacting on this site. The only possible position for a doorway would appear to be central in the north wall although much wall tumble has now disguised that position. The, shorter, west and east walls appear to be complete and the complete south wall is also backed by a substantial streamwork bank. Condition good.

Rectangular building shown on modern mapping.

This rectangular building at SX 62956691 measures 5.2 metres by 2.5 metres internally. It lies against the river cliff on the east bank of the Blacklane Brook at 410 metres above OD. The walls, 0.9 metres wide, are built of coursed small boulders and incorporate a large slab, 1.5 metres long. The walls stand to a height of 1.5 metres and are in a poor condition. There is no indication of an entrance, and the absence of a leat, wheelpit, mould or mortar stones suggests that it is not a blowing house but probably a tinner's hut of medieval or later date.
