Several mortar stones were found, one with three mortars linearly arranged. Also a stone with two bearings much polished by iron axles. This building is sometimes known as the mill. It is the same date as week ford 2. They had joint use of the water supply, and detail of their door jambs, which are grooved to take the wooden post. Overshot water wheel. Part of a broken mouldstone with a sample mould was found in the east wall of the furnace, and anvil stones were also found. The entrance is on the east side and there are extensions at the south west and south east corners. Building(leng(max 6.25m, min 5.6m), widt 4m), wheel est(diam 3m, widt 610mm), furnace widt 1.22m, bearings diam 41mm (worth,1940 pp.214-5).

Surveyed in 1991. An irregular, 4-sided structure, levelled into hillslope with south rear wall acting as a revetment. Internal dimensions 4m north-south by 6.3m and 5.3m east-west. Walls, of large undressed moorstones stand a maximum 2m high. Interior is strewn with masonry. A granite-lined recess, 1.3m by 1m deep into south wall, could be a fireplace or an ore-shute. Within it lies a large fallen slab, 0.6m wide, into which a lateral groove has been cut. Its purpose is unknown. A second slab, 1.2m by 0.8m lies on the ground, level with the top of the wall.
Entrance, in the northern wall, is 0.8m wide. Western door jamb has a vertical groove which would have accommodated a wooden door lining. A flat-topped stone forms the threshold. An exceptionally well-preserved wheelpit occupies the entire width of the exterior of the east wall. It is 0.6m wide internally and survives to 1.6m deep. Its south-east corner has been deliberately breached to allow water to flow through it from a leat which meets it at an acute angle from the east. The area immediately south and to the rear of the wheelpit is strewn with large fallen boulders which formed the final support for a wooden launder.
The main leat embankment stands 5m south of the wheelpit. It is an earthen bank 13m long, with traces of walling on the exterior to the west. The fact that the tailrace of this mill makes an obvious detour around lower mill might suggest that this is a later build, with lower mill still in use. However, since the leat of lower mill breaches upper mill's wheelpit, it might equally be argued that upper mill is earlier. Despite the lack of clarity for the earliest phase, the existence of independent water supplies suggests both could have functioned together during later phases.
The interior contains no visible mortarstones, but several lie scattered around the exterior. One at least still lies where Burnard observed it, inside the wheelpit. There is no evidence of a furnace or a mouldstone, and given the fine condition of the structure and that the floor debris appears comparatively shallow, one would expect such features to be visible had they existed at the time of abandonment.
