In c.875-900 rectangular timber structure was erected at the western end of the site. The south east wall of this building was fairly substantial and showed evidence of a phase of alteration after construction.

Phase 1 was represented by a narrow regular slot (context 203) 80cm wide and 30cm deep. It was filled with soil stained black with charcoal powder and many lumps of slag, and held 3 upright posts slightly offset to the west and two posts. Within the centre of the slot. The latter may have formed an entrance at the junction with the southwest wall. Presumably the slot held either a narrow sleeper beam with vertical timbers set into it, or closely spaced vertical planking.
In Phase 2 the narrow slot was replaced with a wider shallow foundation of loosely packed re-used Roman flint and tile rubbl, set lightly west and internally to the original slot. This foundation probably served as a ground sill for a timber sleeper, or perhaps as a working platform. Elsewhere the phase of modification is less clear. It would appear unusual to have a structure with a mixture of earthfast foundations and ground sills. However, this same arrangement was noted at Porchester.

A number of postholes along the south west wall of this building utilised slag as post packing. This confirms related to S8 of Period 6IV.

The floor was compact earth. Centrally placed hearth (context 119) was constructed of re-used Roman Brick and tile set in a shallow scoop. Evidence of fire was constricted to a few flecks of charcoal and decayed fired clay between tiles, and there was no indication of intense heat on the tiles. South of the hearth a scatter of ragstone, Roman tile and slag with some bone may have indicated the position of a destroyed working surface or platform. There was nothing in the destruction levels of the building to indicate thetype of roofing material used.

To the North east was a curving gully (context 205) presumably a property boundary. Slags and hammerscale recovered from comtemporary pits adjacent to this structure provide ample evidence of smithing on or more likely near the site, although significantly there was no hammer scale or ash trodden into the floor surface.

Particularly significant is the proximity of Pit 105 south east of the wall trench. The large hollow surrounding the shaft of this pit might be taken to indicate a working platform dug to allow material to be removed from the base of the pit.
