The archaeological remains of the grubenhaus excavated at New Bewick consisted of a sub-rectangular pit dug into sand and measuring approximately 4.7 m in length, 3.9 m in width, and 0.5 m in depth.

The pit was oriented North-South, and its edges appeared irregular only when affected by soil erosion. Apart from that, the edges were sharp. The sides of the pit were steep and its bottom surface was flat. On this surface, two post holes were placed in the middle of the short sides, against their edges. The post hole to the South was double and its depth reached 0.95 m, while the one to the North was single and 0.75 m deep. The archaeologists who directed the site’s excavation interpreted these irregularities as a result of later erosion in the western area of the pit rather than to a significantly asymmetrical design. Approximately 20 to 30 unfired and fired loomweights, ring-shaped and broken, were found inside the pit. They laid on a surface identified by the archaeologists as the possible level of use of the building, due to the presence of silty clay and charcoal patches. The grubenhaus seems to have been abandoned for a certain period and then demolished. The only other data about its elevation is constituted by fragments of daub from the demolition levels that filled the pit.

Three pits, possibly pot-holes, were found to the South-West of the grubenhaus, and another one to its North. Bigger pits, of which two were connected by a gully, were identified to the West.
