Little direct evidence remains for the original 1090s roof structure of Westminster Hall. The prevailing view has been that, until its replacement in the 1390s, the interior must have been divided by aisles to support the very wide span of the roof. This view was challenged by Roland Harris and Daniel Miles in 2013, with a proposal for a clear-spanning roof structure, which would be quite exceptional for the period. This article uses evidence from both Westminster and comparable buildings to explore the feasibility of alternative structural forms in some detail, with reconstruction drawings. Significant problems are encountered with all of the alternative forms, leading to a strong affirmation of the theory proposed by Harris and Miles. The Norman hall at Westminster was planned and roofed without internal arcades or piers, whether of timber or masonry. Westminster Hall thus played no part in the development of the English aisled hall.

威斯敏斯特大厅 1090 年代原始屋顶结构几乎没有直接证据。普遍的看法是，在 1390 年代更换之前，内部一定被过道分隔，以支撑非常宽的屋顶跨度。这种观点在 2013 年受到罗兰哈里斯和丹尼尔迈尔斯的挑战，他们提出了一个跨度屋顶结构的提议，这在那个时期是非常特别的。本文使用来自威斯敏斯特和类似建筑的证据，通过重建图纸详细探讨替代结构形式的可行性。所有替代形式都遇到了重大问题，导致对 Harris 和 Miles 提出的理论的强烈肯定。威斯敏斯特的诺曼礼堂经过规划和屋顶，没有内部拱廊或码头，无论是木材还是砖石。因此，威斯敏斯特大厅在英式走道大厅的发展中没有发挥任何作用。
