The staircase itself and the doorways are made of oak, and the decoration is in plasterwork and strapwork. Above the staircase is a glass-walled domed ceiling. On the upper floor, the South Bay Bedroom was originally the principal bedroom. It contains a collection of watercolours by Elizabeth Ashbrook. The Exhibition Room occupies a former dressing room and contains information about the history of the hall. The Emperor's Room is named after Prince Louis Napoleon, later Napoleon III, who stayed in the hall during the winter of 1847–48. It contains watercolours by Piers Egerton-Warburton, including pictures of timber-framed buildings in Northwest England and views of Arley and Great Budworth. The final room on the upper floor open to the public is the General's Room, dedicated to the memory of Sir George Higginson, the great-grandfather of the present Viscount Ashbrook, and contains memorabilia relating to him. Leading back to the ground floor is the Small Staircase, with its balustrade of oak capped with mahogany. Rowland Egerton-Warburton, influenced by the Oxford Movement, decided to add a Gothic chapel to the north-east of the house, and commissioned Anthony Salvin for the design. The chapel was consecrated in September 1845. In 1856–57 a north aisle and entrance porch designed by George Street were added. The chapel is dedicated to St Mary. The chapel is built in red sandstone and rendered brick with a slate and tile roof. The sandstone came from quarries in Runcorn. Its plan consists of a four-bay nave with a north aisle, a two-bay chancel, a porch and a bell turret to the north. On the east front is a canted oriel window supported on a buttress. The bell turret is octagonal with eight lancet openings at the bell stage and is surmounted by a red-tiled spirelet. Inside the chapel is a richly painted iron screen, which hides the central heating, and three corona-shaped chandeliers. The stained glass in the east window, dated 1895, is by Kempe. The font is a richly carved stone bowl on a cluster of marble columns. In the chancel is a piscina and a triple sedilia. The first gardens were created in the 18th century by Sir Peter Warburton, 4th baronet, who developed pleasure grounds, a walled kitchen garden and a landscape park.
