Remains of Trentham Hall: The Grand Entrance and conservatory

The remains of the grand entrance and conservatory at Trentham Hall are a significant example of Italianate design, created by the architect Sir Charles Barry and built between 1833 and 1842 by James Trubshaw. The structure is primarily brick, rendered with stucco architectural detailing, with stone ashlar used for the porte-cochère and balustrade. Timber-framed windows are a notable feature.

The grand west entrance is centred around a porte-cochère, with curved arcades extending to either side, forming a semi-circular or C-shaped plan. A single-storey, five-bay wing extends to the south. The north wing has been demolished. The porte-cochère has round-arched openings, each with a scrolled keystone and vermiculated quoins. These arches are flanked by pairs of three-quarter Ionic columns, using alternating bands of rusticated and plain stone to support the entablature. The parapet wall is topped with a stone balustrade, and incorporates stone carvings of the family's coat of arms, sculpted by Charles Smith and framed by banded pilasters topped with finials.

The Ionic order is also used on the curved arcades and the south wing, with three-quarter Ionic columns dividing full-height windows that have moulded, round-arched heads and scrolled keystones. The balustrade above the entablature incorporates pedestals topped with vases. The east elevation of the arcade, facing an internal courtyard, showcases the Corinthian order. A round-headed central window is flanked by pairs of Corinthian columns, with a curved Corinthian colonnade on either side, terminating in three round-arched windows framed by Corinthian pilasters. This elevation also has pedestals topped with vases.

Inside the curved arcades, the internal walls feature scrolled keystones over the round-arched window heads and Corinthian pilasters between the windows. A decorative ironwork doorframe is visible at the east doorway of the south arcade, which would have provided access to the connected state rooms.
